Ocarina of Time can freeze while first-use task/mesh pipelines compile, even after conventional shader warm-up. This adds optional mesh prewarming and fixes cached pipeline prebuild adoption, refill, and cancellation. Real draws still wait for compilation and preserve graphics; speculative state never enters the runtime draw cache.
Add Prewarm predicted mesh shaders (experimental), default off, with global/per-game overrides. It controls mesh prewarming and native mesh shader-library use; changes apply at the next game start.
Prepare up to 512 candidates by default, pairing archive shaders with observed mesh contexts. Run before gameplay or on one low-priority worker, releasing temporary pipelines and descriptors after use.
Correct render-target selection and constant-table extraction, preserve distinct shader specializations, and retry failed cached prebuilds from live state. Rebuild prepared shaders to benefit from the extraction fixes.
Dependencies and attribution: merge #579 and #741 first; their commits are included in this branch and currently appear in the diff.
Tyler Biscoe (tyler-gg):constant-table extraction, selectively ported without the authoritative compute-prebuild changes.
jarynclouatre:native task/mesh library renderer, adapted to this PR’s opt-in and bounded warm-up. Their broader candidate generator is not included.
Validation: Release build, all five CTest suites, and 61 Python tests pass on ae537ceaf7, including reload lifecycle and truncated-cache regressions. The seven CodeRabbit findings are addressed, covering reload, persisted warm-up completion, conversion guards, and documentation. Earlier NVIDIA checks built all 512 candidates without rejections or driver failures and passed enabled/disabled and house-exit checks. The latest GPU recheck was blocked by an existing emulator session; AMD/Intel remain unverified. Upstream CI requires maintainer approval.
Earlier intro benchmark: New Game through the unskipped intro to player control (~372 s), Ryzen 7 9800X3D / RTX PRO 6000 / Linux. Same executable (6e83fcede3), identical historical runtime-cache seed, separate empty driver caches, one pass per configuration. The two warm-up columns differ only in the mesh checkbox.

Worst stalls improved, but p99 and mean rate worsened versus baseline. These are settings comparisons on an earlier build, not evidence of a final-head speedup. Method and results. The separate 512/1024/2048 comparison has a driver-cache confound and cannot establish a budget-related performance benefit.

