video_core: bounded wait for unbuilt Switch 2 pipelines (Ocarina of Time: draws held 14.7 s to 0.2 s per 10 s) - #465
With asynchronous shaders on, a Switch 2 (native Turing) draw whose graphics pipeline is still building is never skipped: CanDiscardPendingDraw returns false for native draws, so the GPU thread waits for the driver build. In Ocarina of Time (0400486024DEC000) on an RX 6700 XT, the existing 10 s runtime report showed up to 14,656 ms of draws held for unbuilt pipelines in one 10 s window, with single builds of up to 16.7 s. In game, the frame rate falls to 0 to 7 FPS the first time a new area is drawn (the forest, cutscenes). Until now the only way out was EDEN_NX2_ASYNC_DISCARD=1, which skips every pending draw and can leave effects missing.
This adds a middle ground: wait, but only up to a per-frame budget. The default is unchanged.
Changes
New setting native_async_draws (Graphics > Advanced, per game), enum NativeAsyncDraws:
Wait (default): the current behaviour.
Bounded: the draw waits for its pipeline, up to what is left of a per-frame budget. Once the frame's budget is spent, the frame's remaining unbuilt draws are skipped as with Skip.
Skip: pending native draws are skipped, the same as EDEN_NX2_ASYNC_DISCARD=1.
New setting native_pipeline_wait_ms (1 to 100, default 8): the per-frame budget for Bounded.
EDEN_NX2_ASYNC_DISCARD=1 still forces Skip, so existing setups behave the same.
PipelineBuild::WaitFor(std::chrono::microseconds) in pipeline_build.h: a timed wait on the build's existing mutex and condition variable (wait_for on complete). It returns whether the build finished. GraphicsPipeline::WaitBuilt(timeout) wraps it.
DecideNativePending(mode, can_discard, budget_left_us) in async_draw_policy.h: a pure constexpr function returning Wait, WaitTimed or Skip. It is the only place the decision is made, and it is covered by src/tests/video_core/native_pending_policy.cpp ([native_pending]).
The budget lives in PipelineCache. Only the GPU thread touches it, and PipelineCache::TickFrame resets it each frame.
Next to the existing runtime pipeline report, a new log line Bounded pipeline wait: X ms spent in the last 10 s (budget N ms per frame) shows what the mode costs, readable from a user log.
Trade-off.Bounded swaps a long stall for a short one. In the worst case a draw is missing for one frame, which shows as a flash. That is why Wait stays the default.
Related.#408 reduces how many pipelines get built mid-game. #411 warms pipelines up ahead of time. This PR changes what a draw does while a pipeline is still building, so it stacks with both. It touches the same stutter as #416 (GPU-thread pipeline stalls in Ocarina of Time) and #426 (why asynchronous shaders don't skip native draws), and the new Bounded pipeline wait log line is a small piece of the compile diagnostics asked for in #405.
Testing
Setup. Windows 11, Ryzen 7 5700X, RX 6700 XT (AMD proprietary driver), 32 GB. Handheld, resolution 1x, FSR 1, FXAA, GPU accuracy Fast, ASTC recompression BC3, async shaders on, EDEN_NX2_SPLIT=2, EDEN_NX2_FENCE_BATCH=1. Ocarina of Time (0400486024DEC000): Link's house, Kokiri village, the sword area and the training dummy, on a first visit.

