Use CMake EXPORT sets with namespaces (llama::, ggml::) instead of manually constructed IMPORTED targets in config files. Install config files to CMAKE_INSTALL_DATAROOTDIR and headers into a llama/ subdirectory. Use BUILD_INTERFACE/INSTALL_INTERFACE generator expressions for include paths. Also add GGML_VULKAN_DISABLE_COOPMAT{,2} options, OpenCL pkg-config discovery in ggml-config, and license file copying in CI builds. cmake: Fix building common when curl is off.

+ +Vulkan(R) Memory Allocator (VMA) is a software library for developers who use the Vulkan graphics API in their code. +It is written in C++. + +What is the license of VMA? + +VMA is licensed under MIT, which means it is open source and free software. + +What is the purpose of VMA? + +VMA helps with handling one aspect of Vulkan usage, which is device memory management - +allocation of `VkDeviceMemory` objects, and creation of `VkBuffer` and `VkImage` objects. + +Do I need to use VMA? + +You don't need to, but it may be beneficial in many cases. +Vulkan is a complex and low-level API, so libraries like this that abstract certain aspects of the API +and bring them to a higher level are useful. +When developing any non-trivial Vulkan application, you likely need to use a memory allocator. +Using VMA can save time compared to implementing your own. + +When should I not use VMA? + +While VMA is useful for most applications that use the Vulkan API, there are cases +when it may be a better choice not to use it. +For example, if the application is very simple, e.g. serving as a sample or a learning exercise +to help you understand or teach others the basics of Vulkan, +and it creates only a small number of buffers and images, then including VMA may be an overkill. +Developing your own memory allocator may also be a good learning exercise. + +What are the benefits of using VMA? + +-# VMA helps in choosing the optimal memory type for your resource (buffer or image). + In Vulkan, we have a two-level hierarchy of memory heaps and types with different flags, + and each device can expose a different set of those. + Implementing logic that would select the best memory type on each platform is a non-trivial task. + VMA does that, expecting only a high-level description of the intended usage of your resource. + For more information, see \subpage choosing_memory_type. +-# VMA allocates large blocks of `VkDeviceMemory` and sub-allocates parts of them for your resources. + Allocating a new block of device memory may be a time-consuming operation. + Some platforms also have a limit on the maximum number of those blocks (`VkPhysicalDeviceLimits::maxMemoryAllocationCount`) + as low as 4096, so allocating a separate one for each resource is not an option. + Sub-allocating parts of a memory block requires implementing an allocation algorithm, + which is a non-trivial task. + VMA does that, using an advanced and efficient algorithm that works well in various use cases. +-# VMA offers a simple API that allows creating buffers and textures within one function call. + In Vulkan, the creation of a resource is a multi-step process. + You need to create a `VkBuffer` or `VkImage`, ask it for memory requirements, + allocate a `VkDeviceMemory` object, and finally bind the resource to the memory block. + VMA does that automatically under a simple API within one function call: vmaCreateBuffer(), vmaCreateImage(). + +The library is doing much more under the hood. +For example, it respects limits like `bufferImageGranularity`, `nonCoherentAtomSize`, +and `VkMemoryDedicatedRequirements` automatically, so you don't need to think about it. + +Which version should I pick? + +You can just pick [the latest version from the "master" branch](https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator). +It is kept in a good shape most of the time, compiling and working correctly, +with no compatibility-breaking changes and no unfinished code. + +If you want an even more stable version, you can pick +[the latest official release](https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator/releases). +Current code from the master branch is occasionally tagged as a release, +with [CHANGELOG](https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator/blob/master/CHANGELOG.md) +carefully curated to enumerate all important changes since the previous version. + +The library uses [Semantic Versioning](https://semver.org/), +which means versions that only differ in the patch number are forward and backward compatible +(e.g., only fixing some bugs), while versions that differ in the minor number are backward compatible +(e.g., only adding new functions to the API, but not removing or changing existing ones). + +How to integrate it with my code? + +VMA is an STB-style single-header C++ library. + +You can pull the entire GitHub repository, e.g. using Git submodules. +The repository contains ancillary files like the Cmake script, Doxygen config file, +sample application, test suite, and others. +You can compile it as a library and link with your project. + +However, a simpler way is taking the single file "include/vk_mem_alloc.h" and including it in your project. +This extensive file contains all you need: a copyright notice, +declarations of the public library interface (API), its internal implementation, +and even the documentation in form of Doxygen-style comments. + +The "STB style" means not everything is implemented as inline functions in the header file. +You need to extract the internal implementation using a special macro. +This means that in every .cpp file where you need to use the library you should +`#include "vk_mem_alloc.h"` to include its public interface, +but additionally in exactly one .cpp file you should `#define VMA_IMPLEMENTATION` +before this `#include` to enable its internal implementation. +For more information, see [Project setup](@ref quick_start_project_setup). + +Does the library work with C or C++? + +The internal implementation of VMA is written in C++. +It is distributed in the source format, so you need a compiler supporting at least C++14 to build it. + +However, the public interface of the library is written in C - using only enums, structs, and global functions, +in the same style as Vulkan, so you can use the library in the C code. + +I am not a fan of modern C++. Can I still use it? + +Very likely yes. +We acknowledge that many C++ developers, especially in the games industry, +do not appreciate all the latest features that the language has to offer. + +- VMA doesn't throw or catch any C++ exceptions. + It reports errors by returning a `VkResult` value instead, just like Vulkan. + If you don't use exceptions in your project, your code is not exception-safe, + or even if you disable exception handling in the compiler options, you can still use VMA. +- VMA doesn't use C++ run-time type information like `typeid` or `dynamic_cast`, + so if you disable RTTI in the compiler options, you can still use the library. +- VMA uses only a limited subset of standard C and C++ library. + It doesn't use STL containers like `std::vector`, `map`, or `string`, + either in the public interface nor in the internal implementation. + It implements its own containers instead. +- If you don't use the default heap memory allocator through `malloc/free` or `new/delete` + but implement your own allocator instead, you can pass it to VMA and + the library will use your functions for every dynamic heap allocation made internally, + as well as passing it further to Vulkan functions. For details, see [Custom host memory allocator](@ref custom_memory_allocator). + +Is it available for other programming languages? + +VMA is a C++ library with C interface in similar style as Vulkan. +An object-oriented C++ wrapper or bindings to other programming languages are out of scope of this project, +but they are welcome as external projects. +Some of them are listed in [README.md, "See also" section](https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator?tab=readme-ov-file#see-also), +including binding to C++, Python, Rust, and Haskell. +Before using any of them, please check if they are still maintained and updated to use a recent version of VMA. + +What platforms does it support? + +VMA relies only on Vulkan and some parts of the standard C and C++ library, +so it supports any platform where a C++ compiler and Vulkan are available. +It is developed mostly on Microsoft(R) Windows(R), +but it has been successfully used in Linux(R), MacOS, Android, and even FreeBSD and Raspberry Pi. + +Does it only work on AMD GPUs? + +No! While VMA is published by AMD, it works on any GPU that supports Vulkan, +whether a discrete PC graphics card, a processor integrated graphics, or a mobile SoC. +It doesn't give AMD GPUs any advantage over any other GPUs. + +What Vulkan versions and extensions are supported? + +VMA is updated to support the latest versions of Vulkan. +It currently supports Vulkan up to 1.4. +The library also supports older versions down to the first release of Vulkan 1.0. +Defining a higher minimum version support would help simplify the code, +but we acknowledge that developers on some platforms like Android still use older versions, +so the support is provided for all of them. + +Among many extensions available for Vulkan, only a few interact with memory management. +VMA can automatically take advantage of them. Some of them are: +VK_EXT_memory_budget, VK_EXT_memory_priority, VK_KHR_external_memory_win32, and VK_KHR_maintenance* +extensions that are later promoted to the new versions of the core Vulkan API. + +To use them, it is your responsibility to validate if they are available on the current system and if so, +enable them while creating the Vulkan device object. +You also need to pass appropriate #VmaAllocatorCreateFlagBits to inform VMA that they are enabled. +Then, the library will automatically take advantage of them. +For more information and the full list of supported extensions, see [Enabling extensions](@ref quick_start_initialization_enabling_extensions). + +Does it support other graphics APIs, like Microsoft DirectX(R) 12? + +No, but we offer an equivalent library for DirectX 12: +[D3D12 Memory Allocator](https://github.com/GPUOpen-LibrariesAndSDKs/D3D12MemoryAllocator). +It uses the same core allocation algorithm. +It also shares many features with VMA, like the support for custom pools and virtual allocator. +However, it is not identical in terms of the features supported. +Its API also looks different, because while the interface of VMA is similar in style to Vulkan, +the interface of D3D12MA is similar to DirectX 12. + +Is the library lightweight? + +It depends on how you define it. +VMA is implemented with high-performance and real-time applications like video games in mind. +The CPU performance overhead of using this library is low. +It uses a high-quality allocation algorithm called Two-Level Segregated Fit (TLSF), +which in most cases can find a free place for a new allocation in few steps. +The library also doesn't perform too many CPU heap allocations. +In many cases, the allocation happens with 0 new CPU heap allocations performed by the library. +Even the creation of a #VmaAllocation object doesn't typically feature an CPU allocation, +because these objects are returned out of a dedicated memory pool. + +On the other hand, however, VMA needs some extra memory and extra time +to maintain the metadata about the occupied and free regions of the memory blocks, +and the algorithms and data structures used must be generic enough to work well in most cases. +If you develop your program for a very resource-constrained platform, +a custom allocator simpler than VMA may be a better choice. + +Does it have a documentation? + +Yes! VMA comes with full documentation of all elements of the API (functions, structures, enums), +as well as many generic chapters that provide an introduction, +describe core concepts of the library, good practices, etc. +The entire documentation is written in form of code comments inside "vk_mem_alloc.h", in Doxygen format. +You can access it in multiple ways: + +- Browsable online: https://gpuopen-librariesandsdks.github.io/VulkanMemoryAllocator/html/ +- Local HTML pages available after you clone the repository and open file "docs/html/index.html". +- You can rebuild the documentation in HTML or some other format from the source code using Doxygen. + Configuration file "Doxyfile" is part of the repository. +- Finally, you can just read the comments preceding declarations of any public functions of the library. + +Is it a mature project? + +Yes! The library is in development since June 2017, has over 1000 commits, over 400 issue tickets +and pull requests (most of them resolved), and over 70 contributors. +It is distributed together with Vulkan SDK. +It is used by many software projects, including some large and popular ones like Qt or Blender, +as well as some AAA games. +According to the [LunarG 2024 Ecosystem Survey](https://www.lunarg.com/2024-ecosystem-survey-progress-report-released/), +it is used by over 50% of Vulkan developers. + +How can I contribute to the project? + +If you have an idea for improvement or a feature request, +you can go to [the library repository](https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator) +and create an Issue ticket, describing your idea. +You can also implement it yourself by forking the repository, making changes to the code, +and creating a Pull request. + +If you want to ask a question, you can also create a ticket the same way. +Before doing this, please make sure you read the relevant part of the Vulkan specification and VMA documentation, +where you may find the answers to your question. + +If you want to report a suspected bug, you can also create a ticket the same way. +Before doing this, please put some effort into the investigation of whether the bug is really +in the library and not in your code or in the Vulkan implementation (the GPU driver) on your platform: + +- Enable Vulkan validation layer and make sure it is free from any errors. +- Make sure `VMA_ASSERT` is defined to an implementation that can report a failure and not ignore it. +- Try making your allocation using pure Vulkan functions rather than VMA and see if the bug persists. + +I found some compilation warnings. How can we fix them? + +Seeing compiler warnings may be annoying to some developers, +but it is a design decision to not fix all of them. +Due to the nature of the C++ language, certain preprocessor macros can make some variables unused, +function parameters unreferenced, or conditional expressions constant in some configurations. +The code of this library should not be bigger or more complicated just to silence these warnings. +It is recommended to disable such warnings instead. +For more information, see [Features not supported](@ref general_considerations_features_not_supported). + +However, if you observe a warning that is really dangerous, e.g., +about an implicit conversion from a larger to a smaller integer type, please report it and it will be fixed ASAP. + + +\page quick_start Quick start + +\section quick_start_project_setup Project setup + +Vulkan Memory Allocator comes in form of a "stb-style" single header file. +While you can pull the entire repository e.g. as Git module, there is also Cmake script provided, +you don't need to build it as a separate library project. +You can add file "vk_mem_alloc.h" directly to your project and submit it to code repository next to your other source files. + +"Single header" doesn't mean that everything is contained in C/C++ declarations, +like it tends to be in case of inline functions or C++ templates. +It means that implementation is bundled with interface in a single file and needs to be extracted using preprocessor macro. +If you don't do it properly, it will result in linker errors. + +To do it properly: + +-# Include "vk_mem_alloc.h" file in each CPP file where you want to use the library. + This includes declarations of all members of the library. +-# In exactly one CPP file define following macro before this include. + It enables also internal definitions. + +\code +#define VMA_IMPLEMENTATION +#include "vk_mem_alloc.h" +\endcode + +It may be a good idea to create dedicated CPP file just for this purpose, e.g. "VmaUsage.cpp". + +This library includes header ``, which in turn +includes `` on Windows. If you need some specific macros defined +before including these headers (like `WIN32_LEAN_AND_MEAN` or +`WINVER` for Windows, `VK_USE_PLATFORM_WIN32_KHR` for Vulkan), you must define +them before every `#include` of this library. +It may be a good idea to create a dedicate header file for this purpose, e.g. "VmaUsage.h", +that will be included in other source files instead of VMA header directly. + +This library is written in C++, but has C-compatible interface. +Thus, you can include and use "vk_mem_alloc.h" in C or C++ code, but full +implementation with `VMA_IMPLEMENTATION` macro must be compiled as C++, NOT as C. +Some features of C++14 are used and required. Features of C++20 are used optionally when available. +Some headers of standard C and C++ library are used, but STL containers, RTTI, or C++ exceptions are not used. + + +\section quick_start_initialization Initialization + +VMA offers library interface in a style similar to Vulkan, with object handles like #VmaAllocation, +structures describing parameters of objects to be created like #VmaAllocationCreateInfo, +and errors codes returned from functions using `VkResult` type. + +The first and the main object that needs to be created is #VmaAllocator. +It represents the initialization of the entire library. +Only one such object should be created per `VkDevice`. +You should create it at program startup, after `VkDevice` was created, and before any device memory allocator needs to be made. +It must be destroyed before `VkDevice` is destroyed. + +At program startup: + +-# Initialize Vulkan to have `VkInstance`, `VkPhysicalDevice`, `VkDevice` object. +-# Fill VmaAllocatorCreateInfo structure and call vmaCreateAllocator() to create #VmaAllocator object. + +Only members `physicalDevice`, `device`, `instance` are required. +However, you should inform the library which Vulkan version do you use by setting +VmaAllocatorCreateInfo::vulkanApiVersion and which extensions did you enable +by setting VmaAllocatorCreateInfo::flags. +Otherwise, VMA would use only features of Vulkan 1.0 core with no extensions. +See below for details. + +\subsection quick_start_initialization_selecting_vulkan_version Selecting Vulkan version + +VMA supports Vulkan version down to 1.0, for backward compatibility. +If you want to use higher version, you need to inform the library about it. +This is a two-step process. + +Step 1: Compile time. By default, VMA compiles with code supporting the highest +Vulkan version found in the included `` that is also supported by the library. +If this is OK, you don't need to do anything. +However, if you want to compile VMA as if only some lower Vulkan version was available, +define macro `VMA_VULKAN_VERSION` before every `#include "vk_mem_alloc.h"`. +It should have decimal numeric value in form of ABBBCCC, where A = major, BBB = minor, CCC = patch Vulkan version. +For example, to compile against Vulkan 1.2: + +\code +#define VMA_VULKAN_VERSION 1002000 // Vulkan 1.2 +#include "vk_mem_alloc.h" +\endcode + +Step 2: Runtime. Even when compiled with higher Vulkan version available, +VMA can use only features of a lower version, which is configurable during creation of the #VmaAllocator object. +By default, only Vulkan 1.0 is used. +To initialize the allocator with support for higher Vulkan version, you need to set member +VmaAllocatorCreateInfo::vulkanApiVersion to an appropriate value, e.g. using constants like `VK_API_VERSION_1_2`. +See code sample below. + +\subsection quick_start_initialization_importing_vulkan_functions Importing Vulkan functions + +You may need to configure importing Vulkan functions. There are 4 ways to do this: + +-# **If you link with Vulkan static library** (e.g. "vulkan-1.lib" on Windows): + - You don't need to do anything. + - VMA will use these, as macro `VMA_STATIC_VULKAN_FUNCTIONS` is defined to 1 by default. +-# **If you want VMA to fetch pointers to Vulkan functions dynamically** using `vkGetInstanceProcAddr`, + `vkGetDeviceProcAddr` (this is the option presented in the example below): + - Define `VMA_STATIC_VULKAN_FUNCTIONS` to 0, `VMA_DYNAMIC_VULKAN_FUNCTIONS` to 1. + - Provide pointers to these two functions via VmaVulkanFunctions::vkGetInstanceProcAddr, + VmaVulkanFunctions::vkGetDeviceProcAddr. + - The library will fetch pointers to all other functions it needs internally. +-# **If you fetch pointers to all Vulkan functions in a custom way**: + - Define `VMA_STATIC_VULKAN_FUNCTIONS` and `VMA_DYNAMIC_VULKAN_FUNCTIONS` to 0. + - Pass these pointers via structure #VmaVulkanFunctions. +-# **If you use [volk library](https://github.com/zeux/volk)**: + - Define `VMA_STATIC_VULKAN_FUNCTIONS` and `VMA_DYNAMIC_VULKAN_FUNCTIONS` to 0. + - Use function vmaImportVulkanFunctionsFromVolk() to fill in the structure #VmaVulkanFunctions. + For more information, see the description of this function. + +\subsection quick_start_initialization_enabling_extensions Enabling extensions + +VMA can automatically use following Vulkan extensions. +If you found them available on the selected physical device and you enabled them +while creating `VkInstance` / `VkDevice` object, inform VMA about their availability +by setting appropriate flags in VmaAllocatorCreateInfo::flags. + +Vulkan extension | VMA flag +------------------------------|----------------------------------------------------- +VK_KHR_dedicated_allocation | #VMA_ALLOCATOR_CREATE_KHR_DEDICATED_ALLOCATION_BIT +VK_KHR_bind_memory2 | #VMA_ALLOCATOR_CREATE_KHR_BIND_MEMORY2_BIT +VK_KHR_maintenance4 | #VMA_ALLOCATOR_CREATE_KHR_MAINTENANCE4_BIT +VK_KHR_maintenance5 | #VMA_ALLOCATOR_CREATE_KHR_MAINTENANCE5_BIT +VK_EXT_memory_budget | #VMA_ALLOCATOR_CREATE_EXT_MEMORY_BUDGET_BIT +VK_KHR_buffer_device_address | #VMA_ALLOCATOR_CREATE_BUFFER_DEVICE_ADDRESS_BIT +VK_EXT_memory_priority | #VMA_ALLOCATOR_CREATE_EXT_MEMORY_PRIORITY_BIT +VK_AMD_device_coherent_memory | #VMA_ALLOCATOR_CREATE_AMD_DEVICE_COHERENT_MEMORY_BIT +VK_KHR_external_memory_win32 | #VMA_ALLOCATOR_CREATE_KHR_EXTERNAL_MEMORY_WIN32_BIT + +Example with fetching pointers to Vulkan functions dynamically: + +\code +#define VMA_STATIC_VULKAN_FUNCTIONS 0 +#define VMA_DYNAMIC_VULKAN_FUNCTIONS 1 +#include "vk_mem_alloc.h" + +... + +VmaVulkanFunctions vulkanFunctions = {};

