Since #1454, a libSceLibcInternal import that no native library exports
on Windows falls back to the title's own libc.prx. The loader shim that
ps5-native-app-boilerplate builds into homebrew titles exports 1874
functions at three addresses whose code is `xor eax, eax; ret` or
`pxor xmm0, xmm0; xor eax, eax; ret`. Such an import then binds to a
function that returns 0, and the title starts instead of stopping with
`unresolved ELF import`.
The Windows guest module writer records the exported functions whose
code is one of these two sequences, and the entry stub leaves the guest
libc.prx out of the search for those names. A guest export with code of
its own still provides a missing libSceLibcInternal function, and native
libraries keep their priority.
A draw or dispatch whose shaders have guarded descriptor slots (or a rect
list) but no BDA table gets a fault buffer, and with it NeedsCompletion(),
which kept its resources out of the resource cache, and NeverReusable
skipped the cache lookup for it. In PPSA36082 nearly every draw in the hub
is such a build, so the cache served none of them.
Such an object has no table to revalidate, no stores through BDA and no
copied writes, so it is now reusable. Each use of a reused object checks
the fault record when its batch completes (CheckFaults) instead of
running the once-only write-back; draw recipes over such a template
register the same check, and dispatch recipes still skip templates with
completion work. NeverReusable now refuses what noteReusable refuses: a
BDA table, or a fault buffer with APS5_LOOP_GUARD set (its fault resets
the buffer).

Extend the independently Windows-tested WAIT_REG_MEM candidate 056534a9 with a focused shutdown regression. Keep labels unsatisfied on graphics and two compute queues beyond the configured diagnostic, then require prompt shutdown without executing the commands or pending submissions behind those waits.
The production cancellation path already calls CheckFailure/checkStopping and catches ProcessShutdown in the worker; no runtime behavior is changed. This test does not explicitly open a Vulkan device.
Validation: Linux/GCC 13.3, C++20, -O2 -Wall -Wextra -Werror object compilation against the production headers; conventions and whitespace pass. CMake configuration, runtime linking and execution, and native Windows execution were not performed in this environment. Runtime verification remains pending. Depends on the persistent-wait candidate for #2832/#2985; maintainer policy approval is pending.
AI-assisted: yes.
With the f32 denormal field of FLOAT_MODE set to keep, v_ldexp_f32
flushed subnormal inputs and results to zero. Keep subnormal inputs and
round a result that lands in the subnormal range in the f32 round mode
of FLOAT_MODE. An overflow follows the round mode as well, with or
without denormals kept: the largest finite value instead of infinity
when the mode rounds that sign toward zero. This matches RDNA2
(gfx1036) on 2163 rows in each round mode. Denormal modes 1 and 2 now
throw.

Unsubscribe an event queue from the output mode events that
sceVideoOutAddOutputModeEvent registers, the same way the flip and
vblank events are removed. Deleting a registration that does not exist
succeeds, and a null queue or an invalid handle throws.

The bundled libc.prx of PPSA21703 calls sceKernelGetModuleInfoFromAddr
with a 0x1A8-byte stack buffer and never sets st_size, so the field holds
whatever was on the stack (983040 in one run) and the call threw. The
console cannot require the field on input. The full size is still
written back. The flags check is unchanged.

vkQuake's NGG culling vertex shaders load only the vertex ID
(SPI_SHADER_PGM_RSRC2_GS ES_VGPR_COMP_CNT 0), and DecodeShaderStages still
required 3 for a program routed to the mesh path. The merged ES inputs keep
their positions whatever the count, and the mesh entry loads all of them,
so the count is now checked only for real geometry programs, as the GS
VGPR count already was.