0 to 7 FPS while new areas load
up to 40 FPS; short drops to ~10 FPS on area transitions and the first hit in combat
What the remaining drops are: about 400 pipelines translated on the GPU thread (5 to 220 ms per 10 s). This PR does not touch that; #408 targets it.
Visible side effect: with Bounded, a one-frame white flash on Link the first time he stepped into water, when the budget ran out.
Build. MSVC 19.44 (VS 2022 Build Tools), Ninja, Release, Qt 6.8.3. On this branch alone, on top of nx29fa4a71, I built video_core, qt_common, the touched yuzu objects and tests. [native_pending] passes.
Not verified
The FPS row is not a clean A/B. The Bounded run also had a community pre-compiled pipeline pack installed and EDEN_NX2_PRELOAD_ALL_PIPELINES=1 set; the Wait run had neither. The two log lines (draws held and Bounded pipeline wait) are what isolate this change, not the FPS.
One machine and one game. No NVIDIA or Intel run, and no other Switch 2 title.
The gameplay build. It had other local commits on top (an unrelated settings branch). This exact branch was built but not run in game.
MSVC flags. Five existing test files trip the project's /we4388 /we4389 on MSVC, so tests was built locally with _CL_=/wd4388 /wd4389. That flag is not part of this PR.
Added advanced graphics settings for handling native draws while their pipelines are still building: wait, skip eligible draws, or wait for a limited time.
Added a per-frame pipeline wait limit, configurable from 1 to 100 milliseconds and defaulting to 8 milliseconds.
The wait limit resets each frame. Draws that cannot be skipped continue to wait for their pipelines.
Scenario: Switch 2 (native Turing) draws whose graphics pipeline is still
building are never skipped, so the GPU waits for the driver build. On an
RX 6700 XT (Zelda OoT Switch 2) the log showed up to 14656 ms of draws held
in a 10 s window and single builds of 16.7 s.
Add native_async_draws (Wait, Bounded, Skip; default Wait keeps the current
behavior) and native_pipeline_wait_ms (per-frame budget, default 8 ms), both
in the Qt advanced graphics settings. Bounded does a timed condition-variable
wait on the pipeline build up to the per-frame budget, reset in
PipelineCache::TickFrame, then follows Skip. EDEN_NX2_ASYNC_DISCARD=1 still
forces Skip. The decision is a pure function covered by a Catch2 test.
Measured with Bounded at 8 ms on the same machine: at most 229 ms of draws
held per 10 s window, 10 to 614 ms of bounded wait per window, and a
one-frame flash when the budget runs out.

The Vulkan pipeline cache now supports configurable Wait, Bounded, and Skip handling for native draws with unbuilt pipelines. Bounded waits use a configurable per-frame time budget. The changes add timed pipeline-build wait APIs, settings translations, and policy tests.
The settings add Wait, Bounded, and Skip modes and a per-frame wait limit. DecideNativePending selects an action based on the mode, whether the draw can be discarded, and the remaining budget. Translations expose the settings, and tests cover the policy choices.
Timed waits and cache integration src/video_core/renderer_vulkan/pipeline_build.h, src/video_core/renderer_vulkan/vk_graphics_pipeline.h, src/video_core/renderer_vulkan/vk_pipeline_cache.h, src/video_core/renderer_vulkan/vk_pipeline_cache.cpp
Pipeline builds and graphics pipelines expose timed wait methods. The cache resets the native wait budget each frame and applies the configured policy to native draws. The EDEN_NX2_ASYNC_DISCARD=1 environment variable overrides the mode to Skip. Non-native draws continue to use the discard heuristic.

…th async copies
The batch merge of zortos293#413 and zortos293#465 left uses_async_copy unused, which GCC's -Werror rejects
and broke the non-PGO Linux builds. The barrier is only needed when the program issues
LDGSTS copies, as in zortos293#465.
Note for the record: #411 (referenced in this PR) continues in #579, rebased on top of this one. There the heavy-pipeline skip decides first, and draws it does not handle fall through to native_async_draws (Wait / Bounded / Skip) unchanged.
Brings in Lichii's Ocarina performance work: channel polling every 50 us
(zortos293#446), RangeSet on a sorted array (zortos293#481), skipping GPU-write invalidations
of empty caches (zortos293#250, replacing our earlier draft of it), bounded waits
for unbuilt pipelines (zortos293#465) and keeping never-used disk-cache pipelines
(zortos293#550). The new FPS limit (zortos293#270) feeds the host pacer's game frame interval.

…records
- EvictUnusedPipelines only evicts while more than 8,000 graphics pipelines are
cached, and then the longest unused ones a draw has used, down to 7/8 of the
limit (EDEN_NX2_PIPELINE_EVICT_ABOVE; 0 restores the old behavior). Prebuilt
pipelines no draw has used keep zortos293#550's budget. Ocarina of Time evicted 6,182
pipelines in a 37 min session (~1,000-2,400 cached at a time) and draws
waited 230 s in all for pipelines being built again.
- The first boot copies the cache version 53 records beside this version's
(vulkan_import, loaded after it) and merges the v53 used-pipeline list, so
pipelines a v53 build used are built at boot again. The records are the same
format: zortos293#432 bumped the version only for the SPIR-V it emits, and every record
is translated again when it loads. The v53 files are left as they are.
Skipping draws on unbuilt pipelines is left to zortos293#465's native_async_draws setting.