+ +VkBuffer buffer; +VmaAllocation allocation; +vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr); +\endcode + +Don't forget to destroy your buffer and allocation objects when no longer needed: + +\code +vmaDestroyBuffer(allocator, buffer, allocation); +\endcode + +If you need to map the buffer, you must set flag +#VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT or #VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT +in VmaAllocationCreateInfo::flags. +There are many additional parameters that can control the choice of memory type to be used for the allocation +and other features. +For more information, see documentation chapters: @ref choosing_memory_type, @ref memory_mapping. + + +\page choosing_memory_type Choosing memory type + +Physical devices in Vulkan support various combinations of memory heaps and +types. Help with choosing correct and optimal memory type for your specific +resource is one of the key features of this library. You can use it by filling +appropriate members of VmaAllocationCreateInfo structure, as described below. +You can also combine multiple methods. + +-# If you just want to find memory type index that meets your requirements, you + can use function: vmaFindMemoryTypeIndexForBufferInfo(), + vmaFindMemoryTypeIndexForImageInfo(), vmaFindMemoryTypeIndex(). +-# If you want to allocate a region of device memory without association with any + specific image or buffer, you can use function vmaAllocateMemory(). Usage of + this function is not recommended and usually not needed. + vmaAllocateMemoryPages() function is also provided for creating multiple allocations at once, + which may be useful for sparse binding. +-# If you already have a buffer or an image created, you want to allocate memory + for it and then you will bind it yourself, you can use function + vmaAllocateMemoryForBuffer(), vmaAllocateMemoryForImage(). + For binding you should use functions: vmaBindBufferMemory(), vmaBindImageMemory() + or their extended versions: vmaBindBufferMemory2(), vmaBindImageMemory2(). +-# If you want to create a buffer or an image, allocate memory for it, and bind + them together, all in one call, you can use function vmaCreateBuffer(), + vmaCreateImage(). + This is the easiest and recommended way to use this library! + +When using 3. or 4., the library internally queries Vulkan for memory types +supported for that buffer or image (function `vkGetBufferMemoryRequirements()`) +and uses only one of these types. + +If no memory type can be found that meets all the requirements, these functions +return `VK_ERROR_FEATURE_NOT_PRESENT`. + +You can leave VmaAllocationCreateInfo structure completely filled with zeros. +It means no requirements are specified for memory type. +It is valid, although not very useful. + +\section choosing_memory_type_usage Usage + +The easiest way to specify memory requirements is to fill member +VmaAllocationCreateInfo::usage using one of the values of enum #VmaMemoryUsage. +It defines high level, common usage types. +Since version 3 of the library, it is recommended to use #VMA_MEMORY_USAGE_AUTO to let it select best memory type for your resource automatically. + +For example, if you want to create a uniform buffer that will be filled using +transfer only once or infrequently and then used for rendering every frame as a uniform buffer, you can +do it using following code. The buffer will most likely end up in a memory type with +`VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT` to be fast to access by the GPU device. + +\code +VkBufferCreateInfo bufferInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO }; +bufferInfo.size = 65536; +bufferInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT; + +VmaAllocationCreateInfo allocInfo = {}; +allocInfo.usage = VMA_MEMORY_USAGE_AUTO; + +VkBuffer buffer; +VmaAllocation allocation; +vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr); +\endcode + +If you have a preference for putting the resource in GPU (device) memory or CPU (host) memory +on systems with discrete graphics card that have the memories separate, you can use +#VMA_MEMORY_USAGE_AUTO_PREFER_DEVICE or #VMA_MEMORY_USAGE_AUTO_PREFER_HOST. + +When using `VMA_MEMORY_USAGE_AUTO*` while you want to map the allocated memory, +you also need to specify one of the host access flags: +#VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT or #VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT. +This will help the library decide about preferred memory type to ensure it has `VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT` +so you can map it. + +For example, a staging buffer that will be filled via mapped pointer and then +used as a source of transfer to the buffer described previously can be created like this. +It will likely end up in a memory type that is `HOST_VISIBLE` and `HOST_COHERENT` +but not `HOST_CACHED` (meaning uncached, write-combined) and not `DEVICE_LOCAL` (meaning system RAM). + +\code +VkBufferCreateInfo stagingBufferInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO }; +stagingBufferInfo.size = 65536; +stagingBufferInfo.usage = VK_BUFFER_USAGE_TRANSFER_SRC_BIT; + +VmaAllocationCreateInfo stagingAllocInfo = {}; +stagingAllocInfo.usage = VMA_MEMORY_USAGE_AUTO; +stagingAllocInfo.flags = VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT; + +VkBuffer stagingBuffer; +VmaAllocation stagingAllocation; +vmaCreateBuffer(allocator, &stagingBufferInfo, &stagingAllocInfo, &stagingBuffer, &stagingAllocation, nullptr); +\endcode + +For more examples of creating different kinds of resources, see chapter \ref usage_patterns. +See also: @ref memory_mapping. + +Usage values `VMA_MEMORY_USAGE_AUTO*` are legal to use only when the library knows +about the resource being created by having `VkBufferCreateInfo` / `VkImageCreateInfo` passed, +so they work with functions like: vmaCreateBuffer(), vmaCreateImage(), vmaFindMemoryTypeIndexForBufferInfo() etc. +If you allocate raw memory using function vmaAllocateMemory(), you have to use other means of selecting +memory type, as described below. + +\note +Old usage values (`VMA_MEMORY_USAGE_GPU_ONLY`, `VMA_MEMORY_USAGE_CPU_ONLY`, +`VMA_MEMORY_USAGE_CPU_TO_GPU`, `VMA_MEMORY_USAGE_GPU_TO_CPU`, `VMA_MEMORY_USAGE_CPU_COPY`) +are still available and work same way as in previous versions of the library +for backward compatibility, but they are deprecated. + +\section choosing_memory_type_required_preferred_flags Required and preferred flags + +You can specify more detailed requirements by filling members +VmaAllocationCreateInfo::requiredFlags and VmaAllocationCreateInfo::preferredFlags +with a combination of bits from enum `VkMemoryPropertyFlags`. For example, +if you want to create a buffer that will be persistently mapped on host (so it +must be `HOST_VISIBLE`) and preferably will also be `HOST_COHERENT` and `HOST_CACHED`, +use following code: + +\code +VmaAllocationCreateInfo allocInfo = {}; +allocInfo.requiredFlags = VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT; +allocInfo.preferredFlags = VK_MEMORY_PROPERTY_HOST_COHERENT_BIT | VK_MEMORY_PROPERTY_HOST_CACHED_BIT; +allocInfo.flags = VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT | VMA_ALLOCATION_CREATE_MAPPED_BIT; + +VkBuffer buffer; +VmaAllocation allocation; +vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr); +\endcode + +A memory type is chosen that has all the required flags and as many preferred +flags set as possible. + +Value passed in VmaAllocationCreateInfo::usage is internally converted to a set of required and preferred flags, +plus some extra "magic" (heuristics). + +\section choosing_memory_type_explicit_memory_types Explicit memory types + +If you inspected memory types available on the physical device and you have +a preference for memory types that you want to use, you can fill member +VmaAllocationCreateInfo::memoryTypeBits. It is a bit mask, where each bit set +means that a memory type with that index is allowed to be used for the +allocation. Special value 0, just like `UINT32_MAX`, means there are no +restrictions to memory type index. + +Please note that this member is NOT just a memory type index. +Still you can use it to choose just one, specific memory type. +For example, if you already determined that your buffer should be created in +memory type 2, use following code: + +\code +uint32_t memoryTypeIndex = 2; + +VmaAllocationCreateInfo allocInfo = {}; +allocInfo.memoryTypeBits = 1U << memoryTypeIndex; + +VkBuffer buffer; +VmaAllocation allocation; +vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr); +\endcode + +You can also use this parameter to exclude some memory types. +If you inspect memory heaps and types available on the current physical device and +you determine that for some reason you don't want to use a specific memory type for the allocation, +you can enable automatic memory type selection but exclude certain memory type or types +by setting all bits of `memoryTypeBits` to 1 except the ones you choose. + +\code +// ... +uint32_t excludedMemoryTypeIndex = 2; +VmaAllocationCreateInfo allocInfo = {}; +allocInfo.usage = VMA_MEMORY_USAGE_AUTO; +allocInfo.memoryTypeBits = ~(1U << excludedMemoryTypeIndex); +// ... +\endcode + + +\section choosing_memory_type_custom_memory_pools Custom memory pools + +If you allocate from custom memory pool, all the ways of specifying memory +requirements described above are not applicable and the aforementioned members +of VmaAllocationCreateInfo structure are ignored. Memory type is selected +explicitly when creating the pool and then used to make all the allocations from +that pool. For further details, see \ref custom_memory_pools. + +\section choosing_memory_type_dedicated_allocations Dedicated allocations + +Memory for allocations is reserved out of larger block of `VkDeviceMemory` +allocated from Vulkan internally. That is the main feature of this whole library. +You can still request a separate memory block to be created for an allocation, +just like you would do in a trivial solution without using any allocator. +In that case, a buffer or image is always bound to that memory at offset 0. +This is called a "dedicated allocation". +You can explicitly request it by using flag #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT. +The library can also internally decide to use dedicated allocation in some cases, e.g.: + +- When the size of the allocation is large. +- When [VK_KHR_dedicated_allocation](@ref vk_khr_dedicated_allocation) extension is enabled + and it reports that dedicated allocation is required or recommended for the resource. +- When allocation of next big memory block fails due to not enough device memory, + but allocation with the exact requested size succeeds. + + +\page memory_mapping Memory mapping + +To "map memory" in Vulkan means to obtain a CPU pointer to `VkDeviceMemory`, +to be able to read from it or write to it in CPU code. +Mapping is possible only of memory allocated from a memory type that has +`VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT` flag. +Functions `vkMapMemory()`, `vkUnmapMemory()` are designed for this purpose. +You can use them directly with memory allocated by this library, +but it is not recommended because of following issue: +Mapping the same `VkDeviceMemory` block multiple times is illegal - only one mapping at a time is allowed. +This includes mapping disjoint regions. Mapping is not reference-counted internally by Vulkan. +It is also not thread-safe. +Because of this, Vulkan Memory Allocator provides following facilities: + +\note If you want to be able to map an allocation, you need to specify one of the flags +#VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT or #VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT +in VmaAllocationCreateInfo::flags. These flags are required for an allocation to be mappable +when using #VMA_MEMORY_USAGE_AUTO or other `VMA_MEMORY_USAGE_AUTO*` enum values. +For other usage values they are ignored and every such allocation made in `HOST_VISIBLE` memory type is mappable, +but these flags can still be used for consistency. + +\section memory_mapping_copy_functions Copy functions + +The easiest way to copy data from a host pointer to an allocation is to use convenience function vmaCopyMemoryToAllocation(). +It automatically maps the Vulkan memory temporarily (if not already mapped), performs `memcpy`, +and calls `vkFlushMappedMemoryRanges` (if required - if memory type is not `HOST_COHERENT`). + +It is also the safest one, because using `memcpy` avoids a risk of accidentally introducing memory reads +(e.g. by doing `pMappedVectors[i] += v`), which may be very slow on memory types that are not `HOST_CACHED`. + +\code +struct ConstantBuffer +{ + ... +}; +ConstantBuffer constantBufferData = ... + +VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO }; +bufCreateInfo.size = sizeof(ConstantBuffer); +bufCreateInfo.usage = VK_BUFFER_USAGE_TRANSFER_SRC_BIT; + +VmaAllocationCreateInfo allocCreateInfo = {}; +allocCreateInfo.usage = VMA_MEMORY_USAGE_AUTO; +allocCreateInfo.flags = VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT; + +VkBuffer buf; +VmaAllocation alloc; +vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, nullptr); + +vmaCopyMemoryToAllocation(allocator, &constantBufferData, alloc, 0, sizeof(ConstantBuffer)); +\endcode + +Copy in the other direction - from an allocation to a host pointer can be performed the same way using function vmaCopyAllocationToMemory(). + +\section memory_mapping_mapping_functions Mapping functions + +The library provides following functions for mapping of a specific allocation: vmaMapMemory(), vmaUnmapMemory(). +They are safer and more convenient to use than standard Vulkan functions. +You can map an allocation multiple times simultaneously - mapping is reference-counted internally. +You can also map different allocations simultaneously regardless of whether they use the same `VkDeviceMemory` block. +The way it is implemented is that the library always maps entire memory block, not just region of the allocation. +For further details, see description of vmaMapMemory() function. +Example: + +\code +// Having these objects initialized: +struct ConstantBuffer +{ + ... +}; +ConstantBuffer constantBufferData = ... + +VmaAllocator allocator = ... +VkBuffer constantBuffer = ... +VmaAllocation constantBufferAllocation = ... + +// You can map and fill your buffer using following code: + +void* mappedData; +vmaMapMemory(allocator, constantBufferAllocation, &mappedData); +memcpy(mappedData, &constantBufferData, sizeof(constantBufferData)); +vmaUnmapMemory(allocator, constantBufferAllocation); +\endcode + +When mapping, you may see a warning from Vulkan validation layer similar to this one: + +Mapping an image with layout VK_IMAGE_LAYOUT_DEPTH_STENCIL_ATTACHMENT_OPTIMAL can result in undefined behavior if this memory is used by the device. Only GENERAL or PREINITIALIZED should be used. + +It happens because the library maps entire `VkDeviceMemory` block, where different +types of images and buffers may end up together, especially on GPUs with unified memory like Intel. +You can safely ignore it if you are sure you access only memory of the intended +object that you wanted to map. + + +\section memory_mapping_persistently_mapped_memory Persistently mapped memory + +Keeping your memory persistently mapped is generally OK in Vulkan. +You don't need to unmap it before using its data on the GPU. +The library provides a special feature designed for that: +Allocations made with #VMA_ALLOCATION_CREATE_MAPPED_BIT flag set in +VmaAllocationCreateInfo::flags stay mapped all the time, +so you can just access CPU pointer to it any time +without a need to call any "map" or "unmap" function. +Example: + +\code +VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO }; +bufCreateInfo.size = sizeof(ConstantBuffer); +bufCreateInfo.usage = VK_BUFFER_USAGE_TRANSFER_SRC_BIT; + +VmaAllocationCreateInfo allocCreateInfo = {}; +allocCreateInfo.usage = VMA_MEMORY_USAGE_AUTO; +allocCreateInfo.flags = VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT | + VMA_ALLOCATION_CREATE_MAPPED_BIT; + +VkBuffer buf; +VmaAllocation alloc; +VmaAllocationInfo allocInfo; +vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, &allocInfo); + +// Buffer is already mapped. You can access its memory. +memcpy(allocInfo.pMappedData, &constantBufferData, sizeof(constantBufferData)); +\endcode + +\note #VMA_ALLOCATION_CREATE_MAPPED_BIT by itself doesn't guarantee that the allocation will end up +in a mappable memory type. +For this, you need to also specify #VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT or +#VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT. +#VMA_ALLOCATION_CREATE_MAPPED_BIT only guarantees that if the memory is `HOST_VISIBLE`, the allocation will be mapped on creation. +For an example of how to make use of this fact, see section \ref usage_patterns_advanced_data_uploading. + +\section memory_mapping_cache_control Cache flush and invalidate + +Memory in Vulkan doesn't need to be unmapped before using it on GPU, +but unless a memory types has `VK_MEMORY_PROPERTY_HOST_COHERENT_BIT` flag set, +you need to manually **invalidate** cache before reading of mapped pointer +and **flush** cache after writing to mapped pointer. +Map/unmap operations don't do that automatically. +Vulkan provides following functions for this purpose `vkFlushMappedMemoryRanges()`, +`vkInvalidateMappedMemoryRanges()`, but this library provides more convenient +functions that refer to given allocation object: vmaFlushAllocation(), +vmaInvalidateAllocation(), +or multiple objects at once: vmaFlushAllocations(), vmaInvalidateAllocations(). + +Regions of memory specified for flush/invalidate must be aligned to +`VkPhysicalDeviceLimits::nonCoherentAtomSize`. This is automatically ensured by the library. +In any memory type that is `HOST_VISIBLE` but not `HOST_COHERENT`, all allocations +within blocks are aligned to this value, so their offsets are always multiply of +`nonCoherentAtomSize` and two different allocations never share same "line" of this size. + +Also, Windows drivers from all 3 PC GPU vendors (AMD, Intel, NVIDIA) +currently provide `HOST_COHERENT` flag on all memory types that are +`HOST_VISIBLE`, so on PC you may not need to bother. + + +\page staying_within_budget Staying within budget + +When developing a graphics-intensive game or program, it is important to avoid allocating +more GPU memory than it is physically available. When the memory is over-committed, +various bad things can happen, depending on the specific GPU, graphics driver, and +operating system: + +- It may just work without any problems. +- The application may slow down because some memory blocks are moved to system RAM + and the GPU has to access them through PCI Express bus. +- A new allocation may take very long time to complete, even few seconds, and possibly + freeze entire system. +- The new allocation may fail with `VK_ERROR_OUT_OF_DEVICE_MEMORY`. +- It may even result in GPU crash (TDR), observed as `VK_ERROR_DEVICE_LOST` + returned somewhere later. + +\section staying_within_budget_querying_for_budget Querying for budget + +To query for current memory usage and available budget, use function vmaGetHeapBudgets(). +Returned structure #VmaBudget contains quantities expressed in bytes, per Vulkan memory heap. + +Please note that this function returns different information and works faster than +vmaCalculateStatistics(). vmaGetHeapBudgets() can be called every frame or even before every +allocation, while vmaCalculateStatistics() is intended to be used rarely, +only to obtain statistical information, e.g. for debugging purposes. + +It is recommended to use VK_EXT_memory_budget device extension to obtain information +about the budget from Vulkan device. VMA is able to use this extension automatically. +When not enabled, the allocator behaves same way, but then it estimates current usage +and available budget based on its internal information and Vulkan memory heap sizes, +which may be less precise. In order to use this extension: + +1. Make sure extensions VK_EXT_memory_budget and VK_KHR_get_physical_device_properties2 + required by it are available and enable them. Please note that the first is a device + extension and the second is instance extension! +2. Use flag #VMA_ALLOCATOR_CREATE_EXT_MEMORY_BUDGET_BIT when creating #VmaAllocator object. +3. Make sure to call vmaSetCurrentFrameIndex() every frame. Budget is queried from + Vulkan inside of it to avoid overhead of querying it with every allocation. + +\section staying_within_budget_controlling_memory_usage Controlling memory usage + +There are many ways in which you can try to stay within the budget. + +First, when making new allocation requires allocating a new memory block, the library +tries not to exceed the budget automatically. If a block with default recommended size +(e.g. 256 MB) would go over budget, a smaller block is allocated, possibly even +dedicated memory for just this resource. + +If the size of the requested resource plus current memory usage is more than the +budget, by default the library still tries to create it, leaving it to the Vulkan +implementation whether the allocation succeeds or fails. You can change this behavior +by using #VMA_ALLOCATION_CREATE_WITHIN_BUDGET_BIT flag. With it, the allocation is +not made if it would exceed the budget or if the budget is already exceeded. +VMA then tries to make the allocation from the next eligible Vulkan memory type. +If all of them fail, the call then fails with `VK_ERROR_OUT_OF_DEVICE_MEMORY`. +Example usage pattern may be to pass the #VMA_ALLOCATION_CREATE_WITHIN_BUDGET_BIT flag +when creating resources that are not essential for the application (e.g. the texture +of a specific object) and not to pass it when creating critically important resources +(e.g. render targets). + +On AMD graphics cards there is a custom vendor extension available: VK_AMD_memory_overallocation_behavior +that allows to control the behavior of the Vulkan implementation in out-of-memory cases - +whether it should fail with an error code or still allow the allocation. +Usage of this extension involves only passing extra structure on Vulkan device creation, +so it is out of scope of this library. + +Finally, you can also use #VMA_ALLOCATION_CREATE_NEVER_ALLOCATE_BIT flag to make sure +a new allocation is created only when it fits inside one of the existing memory blocks. +If it would require to allocate a new block, if fails instead with `VK_ERROR_OUT_OF_DEVICE_MEMORY`. +This also ensures that the function call is very fast because it never goes to Vulkan +to obtain a new block. + +\note Creating \ref custom_memory_pools with VmaPoolCreateInfo::minBlockCount +set to more than 0 will currently try to allocate memory blocks without checking whether they +fit within budget. + + +\page resource_aliasing Resource aliasing (overlap) + +New explicit graphics APIs (Vulkan and Direct3D 12), thanks to manual memory +management, give an opportunity to alias (overlap) multiple resources in the +same region of memory - a feature not available in the old APIs (Direct3D 11, OpenGL). +It can be useful to save video memory, but it must be used with caution. + +For example, if you know the flow of your whole render frame in advance, you +are going to use some intermediate textures or buffers only during a small range of render passes, +and you know these ranges don't overlap in time, you can bind these resources to +the same place in memory, even if they have completely different parameters (width, height, format etc.). + +![Resource aliasing (overlap)](../gfx/Aliasing.png) + +Such scenario is possible using VMA, but you need to create your images manually. +Then you need to calculate parameters of an allocation to be made using formula: + +- allocation size = max(size of each image) +- allocation alignment = max(alignment of each image) +- allocation memoryTypeBits = bitwise AND(memoryTypeBits of each image) + +Following example shows two different images bound to the same place in memory, +allocated to fit largest of them. + +\code +// A 512x512 texture to be sampled. +VkImageCreateInfo img1CreateInfo = { VK_STRUCTURE_TYPE_IMAGE_CREATE_INFO };

