sceVoiceSetMuteFlag was NotImplemented with an unknown signature and
sceVoiceGetMuteFlag was not exported. Signatures follow shadPS4's
voice.h: a port id and a bool, and for sceVoiceGetMuteFlag a port id
and a bool pointer. The flag is stored per port like the volume; an
unknown port throws and a null output pointer is an invalid argument.
Uncharted: Legacy of Thieves Collection (PPSA05684) imports
sceVoiceGetMuteFlag (Pc4z1QjForU), so on main it stops at startup with
"undefined symbol: Pc4z1QjForU".
scePthreadCancel and pthread_cancel threw, scePthreadTestcancel did
nothing and the cleanup handler exports did not exist.
A cancel request is now recorded on the thread and acted on at
scePthreadTestcancel, the condition variable waits, scePthreadSem and
sem waits, scePthreadJoin and the sleeps, and under their POSIX names.
A thread blocked in one of the waits is woken; a condition wait takes
its mutex back before the thread exits. The thread exits with
PTHREAD_CANCELED through scePthreadExit, which now runs the handlers
of __pthread_cleanup_push_imp and __pthread_cleanup_pop_imp.
scePthreadSetcancelstate and scePthreadSetcanceltype reject unknown
values, and pthread_setcanceltype is added.
Constants, the handler node layout and the order of events follow
FreeBSD libthr. A sleep is not interrupted, file and socket calls are
not cancellation points and the asynchronous type acts like the
deferred one except at the two set calls (TechnicalDebt). New test:
guest_pthread_cancel.
Astro's Playroom (PPSA01325) calls sceRudpActivate during start-up, where the throwing stub stopped it. The host has no reliable-UDP stack to activate, so the export returns success and does nothing, matching the OK-returning stubs shadPS4 keeps for the whole library. The guest_offline_imports test now checks the success path with and without sceRudpInit, and still checks that the sceRudpGetStatus sibling throws and writes nothing.
ProsperoStore (PPSA99000) imports kill from libkernel and stops at it on
current main. Its crash reporter resets a crash signal to SIG_DFL and
sends it again with kill(getpid(), signal).
kill follows FreeBSD's kern_kill and killpg1 for the only guest process:
EINVAL for signals outside 0 to 128, signal 0 only checks the target,
and the caller's own pid, 0 and minus its pid deliver through raise.
Any other pid, and -1, which skips the caller, report ESRCH.
VOP2 0x06 measured the same as VOP3 0x140 on gfx1010 (RX 5700 XT) in
wave32 and wave64, IEEE 0 and 1 and f32 denormal modes 0 to 3: the
product is rounded before the add, f32 denormal sources, product and
result are flushed in every mode, and a zero factor gives a +0 product.
It now shares the v_mad_legacy_f32 translation with the accumulator as
the addend, and f32DenormalFlushFor returns 3 for it as well. A new
execution test pins the measured results of its VOP2 and VOP3 forms.

CB_BLENDn_CONTROL factors 15-18 (BLEND_SRC1_COLOR, BLEND_INV_SRC1_COLOR,
BLEND_SRC1_ALPHA, BLEND_INV_SRC1_ALPHA) threw "unsupported blend
factor". They blend MRT0 with the pixel shader's MRT1 export as the
second source, as RADV and radeonsi program it.
DecodeState maps them to the VK_BLEND_FACTOR_SRC1_* factors and accepts
them only with pixel exports to slots 0 and 1, color writes to slot 0
alone, an MRT1 export with MRT0's export format and shader mask, an
ADD, SUBTRACT or REVERSE_SUBTRACT operation and an identity component
order. The blend is draw state, so the specialized module of the
registered pixel shader moves its MRT1 output to location 0 index 1,
which ValidateShaders requires; pipelines need dualSrcBlend, now enabled
when present. The request field dualSourceBlend is in the module key,
the result memo, the draw key and the serialized request (version 15).
sceFontGetCharGlyphMetrics and sceFontGetRenderCharGlyphMetrics set the
vertical bearing and advance to zero although the glyph is loaded with
FT_LOAD_VERTICAL_LAYOUT. The library's own text writing steps the pen by
that vertical advance, so every character of vertical text was placed on
the previous one.
The vertical metrics now follow the FreeType driver's metrics of a
rendered glyph: FreeType's vertical advance, and for a face without
vertical metrics a bearing of half the horizontal advance left of the
horizontal bearing and of half the advance left over by the glyph height.
guest_system_font checks every metric of a square glyph at 100 pixels.

Palworld (PPSA23126) imports sceSaveDataCancel (e6y3WMBYbiM) from
libSceSaveData and fails to load because no library exports it. Its
signature is unknown, so it is exported without an implementation and
throws if it is called, like sceSaveDataConvert.
Guest samplers with DISABLE_CUBE_WRAP (S# word 0 bit 28) are created with
VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT when the device enables
VK_EXT_non_seamless_cube_map; RADV maps the flag to the same bit. The bit
only changes cube filtering, so without the extension the sampler is still
created and only a cube texture sampled through it throws.
waitpid now sits between exit and _exit, and its TechnicalDebt entry follows the packed horizontal gathers entry, so the open system and getuid pull requests and the thread cancellation test pull request no longer touch the same lines.
Unknown options are now checked for every pid, with 0x80 and 0x80000040 added, and so are valid combinations such as WNOHANG | WUNTRACED. Each call is repeated with a null status. The TechnicalDebt entry cites kern_wait, which adds WEXITED and WTRAPPED, and lists pdfork.
waitpid returns -1 with ECHILD, or EINVAL for an option FreeBSD does not know, and leaves the status unwritten: AnyPS5 runs the title as one process and exports nothing that creates a child. VLC PPSA85300 stops on main at this import.