- Cache invalidations: upstream's ClaimCpuWrites first, then each cache's
lock once for all ranges.
- Our 256 MiB table-pointer cap gives way to zortos293#351's storage buffer reach.
- FlushQueryResults keeps the timed wait; macro DMA reads flush pending

* shader_recompiler: lower UISETP with an accumulate predicate and FSETP with a uniform operand
Two forms in a Pokopia scene shader that were rejected: UISETP (0x88c) that combines its result
with an accumulate uniform predicate (AND/OR/XOR, optionally negated), and FSETP with its second
operand in a uniform register (0xc0b).

* fs: iterate directories without the throwing overloads
The range-for loops in IterateDirEntries and IterateDirEntriesRecursively
step with operator++ and read entry.status(), both of which throw
filesystem_error. With Scan Subfolders on for C:/, operator++ threw
"Access is denied" on the second entry; nothing above the game list
worker catches it, so its thread pool thread terminated the process.
Step with increment(ec), read status(ec), and skip directories that
cannot be opened.
Assisted-by: Claude Opus 5.5 (crash dump analysis, implementation)
* game_list: keep the list disabled during the startup scan
MainWindow starts the first populate and then calls ResetViewMode, which
enabled the view while the worker was still scanning. Removing a game
directory then freed its row, and the worker's next AddEntry for that
directory crashed in QStandardItem::rowCount(). Keep the view disabled
until the populate completes, and repopulate on Remove so a running
worker never sees its rows freed and the other rows' GameDirRole
indices stay correct.

* hid: report non-zero sensor ranges in the six-axis IC information
GetSixAxisSensorIcInformation returned a zeroed structure, as the
information is never read from a controller. Nintendo Switch Sports
starts sensor fusion when a match begins, and nn::imu passes these
ranges to nerd::gyro_pointing, whose GyroPointingStateDetector checks
that the accelerometer and gyroscope ranges are above 0 and aborts
otherwise (2162-0001, right after "Play with a Single Controller").
Report the ranges of the Joy-Con and Pro Controller sensors, 2000 dps
and 8 g, until the data comes from the controller.

* mii: read BuildRandom's age, gender and race as 32-bit words
IDatabaseService::BuildRandom takes Age, Gender and Race as three
32-bit values. Since the move to the CMIF templates the handler took
the u8 enums directly, so they were unpacked from bytes 0, 1 and 2:
gender and race came from the upper bytes of age and were always 0.
Every random Mii was built male with race 0, whatever was asked.
Nintendo Switch Sports asks for 100 random Miis with age, gender and
race All (3, 2, 3); they were logged as 3, 0, 0 and are now 3, 2, 3.

* shader: lower I2F from signed 8- and 16-bit sources
I2F.F32 with a byte or half-word source was only lowered unsigned.
Bit 74 marks a signed source (as in the I2FP lowering); with it set,
the program was rejected ("native byte-to-float conversion mode").
Mario Tennis Fever's text pixel shaders convert I2F.F32.S16, so its
dialogue boxes and button prompts were drawn without any text.
Pass bit 74 on as Maxwell I2F's signed-source bit (13) for both forms.

* shader: lower guarded USHF, LEA.HI with a constant and G+B TLD
Hyrule Warriors: Age of Imprisonment rejects these after its second
set of cutscenes, and a native macro then loops past its instruction
limit just before the reported crash:
- @upn USHF.R.U32.HI: a uniform shift guarded by a uniform predicate
("native uniform shift mode"). Swap the guard in as the other
uniform-predicated forms do.
- LEA.HI Rd, Ra, c[b][o], RZ, s ("native constant LEA carry mode"):
c + (Ra >> (32 - s)), as the register form.
- TLD.SCR with only G and B ("native texel fetch mode"): TLDS has no
single-register G+B or R+B swizzle, so fetch alpha too, as the
three-channel form, into scratch.