"Memory Aliasing" of Vulkan specification or `VK_IMAGE_CREATE_ALIAS_BIT` flag. +- You can create more complex layout where different images and buffers are bound +at different offsets inside one large allocation. For example, one can imagine +a big texture used in some render passes, aliasing with a set of many small buffers +used between in some further passes. To bind a resource at non-zero offset in an allocation, +use vmaBindBufferMemory2() / vmaBindImageMemory2(). +- Before allocating memory for the resources you want to alias, check `memoryTypeBits` +returned in memory requirements of each resource to make sure the bits overlap. +Some GPUs may expose multiple memory types suitable e.g. only for buffers or +images with `COLOR_ATTACHMENT` usage, so the sets of memory types supported by your +resources may be disjoint. Aliasing them is not possible in that case. + + +\page custom_memory_pools Custom memory pools + +A memory pool contains a number of `VkDeviceMemory` blocks. +The library automatically creates and manages default pool for each memory type available on the device. +Default memory pool automatically grows in size. +Size of allocated blocks is also variable and managed automatically. +You are using default pools whenever you leave VmaAllocationCreateInfo::pool = null. + +You can create custom pool and allocate memory out of it. +It can be useful if you want to: + +- Keep certain kind of allocations separate from others. +- Enforce particular, fixed size of Vulkan memory blocks. +- Limit maximum amount of Vulkan memory allocated for that pool. +- Reserve minimum or fixed amount of Vulkan memory always preallocated for that pool. +- Use extra parameters for a set of your allocations that are available in #VmaPoolCreateInfo but not in + #VmaAllocationCreateInfo - e.g., custom minimum alignment, custom `pNext` chain. +- Perform defragmentation on a specific subset of your allocations. + +To use custom memory pools: + +-# Fill VmaPoolCreateInfo structure. +-# Call vmaCreatePool() to obtain #VmaPool handle. +-# When making an allocation, set VmaAllocationCreateInfo::pool to this handle. + You don't need to specify any other parameters of this structure, like `usage`. + +Example: + +\code +// Find memoryTypeIndex for the pool. +VkBufferCreateInfo sampleBufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO }; +sampleBufCreateInfo.size = 0x10000; // Doesn't matter. +sampleBufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT; + +VmaAllocationCreateInfo sampleAllocCreateInfo = {}; +sampleAllocCreateInfo.usage = VMA_MEMORY_USAGE_AUTO; + +uint32_t memTypeIndex; +VkResult res = vmaFindMemoryTypeIndexForBufferInfo(allocator, + &sampleBufCreateInfo, &sampleAllocCreateInfo, &memTypeIndex); +// Check res... + +// Create a pool that can have at most 2 blocks, 128 MiB each. +VmaPoolCreateInfo poolCreateInfo = {}; +poolCreateInfo.memoryTypeIndex = memTypeIndex; +poolCreateInfo.blockSize = 128ULL * 1024 * 1024; +poolCreateInfo.maxBlockCount = 2; + +VmaPool pool; +res = vmaCreatePool(allocator, &poolCreateInfo, &pool); +// Check res... + +// Allocate a buffer out of it. +VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO }; +bufCreateInfo.size = 1024; +bufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT; + +VmaAllocationCreateInfo allocCreateInfo = {}; +allocCreateInfo.pool = pool; + +VkBuffer buf; +VmaAllocation alloc; +res = vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, nullptr); +// Check res... +\endcode + +You have to free all allocations made from this pool before destroying it. + +\code +vmaDestroyBuffer(allocator, buf, alloc); +vmaDestroyPool(allocator, pool); +\endcode + +New versions of this library support creating dedicated allocations in custom pools. +It is supported only when VmaPoolCreateInfo::blockSize = 0. +To use this feature, set VmaAllocationCreateInfo::pool to the pointer to your custom pool and +VmaAllocationCreateInfo::flags to #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT. + + +\section custom_memory_pools_MemTypeIndex Choosing memory type index + +When creating a pool, you must explicitly specify memory type index. +To find the one suitable for your buffers or images, you can use helper functions +vmaFindMemoryTypeIndexForBufferInfo(), vmaFindMemoryTypeIndexForImageInfo(). +You need to provide structures with example parameters of buffers or images +that you are going to create in that pool. + +\code +VkBufferCreateInfo exampleBufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO }; +exampleBufCreateInfo.size = 1024; // Doesn't matter +exampleBufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT; + +VmaAllocationCreateInfo allocCreateInfo = {}; +allocCreateInfo.usage = VMA_MEMORY_USAGE_AUTO; + +uint32_t memTypeIndex; +vmaFindMemoryTypeIndexForBufferInfo(allocator, &exampleBufCreateInfo, &allocCreateInfo, &memTypeIndex); + +VmaPoolCreateInfo poolCreateInfo = {}; +poolCreateInfo.memoryTypeIndex = memTypeIndex; +// ... +\endcode + +When creating buffers/images allocated in that pool, provide following parameters: + +- `VkBufferCreateInfo`: Prefer to pass same parameters as above. + Otherwise you risk creating resources in a memory type that is not suitable for them, which may result in undefined behavior. + Using different `VK_BUFFER_USAGE_` flags may work, but you shouldn't create images in a pool intended for buffers + or the other way around. +- VmaAllocationCreateInfo: You don't need to pass same parameters.

