video_core: emulate tensor programs only where cooperative matrices run them; stand in otherwise (imports #143 by @felipecsl) - #643
Ocarina of Time (0400486024DEC000) runs neural networks as Ampere HMMA programs: the title and cutscene movie enhancement network (11 programs, the largest has 768 HMMAs) and the gameplay upscaler. #582 and #583 run them on VK_KHR_cooperative_matrix. Where the device has no cooperative matrices (MoltenVK on every Mac, Intel's Windows driver in #272, older GPUs), every HMMA is expanded in software. That takes minutes of shader compilation and leaves the title and the intro movies at single-digit to ~20 FPS. On an M1 Pro the movie network alone measured about 50 ms of GPU time per frame.
#143 by @felipecsl already stands in for these networks with a plain upscale, but only on Mesa's Intel driver.
Setting: "Switch 2 tensor programs: Auto / Native / Stand-in" (Graphics > Advanced, per game). Auto applies the rule above, and the decision is logged once when the renderer starts.
Fix: the stand-in stopped after the first frame. A program's first dispatch is rejected as a matrix multiply and reaches the stand-in. Every later dispatch fails on the cached pipeline as Native compute pipeline unavailable, which the stand-in did not match. As a result Ocarina's title movie upscaled once and then stayed black. KeplerCompute now remembers which programs were rejected as matrix multiplies and routes their later rejections to the stand-in too.
The "Ocarina of Time anti-aliasing: No sharpening" option skips the gameplay anti-aliasing chain before dispatch, so it takes precedence for that network. This PR covers the default setting, the movie network, and the other games' tensor programs on these devices.
Testing
On a MacBook Pro with an M1 Pro (16 GB, MoltenVK):
The log shows Tensor programs: upscale stand-in (cooperative matrices unavailable, setting Auto). The movie network's programs are rejected and the final pass is blitted on every frame.
Before the persistence fix, the same build showed the title with a black movie background.
Not tested: gameplay on other GPUs, and the other HMMA games (Fire Emblem, Star Fox, Kirby, Fast Fusion) on stand-in devices. Those now take the stand-in where they were emulated before. Native restores the old behaviour.
Added an advanced Tensor Programs setting with Auto, Native, and Stand-in modes. Auto selects behavior based on renderer support; Stand-in can use image-based upscaling when native tensor programs are unavailable.
Donkey Kong Bananza continues to use emulation regardless of the selected mode.
Changes to this setting require restarting the renderer to take effect.
Documentation
Added guidance on tensor-program modes, compatibility, and fallback behavior.
…grams (imports zortos293#143 by @felipecsl)
Ports UpscaleInsteadOfNativeProgram unchanged from Eglantine (585e457, 82e34d4 and
follow-ups, as of upstream/nx2 e736dfd). The upstream merge (zortos293#109) dropped it, so a
rejected tensor-core program left its output unwritten.
…orts zortos293#143 by @felipecsl)
Lichii lowers every HMMA. On Mesa ANV (Intel Arc B390), Ocarina of Time's upscaler network
(768 matrix multiplies) takes minutes to compile, then runs at about 8 FPS with a black
picture. Reject matrix multiplies there (Donkey Kong Bananza's still run, as upstream does)
so the upscale stand-in draws instead. Other drivers keep emulating the network.
…ork (imports zortos293#143 by @felipecsl)
With its network rejected (Mesa's Intel driver), the gameplay frame flickered between the
scene, black and grey every few seconds. The network reads the frame packed as RGB9E5
(written as R32_UINT storage) and writes a B10G11R11 image as wide or wider; the
stand-in only paired images of one format, and its scan matched stale handles in the
network's constant buffer (a 480x270 bloom level at +0xa0) with the output instead.
Pair the RGB9E5 frame with the output before that scan, and copy it through an RGB9E5
view (a host-only render target format for the 2D copy).
…n (imports zortos293#143 by @felipecsl)
The gameplay network's RGB9E5 input holds the square root of the tonemapped frame (it
matches with gamma 2.0, scale 1.00, median error 0.0002); the network squares it back.
Copied as is, every value came out brighter (0.25 shown as 0.5): a white haze over the
scene. Add a squaring copy (SrcCopySquare, next to SrcCopySrgbToLinear) for that pair.
…rts zortos293#143 by @felipecsl)
The stand-in sometimes picked the wrong images for Ocarina's gameplay
network, leaving the 3D black for seconds while the HUD kept drawing:
- a stale 2560x1440 A8B8G8R8 handle (+0xb8) made the widest image wider
than the real output, so the RGB9E5 pair was rejected;
- stale handles at title 4's and Fortune's Weave's slots (+0x328/+0x348)
formed a pair before Ocarina's was looked for;
- the output picked was the scene target the packed frame aliases (a blit
onto itself) or an item-get pass's target.
Count only B10G11R11/E5B9G9R9 images for the widest, look for Ocarina's
pair before the other titles' slots, prefer the network's own slots
(input cbuf0+0xc0, output +0xd0) when they hold an E5B9G9R9 -> B10G11R11
pair at different addresses, and otherwise skip outputs at the input's
address.
From persluffy-cl's comment on zortos293#143, tested there on an RX 6600 XT.