…pute build logs
With EDEN_NX2_FAST_FIRST=1 a pipeline built while the game runs is first
created with VK_PIPELINE_CREATE_DISABLE_OPTIMIZATION_BIT and used as soon
as the driver returns it. The optimized build follows on a worker and
replaces it at a later draw or dispatch. On a demanding Switch 2 test
title the first-visit stutter is the driver compile (draws held up to
7 s of every 10 s with an empty driver cache); this trades it for a
slower shader during that time.
Compute pipelines built synchronously log their driver build time when
it is over 100 ms (Nx2Perf compute_build), since a dispatch waits for
the whole build.
Off by default; nothing changes without the variable.
EDEN_NX2_HEAVY_SKIP=<N> skips the draws of a native pipeline with at
least N converted instructions over all stages while the driver builds
it, instead of holding every draw behind it ("1" picks 4000). On a
demanding Switch 2 test title every driver build over 500 ms was above
4000 instructions, and those made about 90% of the compile time.
A heavy draw is still held when skipping it could lose data for good:
the pipeline writes storage or uses transform feedback, or its render
target was not cleared this frame, or is a new small target (a baked
texture rather than a scene-sized image redrawn every frame). Clears
are reported to the pipeline cache for this (NoteClear). Held draws
build their own pipeline instead of queueing behind skipped builds.
Environments report their converted instruction count (CodeWords) so
the pipeline knows its size. Counters are logged every 10 s, and held
draws over 100 ms log the pipeline size, the reason they were held and
the render target size (Nx2Perf held_draw).
Off by default; nothing changes without the variable.
EDEN_NX2_COMPUTE_WARM=<file> loads compute programs prepared offline
from the game's own shader archives (pipeline cache format, no recorded
reads) and builds them on 4 low priority threads after the disk cache
has loaded. The pipelines are thrown away; they only fill the driver's
shader cache, so a dispatch that later converts to the same SPIR-V finds
the driver build ready instead of waiting seconds for it. Programs
already in the disk cache are left out.
Reads a file record does not hold are answered with guesses
(FileEnvironment::SetGuessMissing / VideoCommon::GuessMissing) instead
of an error. With the defaults about 95% of the programs converted to
the same SPIR-V as the runtime records on the test title.
Tools:
- shader-sweep --guess-missing [--guess-cbuf0, --guess-cbuf-other,
--guess-texture-type, --guess-pixel-format, --guess-storage-pointer,
--guess-storage-pointer-other] translates records with missing reads
the same way, and accepts cache version 53.
- shader-sweep --override-out FILE writes the lowering as a program
override record and reports the program's native_key.
- tools/nx2/make_compute_warm.py builds the warm-up file from a static
shader dump (extract_static_shaders.py output).
Off by default; nothing changes without the variable.
…GPL)
With EDEN_NX2_GPL=1 and a device that supports
VK_EXT_graphics_pipeline_library with fast linking, graphics pipelines
are linked from per-stage libraries instead of being built whole.
Without the variable the device is created exactly as before (the
extension stays out of the extension tables).
Each stage gets its own descriptor set (set index = stage index,
independent sets, plain descriptor sets, Bindings::descriptor_set in
the SPIR-V backend) with bindings from 0, and the fragment stage's
rescaling bits start at fixed indices, so a stage's SPIR-V and library
do not depend on the partner stage's resources.
Pre-rasterization and fragment shader libraries are cached in
PipelineCache, keyed by the emitted SPIR-V hash, the stage's set
layout, the state the part bakes in, the dynamic state list and the
render pass; a worker that needs a library another worker is building
waits for it. Vertex input and fragment output libraries are built per
pipeline, then fast linked. EDEN_NX2_GPL_OPTIMIZE=1 adds an optimized
link on a worker, swapped in like the fast first build. A failed
library or link falls back to a monolithic pipeline with the same sets.
Task/mesh, transform feedback, static rasterizer discard and stages
with too many textures or images for the split rescaling bits stay on
the monolithic route.
PipelineCache::WarmGraphicsLibraries builds a pipeline's shader
libraries with no draw; with a single stage and no partner it builds
only that stage's library. Nx2Perf gpl stats are logged every 10 s.
Based in part on suyu-main 3157ae0ce0 and f80bbc701a (library cache
built outside the lock, fast then optimized link, link statistics);
unlike there, shader libraries are shared across partner stages.
EDEN_NX2_GRAPHICS_WARM=<file> (with graphics pipeline libraries on)
