Main's Linux job fails since #1028 and #1714: guest_video_out_resolution_status aborts when SDL's offscreen
driver has no Vulkan window, and check_skips.py rejects the skips of guest_video_out_wqhd_detection and the
flip tests because "no display" is not among the device limitations it accepts.
The resolution status test now skips with code 77 like its wqhd sibling, the flip tests print the same skip
reason, and check_skips.py accepts "no display" as a device limitation. ANYPS5_REQUIRE_DISPLAY still turns
the skip into a failure.
AI-assisted: yes. Full current-main project build passed. Seven focused Windows tests pass; four shader tests also pass in full and none optimization modes with actual Vulkan execution required. Updated Linux and title runs remain pending.
gmtime, localtime, mktime, strftime and asctime took and returned the
host std::tm. The guest's FreeBSD tm has tm_gmtoff and tm_zone after the
nine calendar fields, so on Windows, where std::tm is 36 bytes, a title
reading those fields read past the thread-local result, and gmtime_s left
them unwritten. Windows gmtime_s also accepts only 1969-12-31 12:00 to
3001-01-19 21:59 UTC, where the guest libc converts any time.
Convert through a GuestTm with the guest layout on both hosts. Compute
the UTC fields from the day count, so every time whose year fits an int
converts, and on Windows take the local offset and zone name from the
CRT. gmtime reports the zone as UTC like the guest libc. localtime and
mktime keep the CRT's range on Windows; recorded in TechnicalDebt.

As requested in review: a failed sceKernelGetModuleInfoFromAddr no longer
reports an empty answer. Adds a failure test (symbol interposition) and
extends the metadata test (EH record walk, terminator, no-header DSO).

A title that ships its own libc.prx unwinds C++ exceptions with that
libc's libunwind, which asks sceKernelGetModuleInfoForUnwind where each
frame's eh_frame is. On Linux the call always reported no tables, so
no C++ exception thrown in guest code could be caught. For the main
executable and .guest.prx images, report the PT_GNU_EH_FRAME tables
that sceKernelGetModuleInfoFromAddr finds, as Windows does from
.ehmeta. Other host images still report none.

CB_COLOR_INFO format 6 (COLOR_10_11_11) with NUMBER_UNORM threw in
DecodeColorFormat: Vulkan has only the B10G11R11 float format. Such a
target now renders into an R32_UINT attachment in the layout of
format-30 images (unorm11 R and G in bits 0-21, unorm10 B in bits
22-31), so later image loads of the surface read the same words.
The target format is draw state, so the packing is a specialization of
the registered pixel shader: every float MRT export also computes the
packed word (EmitFormatStoreComponent) behind specialization constant
ExportPackingBase + target, and the specialized module turns a packed
target's output into a uint4 that ValidateShaders expects. The new
request field targetExportPacking is in the module key, the result memo,
the draw key and the serialized request (version 14). Blending, partial
RGB writes, UNORM16/SNORM16/UINT16 exports, DCC and ROUND_MODE throw.
agc_driver_pending_exact_surface writes mip 0 of a 2-mip 256x256 surface and then a 1-mip surface at the same address. The chain's mip 0 lies past the 1-mip surface's bytes, so both images stay pending, the chain first. A lookup of the 1-mip size must return the 1-mip image, and with only the chain pending it must still return the chain. On main the first lookup returns the chain.
Winsock fails send, sendto and sendmsg on a socket shut down for writing
with WSAESHUTDOWN, which neither Windows error map handled, so libkernel
and libSceNet reported EIO. FreeBSD reports EPIPE there, and the Linux
maps already translate the host's EPIPE to 32. Map WSAESHUTDOWN to 32
in both.
agc_driver_graphics registers a D32 and a D16 surface on a mock device and looks up views at their addresses. Views of the surface's own extent in R32F or R16, and T#s that read the raw depth bits, sample the depth plane; a view of another extent, a 2D array view of another extent, an R11G11B10 view, an R32 uint view without a depth layout and an R32F view of a D16 surface return null and take the ordinary texture path. On main the first of these throws in DepthSurface::Sampled.
Measured on a PS5 (firmware 13.60) through dlopen of
libSceVideoOut.sprx on a handle the payload opened.
sceVideoOutInitializeOutputOptions writes 0xFF to byte 2 of the 64-byte
options and returns INVALID_ADDRESS for a null pointer.
sceVideoOutIsOutputSupported checks the handle, then the reserved
arguments, then the mode, then the options. It never answers 0: a mode
the display lacks returns UNSUPPORTED_OUTPUT_MODE, and a value that is
not a mode returns 0x8029001E. Options must keep the initialized words,
except word 3.

Fill takes either info struct, so sceKernelGetModuleInfo reports the
name and segments sceKernelGetModuleInfoFromAddr reports for the same
image, on Linux and Windows.
A sampler with FORCE_DEGAMMA (S# word 0 bit 20) threw at decode, so
every dispatch or draw sampling through one was skipped.
DecodeSamplerResource now records the bit, but accepts it only for a
caller that pairs the sampler with its images. The direct sampler
binding does, and RequireDegammaFormat checks each sampled image
against its paired samplers: only already sRGB formats (8, 8_8 and
8_8_8_8 SRGB, BC1, BC2, BC3 and BC7 SRGB) pass, decoded once, as
shadPS4 (PS4) models it. Other textures and unpaired decodes still
throw; gfx10 behaviour is not measured.
On Windows, nanosleep and this_thread::sleep_for/sleep_until go
through winpthreads, which ends a wait on a 15.6 ms GetTickCount64
step. Blocking sceAudioOutOutput and sceAudioOut2ContextPush calls
returned in bursts about every 16 ms, a blocking sceAudio3dPortPush
ran at about 68 % of real time, and sceAudioInInput without a device
woke anywhere from 1 ms to 31 ms apart. They now sleep with
PreciseSleepUs or the new PreciseSleepUntil.

sigprocmask keeps the first word of the title's set as it is, where
FreeBSD keeps signal n at bit n - 1 (_SIG_BIT), but Dispatch tested bit
n. A title that blocked SIGTERM with a FreeBSD-built set (bit 14) was
not protected, and a set with bit 15 blocked SIGTERM instead of SIGURG.
Dispatch now tests bit n - 1; the stored mask and the set returned by
sigprocmask are unchanged.

The AMD Windows driver returns 1 for a NaN operand when any float form
of ordered not-equal feeds a ballot on a 32-wide subgroup, which is how
e32 compares are read in wave32. FPOrdNotEqual32 is now emitted as an
unordered not-equal with both operands checked for NaN on their bits,
which gives the same result for every input.