* vk_buffer_cache: don't abort on an unmapped texture buffer
A texture buffer whose address isn't mapped is bound as the null buffer
with PixelFormat::Invalid, and making its view hit "unreachable unknown
format Invalid" in MaxwellToVK::SurfaceFormat. Hyrule Warriors: Age of
Imprisonment (a user's log) and the Yoshi and the Mysterious Book demo
crash there.
Give it a placeholder format; the view covers the null buffer.

Also rejected in Hyrule Warriors: Age of Imprisonment (a user's log):

guard in as ULOP3 does, when it has no carry outputs.
- LDL.LU.S16 ("native local scalar spill mode"): Maxwell LDL/STL take
the same U8/S8/U16/S16 size codes, so pass them on.
Assisted-by: Claude Opus 5.5 (diagnosis, fix and testing)
* shader: lower IMNMX with an immediate wider than 20 bits
Maxwell's IMNMX immediate is a signed 20-bit value, so the lowering
rejected wider ones ("native integer min/max mode"). Yoshi and the
Mysterious Book's demo has IMNMX.U32 R3, R11, 0x1fffffff in a compute
program. Load those into a scratch register and use the register form.

* shader: lower SHF.L.U32.HI with an immediate high word without .W
Only the wrapping (.W) form of SHF.L.U32.HI Rd, RZ, Rb, imm was lowered;
without .W ("native funnel shift immediate mode") the shift clamps, so
32 or more gives 0, as Maxwell SHL without its wrap bit. The Yoshi and
the Mysterious Book demo has SHF.L.U32.HI R26, RZ, R26, 0x1 in a compute
program. Pass bit 75 on as SHL's wrap bit.

* vk_rasterizer: skip draws with a garbage vertex or index count
A draw's first and count can come from memory that a compute program
should have written; when that program is rejected and skipped, they
are whatever was there. Hyrule Warriors: Age of Imprisonment crashed
entering new areas: a quad draw past what fits in an index buffer made
QuadIndexBuffer::UpdateBuffer's CreateBuffer throw out of the GPU
thread, and the process aborted (two crash dumps, same stack).
Skip draws reaching past 16M vertices or indices, with a warning.
Assisted-by: Claude Opus 5.5 (diagnosis, fix and testing)
* shader: lower more forms Hyrule Warriors uses entering new areas
Programs still rejected when Hyrule Warriors: Age of Imprisonment loads
a new area, right before the crash there:
- MOV Rd, URn from any uniform register ("native uniform move source"),
not only UR0-UR15.
- DEPBAR.LE with a scoreboard list (DEPBAR.LE SB0, 0x0, {3,2,1}): a
scoreboard wait, a no-op once lowered like the form already accepted.
- F2I from |Rs| ("native float-to-integer conversion mode"): clear the
sign into a scratch register first.
- LEA Rd, Ra, c[b][o], s without a carry ("native constant LEA carry
mode"): ISCADD (Ra << s) + c.
Assisted-by: Claude Opus 5.5 (diagnosis, fix and testing)
* shader: lower STS with a uniform base and UMOV into any uniform register
Rejected by Hyrule Warriors: Age of Imprisonment during battles:
- STS [URb+offset], Rd (0x988, "unsupported native opcode"): the
uniform base is in bits 64-71 (bit 91 set), the data in bits 32-39;
add it to the address as the LDS form with a uniform base does.
- UMOV URd, imm into UR16 and up ("native uniform immediate move mode"):
write the register the uniform maps to.
Assisted-by: Claude Opus 5.5 (diagnosis, fix and testing)
* shader: lower UMOV URd, URs into any uniform register
Only UR0-UR15 were accepted as the destination ("native uniform move