builds the game's vertex and fragment programs as single-stage
libraries in the background after the compute warm-up. The file is
streamed (it can be over a gigabyte); worker threads take the next
entry under the reader's lock. Libraries built by the warm-up are
not kept (GraphicsPipelineLibraryCache::SetNoRetainOnThisThread), so
only the driver's disk cache keeps them and a later pipeline with those
stages costs a link.
tools/nx2/make_graphics_warm.py writes the file from a static shader
dump: one single-stage entry per unique vertex or fragment program,
with draw state taken from the most common state in pipeline caches
the game recorded (--runtime-cache). --validate compares the generated
entries' SPIR-V with the runtime records.
Off by default; nothing changes without the variable.
…tus bar progress
The warm-up files no longer need the offline scripts. A game list entry
"Prepare shaders (warm-up)" (with Rebuild and Delete) runs
ShaderWarm::BuildWarmFiles in a progress window with Cancel; games do
not start while it runs. The builder:
- reads the game's RomFS through the VFS (.nup base and update
packages, other formats through the loader);
- extracts shader programs with C++ readers for the archive formats
(zstd with the game's dictionaries, DCX, LZ4, SARC, BND4, BFSHA/BNSH,
effect bundles, CGSB, SHN, BAHS v11), a port of the PR zortos293#214
extractor with the same checks;
- lowers and converts them in process with the runtime code layout, on
low priority threads in program order, and writes the per-title
warm-compute.bin and warm-graphics.bin atomically, with the same
records make_compute_warm.py and make_graphics_warm.py write. Draw
state comes from the title's v53 pipeline caches when there are any,
else from built-in defaults measured on one test title.
At boot the warm-ups load the title's warm files when
EDEN_NX2_COMPUTE_WARM / EDEN_NX2_GRAPHICS_WARM are unset. A warm-up
that ran to the end writes a .done marker (file size and write time,
entries, driver version, device ID, cache version); a matching marker
skips that warm-up at the next boot. Rebuild and Delete remove the
warm files, markers and temporary files.
Progress goes through ShaderNotify (SetWarmProgress / GetWarmProgress,
lock-free, 4 updates a second) to the status bar, next to the shader
build count: compute and graphics counts, with a percent when the
total is known.
A "Shader libraries" setting (use_graphics_pipeline_library) in the
advanced graphics tab turns on graphics pipeline libraries like
EDEN_NX2_GPL=1.
yuzu_cmd gets a hidden --build-warm <game> <title id> <output dir>
[--defaults | caches] that runs the builder without booting the game
(test hook).
…ent of fast-first compute, warm path encoding, builder exceptions, JSON summary, offline tool failures and defaults)
- vk_graphics_pipeline: the GPU thread checks a has_pipeline flag the build sets before it
completes, instead of reading pipeline while the scheduler thread swaps in the optimized one.
- vk_compute_pipeline: a retired pipeline also waits for its pending optimized build.
- vk_pipeline_cache: open the warm files and their markers through one path in its native
encoding (environment overrides stay native narrow).
- shader_warm_dialog: a builder exception is reported as a failed build instead of leaving the
worker thread; deleting uses the shared DeleteWarmFiles (markers and temporary files too).
- yuzu-cmd: escape the error text in the JSON summary.
- make_compute_warm.py: a hung or unstartable sweep counts as a failed program.
- make_graphics_warm.py: clear error when a stage has no runtime records.
- shader-sweep: --guess-missing guesses no storage pointers in banks 1-17, as the emulator does.
…he right after a version bump
The builder read only the current version's runtime cache. Just after a version bump (53 to 54)
that cache does not exist yet, so it fell back to the built-in defaults; a first-visit walk on the
test machine after that warm-up still compiled many libraries in game (0.5 to 0.8 s each). Read
the newest cache of a version with the same record layout instead.
The warm-up threads only stopped when the pipeline cache was destroyed, late in shutdown. Until
then they kept compiling (16 threads in one test), the emulation thread did not stop in time and
was terminated. They now also end, after their current build, when the loading stop token fires.
…river
Pipelines fast-linked from graphics pipeline libraries draw white fringes
around alpha blended effects on AMD's Windows driver (clouds, particles
and glows in a test title, RX 7800 XT, driver 26.10.1). The
same SPIR-V and per-stage descriptor sets built as a monolithic pipeline,
or linked with link time optimization, draw correctly. Libraries there keep
link time optimization info and every link is optimized;
EDEN_NX2_GPL_FAST_LINK=0/1 overrides the choice on any driver.