This way you can allocate and free objects in any order. + +![Default allocation algorithm](../gfx/Linear_allocator_1_algo_default.png) + +Sometimes there is a need to use simpler, linear allocation algorithm. You can +create custom pool that uses such algorithm by adding flag +#VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT to VmaPoolCreateInfo::flags while creating +#VmaPool object. Then an alternative metadata management is used. It always +creates new allocations after last one and doesn't reuse free regions after +allocations freed in the middle. It results in better allocation performance and +less memory consumed by metadata. + +![Linear allocation algorithm](../gfx/Linear_allocator_2_algo_linear.png) + +With this one flag, you can create a custom pool that can be used in many ways: +free-at-once, stack, double stack, and ring buffer.

However, when you release all the allocation and +the pool becomes empty, allocation starts from the beginning again.

Get new #VmaVirtualBlock object. + +Example: + +\code +VmaVirtualBlockCreateInfo blockCreateInfo = {}; +blockCreateInfo.size = 1048576; // 1 MB + +VmaVirtualBlock block; +VkResult res = vmaCreateVirtualBlock(&blockCreateInfo, &block); +\endcode + +\section virtual_allocator_making_virtual_allocations Making virtual allocations + +#VmaVirtualBlock object contains internal data structure that keeps track of free and occupied regions +using the same code as the main Vulkan memory allocator. +Similarly to #VmaAllocation for standard GPU allocations, there is #VmaVirtualAllocation type +that represents an opaque handle to an allocation within the virtual block. + +In order to make such allocation: + +-# Fill in #VmaVirtualAllocationCreateInfo structure. +-# Call vmaVirtualAllocate(). Get new #VmaVirtualAllocation object that represents the allocation. + You can also receive `VkDeviceSize offset` that was assigned to the allocation. + +Example: + +\code +VmaVirtualAllocationCreateInfo allocCreateInfo = {}; +allocCreateInfo.size = 4096; // 4 KB + +VmaVirtualAllocation alloc; +VkDeviceSize offset; +res = vmaVirtualAllocate(block, &allocCreateInfo, &alloc, &offset); +if(res == VK_SUCCESS) +{ + // Use the 4 KB of your memory starting at offset. +} +else +{ + // Allocation failed - no space for it could be found. Handle this error! +} +\endcode + +\section virtual_allocator_deallocation Deallocation + +When no longer needed, an allocation can be freed by calling vmaVirtualFree(). +You can only pass to this function an allocation that was previously returned by vmaVirtualAllocate() +called for the same #VmaVirtualBlock. + +When whole block is no longer needed, the block object can be released by calling vmaDestroyVirtualBlock(). +All allocations must be freed before the block is destroyed, which is checked internally by an assert. +However, if you don't want to call vmaVirtualFree() for each allocation, you can use vmaClearVirtualBlock() to free them all at once - +a feature not available in normal Vulkan memory allocator. Example: + +\code +vmaVirtualFree(block, alloc); +vmaDestroyVirtualBlock(block); +\endcode + +\section virtual_allocator_allocation_parameters Allocation parameters + +You can attach a custom pointer to each allocation by using vmaSetVirtualAllocationUserData(). +Its default value is null. +It can be used to store any data that needs to be associated with that allocation - e.g. an index, a handle, or a pointer to some +larger data structure containing more information. Example: + +\code +struct CustomAllocData +{ + std::string m_AllocName; +}; +CustomAllocData* allocData = new CustomAllocData(); +allocData->m_AllocName = "My allocation 1"; +vmaSetVirtualAllocationUserData(block, alloc, allocData); +\endcode + +The pointer can later be fetched, along with allocation offset and size, by passing the allocation handle to function +vmaGetVirtualAllocationInfo() and inspecting returned structure #VmaVirtualAllocationInfo. +If you allocated a new object to be used as the custom pointer, don't forget to delete that object before freeing the allocation! +Example: + +\code +VmaVirtualAllocationInfo allocInfo; +vmaGetVirtualAllocationInfo(block, alloc, &allocInfo); +delete (CustomAllocData*)allocInfo.pUserData; + +vmaVirtualFree(block, alloc); +\endcode + +\section virtual_allocator_alignment_and_units Alignment and units + +It feels natural to express sizes and offsets in bytes. +If an offset of an allocation needs to be aligned to a multiply of some number (e.g. 4 bytes), you can fill optional member +VmaVirtualAllocationCreateInfo::alignment to request it. Example: + +\code +VmaVirtualAllocationCreateInfo allocCreateInfo = {}; +allocCreateInfo.size = 4096; // 4 KB +allocCreateInfo.alignment = 4; // Returned offset must be a multiply of 4 B + +VmaVirtualAllocation alloc; +res = vmaVirtualAllocate(block, &allocCreateInfo, &alloc, nullptr); +\endcode + +Alignments of different allocations made from one block may vary. +However, if all alignments and sizes are always multiply of some size e.g. 4 B or `sizeof(MyDataStruct)`, +you can express all sizes, alignments, and offsets in multiples of that size instead of individual bytes. +It might be more convenient, but you need to make sure to use this new unit consistently in all the places: + +- VmaVirtualBlockCreateInfo::size +- VmaVirtualAllocationCreateInfo::size and VmaVirtualAllocationCreateInfo::alignment +- Using offset returned by vmaVirtualAllocate() or in VmaVirtualAllocationInfo::offset + +\section virtual_allocator_statistics Statistics + +You can obtain statistics of a virtual block using vmaGetVirtualBlockStatistics() +(to get brief statistics that are fast to calculate) +or vmaCalculateVirtualBlockStatistics() (to get more detailed statistics, slower to calculate). +The functions fill structures #VmaStatistics, #VmaDetailedStatistics respectively - same as used by the normal Vulkan memory allocator. +Example: + +\code +VmaStatistics stats; +vmaGetVirtualBlockStatistics(block, &stats); +printf("My virtual block has %llu bytes used by %u virtual allocations\n", + stats.allocationBytes, stats.allocationCount); +\endcode + +You can also request a full list of allocations and free regions as a string in JSON format by calling +vmaBuildVirtualBlockStatsString(). +Returned string must be later freed using vmaFreeVirtualBlockStatsString(). +The format of this string differs from the one returned by the main Vulkan allocator, but it is similar. + +\section virtual_allocator_additional_considerations Additional considerations + +The "virtual allocator" functionality is implemented on a level of individual memory blocks. +Keeping track of a whole collection of blocks, allocating new ones when out of free space, +deleting empty ones, and deciding which one to try first for a new allocation must be implemented by the user. + +Alternative allocation algorithms are supported, just like in custom pools of the real GPU memory. +See enum #VmaVirtualBlockCreateFlagBits to learn how to specify them (e.g. #VMA_VIRTUAL_BLOCK_CREATE_LINEAR_ALGORITHM_BIT). +You can find their description in chapter \ref custom_memory_pools. +Allocation strategies are also supported. +See enum #VmaVirtualAllocationCreateFlagBits to learn how to specify them (e.g. #VMA_VIRTUAL_ALLOCATION_CREATE_STRATEGY_MIN_TIME_BIT). + +Following features are supported only by the allocator of the real GPU memory and not by virtual allocations: +buffer-image granularity, `VMA_DEBUG_MARGIN`, `VMA_MIN_ALIGNMENT`. + + +\page debugging_memory_usage Debugging incorrect memory usage + +If you suspect a bug with memory usage, like usage of uninitialized memory or +memory being overwritten out of bounds of an allocation, +you can use debug features of this library to verify this. + +\section debugging_memory_usage_initialization Memory initialization + +If you experience a bug with incorrect and nondeterministic data in your program and you suspect uninitialized memory to be used, +you can enable automatic memory initialization to verify this. +To do it, define macro `VMA_DEBUG_INITIALIZE_ALLOCATIONS` to 1. + +\code +#define VMA_DEBUG_INITIALIZE_ALLOCATIONS 1 +#include "vk_mem_alloc.h" +\endcode + +It makes memory of new allocations initialized to bit pattern `0xDCDCDCDC`. +Before an allocation is destroyed, its memory is filled with bit pattern `0xEFEFEFEF`. +Memory is automatically mapped and unmapped if necessary. + +If you find these values while debugging your program, good chances are that you incorrectly +read Vulkan memory that is allocated but not initialized, or already freed, respectively. + +Memory initialization works only with memory types that are `HOST_VISIBLE` and with allocations that can be mapped. +It works also with dedicated allocations. + +\section debugging_memory_usage_margins Margins + +By default, allocations are laid out in memory blocks next to each other if possible +(considering required alignment, `bufferImageGranularity`, and `nonCoherentAtomSize`). + +![Allocations without margin](../gfx/Margins_1.png) + +Define macro `VMA_DEBUG_MARGIN` to some non-zero value (e.g. 16) to enforce specified +number of bytes as a margin after every allocation. + +\code +#define VMA_DEBUG_MARGIN 16 +#include "vk_mem_alloc.h" +\endcode + +![Allocations with margin](../gfx/Margins_2.png) + +If your bug goes away after enabling margins, it means it may be caused by memory +being overwritten outside of allocation boundaries. It is not 100% certain though. +Change in application behavior may also be caused by different order and distribution +of allocations across memory blocks after margins are applied. + +Margins work with all types of memory. + +Margin is applied only to allocations made out of memory blocks and not to dedicated +allocations, which have their own memory block of specific size. +It is thus not applied to allocations made using #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT flag +or those automatically decided to put into dedicated allocations, e.g. due to its +large size or recommended by VK_KHR_dedicated_allocation extension. + +Margins appear in [JSON dump](@ref statistics_json_dump) as part of free space. + +Note that enabling margins increases memory usage and fragmentation. + +Margins do not apply to \ref virtual_allocator. + +\section debugging_memory_usage_corruption_detection Corruption detection + +You can additionally define macro `VMA_DEBUG_DETECT_CORRUPTION` to 1 to enable validation +of contents of the margins. + +\code +#define VMA_DEBUG_MARGIN 16 +#define VMA_DEBUG_DETECT_CORRUPTION 1 +#include "vk_mem_alloc.h" +\endcode + +When this feature is enabled, number of bytes specified as `VMA_DEBUG_MARGIN` +(it must be multiply of 4) after every allocation is filled with a magic number. +This idea is also know as "canary". +Memory is automatically mapped and unmapped if necessary. + +This number is validated automatically when the allocation is destroyed. +If it is not equal to the expected value, `VMA_ASSERT()` is executed. +It clearly means that either CPU or GPU overwritten the memory outside of boundaries of the allocation, +which indicates a serious bug. + +You can also explicitly request checking margins of all allocations in all memory blocks +that belong to specified memory types by using function vmaCheckCorruption(), +or in memory blocks that belong to specified custom pool, by using function +vmaCheckPoolCorruption(). + +Margin validation (corruption detection) works only for memory types that are +`HOST_VISIBLE` and `HOST_COHERENT`. + + +\section debugging_memory_usage_leak_detection Leak detection features + +At allocation and allocator destruction time VMA checks for unfreed and unmapped blocks using +`VMA_ASSERT_LEAK()`. This macro defaults to an assertion, triggering a typically fatal error in Debug +builds, and doing nothing in Release builds. You can provide your own definition of `VMA_ASSERT_LEAK()` +to change this behavior. + +At memory block destruction time VMA lists out all unfreed allocations using the `VMA_LEAK_LOG_FORMAT()` +macro, which defaults to `VMA_DEBUG_LOG_FORMAT`, which in turn defaults to a no-op. +If you're having trouble with leaks - for example, the aforementioned assertion triggers, but you don't +quite know \em why -, overriding this macro to print out the the leaking blocks, combined with assigning +individual names to allocations using vmaSetAllocationName(), can greatly aid in fixing them. + +\page other_api_interop Interop with other graphics APIs + +VMA provides some features that help with interoperability with other graphics APIs, e.g. OpenGL. + +\section opengl_interop_exporting_memory Exporting memory + +If you want to attach `VkExportMemoryAllocateInfoKHR` or other structure to `pNext` chain of memory allocations made by the library: + +You can create \ref custom_memory_pools for such allocations. +Define and fill in your `VkExportMemoryAllocateInfoKHR` structure and attach it to VmaPoolCreateInfo::pMemoryAllocateNext +while creating the custom pool. +Please note that the structure must remain alive and unchanged for the whole lifetime of the #VmaPool, +not only while creating it, as no copy of the structure is made, +but its original pointer is used for each allocation instead. + +If you want to export all memory allocated by VMA from certain memory types, +also dedicated allocations or other allocations made from default pools, +an alternative solution is to fill in VmaAllocatorCreateInfo::pTypeExternalMemoryHandleTypes. +It should point to an array with `VkExternalMemoryHandleTypeFlagsKHR` to be automatically passed by the library +through `VkExportMemoryAllocateInfoKHR` on each allocation made from a specific memory type. +Please note that new versions of the library also support dedicated allocations created in custom pools. + +You should not mix these two methods in a way that allows to apply both to the same memory type. +Otherwise, `VkExportMemoryAllocateInfoKHR` structure would be attached twice to the `pNext` chain of `VkMemoryAllocateInfo`. + + +\section opengl_interop_custom_alignment Custom alignment + +Buffers or images exported to a different API like OpenGL may require a different alignment, +higher than the one used by the library automatically, queried from functions like `vkGetBufferMemoryRequirements`. +To impose such alignment: + +You can create \ref custom_memory_pools for such allocations. +Set VmaPoolCreateInfo::minAllocationAlignment member to the minimum alignment required for each allocation +to be made out of this pool. +The alignment actually used will be the maximum of this member and the alignment returned for the specific buffer or image +from a function like `vkGetBufferMemoryRequirements`, which is called by VMA automatically. + +If you want to create a buffer with a specific minimum alignment out of default pools, +use special function vmaCreateBufferWithAlignment(), which takes additional parameter `minAlignment`. + +Note the problem of alignment affects only resources placed inside bigger `VkDeviceMemory` blocks and not dedicated +allocations, as these, by definition, always have alignment = 0 because the resource is bound to the beginning of its dedicated block. +You can ensure that an allocation is created as dedicated by using #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT. +Contrary to Direct3D 12, Vulkan doesn't have a concept of alignment of the entire memory block passed on its allocation. + +\section opengl_interop_extended_allocation_information Extended allocation information + +If you want to rely on VMA to allocate your buffers and images inside larger memory blocks, +but you need to know the size of the entire block and whether the allocation was made +with its own dedicated memory, use function vmaGetAllocationInfo2() to retrieve +extended allocation information in structure #VmaAllocationInfo2. + + + +\page usage_patterns Recommended usage patterns + +Vulkan gives great flexibility in memory allocation. +This chapter shows the most common patterns. + +See also slides from talk: +[Sawicki, Adam.

