Use an SRW lock and native Windows condition variable for epoll waits, preserving the shared handle lifecycle. This avoids the scheduler-tick overshoot measured with std::condition_variable on Windows.
Suggested-by: winstrex
Deathloop (PPSA01670) imports sceHttpAbortWaitRequest; Planet Coaster
(PPSA01736) and Palworld import sceHttpWaitRequest.
Epoll handles are kept in a registry with an abort flag, a destroyed flag
and a condition variable. A wait with a negative timeout blocks until
sceHttpAbortWaitRequest, sceHttpDestroyEpoll or the sceHttpTerm of the
last context wakes it; a bounded wait still returns 0 events. An abort
stays set and makes every later wait return SCE_HTTP_ERROR_ABORTED
(0x80431080); a wait woken by destroy or term returns 0 events.
sceHttpDestroyEpoll no longer frees a handle a waiter is blocked on.
sceHttpInit registers its context, and the epoll calls and sceHttpTerm
return BEFORE_INIT without a live context and INVALID_ID for an unknown
context or handle.

On macOS, GuestWriteWatchCollectFresh reported nothing and returned true, so
MarkWritten took pages no collection had armed yet for clean, and they stayed
writable without being tracked. GuestWriteWatchCollectArmed was a full collect,
which also took those pages.
Pages now carry a fresh bit from registration until a collection takes them, as
the Linux watch keeps its fresh ranges: CollectFresh reports and arms only fresh
pages, CollectArmed skips them, and Collect takes both. Protection changes, host
writes and faults keep the bit.
The write_watch fresh and armed tests check both collections.
The call was an unimplemented stub. It now writes syllable state 0 and
returns OK for every character outside the Thai block, where a PS4
firmware 11.00 libSceFont measures 1, 3 or 4; Thai characters throw as
not implemented. A null character or result returns
SCE_FONT_ERROR_INVALID_PARAMETER, and a null character writes 0 to a
non-null result, as measured. The signature follows SharpProspero.

asinf returned 0xffc00000 (errno 33) for 2.0 (0x40000000), where FreeBSD
lib/msun/src/math.h returns 0xffc00000 (errno 0).
It now returns the FreeBSD result for that case. A guest test covers it
and fails on main.

The second argument is an out pointer to the writing's letter step, as
KytyPS5 and the SharpProspero bindings declare it. It was filled as a
letter step struct, which wrote 64 bytes over the caller's 8-byte
pointer. The letter step now lives in the writing and the call stores
its address, or null when there is no current step.

FreeBSD removes or renames a file that is still open; the descriptor stays usable. _wopen opens without FILE_SHARE_DELETE, so sceKernelUnlink returned EACCES and rename failed while the guest held a descriptor. sceKernelOpen now opens through CreateFileW with delete sharing and keeps the flag, mode and error mapping of _wopen.

The AMM ranges were reserved at the last 64 GiB of the guest arena and
the reservation threw when that window was not free. On Windows the
stacks of the threads that exist before the arena is reserved (the main
thread and the loader's workers) are placed at random addresses and are
left in the arena as host regions; when one fell in the last 64 GiB, the
first AMM use threw "fixed guest mapping ... overlaps a host region in
the guest arena". Reserve the highest free 64 GiB window instead: the
last 64 GiB when it is free, and the window just below an occupied part
of it otherwise.
The decoder throws "VOP3 source modifiers are not implemented" for
VOP3-encoded float compares (v_cmp_*_f16/f32/f64) that set the clamp
bit, so shaders using them fail to compile.
On RDNA2 hardware the clamp bit does not change the result of a float
compare: the measured results with and without it are the same. The
decoder now accepts the bit on float compares; clamp on other carry-out
and scalar-destination opcodes still throws.

The assembler encodes the unused third source of the VOP3-encoded
interpolation forms as the inline constant 0 (src2 = 0x80, bit 25 of the
second word), which the decoder refused. Accept that encoding and refuse
any other third source. The decode test now uses the assembler words for
every accepted form and keeps the refusals one field away from a valid
word.
Both open the same SDL capture port as sceAudioInOpen, so Input,
GetSilentState and Close work on their handles. HqOpen accepts only a
128-sample grain at 48 kHz (SharpProspero, KytyPS5); AsyncOpen returns
INVALID_SIZE above 384 samples (SharpProspero). Values the sources
disagree on throw. Format 0x10 still throws: only KytyPS5 accepts it.
Imported by FMOD-based titles, The Smurfs Dreams (PPSA21607) and Astro
Bot (PPSA21564); Ghost of Yotei (PPSA26344) calls sceAudioInOpen.