…N_NX2_COMPUTE_NOINLINE)
The multi-second whole-process freezes in a test title (one dungeon, 1.4-5.6 s) are the
first dispatch of a new compute pipeline waiting for NVIDIA's driver compile. Configure
records RunBuild + a condvar wait on the scheduler thread, so the scheduler, the GPU thread
behind it and the guest behind its present fence all stop until vkCreateComputePipelines
returns. A native program's global memory functions (DefineGlobalMemoryFunctions: the
address tested against every storage buffer, ~300-870 instructions each) are called from
dozens of places, and NVIDIA inlines every call: single shaders took 2-13 s to build.
Mark functions of 128+ instructions called from 2+ places DontInline when the compute
module is built (the translation cache keeps the SPIR-V as emitted, so cached and fresh
stages build alike and the cache key is unchanged). EDEN_NX2_COMPUTE_NOINLINE=0 builds the
SPIR-V as emitted. Also: "Nx2Perf compute driver build" (>100 ms, with CPU time and thread)
and "Nx2Perf compute first dispatch ... waited" (>20 ms) log lines, and
EDEN_NX2_COMPUTE_SPIRV_DUMP=<dir> to dump compute SPIR-V for offline timing.
RTX 3080 Ti, driver 615.78.08:
- Offline, all 618 compute shaders of a scene-tour translation cache, NVIDIA disk cache off:
the 92 with marked functions 246 s -> 72.5 s of compile, shaders over 1 s 78 -> 20
(the other 526 took 11.7 s and none over 1 s). VK_PIPELINE_CREATE_DISABLE_OPTIMIZATION_BIT
does not shorten NVIDIA's compile; running spirv-opt first makes it longer.
- Harness, cold pipeline + NVIDIA caches, open field -> town -> dungeon, interleaved:
first-dispatch waits off 51.3 / 51.6 s total (max 5.27 / 5.51 s, 18 / 19 over 1 s),
on 22.1 / 24.1 s (max 3.14 / 4.04 s, 7 / 6 over 1 s); log silences over 1 s 47 / 48 -> 35 / 35.
- Second session (warm caches) has no compute waits in either mode: the freeze is paid once
per new compute shader per driver cache.
Ported to this branch: the translation cache hit path and the "Nx2Perf compute driver
build" log are left out (this branch has no translation cache, and already logs compute
driver builds through MakeComputePipeline and the build trace). Every compute module,
including the fast-first and compute warm-up builds, goes through ComputeModuleCode.