Adapted from https://git.eden-emu.dev/Franseven/PokeDinner-a-Eglantine-Fork/commit/76df4591a7474c5f775ae4b60eaadd7602804acc. Disabled by default; validate mappings and list bounds before writing.
* diagnostics: measure indirect reset cost
* video_core: wait for queued GPU writers before reading small entries on unmarked pages
With the split GPU thread, the back marks a page GPU-written only when it
runs the work that writes it. When a compute dispatch fills a page for the
first time (Hyrule Warriors: Age of Imprisonment writes each draw's
arguments into small 4-word entries in fresh memory), the front can reach
the entry that reads it before the back ran the dispatch. The page still
looks CPU-only, so the front takes the words as submitted: leftover bytes.
The draw macro then runs with counts in the billions, and later the device
is lost.
Small entries (up to 8 words, the size of such argument blocks) on pages
not marked GPU-written now wait for the compute and copy work sent so far
(WaitForWriters) before the read path is chosen.
Assisted-by: Claude Opus 5.5 (diagnosis, fix and testing)
* buffer_cache: download GPU-written bytes on a page before a CPU write claims it
The memory tracker works in whole pages: a CPU write marks its pages
CPU-modified, which clears their GPU-modified state. GPU-written bytes
elsewhere on those pages stay in gpu_modified_ranges but are never
downloaded (DownloadBufferMemory only visits ranges the tracker still
calls GPU-modified), and the page's next upload sends the stale guest
copy over the host buffer's correct bytes.
Hyrule Warriors: Age of Imprisonment writes small structures next to the
4-word draw arguments its compute dispatches fill in. The read-path flush
then found nothing to download, and the draws read leftover bytes as
vertex counts in the billions (the host buffer held the right values each
time). In fights this ends in a lost device.
WriteMemory now downloads the GPU-written bytes left on the touched pages
(after removing the bytes the CPU wrote) before marking them CPU-modified.
Assisted-by: Claude Opus 5.5 (diagnosis, fix and testing)
* buffer_cache: track the ranges of each pending fence download separately
GPU-modified ranges that download at fences are copied to a staging
buffer when a fence is committed and written to guest memory when it
pops. async_downloads counted the pending ranges in one overlap set, not
per download. A newer download of the same range then stood in for an
older one: the older download's pop found the range pending, wrote its
older bytes, used up the newer download's count and dropped the range
from gpu_modified_ranges; the newer pop found nothing left to write.
Guest memory kept the old bytes, and nothing marked the range for a
download any more.
Hyrule Warriors: Age of Imprisonment rewrites its draw arguments every
frame on pages that download at fences. In fights, draws read the older
bytes as vertex counts in the billions and the device is lost. With
downloads at fences turned off the bad reads stop (0 in a 6.5-minute
fight), and logging showed each bad slot last written by the pop of a
download taken before the slot's latest GPU write.
Each pending download now keeps its own ranges. CPU writes, inline
uploads and DMA copies (ClearDownload) and GPU writes remove what they
overwrite from every download already taken; a pop writes, and drops
from gpu_modified_ranges, only its own remaining ranges. The newer
download, or the next fence, brings the newer bytes.

* vk_scheduler: batch fence submissions on the split GPU thread
Every fence submitted the scheduler's work to the queue. Switch 2
titles make one per compute release: in Hyrule Warriors: Age of
Imprisonment fights about 11,500 fences a second, about 22,000 queue
submissions a second in all, and the Vulkan worker spent over half of
its busy time in vkQueueSubmit while no thread was saturated.
On the split's back, a fence now submits only if the last submission
is older than 500 us; otherwise it goes with the next one. The back
submits a deferred fence before it sleeps waiting for work, so a
deferred fence is never left unsubmitted. Threads other than the back
(the fencing thread) no longer submit to wait for a fence: they wait
until the back has, then for the GPU. EDEN_NX2_FENCE_FLUSH_US sets the
window; 0 submits at every fence as before.
Measured on the same recorded fight (docked, 1600x900), heavy stretches
only: median 31-37 fps in five runs before, 41-44 fps in five runs
after; minimums 29-33 before, 33-38 after. No freezes, skipped draws
or late fences in about ten runs.

* vk_scheduler: also batch command list copies and FlushCommands
With fences batched, Hyrule Warriors: Age of Imprisonment fights still
made about 15,000 queue submissions a second. Counted by calling site:
58% came from the command list page copies made after each compute
dispatch that writes such pages, which the split's front waited for in
only about 5% of cases; 38% from FlushCommands, which SignalFence calls
right after queueing a fence that carries downloads or queries, so the
fence's own deferral was undone at once.
Both now defer like fences (Scheduler::DeferFlush). A thread other than
the split's back that needs a deferred tick submitted, the front reading
a command list copy or the fencing thread, asks the back for it
(Scheduler::WaitSubmitted, GpuSplit::RequestIdleHook): the back checks
for the request between ring entries and before it sleeps, instead of
the waiter polling until the back's next submission.
Same recorded fight as the previous commit (docked, 1600x900), heavy
stretches only: queue submissions about 22,000 a second before both
commits, 1,100 after; median 42 fps with fences batched, 46-49 with
this; minimums 35-40 before, 43-45 after. No freezes, skipped draws or
late submissions in six runs.