Then, it is likely the best choice for such type of resource. +-# Systems with a discrete graphics card and separate video memory may or may not expose + a memory type that is both `HOST_VISIBLE` and `DEVICE_LOCAL`, also known as Base Address Register (BAR). + If they do, it represents a piece of VRAM (or entire VRAM, if ReBAR is enabled in the motherboard BIOS) + that is available to CPU for mapping. + - Writes performed by the host to that memory go through PCI Express bus. + The performance of these writes may be limited, but it may be fine, especially on PCIe 4.0, + as long as rules of using uncached and write-combined memory are followed - only sequential writes and no reads. +-# Finally, you may need or prefer to create a separate copy of the resource in `DEVICE_LOCAL` memory, + a separate "staging" copy in `HOST_VISIBLE` memory and perform an explicit transfer command between them. + +Thankfully, VMA offers an aid to create and use such resources in the the way optimal +for the current Vulkan device. To help the library make the best choice, +use flag #VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT together with +#VMA_ALLOCATION_CREATE_HOST_ACCESS_ALLOW_TRANSFER_INSTEAD_BIT. +It will then prefer a memory type that is both `DEVICE_LOCAL` and `HOST_VISIBLE` (integrated memory or BAR), +but if no such memory type is available or allocation from it fails +(PC graphics cards have only 256 MB of BAR by default, unless ReBAR is supported and enabled in BIOS), +it will fall back to `DEVICE_LOCAL` memory for fast GPU access. +It is then up to you to detect that the allocation ended up in a memory type that is not `HOST_VISIBLE`, +so you need to create another "staging" allocation and perform explicit transfers. + +\code +VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };

The kernel funnels src0/src1 through cublasSgemm, which is f32-only. The original predicate src0_is_quantized = (type != F32 && type != F16) let F16 tensors pass straight through, reinterpreting their bytes as f32: this corrupts the values and halves the leading dimension (ldb = nb11/sizeof(float) = ne10/2). rocBLAS rejects the bad ld with CUBLAS_STATUS_INVALID_VALUE; NVIDIA's cuBLAS is laxer but computes garbage. Renaming to src0_needs_f32 = (type != F32) forces the dequantize/copy path for F16 as well, giving ne-based f32 strides. OUT_PROD is the MUL_MAT backward op driven by the branch's LoRA/training path, where F16 base weights routinely reach this kernel; on AMD/RADV (rocBLAS) that previously aborted the finetune. --- ggml/src/ggml-cuda/ggml-cuda.cu | 3 +- ggml/src/ggml-cuda/out-prod.cu | 109 ++++++++++++++++++++++++++++---- 2 files changed, 99 insertions(+), 13 deletions(-) diff --git a/ggml/src/ggml-cuda/ggml-cuda.cu b/ggml/src/ggml-cuda/ggml-cuda.cu index f3fb32452d2c..1c7720b5cc3e 100644 --- a/ggml/src/ggml-cuda/ggml-cuda.cu +++ b/ggml/src/ggml-cuda/ggml-cuda.cu @@ -5202,7 +5202,8 @@ static bool ggml_backend_cuda_device_supports_op(ggml_backend_dev_t dev, const g } } break; case GGML_OP_OUT_PROD: - return op->type == GGML_TYPE_F32 && op->src[0]->type == GGML_TYPE_F32 && op->src[1]->type == GGML_TYPE_F32; + // return op->type == GGML_TYPE_F32 && op->src[0]->type == GGML_TYPE_F32 && op->src[1]->type == GGML_TYPE_F32; + return op->type == GGML_TYPE_F32; case GGML_OP_GET_ROWS: { switch (op->src[0]->type) { diff --git a/ggml/src/ggml-cuda/out-prod.cu b/ggml/src/ggml-cuda/out-prod.cu index 46b9f3a67ee5..eb0295015cf1 100644 --- a/ggml/src/ggml-cuda/out-prod.cu +++ b/ggml/src/ggml-cuda/out-prod.cu @@ -1,4 +1,5 @@ #include "out-prod.cuh" +#include "convert.cuh" #include @@ -30,10 +31,66 @@ void ggml_cuda_out_prod(ggml_backend_cuda_context & ctx, ggml_tensor * dst) { GGML_TENSOR_BINARY_OP_LOCALS - GGML_ASSERT(src0->type == GGML_TYPE_F32); - GGML_ASSERT(src1->type == GGML_TYPE_F32); + // Anything that is not already f32 must be converted to a contiguous f32 buffer before the + // cublasSgemm below: the GEMM is f32-only. f16 is included here on purpose — reinterpreting + // f16 bytes as f32 both corrupts the values and halves the leading dimension (e.g. + // ldb = nb11/sizeof(float) = ne10/2), which rocBLAS rejects with CUBLAS_STATUS_INVALID_VALUE + // (NVIDIA's cuBLAS is laxer but still computes garbage).

Fix geglu_back implementation - Fix CPU implementation: now correctly computes gelu_backward(gate, grad) instead of splitting computation across two halves - Update Vulkan shader to match corrected implementation with proper gelu_backward - Add a test for geglu_back op The previous implementation incorrectly assumed geglu_back operated on concatenated tensors and split them.

Needed qvac-b9840 because OUT_PROD is the MUL_MAT backward op exercised by this branch's LoRA/training path with F16 weights; on rocBLAS (AMD/RADV) reinterpreting F16 as f32 halves the leading dimension and is rejected with CUBLAS_STATUS_INVALID_VALUE (NVIDIA silently computes garbage). --- examples/training/finetune.cpp | 2 +- ggml/src/ggml-cuda/ggml-cuda.cu | 1 - ggml/src/ggml-cuda/out-prod.cu | 54 ++++------------ ggml/src/ggml-vulkan/ggml-vulkan.cpp | 63 +++++++++++++++++- .../ggml-vulkan/vulkan-shaders/out_prod.comp | 56 ++++++++++++++++ .../vulkan-shaders/out_prod_q4_0.comp | 57 +++++++++++++++++ .../vulkan-shaders/out_prod_q8_0.comp | 64 +++++++++++++++++++ .../vulkan-shaders/vulkan-shaders-gen.cpp | 5 ++ src/llama-lora-training.cpp | 2 +- 9 files changed, 260 insertions(+), 44 deletions(-) create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/out_prod.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/out_prod_q4_0.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/out_prod_q8_0.comp diff --git a/examples/training/finetune.cpp b/examples/training/finetune.cpp index d1b6a5dfae81..9addab552321 100644 --- a/examples/training/finetune.cpp +++ b/examples/training/finetune.cpp @@ -171,4 +171,4 @@ int main(int argc, char ** argv) { llama_backend_free(); return 0; -} \ No newline at end of file +} diff --git a/ggml/src/ggml-cuda/ggml-cuda.cu b/ggml/src/ggml-cuda/ggml-cuda.cu index 1c7720b5cc3e..716c43e3ed4d 100644 --- a/ggml/src/ggml-cuda/ggml-cuda.cu +++ b/ggml/src/ggml-cuda/ggml-cuda.cu @@ -5202,7 +5202,6 @@ static bool ggml_backend_cuda_device_supports_op(ggml_backend_dev_t dev, const g } } break; case GGML_OP_OUT_PROD: - // return op->type == GGML_TYPE_F32 && op->src[0]->type == GGML_TYPE_F32 && op->src[1]->type == GGML_TYPE_F32; return op->type == GGML_TYPE_F32; case GGML_OP_GET_ROWS: { diff --git a/ggml/src/ggml-cuda/out-prod.cu b/ggml/src/ggml-cuda/out-prod.cu index eb0295015cf1..506d342c66c1 100644 --- a/ggml/src/ggml-cuda/out-prod.cu +++ b/ggml/src/ggml-cuda/out-prod.cu @@ -39,27 +39,23 @@ void ggml_cuda_out_prod(ggml_backend_cuda_context & ctx, ggml_tensor * dst) { const bool src0_needs_f32 = (src0->type != GGML_TYPE_F32); const bool src1_needs_f32 = (src1->type != GGML_TYPE_F32); - // if (src0_is_quantized || src1_is_quantized) { - // printf("DEBUG: OUT_PROD with quantized tensors - src0_quantized=%d, src1_quantized=%d\n", - // src0_is_quantized, src1_is_quantized); - // fflush(stdout); - // } - - // GGML_ASSERT(src0->type == GGML_TYPE_F32); - // GGML_ASSERT(src1->type == GGML_TYPE_F32); - GGML_ASSERT(dst->type == GGML_TYPE_F32); + cudaStream_t stream = ctx.stream(); + ggml_cuda_pool & pool = ctx.pool(); + // temp buffers float * src0_f32 = nullptr; float * src1_f32 = nullptr; bool allocated_src0 = false; bool allocated_src1 = false; - cudaStream_t stream = ctx.stream(); + ggml_cuda_pool_alloc src0_alloc(pool); + ggml_cuda_pool_alloc src1_alloc(pool); - if (src0_is_quantized) { - const size_t src0_size = ggml_nelements(src0) * sizeof(float); - CUDA_CHECK(cudaMallocAsync(&src0_f32, src0_size, stream)); + if (src0_needs_f32) { + const size_t src0_size = ggml_nelements(src0); + src0_alloc.alloc(src0_size); + src0_f32 = src0_alloc.ptr; allocated_src0 = true; // Dequantize @@ -67,23 +63,22 @@ void ggml_cuda_out_prod(ggml_backend_cuda_context & ctx, ggml_tensor * dst) { if (dequantize_fn) { dequantize_fn(src0->data, src0_f32, ggml_nelements(src0), stream); } else { - CUDA_CHECK(cudaFreeAsync(src0_f32, stream)); GGML_ABORT("Unsupported quant type for src0"); } } else { src0_f32 = (float *) src0->data; } - if (src1_is_quantized) { - const size_t src1_size = ggml_nelements(src1) * sizeof(float); - CUDA_CHECK(cudaMallocAsync(&src1_f32, src1_size, stream)); + if (src1_needs_f32) { + const size_t src1_size = ggml_nelements(src1); + src1_alloc.alloc(src1_size); + src1_f32 = src1_alloc.ptr; allocated_src1 = true; auto dequantize_fn = ggml_get_to_fp32_cuda(src1->type); if (dequantize_fn) { - dequantize_fn(src1->data, src1_f32, ggml_nelements(src0), stream); + dequantize_fn(src1->data, src1_f32, ggml_nelements(src1), stream); } else { - CUDA_CHECK(cudaFreeAsync(src1_f32, stream)); GGML_ABORT("Unsupported quant type for src1"); } } else { @@ -101,9 +96,6 @@ void ggml_cuda_out_prod(ggml_backend_cuda_context & ctx, ggml_tensor * dst) { GGML_ASSERT(ne2 == src1->ne[2]); GGML_ASSERT(ne3 == src1->ne[3]); - // const float * src0_d = (const float *) src0->data; - // const float * src1_d = (const float *) src1->data; - // Use dequantized data const float * src0_d = src0_f32; const float * src1_d = src1_f32; @@ -116,28 +108,21 @@ void ggml_cuda_out_prod(ggml_backend_cuda_context & ctx, ggml_tensor * dst) { CUBLAS_CHECK(cublasSetStream(handle, stream)); - // const int64_t lda = nb01 / sizeof(float); const int64_t lda = allocated_src0 ? ne00 : (nb01 / sizeof(float)); const int64_t ldc = nb1 / sizeof(float); const bool src1_T = ggml_is_transposed(src1); const cublasOperation_t src1_cublas_op = src1_T ?