(cherry picked from commit 2fa4ecb5f048df579f58b98db095f0707875bcc3)
…X2_GRAPHICS_NOINLINE)
Graphics stages of native programs carry the same global memory functions as compute
(DefineGlobalMemoryFunctions), called from many places and inlined at each one by the driver.
Run the same DontInline pass on graphics SPIR-V in EmitShaderModule, where every graphics module
is made: monolithic pipelines, pipeline libraries, deferred worker emission and the graphics
warm-up. EDEN_NX2_GRAPHICS_NOINLINE=0 builds the SPIR-V as emitted.
The pipeline library key (spirv_hashes) is now the hash of the words handed to the driver, after
the pass, so a library built by the warm-up and one needed in game share a key only when their
modules are identical. The device SaveShader copy and the log dumps stay the emitted SPIR-V, as
for compute. Test: vertex and fragment entry points are marked like compute.
(cherry picked from commit e4e4fbea121b7e59584539e671a0ca57ee80a1c8)
The compute and graphics warm-ups each ran on a fixed 4 threads. EDEN_NX2_WARM_THREADS=N
(1 to 32) sets the count for both; anything else keeps 4, with a warning. The threads stay at
low priority, and the existing "on N low priority threads" log lines show the count used.
(cherry picked from commit cfb80df71b445613c36a0d60ccb708ada6828d40)
…starts its own
LoadDiskResources can run again in the same pipeline cache (another title or
program). The earlier load's warm-up threads were neither stopped nor joined,
so StartComputeWarm and StartGraphicsWarm returned early and never warmed the
new title, and clearing warm_cancel let old threads keep working on the
previous title's file. A later load now cancels and joins them, drops the old
stop callback and resets the compute-done flag first.
…ode, driver failures keep a graphics warm-up pending, heavy skip needs full clears, no warm-up deletion while preparing)
- The warm-up marker also records whether shared shader functions are
built as calls (compute and graphics); after that setting changes, the
driver compiled different SPIR-V, so the warm-up runs again. Markers
without the field no longer match.
- Graphics warm-up entries now end as built, not buildable (a guess the
translation rejects) or refused by the driver. A warm-up with driver
failures writes no marker, so the next start tries again.
- A library-only build whose library the driver did not make reports a
failed build instead of returning as if built.
- Heavy skip: a color clear counts only when it clears every channel, and
a target counts as rebuilt only when each of its attachments was cleared.
- Deleting a game's warm-up while it is being prepared is refused.
…hole attachment and every depth/stencil aspect; the deletion guard applies to the title being prepared)
- A clear marks a target rebuilt only when it covers the attachment's own
size and layers (scaled like the framebuffer), not just the framebuffer,
which can be smaller than an atlas or array. Pitch-linear color targets
never count.
- A combined depth/stencil target counts only when depth is cleared and
stencil is cleared with every bit written.
- Deleting a game's warm-up is refused only while that same game's
warm-up is being prepared.
…ame starts
A pending shader warm-up can now run on the loading screen, as a new
"Preparing shaders x / y" stage after the cached pipelines, on every CPU
thread at normal priority; the game starts once it is done. Before, it only
ran in the background at low priority while the game played, with more
stutter until it ended and a game that felt slow.
New setting "Prepare shaders before the game starts" (Ask, Always, Never;
Configure, Graphics, Advanced). With Ask the desktop app asks at launch when
the title has a warm-up that never finished, with "Don't ask again" keeping
the answer as the setting. Never keeps the background warm-up. Where nothing
asks (command line, Android) Ask acts as Never. Closing the game during the
stage cancels the warm-up; it runs again at the next launch.
The new LoadCallbackStage::Warm is last, so the other stages keep their
values; Android shows it as shader building.
The warm-ups' builds go into the driver pipeline cache, but the timed flush
counts only pipelines built during play, so a finished warm-up reached the
file only at the next boot, game change or clean close, and was lost when
the app ended otherwise (reported on Linux/RADV by IorekByr, where the
cache lives in that file).
The pull request adds Vulkan graphics pipeline libraries, asynchronous pipeline builds, and shader warm-file generation and loading. It adds desktop and command-line warm-up workflows, frame-time measurement tools, tests, documentation, and Ocarina benchmark records.
Changes: Vulkan Pipeline Construction and Cache
Layer / File(s)
Summary
Pipeline settings and device support src/common/settings.*, src/video_core/vulkan_common/*, src/video_core/renderer_vulkan/pipeline_build.h
Settings and device checks add graphics pipeline library, shader inlining, and mesh warm-up controls.
Descriptor layouts and shader emission src/shader_recompiler/backend/*, src/video_core/renderer_vulkan/pipeline_helper.h, src/video_core/spirv_inline_control.*, src/video_core/shader_environment.*, related tests and build files
Descriptor bindings and layout helpers support per-stage descriptor sets. Shader environments expose instruction counts, and SPIR-V processing can mark selected shared functions as non-inline.
Graphics pipeline libraries and linking src/video_core/renderer_vulkan/vk_pipeline_library.*, src/video_core/renderer_vulkan/vk_graphics_pipeline.*, src/video_core/renderer_vulkan/vk_pipeline_cache.cpp
Graphics builds can construct and cache pipeline libraries, link them, use stage-specific descriptor sets, and fall back to monolithic pipelines.
Asynchronous builds and prebuild scheduling src/video_core/renderer_vulkan/vk_compute_pipeline.*, src/video_core/renderer_vulkan/vk_pipeline_cache_prebuild.h, src/video_core/renderer_vulkan/vk_pipeline_cache.cpp, src/tests/video_core/pipeline_build.cpp
Compute and graphics paths add fast builds followed by optimized replacements. Prebuild scheduling handles queued work, demand, bounded captures, shutdown, reload, and cached-pipeline retries.
Heavy-build draw handling and cache integrity src/video_core/renderer_vulkan/vk_pipeline_cache.*, src/video_core/renderer_vulkan/vk_rasterizer.cpp, src/video_core/renderer_vulkan/vk_scheduler.h
The cache tracks full target clears and target history to hold or skip selected draws during builds. Cache serialization checks for a complete snapshot before replacing the existing file.
Shader Warm-File Generation and Use
Layer / File(s)
Summary
Archive parsing and warm-record formats src/video_core/shader_warm/shader_archives.*, src/video_core/shader_warm/warm_records.*, src/video_core/shader_warm/warm_defaults.cpp, src/video_core/CMakeLists.txt
New readers extract shader records from supported archive formats. Record helpers lower programs, create cache entries, and select runtime-derived or default graphics templates.
Warm-file and mesh-candidate generation src/video_core/shader_warm/shader_warm_builder.*, src/video_core/shader_warm/mesh_warm_builder.*, src/video_core/shader_warm/mesh_warm_validation.h, src/tests/video_core/mesh_warm_builder.cpp
The builder discovers archives, converts and deduplicates programs, infers vertex attributes, and writes compute, graphics, and mesh warm files. Mesh recipes validate donors and generate bounded candidates.
Vulkan warm-up and shader translation src/video_core/renderer_vulkan/vk_pipeline_cache.*, src/video_core/shader_environment.*, src/video_core/shader_notify.h, tools/shader-sweep/main.cpp
Vulkan loads and validates warm files, builds pipelines, reports progress, handles cancellation, and coordinates driver-cache saves. Shader translation supports configured guesses for missing context.
Warm-up controls and application entry points src/yuzu/game/game_list.*, src/yuzu/main_window.*, src/yuzu/shader_warm_dialog.*, src/yuzu/loading_screen.cpp, src/yuzu_cmd/yuzu.cpp, settings and translations
The desktop interface adds prepare, rebuild, and delete actions, a cancellable progress dialog, and a pre-start prompt. The command-line entry point can build warm files and print a JSON result.
Frame-Time Measurement and Benchmark Records
Layer / File(s)
Summary
Present-window API and measurement workflow src/core/debugger/nx2_debug_tools.*, tools/nx2/debug_mcp.py, tools/nx2/measure_stutters.py, tools/nx2/test_measure_stutters.py, src/tests/core/nx2_debug_server.cpp
The frame-time API adds present-window queries and precise interval output. The measurement script replays input in chunks, validates samples, and saves timing results.
Benchmark records and comparison documentation docs/nx2/benchmarks/*, docs/nx2/debug-mcp.md
The benchmark records document three Ocarina configurations and their measurements. The guide describes the measurement workflow and mesh-budget comparisons.