The batch merge of zortos293#413 and zortos293#465 left uses_async_copy unused, which GCC's -Werror rejects
and broke the non-PGO Linux builds. The barrier is only needed when the program issues
LDGSTS copies, as in zortos293#465.
* dma_pusher: keep command list snapshots across semaphore waits
Hyrule Warriors: Age of Imprisonment froze in fights every few minutes:
a burst of methods on an unbound subchannel, garbage QMDs, then a
channel waiting forever on a semaphore whose release was never parsed.
The entries parsed just before held the next frame's commands: the game
had already refilled that command ring, and the entries were read from
memory instead of their submit-time snapshot.
Two causes:
- Puller::ResumeAcquire counted a resume on every call, also with no
acquire pending, and DmaPusher::Step calls it before every entry. The
suspension count, which is odd while a channel waits, was odd at
random, so about half of all entries took the "copied during a
suspension" path and read memory.
- Lists that really did wait behind an acquire read memory, because a
game may write their commands after submitting them, before it
releases the acquire. Read at parse time, they could already hold a
later frame's commands.
ResumeAcquire now counts only a resume from a suspension. When a channel
resumes, the lists queued behind the acquire are copied again: their
commands are written by then, and the memory is not reused yet. A list
that arrives later with a copy taken during the suspension is copied
again when it is queued. EDEN_NX2_RESNAPSHOT=0 turns the copying off.
A check comparing each parsed entry with its snapshot (local debug
build) found 29 entries in a row differing from word 0 before the
freeze. With the copy at resume alone: no freeze, garbage method or
garbage QMD in six runs through the same fight, where it had happened in
about one run in four. With the counting fix as well, every entry was
parsed from its snapshot in a short run (more runs pending).

gender and race came from the upper bytes of age and were always 0.
Every random Mii was built male with race 0, whatever was asked.
Nintendo Switch Sports asks for 100 random Miis with age, gender and
race All (3, 2, 3); they were logged as 3, 0, 0 and are now 3, 2, 3.

* vk_scheduler: keep waiting for a deferred submission instead of giving up
A fence or command list copy whose submission the split's back deferred
was waited for at most two seconds; after that the fencing thread
treated the fence as done and ran its downloads and operations before
the GPU had the work. The back can spend seconds on one entry (a large
shader's translation), so that could happen without anything wrong.
Scheduler::WaitSubmitted now waits until the back submits, asking it
again and logging every two seconds. It returns false only when the
back thread is not running (GpuSplit::BackRunning), and then the caller
submits the work itself, since nothing else uses the scheduler.
There is no wait cycle to break: the fencing thread waits outside the
fence manager's lock, and the back never waits for the fencing thread.

Port of f992933 (Lichii zortos293#465) from origin/nx2, verbatim (one trivial
conflict in vk_graphics_pipeline.h resolved by taking the upstream block).
A Switch 2 draw whose graphics pipeline is still building waits for the
whole driver build, so a cold pipeline holds the draw (measured up to
14.6 s of draws held per 10 s window elsewhere). native_async_draws
(Wait/Bounded/Skip, default Wait = today's behaviour) plus
native_pipeline_wait_ms (8 ms per frame) let Bounded wait up to the
budget per frame and then skip the draw. Decisions are pure and covered
by the Catch2 tests in native_pending_policy.cpp.
47 upstream commits since build-94, among them HMMA on VK_KHR_cooperative_matrix
(zortos293#582, zortos293#583, zortos293#657), compute-emulated task/mesh pipelines (zortos293#569), the bounded wait
for unbuilt Switch 2 pipelines (zortos293#465) and Switch 2 GPU page table sizing (zortos293#333).
Conflicts:
- emit_spirv_tensor.cpp: build-117's version (with the cooperative matrix path),
plus the fork's quad-broadcast A operand and fp16 rounding (4d3d244) and the
Qualcomm software HMMA change (3ca6acf). Tests take build-117's version.
- nx2_audio_device_manager.h: PurgeStream keeps both purges, upstream's for input
streams and the fork's for output streams.
- vk_rasterizer.cpp: the fork's Ocarina mesh skip on hanging-mesh GPUs, now only
for native mesh draws, then build-117's mesh emulation.
- vk_texture_cache.cpp: build-117's retrying ASTC decode image, sized to the
fork's layer chunk.
- kepler_compute.h, gpu_thread.cpp: both sides kept.