However, opt_epoch used `resume_from_batch > 0` to distinguish resume from non-resume, which means resume_from_batch=0 (a valid value meaning "batch 0 was the last completed, start from batch 1") was silently treated as no-resume, causing the entire epoch to replay from the start. This affects any caller that pauses training after the first batch of an epoch (globalStep=1, or any globalStep that is a multiple of stepsPerEpoch + 1), since the computed resume batch offset modulo stepsPerEpoch is 0. Fix: change `> 0` to `>= 0` in both the idata start position and the idata_in_loop calculation, so that -1 remains the only sentinel for "no resume."

Cache compiled OpenCL programs to disk using clCreateProgramWithBinary on subsequent runs, keyed by SHA-256 of source + device + driver + compile opts + GGML version/commit. Cache is automatically invalidated when the library version changes (GGML_OPENCL_CACHE_VERSION is set from GGML_VERSION + GGML_BUILD_COMMIT at compile time). Env controls: GGML_OPENCL_KERNEL_CACHE=0 disable cache at runtime GGML_OPENCL_CACHE_DIR set cache directory (no default; caller must set explicitly via env) Also clarifies the clGetPlatformIDs error message. Retrieves device name and driver name from OpenCL in favor of changing the build_program_from_source function signature. Allows keeping upstream build_program_from_source and makes patch more portable.

The only functional behaviour change is the Vulkan SSM_CONV dispatch fix — the rest restores or shims qvac-side surfaces the rebase dropped. ggml-vulkan: - SSM_CONV binds four buffers, with a dummy bias buffer (src0) at the bias slot, to match the fused BIAS+SILU shader's 4-binding layout. Previously the dispatch bound 3 buffers, leaving dst (binding 3) unbound, so the conv output was never written. (APPLY_BIAS/SILU stay false.) llama-model: - virtual load_*/build_arch_* methods get no-op defaults so the monolithic switch(arch) path keeps compiling against b9341's polymorphic interface without splitting every arch into a subclass yet. - load_arch() and the flat attention-bias fields (bq/bk/bv/bo/bqkv) are restored. - build_graph() aborts if an arch has no polymorphic build_arch_graph(). llama-io / llama-context: - adopt read(size)/read_to() and const write_tensor (b9341 zero-copy read + read-only IO); add a read(dst) shim and a base read_tensor so kv-cache/memory serialization callers need no mass rewrite (the host/device readers still override read_tensor, so it stays virtual). - declare llama_memory_breakdown_print; default get_opt_pars to ggml_opt_get_default_optimizer_params. common / include/llama.h: - restore qvac surfaces dropped in b9341: llama_params_fit (+ status enum), build-info macros/externs, the llama-common CMake alias, and generation_prompt in the chat auto-parser. mtmd/clip.h: - re-expose clip_get_mem_usage (behind __cplusplus) and declare clip_has_whisper_encoder for common/fit.cpp's memory heuristics; guard the include behind __cplusplus. tools/cli: - string_starts_with takes a string literal, not a char (build fix). tests: - test-backend-ops.cpp: add trailing newline only (no functional change). --- common/CMakeLists.txt | 9 ++++++- common/chat-auto-parser.h | 1 + common/common.h | 19 ++++++++++++--- include/llama.h | 21 +++++++++++++++++ src/llama-context.cpp | 42 ++++++++++++++++++++------------- src/llama-context.h | 4 ++++ src/llama-io.cpp | 13 +++++++++-- src/llama-io.h | 20 +++++++++++++--- src/llama-model.cpp | 8 +++++++ src/llama-model.h | 48 +++++++++++++++++++++++++++----------- tests/test-backend-ops.cpp | 2 +- tools/cli/cli.cpp | 6 ++--- tools/mtmd/clip.h | 9 ++++++- 13 files changed, 159 insertions(+), 43 deletions(-) diff --git a/common/CMakeLists.txt b/common/CMakeLists.txt index 274a7d31d87e..4de976587a8c 100644 --- a/common/CMakeLists.txt +++ b/common/CMakeLists.txt @@ -65,7 +65,7 @@ set(${TARGET}_HEADERS console.h debug.h download.h - fit.h + fit.h # qvac: declarations for the fit helpers (memory_breakdown_print, get_device_memory_data) hf-cache.h http.h imatrix-loader.h @@ -192,6 +192,13 @@ target_include_directories( target_compile_features (${TARGET} PUBLIC cxx_std_17) target_link_libraries (${TARGET} PRIVATE ${LLAMA_COMMON_EXTRA_LIBS} PUBLIC llama Threads::Threads) +# qvac: rebase onto upstream b9341 renamed the common target to `llama-common`. +# Keep both names addressable so qvac-side CMakeLists (target `common`) and +# upstream/example/tool CMakeLists (target `llama-common`) both link. +if (NOT TARGET llama-common) + add_library(llama-common ALIAS ${TARGET}) +endif() + # # copy the license files diff --git a/common/chat-auto-parser.h b/common/chat-auto-parser.h index 9e8113f24421..c5cb979165c7 100644 --- a/common/chat-auto-parser.h +++ b/common/chat-auto-parser.h @@ -61,6 +61,7 @@ struct generation_params { bool stream = true;

On Mali-G715, this fused dispatch corrupts subsequent GPU state — the next attention op's mul_mat_q_f16 descriptor-pool submit fence-waits and gets vk::Device::getFenceStatus: ErrorDeviceLost. Pre-b9341 source (f686a1324) on the same Mali-G715 hardware ran the un-fused two-op sequence (ROPE→compute buffer, SET_ROWS→cache) cleanly at ~19.6 t/s with bitnet TQ2_0 fully on the GPU. The compiled SPIR-V binaries for matmul/rope/set_rows shaders are md5-byte-identical between the two builds, so the regression is purely the fusion pattern, not the shader code. Gate the fusion off for Mali/Adreno KHR_coopmat1 (VK_VENDOR_ID_ARM or VK_VENDOR_ID_QUALCOMM with coopmat_support and !coopmat2). Desktop GPUs (NVIDIA/AMD/Intel) and coopmat2 hardware keep the optimization. The 5-op RMS_NORM+MUL+ROPE+VIEW+SET_ROWS fusion also routes through this guard via its ggml_vk_can_fuse_rope_set_rows check, so both fused paths fall back to the un-fused sequence on Mali.

Symptom: first llama_decode submit returns vk::Device::getFenceStatus: ErrorDeviceLost; the resulting uncaught vk::DeviceLostError is rethrown from ~llama_context() during teardown, aborting the whole process. Pre-b9341 (b8828) the Vulkan backend had no GPU TQ matmul, so these ops graph-split to CPU and bitnet inference worked end-to-end on the same Mali-G715 at ~17.9 t/s. Restore the hybrid behavior on Mali/Adreno coopmat1 (KHR_coopmat) only — desktop GPUs (NVIDIA/AMD/Intel) and coopmat2 hardware are unaffected and keep the full GPU TQ path. Mirrors the existing GGML_OP_MUL_MAT_ID guard a few lines below, which already routes TQ2_0 MoE to CPU unconditionally. Verified on Pixel 9 (Mali-G715): bitnet_b1_58-large-tq2_0 now generates clean tokens with -ngl 999 (7.79 t/s gen) instead of device-lost on the first decode.

Mali does support f32xf32xf32 16x16x16 coopmats, this commit adds a new cm1 path to generate and use cm1 matmul shader for f32 input. Not requiring any conversion pass. --- b9840 rebase (fixup folded in): The cm1 f32 path was originally written against b9692, where aligned pipelines loaded a separate _aligned SPIR-V -- the pipeline-creation counterpart to the shader-gen changes in this commit. - upstream 0eb874d374 ("vulkan: make mul_mm ALIGNED a spec constant", #24689, lands at b9771) made alignment a runtime spec constant chosen by ggml_vk_mul_mm_spec, so aligned and unaligned pipelines now share one shader. Rebased onto b9840, the CREATE_MM_FP32 macro still referenced the _aligned_cm1_fp32 symbols (no longer emitted after the shader-gen fixup) and passed a bare warptile spec. - Fold this in so both pipelines select alignment via ggml_vk_mul_mm_spec(WARPTILE, aligned) and reuse the single cm1_fp32 shader, matching upstream's _128 block. --- ggml/src/ggml-vulkan/ggml-vulkan.cpp | 121 +++++++++++++++++- .../vulkan-shaders/vulkan-shaders-gen.cpp | 60 +++++---- 2 files changed, 148 insertions(+), 33 deletions(-) diff --git a/ggml/src/ggml-vulkan/ggml-vulkan.cpp b/ggml/src/ggml-vulkan/ggml-vulkan.cpp index ee5c93496b2b..3f4915dc4fbd 100644 --- a/ggml/src/ggml-vulkan/ggml-vulkan.cpp +++ b/ggml/src/ggml-vulkan/ggml-vulkan.cpp @@ -763,6 +763,13 @@ struct vk_device_struct { uint32_t coopmat_int_n;

With GGML_OPENCL_EMBED_KERNELS=ON the build fails before link because the four old .cl.h includes have no source. Restore the four kernel files from tetherto/master so the existing call sites resolve, add them to the embedded-kernel list, and switch the q8_0 include to the post-rename name (the file is a pure rename — same symbol kernel_gemv_noshuffle_q8_0_f32 — so the call site already matched).

Net effect: adds the TurboQuant (TBQ3_0/TBQ4_0, block=128 and block=64) and PolarQuant (PQ3_0/PQ4_0, block=128 and block=64) quantization formats, CPU reference implementations, KV cache integration. Resolution notes (lossy fast-path): - ggml_type enum: kept qvac-b8828's NVFP4 (40) and Q1_0 (41); renumbered the TBQ/PQ family to 42..49 so GGML_TYPE_COUNT is now 50. Symbolic references in TBQ shaders/code are unchanged; only numeric slots shifted by +2. - llama-context: fixed PR's direct-compare against n_embd_head_k against the qvac-b8828 indexed-accessor API (n_embd_head_k() with default il=0). - llama-graph: kept HEAD's self_k_rot / self_v_rot[_swa] members and mctx->set_input_*_rot routing instead of PR's direct set_input_hadamard writes; ggml_rotate_hadamard callsites updated. (Partial) squashed commits: - kv-cache: route TBQ/PQ K/V to CPU buft when the chosen Vulkan device's SET_ROWS pipeline for the requested cache type is null. - fix: default attention rotation to off; opt-in via LLAMA_ATTN_ROT_ENABLE=1. - ggml-vulkan,kv-cache: support TBQ/PQ head_dim multiples Allow Qwen3.5-style 256-wide KV heads to use base TBQ/PQ blocks and apply TBQ QJL correction per 128-wide sub-block in Vulkan flash attention. - fix: enable attention rotation by default only for low-bit TBQ/PQ KV caches.

Rather than revert b9518's FA, this integrates both: - Generic FA (F16/BF16/Q4_0/Q4_1/Q5_0/Q5_1/Q8_0/Q1_0) keeps b9518's runtime FaTypeK/V decode unchanged. The shared FA shaders gate it behind LLAMA_UPSTREAM_FA_MIXED_TYPES, which vulkan-shaders-gen.cpp defines for the generic variants. - TBQ/PQ ride on dedicated per-type compile-time SPIR-V modules (flash_attn_f32_f16_[_][_cm1|_cm2]) that include turbo-quant/flash_attn_base.glsl for the bit-packed codebook decode and the QJL (Johnson-Lindenstrauss) Stage-2 correction. ggml-vulkan's three FA pipeline loops select these per (k_type, v_type) via CREATE_FA_TBQ. The QJL correction is applied to the Q*K^T score for TurboQuant K only (matching the CPU vec_dot reference); PolarQuant and all V decode are Stage-1 (codebook x scale). Same-type and mixed K/V (TBQ/PQ on K; PQ, Q4_0, Q8_0 or F16 on V) are supported on scalar, coopmat1 and coopmat2. Also includes: TBQ/PQ mul_mat (mul_mat_vec FHT/QJL epilogue + standalone mul_mm QJL correction pass), dequant, copy_to/from_quant + set_rows (incl. cooperative TBQ_COOP and norm-correction variants), the Metal MUL_MAT/MUL_MAT_ID reject for TBQ/PQ, llama-bench cache-type parsing, the test-backend-ops TBQ/PQ MUL_MAT + FLASH_ATTN_EXT sweeps, and the test-turboquant.sh / test-copy-tbq-subgroups / kv-cache perf+perp harness. The scalar FlashAttn MMQ (_int8) path is disabled fork-wide: the import reworked the scalar shader's MMQ path into the compile-time turbo-quant decode, so the generic _int8 module no longer compiles; the non-MMQ FA path covers the integer-dot quant types on every backend. Validated on RTX 4090 (Vulkan, coopmat2): test-backend-ops MUL_MAT and FLASH_ATTN_EXT for tbq*/pq* all pass against the CPU reference at the 5e-4 NMSE threshold.