Possibly related issues
zortos293/Lichii#601: The pull request adds bounded mesh-pipeline warm-up, which addresses part of the first-boot warm-up request; the broader request remains open.
zortos293/Lichii#697: The pull request changes cached pipeline prebuild adoption and refill, which overlap with the issue’s preload and cache-retention objectives. Its requested defaults and asynchronous discard behavior are not included.
zortos293/Lichii#405: The pull request adds bounded mesh prewarming, but does not add the requested per-session compile diagnostics or full cold-cache timing breakdown.
Preparing shaders from the game list fails for games stored as loose ExeFS dumps, which reduces the benefit of the new warm-up feature for them. Other game formats and normal gameplay are unaffected, so merging is acceptable once the open path is fixed or the limitation is accepted.

Squashed from zortos293/Lichii PR zortos293#717 (head eb3553b, base 92f0212). Conflicts against tuned+zortos293#643+zortos293#761 resolved keeping both sides' semantics:
- fixed_pipeline_state.cpp: RefreshBlending is called unconditionally, as on tuned: a blend register written without raising Dirty::Blending left a stale key (forest fog without blending = black screen on GPUs without dynamic blend state, e.g. AMD). PR zortos293#717's extracted helper has the identical body, mask fix-up included.
- pipeline_helper.h: IsUncomparable (tuned) and the BINDMEMO block (zortos293#717) both kept; PushImageDescriptors runs the depth-compare guard on the non-memo path, so recorded memos hold the guarded descriptor.
- vk_compute_pipeline.cpp: cbuf_address (tuned, shared with the handle-table fast path) and read_word/handle_pages (zortos293#717) both defined; the handle-table callback now also records sampler handles in bind-memo mode, keeping the one-handle-per-element invariant the memo lookup and its fallback rely on.
- texture_cache.h DeleteImage: MarkStale (zortos293#463) plus the bindings epoch bump (zortos293#717); texture_cache_base.h keeps both new includes.
- vk_pipeline_cache.{h,cpp}: WarmGraphicsLibraries (zortos293#761) and ResetStateWatch (zortos293#717) both declared; the next-pipeline memo stat now sits inside the retry gate; both Report calls kept.
- vk_rasterizer.cpp: tensor-program log (zortos293#643) and the write-handoff owner hook (zortos293#717) both kept in the constructor; the heavy-skip NoteClear block and the deferred-clear other_pass_open computation both kept.
…s to
The draw state template was counted over the whole pipeline key, hash slots
included, so nearly every state was unique and the first record won; with
the color formats then zeroed, every warm library was built for a render
pass with no color target and depth off, which no real draw uses, so the
driver could not reuse them.
The template now takes the most common render target first (samples, depth
on and format, color formats), then the most common state among those
records without the hash slots and vertex attribute types. The built-in
defaults are regenerated with the same rule. make_graphics_warm.py follows.
Found by jarynclouatre, who also measured the effect (draws held on
vertex+fragment pipelines 2,135 ms to 214 ms) with a first version of this
change.

Port the constant-table extraction and serialization subset of befc0c6. Keep all predictions transient; exclude the static-context and authoritative compute prebuild changes. Include external tables in conversion and output deduplication and preserve paired mesh variants.
Test explicit graphics/compute serialization, BNSH variation tables, BAHS optional table bounds, mesh specialization and render-target selection.