Scenario: Switch 2 (native Turing) draws whose graphics pipeline is still
building are never skipped, so the GPU waits for the driver build. On an
RX 6700 XT (Zelda OoT Switch 2) the log showed up to 14656 ms of draws held
in a 10 s window and single builds of 16.7 s.
Add native_async_draws (Wait, Bounded, Skip; default Wait keeps the current
behavior) and native_pipeline_wait_ms (per-frame budget, default 8 ms), both
in the Qt advanced graphics settings. Bounded does a timed condition-variable
wait on the pipeline build up to the per-frame budget, reset in
PipelineCache::TickFrame, then follows Skip. EDEN_NX2_ASYNC_DISCARD=1 still
forces Skip. The decision is a pure function covered by a Catch2 test.
Measured with Bounded at 8 ms on the same machine: at most 229 ms of draws
held per 10 s window, 10 to 614 ms of bounded wait per window, and a
one-frame flash when the budget runs out.

With asynchronous shaders on, a Switch 2 (native Turing) draw whose graphics pipeline is still building is never skipped:
CanDiscardPendingDrawreturnsfalsefor native draws, so the GPU thread waits for the driver build. In Ocarina of Time (0400486024DEC000) on an RX 6700 XT, the existing 10 s runtime report showed up to 14,656 ms of draws held for unbuilt pipelines in one 10 s window, with single builds of up to 16.7 s. In game, the frame rate falls to 0 to 7 FPS the first time a new area is drawn (the forest, cutscenes). Until now the only way out wasEDEN_NX2_ASYNC_DISCARD=1, which skips every pending draw and can leave effects missing.This adds a middle ground: wait, but only up to a per-frame budget. The default is unchanged.
Changes
native_async_draws(Graphics > Advanced, per game), enumNativeAsyncDraws:Wait(default): the current behaviour.Bounded: the draw waits for its pipeline, up to what is left of a per-frame budget. Once the frame's budget is spent, the frame's remaining unbuilt draws are skipped as withSkip.Skip: pending native draws are skipped, the same asEDEN_NX2_ASYNC_DISCARD=1.native_pipeline_wait_ms(1 to 100, default 8): the per-frame budget forBounded.EDEN_NX2_ASYNC_DISCARD=1still forcesSkip, so existing setups behave the same.PipelineBuild::WaitFor(std::chrono::microseconds)inpipeline_build.h: a timed wait on the build's existing mutex and condition variable (wait_foroncomplete). It returns whether the build finished.GraphicsPipeline::WaitBuilt(timeout)wraps it.DecideNativePending(mode, can_discard, budget_left_us)inasync_draw_policy.h: a pureconstexprfunction returningWait,WaitTimedorSkip. It is the only place the decision is made, and it is covered bysrc/tests/video_core/native_pending_policy.cpp([native_pending]).PipelineCache. Only the GPU thread touches it, andPipelineCache::TickFrameresets it each frame.Bounded pipeline wait: X ms spent in the last 10 s (budget N ms per frame)shows what the mode costs, readable from a user log.Trade-off.
Boundedswaps a long stall for a short one. In the worst case a draw is missing for one frame, which shows as a flash. That is whyWaitstays the default.Related. #408 reduces how many pipelines get built mid-game. #411 warms pipelines up ahead of time. This PR changes what a draw does while a pipeline is still building, so it stacks with both. It touches the same stutter as #416 (GPU-thread pipeline stalls in Ocarina of Time) and #426 (why asynchronous shaders don't skip native draws), and the new
Bounded pipeline waitlog line is a small piece of the compile diagnostics asked for in #405.Testing
Setup. Windows 11, Ryzen 7 5700X, RX 6700 XT (AMD proprietary driver), 32 GB. Handheld, resolution 1x, FSR 1, FXAA, GPU accuracy Fast, ASTC recompression BC3, async shaders on,

This PR does not touch that; #408 targets it.
