The fchdir entry still said FreeBSD's search-permission check was not
modelled, although it has run on Linux since 0e4d94ce3 and now runs on
every host but Windows.
ARCHITECTURE.md and the debt entry describe how imports under 1 MiB are
settled without waiting and return to the write watch, which the debt
entry listed as not implemented.
A sparse heap mirror, made for a heap with uncommitted pages, is
refreshed from the write watch through its committed pieces. The check
that a reused heap mirror's range is still watched covered the heap
mirrors acquireMirror reuses and the cached space's heap runs, not
sparse ones: once a committed piece left the watch, refreshSparseMirror
threw "a sparse heap mirror's range is no longer write-watched" from
acquireMirror's reuse and from a cache hit's sparse refresh.
refreshSparseMirror now returns false when a piece is no longer
watched. Both callers already take false as not reusable: acquireMirror
makes the mirror again, finds the range unwatched, drops the stale
mirror and leaves the range to a copy, and a cache hit gives up the
cached space.
agc_sparse_heap_mirror_unwatch mirrors a 1 MiB reservation with 256 KiB
committed, takes one committed block off the write watch and stores new
bytes there from the CPU; the next build must not reuse the mirror and
must serve the new bytes. agc_sparse_heap_mirror_unwatch_no_space_cache
runs the same without the address-space cache. Without the fix both
throw. They are registered on Linux; the Windows path uses the guest
arena as the existing sparse heap test does and has not run on Windows.
kevent threw for any descriptor that is not a guest socket. The read end
of a pipe now gets the descriptor knote, following FreeBSD 11's
filt_piperead: data is the number of buffered bytes and EV_EOF is set
once the write end is closed. GuestSockets::Ready falls back to the new
PipeReadState for a descriptor that is not a socket, and WaitAny waits on
the pipe with ppoll on Linux or in 1 ms WSAPoll slices on Windows, only
when the queue holds a pipe. On Windows the equeue waker now starts
Winsock itself, since a queue can wait on a pipe before any socket exists.
A heap mirror is refreshed from the write watch. acquireMirror checked
the watch only when it made a mirror and reused an existing one as it
was. Once part of the range left the watch, the next address-based build
threw "a heap mirror's range is no longer write-watched" from the
refresh, and a build served from the address-space cache threw the same
from its heap runs. A range leaves the watch for good when a host import
that does not keep the watch covers it: on Windows a direct import of
private memory that is not settled (below the 1 MiB settle floor, or any
when imports cannot be settled), elsewhere any import while imports are
compared.
A heap mirror now records the unwatch serial at which its range was last
seen fully watched. Its reuse, and a cache hit over it, compare that
serial with GuestMemory::UnwatchSerial and look at the watch again only
when a range has left it since. A mirror whose range is no longer
watched is not reused, the cache is not taken (before its imports are
stamped), and the pass plans the range again: an import if the budget
allows, else a copy. A refused heap mirror also drops the registry's
stale one, whose buffer would stay allocated otherwise.
sceSysmoduleIsLoaded, sceSysmoduleLoadModule and sceSysmoduleUnloadModule
return success for an id missing from the module table, because titles that
load or unload such an id aborted otherwise (b4db9fdd6, a2520aa07). Nothing
tested or recorded it, and two commented-out throws were left in the code.
Remove the commented-out throws, list the three functions under Silent stubs
in the library's technical debt file, and test that unknown ids succeed
without changing state while the internal variants still throw.

Since ab3e92605 the entry stub gives each missing standard handle
anyps5.log beside the executable, and the crash report writes to the
standard error handle, so it reaches the log too. The entry now records
only what is still lost: the stub's errors about the executable path or
about waiting for the previous LoadExec process, written before the log
is opened, and output to the missing handles when the log cannot be
created.

A geometry program with VGT_GS_OUT_PRIM_TYPE 1 was refused as an
unsupported output assembly. Each primitive export of an NGG line-strip
program is one line whose indices are packed like a triangle's, so the
mesh module now declares OutputLinesEXT with PrimitiveLineIndicesEXT for
it. A subgroup gets VGT_GS_MAX_VERT_OUT - 1 lines per input primitive and
at least GE_MAX_OUTPUT_PER_SUBGROUP line slots; fast launch keeps using
PRIM_AMP_FACTOR. The output size is part of the cache, draw, validation
and pipeline keys, and the request serialization version becomes 31.
Triangle-strip geometry is unchanged.