Adapt the renderer subset of c83423d. Omit the vertex-input library, suppress tessellation state and keep task/mesh push constants compatible across library and fallback layouts.
Latch the existing experimental mesh checkbox at game start and keep mesh emulation and existing unsupported cases monolithic. The bounded one-worker warmer releases speculative libraries and uses a new completion stamp sensitive to GPL support. Keep observed-context recipes instead of importing unvalidated metadata-derived mesh registers.

The historical 512 intro arm populated its explicitly created NVIDIA cache directory. The 1024 and 2048 launchers configured missing directories and never populated them. Retain numeric observations but withdraw performance and preparation-cost attribution across those arms. The original three-arm intro test is unaffected by this setup error.

Review comments at @docs/nx2/debug-mcp.md:
- Around line 206-209: Update the Ocarina budget comparison summary to note that
unmatched NVIDIA disk-cache setup confounds the comparison, so performance and
startup-cost conclusions against the 512 baseline are withdrawn. Retain the
stated default of 512.
Review comments at @src/qt_common/config/shared_translation.cpp:
- Around line 301-305: Update the tooltip in the shader_warm_at_boot setting so
it explicitly names the Always, Never, and Ask options and describes each
option’s behavior: Always runs the warm-up on the loading screen, Never runs it
in the background at low priority while the game plays, and Ask prompts at each
launch. Preserve the existing description of the warm-up and when the game
starts.
Review comments at @src/video_core/renderer_vulkan/vk_pipeline_cache_prebuild.h:
- Around line 92-95: Update the prebuild-cache lifecycle guarded by mutex so a
later disk load can admit and start prebuilds after Stop() has drained the
cache. Clear stopped and reset slot and capture accounting only when no workers
or in-flight captures remain, so outstanding reservations are not discarded.
Review comments at @src/video_core/renderer_vulkan/vk_pipeline_cache.cpp:
- Around line 1613-1621: Update compute and graphics warm-up completion so
WriteWarmMarker runs only after the queued Vulkan cache save succeeds, or when
the driver owns the cache or Vulkan pipeline caching is disabled. Reuse the
promise-and-wait pattern in StartMeshWarm to obtain the serialization result,
preserve the existing completion and cancellation conditions, and do not write a
marker when serialization fails or is interrupted.
Review comments at @src/video_core/shader_warm/mesh_warm_builder.cpp:
- Around line 315-327: Update AddVariation to catch exceptions from LowerProgram
and GraphicsEnv using the established handling pattern in Converter::Convert,
increment impl->skipped, and return for the affected program. Preserve the
existing behavior for ordinary LowerProgram failures and the prepared-byte limit
check.
Review comments at @src/yuzu/main_window.cpp:
- Around line 4449-4453: Update OnGameListConvertToNup to stop conversion before
it begins when a running shader warm-up is reading the same game; inform the
user and return without starting conversion or deleting sources. Use
shader_warm_dialog to check the warm-up state, and establish that it targets the
game being converted before blocking.
Review comments at @tools/nx2/make_graphics_warm.py:
- Around line 117-139: Update runtime_records to stop cleanly at a truncated or
empty record: check that the count and each environment header, computed
environment body, and key fit within the remaining data, and return when count
is zero. Preserve normal record parsing and yielding for complete records.

After Stop(), the next load cannot add or start prebuilds. For affected pipelines missing from the runtime cache, first use creates them from live state and can cause a stall.

Drain and reopen prebuilds with fresh accounting and per-file membership. Persist conventional warm-up caches before completion markers, reject old premature markers, and keep cancellation and disabled-cache paths pending.
Also isolate mesh conversion exceptions, block same-source NUP conversion during shader preparation, tolerate truncated offline cache tails, clarify warm-up options, and correct the budget comparison caveat. Add reload-budget and truncated-record regressions.

Resolve loose ExeFS directories before opening them.
For a loose-dump game entry, the game list passes the ExeFS directory to OpenGame. OpenFile rejects that directory, so Prepare shaders fails with Cannot open the game file. Resolve the directory to its main file as normal boot does.