Root ignores the file mode, so truncating a file with only the owner
read bit succeeds and guest_truncate aborted when the suite ran as root,
as it does in containers. The read-only cases now run only for other
users and the test says on stderr when it skips them.

sceHttp2DeleteRequest erased the request's completion queue, but
sceHttp2DeleteTemplate and sceHttp2Term removed descendant request
handles through ReleaseOwnedHandles without clearing their completion
queues. A request that completed asynchronously before its template or
context was deleted kept a stale completion that sceHttp2WaitAsync could
still consume.
ReleaseOwnedHandles now returns every transitively removed handle id, and
DeleteTemplate and Term erase the completion queue of each removed
request. CompleteAsync validates that the request is live while holding
the handle lock and inserts the completion under it, so a send that races
a deletion either returns the invalid-id error without queuing or is
erased by the deletion; a completion is no longer re-created after a
deletion returns. The only lock nesting stays handles before completions,
and no mutex is held while the user event is triggered.
GuestHttp2 covers a queued completion before sceHttp2DeleteTemplate and
before sceHttp2Term: the completion is no longer consumable, a late send
returns the invalid-id error without queuing, and the removed handles are
rejected.
Ubuntu's GCC links with --as-needed, so a test that calls nothing in
libc.prx directly dropped it from DT_NEEDED and satisfied the prx
libraries' __cxa_* and __gxx_personality_v0 references from the static
libstdc++ instead. Those copies interpose libc.prx's, so exceptions
thrown inside the prx libraries were searched by libgcc and resumed by
the guest unwinder, which aborted guest_kernel_stack_protect. libc now
propagates to every consumer of a prx with --no-as-needed on Linux.

An SDL controller sets the L2/R2 bit whenever its trigger axis is above
zero, and BuildData then reported 255 for any set bit, so a partly
pressed trigger read as fully pressed. Report the analog value whenever
there is one; 255 remains for an injected press and for a bit without
an analog value.

DecodeState bound the depth surface whenever DB_DEPTH_CONTROL enabled a
depth, stencil or depth bounds test and either plane was valid. A stencil
test beside a depth-only surface (DB_STENCIL_INFO format invalid, depth
test off) tests nothing, but the surface was still attached and the
render extent was clamped to it. A draw into a 1920x1080 target with a
960x540 depth surface left bound then covered only the top-left quarter.
A test whose plane is present but invalid no longer binds the surface.
Such a draw renders without a depth attachment, as it already does when
both planes are invalid. DrawRejection follows the same rule.
PPSA03490 (Demon Slayer) imports sceRudpGetMaxSegmentSize, sceRudpProcessEvents, sceRudpNetFlush and sceRudpNetReceived, which no library exports. The first three answer by the library's initialised state; sceRudpNetReceived is declared without an implementation because its signature is unknown. Adds one test and TechnicalDebt entries.

On the AMD Windows driver 32.0.13058.8001 (Radeon 860M), a NaN compared
less than +infinity, or +infinity greater than a NaN, gives 1 when the
infinity reaches the shader as a constant, as in
agc_driver_f32_compare_constant's register operand case (#3536). The
same driver returns 1 for a NaN in an ordered not-equal (#825), which is
presumably what its compiler turns these compares into. FPOrdLessThan32
and FPOrdGreaterThan32 now AND their result with the integer NaN check
FPOrdNotEqual32 already uses, which gives the same result for every
input.

SceErrorFromErrno in the libkernel file functions passed host errno
values 1-34 through and turned every other value into EIO. Linux numbers
EAGAIN 11, which is FreeBSD's EDEADLK, so a read from an empty
non-blocking pipe returned SCE_KERNEL_ERROR_EDEADLK, and ENAMETOOLONG,
ELOOP, ENOTEMPTY, EDQUOT and EOVERFLOW, whose host values differ from
FreeBSD's, all became EIO.
Map those host values to the guest's FreeBSD numbers, as
SceIoErrorFromErrno in Open.cpp already does for EAGAIN, EDEADLK,
EDQUOT and EOVERFLOW. The guest constants the callers pass are all at
most 34 and never 11, or GUEST_ENOTEMPTY, so they are unchanged.