Rebased onto b9840, the TurboQuant block still emits the old _f32/_f32_aligned/_f16/_f16_aligned variants with load_vec_a_unaligned, which no longer matches the shared mul_mm.comp. - Fold this in so each TQ/PQ type emits one shader carrying B_TYPE_SCALAR and drops the _aligned variant, exactly like upstream's _128 block. --- ggml/src/ggml-common.h | 8 + ggml/src/ggml-metal/ggml-metal-device.m | 2 +- ggml/src/ggml-vulkan/ggml-vulkan.cpp | 988 ++++++++++- .../vulkan-shaders/copy_from_quant.comp | 16 +- .../vulkan-shaders/copy_to_quant.comp | 16 + .../vulkan-shaders/dequant_funcs.glsl | 5 +- .../vulkan-shaders/dequant_funcs_cm2.glsl | 10 + .../vulkan-shaders/dequant_tbq3_0.comp | 33 + .../vulkan-shaders/dequant_tbq4_0.comp | 28 + .../vulkan-shaders/flash_attn.comp | 157 +- .../vulkan-shaders/flash_attn_base.glsl | 12 +- .../vulkan-shaders/flash_attn_cm1.comp | 162 +- .../vulkan-shaders/flash_attn_cm2.comp | 208 ++- .../vulkan-shaders/mul_mat_vec_tbq3_0.comp | 114 ++ .../vulkan-shaders/mul_mat_vec_tbq4_0.comp | 109 ++ .../vulkan-shaders/mul_mm_funcs.glsl | 41 +- .../mul_mm_tbq_qjl_correction.comp | 159 ++ .../ggml-vulkan/vulkan-shaders/tq_utils.glsl | 103 ++ .../turbo-quant/copy_to_quant.glsl | 348 ++++ .../turbo-quant/dequant_funcs.glsl | 46 + .../turbo-quant/dequant_funcs_cm2.glsl | 43 + .../turbo-quant/flash_attn.glsl | 47 + .../turbo-quant/flash_attn_base.glsl | 760 +++++++++ .../vulkan-shaders/turbo-quant/types.glsl | 142 ++ .../src/ggml-vulkan/vulkan-shaders/types.glsl | 2 + .../vulkan-shaders/vulkan-shaders-gen.cpp | 219 ++- tests/CMakeLists.txt | 7 + tests/ruler-bench.sh | 679 ++++++++ tests/test-backend-ops.cpp | 158 ++ tests/test-copy-tbq-subgroups.cpp | 878 ++++++++++ tests/test-kv-cache-quantization-perf-agg.py | 435 +++++ tests/test-kv-cache-quantization-perf.sh | 1518 +++++++++++++++++ tests/test-kv-cache-quantization-perp-agg.py | 435 +++++ tests/test-kv-cache-quantization-perp.sh | 1241 ++++++++++++++ tests/test-kv-cache-ruler.py | 746 ++++++++ tests/test-quantize-fns.cpp | 644 ++++++- tests/test-quantize-perf.cpp | 463 ++++- tests/test-turboquant.sh | 435 +++++ tools/llama-bench/llama-bench.cpp | 12 + 39 files changed, 11151 insertions(+), 278 deletions(-) create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/dequant_tbq3_0.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/dequant_tbq4_0.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/mul_mat_vec_tbq3_0.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/mul_mat_vec_tbq4_0.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/mul_mm_tbq_qjl_correction.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/turbo-quant/copy_to_quant.glsl create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/turbo-quant/dequant_funcs.glsl create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/turbo-quant/dequant_funcs_cm2.glsl create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/turbo-quant/flash_attn.glsl create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/turbo-quant/flash_attn_base.glsl create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/turbo-quant/types.glsl create mode 100755 tests/ruler-bench.sh create mode 100644 tests/test-copy-tbq-subgroups.cpp create mode 100644 tests/test-kv-cache-quantization-perf-agg.py create mode 100755 tests/test-kv-cache-quantization-perf.sh create mode 100644 tests/test-kv-cache-quantization-perp-agg.py create mode 100755 tests/test-kv-cache-quantization-perp.sh create mode 100644 tests/test-kv-cache-ruler.py create mode 100755 tests/test-turboquant.sh diff --git a/ggml/src/ggml-common.h b/ggml/src/ggml-common.h index 4b98eaddfd9d..617e01c42993 100644 --- a/ggml/src/ggml-common.h +++ b/ggml/src/ggml-common.h @@ -449,7 +449,15 @@ typedef struct { } block_iq4_xs; static_assert(sizeof(block_iq4_xs) == sizeof(ggml_half) + sizeof(uint16_t) + QK_K/64 + QK_K/2, "wrong iq4_xs block size/padding"); +// TurboQuant/PolarQuant block layouts are only consumed by host C/C++ code (CPU +// quant + type traits).

On hardware with +// gl_SubgroupSize < 32 (Intel Xe/Arc at 8/16, ARM Mali, Qualcomm Adreno, +// some AMD configurations) those ops reduce within a subgroup, not the +// whole workgroup, so the original shader silently produced wrong bytes. +// The shader is now parameterized on the SG_SIZE spec constant and takes +// a shared-memory "stitch" path for SG_SIZE < 32. This test exercises +// the stitch path on devices that only have one native subgroup size, +// by forcing the pipeline's requiredSubgroupSize + SG_SIZE spec const to +// 8/16/etc. +// +// How it works: +// Since GGML_VK_TBQ_COPY_SG_SIZE is consumed at Vulkan device init (once +// per process), we need a separate process per SG value. This binary +// self-spawns: in "child" mode it runs exactly one (SG, type) combination +// and prints a machine-readable summary line. In "parent" mode it forks +// itself for every combination and aggregates the results. +// +// Accuracy metric: +// The GPU and CPU quantizers compute the same math but in different float +// orders (horizontal reductions across subgroups vs. scalar sums), so +// byte-exact equality is not guaranteed -- we report both "bytes match" +// and a dequantize NMSE against the f32 input, and we also compare GPU +// dequantize vs. CPU dequantize so SG==32 vs SG==8 is a direct numerical +// comparison. The fast-path (SG>=32) and stitch-path (SG<32) are required +// to land within a tight NMSE tolerance of each other: if the stitch +// implementation is wrong, NMSE blows up to O(1). +// +// Performance: +// For each (SG, type) we time N repetitions of the copy on the device and +// report ms/iter and GB/s (input bytes).

It then overwrote pimpl->model with the caller-provided model, freeing the file-loaded model while its context and samplers still referenced it. Destroying that stale context (~llama_context via llama_free) then read the freed model -- a heap-use-after-free. It also ran the EOG logit-bias and sampler setup twice (once per model). Add a private empty common_init_result() constructor and use it in this overload so the externally-loaded model is adopted into a fresh result, with the context and samplers built only from that model.

Its comment claimed tensors_by_name was populated by create_split_backend_buffers, but it never was: the only population site iterates ml.ctx_map after loading, and on the incremental path ml.ctx_map is already empty by then (each split's contexts are moved into ctxs_bufs and erased per-split as they upload). The non-incremental path still has its contexts in ml.ctx_map, so it was unaffected. With tensors_by_name empty, the duplicate fell through, was re-created bound to its source split, and triggered a second create_split_backend_buffers for that split after release_split() had already freed its file -- hence the "file not found" error. This fix populates tensors_by_name inside create_split_backend_buffers, capturing each split's tensor pointers while the file is still mapped (the pointers stay valid across the subsequent ownership move into ctxs_bufs). The duplicate lookup now resolves the original and no longer re-reads a released split. Reproduced and verified with tests/test-model-load-memory-split on the 8-shard tied-embedding Llama-3.2-1B-Instruct-Q4_0 model; 3-shard Qwen3 and 8-shard bitnet split models continue to load.

Numerically validated on a Galaxy S25 (Adreno 830): identical region count and OCR output vs CPU.

CPU, CUDA and Vulkan already provide it; Metal was the only backend missing it, so ggml_conv_2d_dw_direct() aborts there and callers must fall back to the im2col + per-channel batched-matmul lowering (ggml_conv_2d_dw), which is very slow on Metal for depthwise-heavy networks (e.g. MobileNetV3 feature extractors). The kernel is modelled on the existing kernel_conv_2d: a grid-stride loop with one thread per output element and byte-stride (nb) addressing, templated on the weight type (f16/f32). It differs only in that there is no inner input-channel loop — a depthwise output channel reads exactly its matching input channel (ic == oc) and the per-channel K*K weights, so it reuses ggml_metal_kargs_conv_2d with OC == channels and nb03 as the per-channel weight stride. Wiring mirrors CONV_2D: supports_op (f16/f32 weight, f32 input/output, contiguous weight), pipeline getter (kernel_conv_2d_dw__f32), and the op dispatch. Handles both whcn and cwhn layouts via nb strides. --- ggml/src/ggml-metal/ggml-metal-device.cpp | 22 +++++ ggml/src/ggml-metal/ggml-metal-device.h | 1 + ggml/src/ggml-metal/ggml-metal-device.m | 5 + ggml/src/ggml-metal/ggml-metal-ops.cpp | 85 ++++++++++++++++ ggml/src/ggml-metal/ggml-metal-ops.h | 1 + ggml/src/ggml-metal/ggml-metal.metal | 114 ++++++++++++++++++++++ 6 files changed, 228 insertions(+) diff --git a/ggml/src/ggml-metal/ggml-metal-device.cpp b/ggml/src/ggml-metal/ggml-metal-device.cpp index fd2e8ed3f31b..a39c1a3fa7b4 100644 --- a/ggml/src/ggml-metal/ggml-metal-device.cpp +++ b/ggml/src/ggml-metal/ggml-metal-device.cpp @@ -1878,6 +1878,28 @@ ggml_metal_pipeline_with_params ggml_metal_library_get_pipeline_conv_2d(ggml_met return res;

Encoder / preprocess: - clip.cpp: Qwen3VL batch_size>1 path; per-tile attention with M-RoPE; sequential mode encodes tiles one-by-one; tile-size mismatch logs instead of aborting - mtmd-image.cpp: aspect-ratio-aware grid selection over all col×row ≤ max_tiles pairs; dyn_size fallback for sub-tile images - mtmd.cpp: tile-major decoder position mapping; full-image nx/ny = tile×grid - qwen3vl.cpp: batched inp_raw; per-tile M-RoPE views; attn_out accumulation Squashes the review / robustness fixes that shipped on top of the feature: - fall back to sequential on batched-encode OOM (check the previously ignored ggml_backend_sched_alloc_graph return) - honor preproc_max_tiles; drop inert per-tile M-RoPE offsets; extract pick_grid_by_log_ratio; crop via img_tool::crop; broadcast pos embedding - extract preprocess_dyn_size_aligned shared by dyn_size and the qwen3vl small-image fallback; align via patch_size*n_merge Part of the qvac fork's mtmd feature set carried across the b9518 -> b9840 rebase.

Add a LLaVA-NeXT-style global overview: a downscaled full image (tile_px × tile_px) prepended to the batch and encoded as its own 1×1 chunk before the tile grid, so seam-split text stays readable while the tiles are left untouched. DocVQA ANLS (batched, n=50): 0.816 -> 0.917. - clip_image_f32_batch.has_overview marks entries[0] as the overview - qwen3vl preprocessor builds the thumbnail for the multi-tile path (disabled / small-image dyn_size paths unaffected) - mtmd.cpp emits the overview as a 1×1 mrope chunk, then the tile grid Squashes the fixes that shipped on top of the overview: - clear has_overview after splitting the overview chunk; guard front(); assert remaining entries == grid_x*grid_y so future layout drift fails loud - replace the raw-dim (img ≤ tile_px) threshold with a canvas upscale guard: pick grid, compute the target canvas, fall back to dyn_size only if the canvas would upscale the image in either dimension - default --image-tile-mode to sequential - adapt to this branch's private clip_image_u8 nx/ny: read dimensions via img.get_size() and drop an unused batch_size local, so mtmd compiles on the fork (branch-local, not from upstream) Part of the qvac fork's mtmd feature set carried across the b9518 -> b9840 rebase.

They were never caught because the op was only reachable indirectly via the autograd path, which happened to mask several of them. - K (snapshot slot count) was read from state->ne[1], which is always == head_size, not K. Caused crashes/hangs whenever K != head_size. Fixed by deriving K from the incoming gradient tensor's shape instead (CPU, Metal, Vulkan). - CPU used the wrong memory stride (per-head instead of per-sequence) when locating a sequence's initial state, silently reading the wrong sequence's data whenever n_seqs > 1. - Vulkan/Metal multiplied a state offset by K where the state tensor has no K dimension at all; invisible when K=1, wrong otherwise. - CPU/Vulkan/Metal had a leftover loop zeroing out non-existent "extra" state-gradient slots for K>1, corrupting adjacent scratch memory. - CPU/Vulkan/Metal mapped tokens to snapshot slots in the reverse order the forward op uses. Every prior check injected a uniform gradient (e.g. via a SUM reduction) across all slots, so the reversal never changed the result and went undetected. Only caught by feeding distinct gradient values per slot against an independent from-scratch reference implementation. Verified against cross-backend agreement (CPU vs Vulkan), the existing finite-difference gradient checks, and a hand-written independent Python/numpy reference implementation of the delta-rule recurrence (forward values, and backward gradients via finite differences on that same reference) for hand-picked and randomized cases including K=1, K>1 exact-match, K>1 overflow, and n_tokensne[1];

On Mali, AUTO now picks the explicit (mul_mat) path for short sequences, where it is faster, and flash-attn for long ones, where explicit OOMs. The choice is per-image, gated by n_patches with a memory-aware cutoff, and guarded by an OOM-to-flash-attn rebuild fallback. Default-on for Mali only (other GPUs keep prior behavior); override via MTMD_CLIP_AUTO_FA_MIN_KV. * vulkan/CMake: source pinned Vulkan / SPIRV-Headers from the build tree's _deps (offline) for the Android NDK build, falling back to the upstream repos when absent. * mtmd-debug, mtmd: gate the per-op eval callback behind MTMD_DEBUG_CB_EVAL (clean encoder timing by default) and add an in-process flash-attn config sweep + embedding accuracy check used for the on-device tuning.

Allocate the repackable ones in ggml's CPU "repack" extra buffer type instead, so they get repacked into the interleaved layout at load and hit the fast i8mm/AVX2 GEMM. Selection is per-tensor via a ggml_backend_dev_supports_op probe (mirrors llama's buft_supported): only tensors the backend can actually repack+matmul go there, so conv weights / biases / norms stay in the default buffer, and on arches with no repack kernel it is a no-op. Weight loading is made per-tensor host-aware since weights now span the host default buffer and the non-host repack buffer. Output is bit-identical. Opt out with MTMD_CLIP_NO_REPACK=1.