AnyPS5 exports some libkernel functions, such as __error, from
libc.prx, which libkernel.prx links. On Linux they resolve through that
dependency. On Windows, the import stubs search only the listed
modules, and libc.prx was listed only when libSceLibcInternal.prx was
needed. A PS4 homebrew that needs libkernel.prx but no C library (the
OpenOrbis graphics sample) failed with "unresolved ELF import
9BcDykPmo1I". libc.prx is now also listed when libkernel.prx is needed.
PS5 executables need libSceLibcInternal.prx and convert unchanged.
sceImeDialogInit wrote "Slayer" into an empty text buffer and the
dialog finished on the second status poll, so a title never got text
from the user: ProsperoRadio's search typed "Slayer" by itself and
found no station.
The dialog now runs until the user answers on the host keyboard, the
way #4756 made sceImeOpen's panel-less IME take it. While no IME panel
is open, libSceIme hands the game window's text and editing keys to
a sink that the dialog registers. Typing edits the text up to
maxTextLength without splitting a surrogate pair, Enter writes it to
the title's buffer and finishes with end status 0, and Escape finishes
with 1. Abort still finishes with 2. A second Init reports busy, and a
null parameter or buffer or a maximum length outside 1 to 2048 is
refused, as in shadPS4.

A resource-cache entry keeps every sampled texture of its descriptor sets alive. The sampled texture cache passes over textures something else holds and, past its ceiling, drops them anyway; textures it makes without caching are never in it. Entries holding either kept them alive with no budget counting them, bounded only by the 1,024-entry and 65,536-element counts, until device memory ran out.
The texture cache now marks such textures released. ResourceCache::Insert refuses descriptor sets holding one and hands the entries that hold one back to the caller, like RemoveImage does for evicted storage images.

FC 27 stops on Windows with Failed to load module / error 126 because this PRX is absent. Export Initialize and Terminate as no-ops and keep RequestDevices throwing until the buffer layout is known.

sceAudioOut2ContextGetQueueLevel left out the grains that
sceAudioOut2ContextAdvance completed and no push had consumed yet. While
pushes filled the 40 ms cushion the level stayed at 0, so a title that
renders as many grains as the level leaves room for and pushes them on
another thread rendered a full queue again after each push. PPSA23226's
Wwise sink does that and stopped once more than 16 completed grains
awaited a push.

The ancillary input's sample number (bits 11:8) was the SampleId
builtin in every pixel shader. Vulkan enables sample shading for a
shader that uses SampleId, so a shader that reads the sample field or
the whole ancillary word ran once per sample on a multisampled draw
even when the guest runs it once per pixel (PS_ITER_SAMPLE clear), and
FragCoord, and with it POS_X_FLOAT and POS_Y_FLOAT, moved to the
sample. The sample number is now SampleId only when the request says
the guest iterates the shader, and otherwise 0, the iterated sample
number of a pixel the hardware does not iterate.
The other inputs that depend on the sample follow where the console
evaluates them:
- PERSP_SAMPLE and LINEAR_SAMPLE are interpolated with
InterpolateAtOffset at sample 0's offset in a shader the guest does
not iterate, and in an iterated one at the offset of the host's
SampleId, read from a table of the guest's locations, because Vulkan
leaves plain barycentrics under sample shading at an
implementation-defined position (lavapipe uses the pixel centre).
- PERSP_CENTER and LINEAR_CENTER are interpolated at offset 0 in an
iterated shader.
- POS_X_FLOAT and POS_Y_FLOAT follow SPI_BARYC_CNTL: the centre is
floor(FragCoord) + 0.5 under sample shading, a sample position in a
shader the guest does not iterate is the centre plus sample 0's
offset, and POS_FLOAT_ULC gives the upper-left corner.
The offsets need InterpolationFunction (sampleRateShading) and the
fragment-shader barycentric path; devices without them keep the host's
default positions. The shader disk cache format goes to 39.