…un them (zortos293#272, zortos293#237)
Replace zortos293#143's Intel-Mesa check with a capability rule. Switch 2 networks (Ocarina of
Time's movie enhancement and upscaler) are emulated only when HMMA runs on Vulkan
cooperative matrices (Profile::support_cooperative_hmma, zortos293#582); MoltenVK, Intel on
Windows and older GPUs draw the upscale stand-in instead. Donkey Kong Bananza stays
always emulated.
Add the "Switch 2 tensor programs" setting (Auto, Native, Stand-in; Graphics > Advanced,
per game) and log the decision once when the renderer starts.
Builds on zortos293#143 by @felipecsl.
…n after its first dispatch
The first dispatch of a tensor program is rejected as a native matrix multiply and reaches the
stand-in. Later dispatches fail on the cached pipeline with "Native compute pipeline unavailable",
which the stand-in did not match, so Ocarina of Time's title movie upscaled once and then showed
black. Remember the programs rejected as matrix multiplies and route their later rejections to the
stand-in too.
Adds a per-game tensor-program setting and renderer capability routing. When matrix multiplies are rejected, the dispatch path can select image pairs and use format-specific copy operations or, for eligible Fortune’s Weave dispatches, temporal upscaling.
Adds the tensor_programs setting with Auto, Native, and Stand-in choices. The renderer reports cooperative HMMA support, selects emulation behavior, and logs the mode.
Matrix-multiply rejection and dispatch handling src/shader_recompiler/frontend/ampere/lower_to_maxwell.h, src/video_core/shader_environment.*, src/video_core/engines/kepler_compute.*, src/tests/video_core/spirv_software_matrix.cpp
Passes a rejection flag into matrix lowering. The dispatch path records programs rejected for matrix multiplies and attempts the stand-in on later rejection.
Searches prioritized resource slots and then scans handles for compatible input and output images. Adds Ocarina-specific pair selection and optional sample diagnostics.
Stand-in copy and format handling src/video_core/engines/fermi_2d.h, src/video_core/engines/kepler_compute.*, src/video_core/gpu.h, src/video_core/surface.cpp, src/video_core/texture_cache/texture_cache.h, src/video_core/host_shaders/*, src/video_core/renderer_vulkan/blit_image.*
Adds bilinear image copies, format-specific conversion, and conditional temporal upscaling. Adds a square-color shader and RGB9E5 host-format handling.
Debug sampling and tracing run on the 21st stand-in dispatch without any opt-in, causing a one-time GPU stall and reads of title-specific addresses. The tensor-program setting is also treated as changeable mid-game although a restart is required. Both are small, localized fixes that should be made before or shortly after merge.

Explanation
The title names the main behavior change: tensor programs are emulated only where cooperative matrices run them, and an upscale stand-in is used otherwise. The changeset matches this. It adds a tensor_programs setting (Auto, Native, Standin), a cooperative HMMA query in the pipeline cache, EmulatesNativeTensorPrograms() in the rasterizer and kepler_compute, reject_matrix in the shader lowering path, and UpscaleInsteadOfNativeProgram for the stand-in. The title is long at 17 words and includes a parenthetical import reference (#143), which is noise. Those points do not make the title unrelated or vague, so the check passes.

Set runtime_modifiable to false for tensor_programs.
The declaration passes runtime_modifiable=true. The tooltip in shared_translation.cpp and docs/TENSOR_PROGRAMS_STANDIN.md both say a change needs a game restart.
A runtime change does not re-lower programs that already ran:
KeplerCompute::EmulatesNativeTensorPrograms() reads the value live. It is consulted when a ComputeEnvironment is built.
The renderer logs the mode only once, in the constructor.
ComputePipelineCacheEntry keeps a failure string for programs that were rejected. Those programs do not return to the native path.
A mid-game switch therefore leaves some programs on the old mode. The UI also suggests the change applies at once.

Debug diagnostics run by default in production.
sample_at defaults to 20 when EDEN_NX2_SAMPLE_AT is unset. trace_at defaults to 30 when EDEN_NX2_TRACE_AFTER_UPSCALE is unset. On the 21st stand-in dispatch, this code runs without any opt-in:
It calls rasterizer->FlushRegion on the input and output images. This stalls on GPU work.
It reads six hardcoded, title-specific GPU addresses (0x8116a03000 and others). Each read covers about 14 MB of guest memory at a 4 KiB stride. Those addresses may map unrelated or unmapped memory in other games.
It also copies *input into an unused fake entry.
The 30th dispatch sets g_nx2_trace_draws_after_upscale = 40, which enables draw tracing.
The comment above the block says "Debug". Run the block only when the environment variable is set. Remove the hardcoded address loop.