Fall back to dyn_size when no grid fits. Add a global overview thumbnail at entries[0]. Add the --image-max-tiles CLI/env override (1..256), applied after load_hparams so GGUF defaults don't clobber it, and clamp preproc_min_tiles so a low override can't produce an empty candidate set on InternVL-family models. Guard the log-ratio division against zero-dimension images. Hardening: - Validate clip.vision.preproc_max_tiles read from the GGUF: clamp to [1,256] (the --image-max-tiles range) and fall back to 4 with a warning, matching the InternVL branch. A crafted/corrupt value could otherwise drive an oversized fitting.reserve() and OOM on load or first inference. - Size fitting.reserve() to max_tiles*ln(max_tiles) (the actual candidate count) instead of max_tiles*2, which undershot ~3x at the top of the range. - Fail a zero-dimension image gracefully (LOG_ERR + return false) instead of GGML_ASSERT, so one malformed upload fails its own request rather than aborting the whole server. Callers already treat false as a per-request error. - Doc/log consistency: reflow --image-max-tiles help to the sibling --image-* style, add the --image-tile-mode/--image-max-tiles rows to the cli/server READMEs, and log preproc_max_tiles as "(custom value)" when overridden. --- common/arg.cpp | 11 ++++ common/common.h | 1 + tools/cli/README.md | 2 + tools/mtmd/clip.cpp | 32 +++++++++++- tools/mtmd/clip.h | 3 +- tools/mtmd/mtmd-cli.cpp | 3 +- tools/mtmd/mtmd-image.cpp | 89 ++++++++++++++++++++++----------- tools/mtmd/mtmd.cpp | 2 + tools/mtmd/mtmd.h | 4 ++ tools/server/README.md | 2 + tools/server/server-context.cpp | 1 + 11 files changed, 117 insertions(+), 33 deletions(-) diff --git a/common/arg.cpp b/common/arg.cpp index 56f6e9758e60..8ced6cd2d782 100644 --- a/common/arg.cpp +++ b/common/arg.cpp @@ -2395,6 +2395,17 @@ common_params_context common_params_parser_init(common_params & params, llama_ex params.mtmd_batch_max_tokens = value; } ).set_examples({LLAMA_EXAMPLE_SERVER}).set_env("LLAMA_ARG_MTMD_BATCH_MAX_TOKENS")); + add_opt(common_arg( + {"--image-max-tiles"}, "N", + "maximum number of tiles for multi-tile vision models (e.g. Qwen3VL), overrides the\n" + "value from the GGUF; use when the GGUF lacks the key or the model default is wrong\n" + "for your model size (Qwen3VL defaults to 4, too low for 8B+ variants)", + [](common_params & params, int value) { + if (value < 1) { throw std::invalid_argument("--image-max-tiles must be >= 1"); } + if (value > 256) { throw std::invalid_argument("--image-max-tiles must be <= 256"); } + params.image_max_tiles = value; + } + ).set_examples(mmproj_examples).set_env("LLAMA_ARG_IMAGE_MAX_TILES")); if (llama_supports_rpc()) { add_opt(common_arg( {"--rpc"}, "SERVERS", diff --git a/common/common.h b/common/common.h index a3c95331faec..c9d5c2d203f3 100644 --- a/common/common.h +++ b/common/common.h @@ -620,6 +620,7 @@ struct common_params { int image_max_tokens = -1; common_image_tile_mode image_tile_mode = COMMON_IMAGE_TILE_MODE_SEQUENTIAL; int mtmd_batch_max_tokens = 1024; + int image_max_tiles = -1; // override preproc_max_tiles from GGUF; -1 = use model default // finetune struct lr_opt lr; diff --git a/tools/cli/README.md b/tools/cli/README.md index f93ae914ce27..31d25804a0c3 100644 --- a/tools/cli/README.md +++ b/tools/cli/README.md @@ -164,6 +164,8 @@ | `--image, --audio, --video FILE` | path to an image, audio, or video file. use with multimodal models, use comma-separated values for multiple files | | `--image-min-tokens N` | minimum number of tokens each image can take, only used by vision models with dynamic resolution (default: read from model)

Fewer graph nodes and tensor descriptors, scaling with n_layer instead of n_layer*batch_size. Fix the M-RoPE position layout for batch_size>1: the mrope kernel reads section s of token i at positions[s*N + i] (N = n_pos*batch_size), so the buffer must be section-major across the full batched sequence, not tile- major. The old layout mis-indexed every section beyond the first tile, encoding (y,y) instead of (y,x). batch_size==1 (the sequential path) is unchanged.

Disable flash attention on GPU projectors without efficient (coopmat) FA (tools/mtmd/clip.cpp). Uses runtime proc_address resolution to query the backend — no compile-time backend dependency. Mali FA_SCALAR ~2.6x less efficient than the matmul path; coopmat-capable GPUs keep FA enabled. 2. Mali/Valhall warptile tuning (ggml-vulkan.cpp, VK_VENDOR_ID_ARM) — large q8_0 MMQ tile to 32-warp/16-wide layout; ~90->~124 GFLOPS/s. Self-disables if shared memory is insufficient. Vendor-wide: also speeds the LLM prefill on GPU. 3. NORM+MUL+ADD (layernorm) Vulkan fusion (norm.comp, generic_binary_head.glsl, vulkan-shaders-gen.cpp, ggml-vulkan.cpp) — one dispatch replaces three; mirrors rms_norm+mul. -26 dispatches/encode. NOT Mali-specific. Result (4-run CPU-matched, profiler-off): within-run GPU/CPU mmproj-encode ratio ~1.46x (baseline) -> ~1.12x (optimized); near-parity 1.09x at high resolution. Quality 37.8%==37.8% (delta=0).

Per-op profiling on temp-9341/Pixel 9 showed the "optimized" build's clip encode was byte-for-byte identical to baseline (FLASH_ATTN_EXT present, zero SOFT_MAX) — the FA-disable never fired. Fix: - ggml-vulkan.cpp: ggml_backend_vk_supports_efficient_fa() returns false for VK_VENDOR_ID_ARM (Mali coopmat is not fast FA). Real-coopmat desktop GPUs (NVIDIA/AMD/Intel) still report efficient FA and keep it. - clip.cpp: apply the gate on flash_attn_type != DISABLED (the addon enables FA by default, not AUTO-only) and default to disabling FA when the backend can't confirm efficient FA (the safe original behaviour).

Downgrade to AUTO instead and record the inefficiency in clip_ctx::fa_backend_inefficient, which now also enables the AUTO cutoff default (previously Mali-detection only) so any non-coopmat backend gets the per-image budget decision: explicit attention below the cutoff (fast on scalar-FA GPUs), memory-frugal scalar FA at/above it or when the explicit scratch would not fit device memory.

Two unbounded behaviours plausibly drive the fault and both are bounded here: - ggml_backend_opencl_graph_compute enqueued entire graphs (thousands of nodes, ~48 s of GPU work for the failing encode) with no intra-graph flush. Now clFlush every GGML_OPENCL_FLUSH_INTERVAL nodes (default 64, 0 disables) so the GSL command-buffer manager receives bounded batches. clFlush submits without stalling the host. - ggml_cl_flash_attn issued one dispatch covering all q rows; at n_q = n_kv = 16384 every workgroup loops the full KV, making a single very long kernel. Now chunked along q rows at GGML_OPENCL_FA_MAX_NQ rows per dispatch (default 4096, 0 disables) with a clFlush between chunks. The split is exact: the kernel resolves its q row relative to the Q/O/mask base offsets, is_causal is always 0 (masking is explicit) and alibi/sinks depend only on the head index, so shifting the row base via byte offsets while shrinking n_q is mathematically identical. No .cl kernel changes. The 512-token image-chunk decode is not implicated: the S25 VLM benchmark ran 304 full-512-row ubatch decodes cleanly. Only the giant monolithic encode (5-8x beyond anything previously run on this backend) triggers the fault. --- ggml/src/ggml-opencl/ggml-opencl.cpp | 70 ++++++++++++++++++++++++++-- 1 file changed, 67 insertions(+), 3 deletions(-) diff --git a/ggml/src/ggml-opencl/ggml-opencl.cpp b/ggml/src/ggml-opencl/ggml-opencl.cpp index f7471655cc82..fcd32312a240 100644 --- a/ggml/src/ggml-opencl/ggml-opencl.cpp +++ b/ggml/src/ggml-opencl/ggml-opencl.cpp @@ -18,6 +18,7 @@ #include #include +#include #include #include #include @@ -5730,6 +5731,22 @@ static void ggml_opencl_op_group_norm_fused(ggml_backend_t backend, ggml_tensor static ggml_status ggml_backend_opencl_graph_compute(ggml_backend_t backend, ggml_cgraph * cgraph) { ggml_backend_opencl_context *backend_ctx = (ggml_backend_opencl_context *)backend->context; + // QVAC-21914: bound the driver's per-submission work on giant graphs. + // Large vision graphs (e.g. a monolithic 16k-patch ViT encode: thousands + // of nodes, ~48 s of GPU work) enqueue everything between two host + // synchronization points.

Per-token LLM decode graphs never reach the budget by construction, so the decode hot path stays submission-free; the 16k-patch encode still flushes dozens of times. Single touch point in graph_compute (no more per-fusion-branch duplication). - ggml-opencl: both tunables move onto ggml_backend_opencl_context, resolved once at init with strtol-based parsing (clamp, warn on garbage instead of silently disabling the mitigation) and GGML_LOG_INFO'd like the file's other env knobs. FA chunking reads the context field. - ggml-opencl: GGML_ASSERT(is_causal == 0) before the FA chunk loop — the kernel's causal-boundary formula needs the TOTAL n_q, so chunks after the first would silently corrupt output if causal FA were ever enabled here; keep the invariant loud. Explicit n_q == 0 guard. - clip: rework the AUTO cutoff memory clamp. Total memory now provides the STABLE fast-path clamp (explicit scratch <= total/4); free memory (a volatile, load-dependent number) may only lower the cutoff further via the hard-fit requirement (scratch <= free), never the old free/2 heuristic that silently pushed normal-size Mali images onto the ~2.6x slower scalar-FA path under momentary memory pressure. No memory info at all now fails SAFE at a conservative 2048-patch cap instead of trusting the raw 4096 default (~3.2 GB scratch at n_head=16). The arithmetic is extracted into clip_fa_effective_min_kv() (pure, exposed via clip.h for tests). - tests: test-clip-fa-cutoff (pure CPU, locks in the fast path, the P2 regression guard, the fail-safe cap and edge cases; passing) and test-opencl-fa-chunking (chunked-vs-CPU numerical parity over unchunked / exact-chunk / partial-last-chunk / n_q==1, masked and unmasked, with GGML_OPENCL_FA_MAX_NQ=64 and a 1 MB flush budget; self-skips without a capable OpenCL device — PoCL lacks FP16, so it executes on Adreno-class hardware). - clip warmup comment: note ggml-opencl also lands in the "no efficient-FA query" bucket and its giant-encode fault is handled by the submission bounding inside that backend. GGML_OPENCL_FLUSH_INTERVAL (node-count knob) is replaced by GGML_OPENCL_FLUSH_WORK_MB; GGML_OPENCL_FA_MAX_NQ semantics unchanged. --- ggml/src/ggml-opencl/ggml-opencl.cpp | 107 ++++++++++++---- tests/CMakeLists.txt | 13 ++ tests/test-clip-fa-cutoff.cpp | 83 +++++++++++++ tests/test-opencl-fa-chunking.cpp | 178 +++++++++++++++++++++++++++ tools/mtmd/clip.cpp | 81 ++++++++---- tools/mtmd/clip.h | 7 ++ 6 files changed, 425 insertions(+), 44 deletions(-) create mode 100644 tests/test-clip-fa-cutoff.cpp create mode 100644 tests/test-opencl-fa-chunking.cpp diff --git a/ggml/src/ggml-opencl/ggml-opencl.cpp b/ggml/src/ggml-opencl/ggml-opencl.cpp index fcd32312a240..107ed7b133eb 100644 --- a/ggml/src/ggml-opencl/ggml-opencl.cpp +++ b/ggml/src/ggml-opencl/ggml-opencl.cpp @@ -19,6 +19,7 @@ #include #include +#include #include #include #include @@ -484,6 +485,13 @@ struct ggml_backend_opencl_context { bool has_qcom_subgroup_shuffle = false; // specifically cl_qcom_subgroup_shuffle bool disable_fusion; + // QVAC-21914 submission bounds (resolved once at init from env, logged there). + // flush_work_budget: bytes of estimated enqueued work per driver submission in + // graph_compute; 0 disables. fa_max_nq: max q rows per flash-attention dispatch; + // 0 disables chunking. + int64_t flush_work_budget; + int fa_max_nq; + bool adreno_has_large_buffer; bool adreno_use_large_buffer; ggml_cl_compiler_version adreno_cl_compiler_version; @@ -4998,6 +5006,31 @@ static ggml_backend_opencl_context * ggml_cl_init(ggml_backend_dev_t dev) { backend_ctx->disable_fusion = getenv("GGML_OPENCL_DISABLE_FUSION") != nullptr; + // QVAC-21914 submission bounds.

On Windows mtmd builds as a shared library exporting only the MTMD_API-decorated public API; the internal clip_* symbols are absent from mtmd.lib, so test-clip-fa-cutoff (the first cross-DLL-boundary consumer of a clip_* symbol) failed to link (LNK2019). Linux/macOS export all default-visibility symbols, so it linked there. Move the function inline into clip.h (with its NO_MEMINFO_CAP constant); the test and clip.cpp both compile their own copy — no DLL export of an internal helper.

A null mask means no masking, i.e. bidirectional attention (the SigLIP vision and embedding encoders), while causal attention always supplies an explicit causal mask in this codebase (llama-graph.cpp build_attn passes a kq_mask filled with -INFINITY). The heuristic therefore wrongly made the bidirectional Qwen3-VL vision tower attend causally, so each patch only saw earlier patches and the image embedding was corrupted. Set is_causal = 0 unconditionally; causality is always expressed via the explicit mask. This cannot regress the LLM, which already passes a real causal mask (is_causal was already 0 for it) and relies on that mask. Document the invariant in ggml_cl_flash_attn: a null mask is treated as bidirectional, so any caller needing causal masking must supply an explicit causal mask rather than relying on shape inference.

Out-of-range lanes (the last partial BLOCK_M block) `continue` past the read and race ahead into the next tile load while active lanes are still reading l_k/l_v. With n_kv > BLOCK_N (e.g. the bidirectional vision tower, n_kv=247) this corrupts the shared tiles. Add a trailing barrier(CLK_LOCAL_MEM_FENCE) at the end of the K/V block loop and guard the score computation with `if (my_query_row < n_q)` instead of an early continue. flash_attn_f32_f16.cl already uses that guard + trailing barrier after b9840's redesign, so it is left unchanged. Also guard zero source dimensions in ggml_cl_upscale: the sf* scale factors divide by the source dims, so a zero source dim yields +inf; the existing early-exit only covered zero destination dims. Re-ported onto b9840's rewritten OpenCL flash-attn (b9840 widened the score unroll to j += 4; only the divergence guard + trailing barrier are re-applied, the body is unchanged). Squashed re-port of dc64397d2 + b7ad6d4e2. The barrier fix is a GPU-scheduling race whose only proof is on-device; the original b7ad6d4e2 validated on S25 Ultra / Adreno 830 (Qwen3-VL GPU vision projector matches CPU exactly, Delta 0.0 pp, ~26% faster on encode).