…der prewarm, opt-in switches (rebased on build-125)
Squash-merge onto build-125; 26 conflicted files hand-resolved.
Key fusions: build-125's precache system (precache_shaders,
PrecacheShaders flow, WarmStamp markers, precached-pipelines list)
coexists with the PR's warm-up system (shader_warm_at_boot,
compute/graphics/mesh warm files, mesh candidates): both boot flows
run (each no-ops on its own setting); BuildWarmFiles is the PR's
generalized builder, keeping build-125's ClassifyGameFile archive
selection and its no-archives behaviour (files written empty, no
hard fail). LowerProgram/ComputeEntry keep both call forms as
overloads; FileEnvironment::Deserialize keeps build-125's bounded
signature with an unbounded default for the warm builders;
PipelineCache keeps both save APIs and the PR's bool
SerializeVulkanPipelineCache; duplicate WarmPending/WriteWarmCount/
DeleteWarmFiles definitions deduplicated (DeleteWarmFiles extended
to the union of both file sets).

AGENTS.local.md adapts the upstream agent rules to the owner's PC
(RX 580 on RADV, 6 threads, 16 GB, Arch Linux): fork layout, what the
tuned branch already carries, local build and debug-server workflow,
and the hardware facts that override upstream measurements.
tools/local/build.sh is the one-command incremental build and
tools/local/play.sh launches the frontend with the debug server on.
Updated for the build-125 rebase: the tuned stack is now zortos293#259, zortos293#354,
zortos293#643, zortos293#761 and zortos293#717 (zortos293#756 and zortos293#463/zortos293#818 are upstream's own now, and
a7dd2ce is covered by the zortos293#717 fusion); AGENTS.local.md also records
the open 0.75x scaling-noise problem and its retest matrix.

… GetFlushArea)
vk_pipeline_cache.cpp: the fused precache/warm function (the
build-125 precache flow and PR zortos293#761's warm-up in one body) lost its
closing brace; WaitForWarmUps and everything after it parsed as
nested inside it.
vk_rasterizer.cpp: GetFlushArea kept build-125's bare lock-scope
block opener, but in the fused body the lock lives inside the
skip_textures branch and the block's close was eaten; the stray
opener is removed (the skip flags are used below it, so they must
stay in function scope).

The file carried both sides' layouts: warm_before_start twice

its own anonymous namespace), RequestWarmBeforeStart twice (kept

Finish the zortos293#656/zortos293#761/zortos293#579 shader stack without replacing zortos293#1021 recorded recipes.
Add shared-function SPIR-V controls on both prepared and translated paths, optional
fast-first builds, layout-correct motion bindings, cancellation/reload ownership,
and driver-persistent mesh warm markers. Preserve compute retirement and bounded
prebuild capture budgets. Keep new performance timing diagnostics opt-in.

Validation: targeted Windows clang-cl syntax checks; standalone SPIR-V inline
control tests pass (5 cases, 25 assertions). Full linking and gameplay validation
remain the parent integration's responsibility. The frontend syntax check needs
the main build's generated ui_main.h, which is not present yet.

Ocarina of Time can freeze while first-use task/mesh pipelines compile, even after conventional shader warm-up. This adds optional mesh prewarming and fixes cached pipeline prebuild adoption, refill, and cancellation. Real draws still wait for compilation and preserve graphics; speculative state never enters the runtime draw cache.
Dependencies and attribution: merge #579 and #741 first; their commits are included in this branch and currently appear in the diff.
Validation: Release build, all five CTest suites, and 61 Python tests pass on
ae537ceaf7, including reload lifecycle and truncated-cache regressions. The seven CodeRabbit findings are addressed, covering reload, persisted warm-up completion, conversion guards, and documentation. Earlier NVIDIA checks built all 512 candidates without rejections or driver failures and passed enabled/disabled and house-exit checks. The latest GPU recheck was blocked by an existing emulator session; AMD/Intel remain unverified. Upstream CI requires maintainer approval.Earlier intro benchmark: New Game through the unskipped intro to player control (~372 s), Ryzen 7 9800X3D / RTX PRO 6000 / Linux. Same executable (
6e83fcede3), identical historical runtime-cache seed, separate empty driver caches, one pass per configuration. The two warm-up columns differ only in the mesh checkbox.Worst stalls improved, but p99 and mean rate worsened versus baseline. These are settings comparisons on an earlier build, not evidence of a final-head speedup. Method and results. The separate 512/1024/2048 comparison has a driver-cache confound and cannot establish a budget-related performance benefit.