Tested on RDNA2 together with #657, and it fixes the title and cutscene movies there.
Setup: RX 6650 XT, AMD 2.0.353, Ryzen 5 5600X, Windows 11. nx2 89440b29 (includes #657) + this PR, plus #571, #463, #573, #345, #408 and #251 (with #259 off), built as the clang-cl PGO variant. tensor_programs is Auto and oot_anti_aliasing is No sharpening. Measured with EDEN_NX2_MOVIE_CLOCK=1 and EDEN_DKB_FRAME_TRACE=1.
The log says VK_KHR_cooperative_matrix is emulated on this AMD GPU and Tensor programs: upscale stand-in (cooperative matrices unavailable, setting Auto).
~193 vs ~204 (movie audio audibly late, with 3 s of zero voice samples at the start)
201.5 vs 201.7 (sounds right)
eff3ccbe1438679d is also one of the shaders in BuildsUnoptimized for AMD proprietary drivers (#200), which probably explains why it costs so much there.
The gameplay network (0x1148fc8e00) gets the stand-in too. A 25-minute session ran with no crash and a clean shutdown.
Two things I noticed:
There was a 2.1 s hitch on the first gameplay frames, right after the network was rejected and stood in (t=906 → 917).
About 860 Info lines of DKB shader rejected ... Native compute pipeline unavailable across the session.
On an RTX 4050 Laptop (NVIDIA 621.14), Auto picks native and the movies behave the same as before.
…without cooperative matrix
Squashed from zortos293/Lichii PR zortos293#643 (head cef9eac). Keeps a matrix-rejected Kepler compute program on the upscale stand-in after its first dispatch, so cards with no cooperative-matrix hardware (Polaris included) stop falling off the tensor path.

…split GPU thread, caches, JIT, kernels)
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.
, zortos293#781, zortos293#655, zortos293#809 and others) into Rei-02
Conflicts:
- texture_cache: take upstream zortos293#818 (rebase of zortos293#463 with StalePages) and zortos293#817
(CopiesWriteWholeImage, 1x only) over our older copies of both; drop our
extra MarkStale in DeleteImage and the GpuModified clear it needed.
- settings / translations: keep tensor_programs (zortos293#643) and precache_shaders (zortos293#781).
- maxwell_3d: keep FrontNoteWrites/FrontNoteDraws (zortos293#345) and the sink reset (zortos293#488).
- query_cache: keep the zortos293#345 report counter and zortos293#337's fence flag.

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.

Problem
Ocarina of Time (
0400486024DEC000) runs neural networks as AmpereHMMAprograms: the title and cutscene movie enhancement network (11 programs, the largest has 768HMMAs) and the gameplay upscaler. #582 and #583 run them onVK_KHR_cooperative_matrix. Where the device has no cooperative matrices (MoltenVK on every Mac, Intel's Windows driver in #272, older GPUs), everyHMMAis expanded in software. That takes minutes of shader compilation and leaves the title and the intro movies at single-digit to ~20 FPS. On an M1 Pro the movie network alone measured about 50 ms of GPU time per frame.#143 by @felipecsl already stands in for these networks with a plain upscale, but only on Mesa's Intel driver.
Changes
UpscaleInsteadOfNativeProgram,LoweringOptions::reject_matrix, and Ocarina's gameplay pair fixes: the RGB9E5 input at cbuf0+0xc0 squared into the B10G11R11 output at +0xd0.HMMAon cooperative matrices (support_cooperative_hmmaorsupport_cooperative_hmma_16x16x16). Everywhere else the stand-in draws. Donkey Kong Bananza is always emulated, as in video_core: don't emulate tensor programs on Mesa's Intel driver; stand in for Ocarina's upscaler #143.matrix multiplyand reaches the stand-in. Every later dispatch fails on the cached pipeline asNative compute pipeline unavailable, which the stand-in did not match. As a result Ocarina's title movie upscaled once and then stayed black.KeplerComputenow remembers which programs were rejected as matrix multiplies and routes their later rejections to the stand-in too.docs/TENSOR_PROGRAMS_STANDIN.md.Interaction with #616
The "Ocarina of Time anti-aliasing: No sharpening" option skips the gameplay anti-aliasing chain before dispatch, so it takes precedence for that network. This PR covers the default setting, the movie network, and the other games' tensor programs on these devices.
Testing
On a MacBook Pro with an M1 Pro (16 GB, MoltenVK):
Tensor programs: upscale stand-in (cooperative matrices unavailable, setting Auto). The movie network's programs are rejected and the final pass is blitted on every frame.Not tested: gameplay on other GPUs, and the other HMMA games (Fire Emblem, Star Fox, Kirby, Fast Fusion) on stand-in devices. Those now take the stand-in where they were emulated before. Native restores the old behaviour.