Clang's PS4 and PS5 targets set the default new alignment and the suitable
alignment to 32 bytes, so PS5 code may store to a fresh mspace block with
32-byte-aligned AVX instructions, as the guest heap already allows since
#1621. The mspace allocator aligned blocks to 16 bytes only. Every mspace
allocation is now aligned to at least 32 bytes.

RADV (Mesa 26.2.4, GFX12) updates the user SGPR count and draw-id flag
it uses for a mesh dispatch only when the bound mesh shader has the
grid-size/draw-id slot. A mesh shader reading neither NumWorkgroups nor
DrawIndex keeps the previous vertex pipeline's values: the dispatch
opens a 3-register SET_SH_REG, writes one value, and the CP parses the
following DISPATCH_MESH_DIRECT as register data. The gfx ring then
times out and the GPU is reset with VRAM lost.
Kena: Bridge of Spirits (PPSA01802) hits this on its layered volume
draws, which interleave with vertex draws in one command buffer.
Confirmed with RADV_DEBUG=hang (the dispatch header shows up as
SPI_SHADER_USER_DATA_GS_4) and the CP header history in the amdgpu
devcoredump.
Every mesh shader now loads NumWorkgroups.x and sets zero vertices
when it is 0, which no dispatch produces, so RADV gives it the
grid-size slot and writes as many values as it announces.

Cover 16 paths with long leaves, exact-fit and overlong directory results, repeated separators, input preservation and guest errno. The regression reports 12 failures on unchanged main and passes with the accompanying fix.
AI-assisted: yes
Find the directory component before checking the result buffer limit, matching FreeBSD 11.4. Preserve input and guest errno on success; overlong directory results still report ENAMETOOLONG.
AI-assisted: yes
ValueClear constructs a Value, then calls the Value(const Object&)
constructor on the same object. The constructor allocates a new node and
overwrites the pointer, so the first node (56 bytes) is never freed.
LeakSanitizer reports it; destroy the value first.

PPSA15246 (Teardown) imports both from the module-named libSceCesCs-module and
stops at the loader without them. Cp1251 joins Cp1252 in sceCesSbcToUtf8 and
sceCesUtf8ToSbc; the context initializer succeeds without storing anything
because its layout is unknown (listed in TechnicalDebt.md).

A pixel input whose SPI_PS_INPUT_CNTL offset names a parameter the
previous stage does not export failed validation ("graphics interfaces
disagree"), so the draw threw. No export writes that parameter slot for
the draw. radeonsi programs a pixel input without a matching vertex
output as OFFSET 0x20 with DEFAULT_VAL 0, so that it reads (0, 0, 0, 0)
(SI_PS_INPUT_CNTL_UNUSED in si_shader.h, applied in si_shader.c), and
rect-list draws already pass zero for such inputs.
Before the pixel stage of a draw is prepared, inputs that read a
parameter the previous stage's program does not export now read zero:
OFFSET bit 5 is set, DEFAULT_VAL and FLAT_SHADE are cleared, and an FP16
input also reads zero in its high half (USE_DEFAULT_ATTR1 set,
DEFAULT_VAL_ATTR1 cleared). Inputs that already read a default value
are unchanged.
Fixes#2975.
fmod set errno (33) for 1.0, 0.0. FreeBSD msun never sets errno and
reports errors through floating-point exceptions only, so errno is now
saved and restored around the host call.

Seed each iteration-selection update from its first eligible successor
instead of rebuilding and intersecting the universe of block IDs.
Reuse the existing in-place intersection and sorted-insertion helpers
while preserving the original empty-successor and fixed-point behavior.
Keep a cache-neutral switch for same-binary output and timing comparisons.
Run the existing structurizer and control-flow fixtures in a separate
process with this optimization disabled as well as in their default mode.
Publish Windows cache entries with the POSIX rename operation so an
open delete-sharing reader keeps its original file after replacement.
Close the rename handle before returning and retain the existing
fallback only when the extended operation is unsupported.
Exercise old and new reader contents, deletion lifetime and temporary
file cleanup in the registered disk-cache regression on both platforms.
The resolved-dispatch map was a nontrivial thread_local object.
MinGW can run its destructor after emutls frees the backing storage,
causing an access violation when a queue worker exits.
Use the existing ThreadOwned helper to destroy the heap-owned map
through its pthread key while keeping a trivial TLS pointer.
Reject FATAL output in both draw-cache test modes so a background
shutdown failure cannot pass only because the process returns zero.
