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.
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.

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.
EVO-PLAYER (PPSA99039) v0.11.0 stops at sigaction once its earlier
imports resolve: it installs a crash handler for SIGSEGV, SIGBUS and
SIGABRT and a quit handler for SIGTERM, SIGINT and SIGHUP at start-up.
sigaction records the handler, flags and mask of signals 1 to 128 and
reports them back, with FreeBSD's EINVAL cases. signal shares the table
and records SA_RESTART, as FreeBSD's libc does. Plain handlers on the
signals signal already delivers run as signal handlers do; SA_SIGINFO
handlers and other signals are recorded only, and raise of such a
signal throws.

Each Windows AIO request is an overlapped ReadFile/WriteFile at the
request's offset, which on a synchronous handle also moves the
descriptor's file pointer; on the console AIO transfers leave it alone.
The requests now go through the positioned path sceKernelPread and
sceKernelPwrite use (NativePositioned in Stdio.cpp, exposed as
NativePositioned_nid_no_patch), which restores the pointer afterwards.
Negative offsets still fail with EINVAL before the transfer.
GuestAio sets the offset to 2 before a write batch and checks it is
still 2 after. TechnicalDebt records that a concurrent read or write on
the same descriptor can see the moved pointer in between, as for the
pread family.

A use of the packed ancillary VGPR other than a constant field extract (the word passed through a
select before its sample number is extracted) reads the word rebuilt from the sample number (bit 8)
and the render target index (bit 16). Extracts of other bits straight from the word stay refused, and
the refusal now names the uses.

Keeps both new TechnicalDebt entries: this branch's note that a raise
can still reenter host code it interrupted, and #2107's sigaltstack note.
