AI-assisted: yes. Record that gethostname exposes AnyPS5 rather than the native machine name. Console hostname configuration, sysctl integration and name resolution remain unverified and unimplemented. This one-line note is placed beside an unchanged libc compatibility entry so the branch merges cleanly into tested main 5edae3536.
PPSA11386 calls sceSharePlayInitialize(NULL, 0x1800) at start-up and stops
on any non-zero result, so the console accepts a null heap. The library
keeps no state and does not use the heap; a zero size still throws, as its
error is unknown. libSceSharePlay gets its own CMakeLists for the test.

An NGG passthrough program on the vertex path whose s_barrier only orders wave 0's GS_ALLOC_REQ produced a workgroup OpControlBarrier, which the Vertex execution model does not allow; SPIR-V validation rejected the module at the program's first draw. In a Vertex-stage program the barrier now emits nothing when the program has no LDS or GDS access and no memory write or atomic, so no wave can observe another. With any of those it throws.
A comparison sample with a 2D-array address on a plain 2D color T# takes the emulated comparison, whose runtime modes were only the 2D-array and cube ones. No mode matched, and materialization threw that the image descriptor was incompatible with the static runtime image interface. The emulated comparison now also gets a 2D mode, as the native modes of a 2D-array access already have; the slice is ignored.
The ternary forms share minMaxF16 with v_min_f16 and v_max_f16 and follow
the same rule on gfx1036: a subnormal half input becomes a signed zero when
bit 0 of the f16 denormal field is clear, at IEEE=0 and IEEE=1.

The mutex attribute now keeps its protocol and priority ceiling the way
FreeBSD's libthr does: the ceiling can be set and read only under
PTHREAD_PRIO_PROTECT (EINVAL otherwise), and setting a protocol resets it
to the highest SCHED_RR priority. Mutexes still do not apply priority
protection; that is listed as a silent stub.

(cherry picked from commit d10c024f8f)
A map without MAP_FIXED whose hint lies wholly inside a range still
reserved by sceKernelReserveVirtualRange is placed at the hint, as a fixed
map into the reservation would be. Hints outside reservations and ranges
that are partly mapped keep their hint behaviour. The reservation is
checked under the registry mutation, so it cannot be released and its
address reused between the check and the map (MarcZX100, #2687).
Fixes#2687

Registration prepares the variants a shader's registered state
predicts; a draw or dispatch whose state needs another one threw
"prepared shader artifact is missing for the requested static ABI".
Titles that link their own libSceAgc build that state themselves and
never call the driver's static ABI resolution, so their draws differ
from the registered prediction. The missing artifact is now prepared at use, logged, and kept
with the snapshot like the deferred and null pixel cases. SourceHandleFor
now checks that the request refers to the registered code, as
InvocationFor already did.
Uncharted: Legacy of Thieves Collection (PPSA05684) still misses on
main 197ffac9 (after the fixed push slots of #2661) for its own pixel
shaders: "prepared shader artifact is missing for the requested static
ABI: address=85899411712 stage=5 wave=64 pushOffset=128
pushCapacity=128".
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".
sceAvPlayerAddSource queues an auto start for a player created with auto
start or without an event callback. When the title enabled its streams
and called sceAvPlayerStart before the controller thread ran it, the auto
start called Start again on the playing player, which stopped it, released
every video buffer, including the frame the title held, and started the
film over. guest_avplayer occasionally caught this as "video frame is not
a texture allocation"; right after the test's own start, 8 texture
buffers were released in 15 of 15 runs.
The auto start now starts the player only while it is still ready, and
checks that under the player lock together with the start.
TestAutoStartKeepsStartedPlayback starts a callback-less player itself and
checks that no texture buffer is released afterwards and that the frame
it holds stays allocated. It fails on every run without the fix.
RDNA2 min/max flush half inputs to signed zero when input
preservation is disabled, while output flushing alone keeps them.
Apply this to the measured binary forms and pin the hardware rows.

Validate timeout arguments and track live requests so unknown or deleted
ids return REQUEST_NOT_FOUND. This supplies the remaining absent load
import alongside the dialog Close export; timeouts follow the existing
offline network model and are not stored.

sceAjmBatchJobDecodeSplit queues a split run job with the stream
sideband, as sceAjmBatchJobDecode does for a single buffer pair.
sceAjmBatchJobSetResampleParametersEx with a zero ratio change per
sample sets the ratio as sceAjmBatchJobSetResampleParameters does; a
non-zero change throws, since its ramp is unknown.

Measure the mixed f16/f32 boundary on gfx1036 and pin both factor
slots, half selection, signs and zero f16 addends in the existing test.
Record this measured scope while keeping legacy mad/mac unchanged.

With f32 denormals flushed, RDNA2 flushes a product only when its value
rounded to 24 bits in the current round mode is below 2^-126. The
tiny-product check tested the exact product, so products that round up
to 2^-126 became zero in v_mul_f32, v_mul_legacy_f32, v_mullit_f32 and
zero-addend f32 FMAs. The separately rounded v_mad_legacy_f32 and
v_mac_legacy_f32 keep the exact check, as they are not measured there.

VLC (PPSA85300) imports execvp (0NJDcQ2B8vE) from libkernel and fails
to load because no library exports it. Replacing the process image is
not supported, so it throws if called, like sceSystemServiceLoadExec
does for executable replacement. VLC itself cannot reach the call: its
fork and vfork fail with ENOSYS, so the child that would call execvp is
never created.
PPSA11386 imports it; on main it is one of the title's three missing
imports, with sceSslGetCaList and sceSslFreeCaList, and the title does not
call it during its start-up. The signature is unknown, so it is declared
without parameters and throws.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
PPSA11386 imports sceSslGetCaList and sceSslFreeCaList and PPSA15508
imports sceSslUnloadCert; on main all three are missing and the loaders of
both titles stop on them. No root certificate bundle is shipped and no
loaded certificate is kept, so an SSL context holds no certificates:
sceSslGetCaList clears the list and returns NOT_FOUND, as sceSslGetCaCerts
does; sceSslFreeCaList accepts only that cleared list; sceSslUnloadCert has
nothing to drop and is assumed to return 0. A null list returns the
invalid-argument code that sceSslGetCaCerts and KytyPS5 return. An unknown
context and a list sceSslGetCaList did not return throw, as their codes are
not confirmed. Signatures and the SceSslCaList layout follow SharpProspero
and shadPS4.
guest_ssl_tests now links libc, as guest_http2_tests does, so an exception
thrown from libSceSsl unwinds with the same unwinder that resumes it.

An upload of a storage image up to 1 MiB reads the surface's guest bytes
into a baseline (#1599), which a later write-back compares against for
blocks the CPU stamped. When a unit shadow, another image's pending
results or a recorded GPU store covers the surface, that read goes
through the flush hook: the shadow is published and the worker waits for
the GPU, although the upload itself runs on the GPU from the import.
The baseline is now taken only when nothing of that kind overlaps the
surface. Otherwise the image has none, and its write-back keeps the CPU's
bytes for stamped blocks, the rule before #1599. TechnicalDebt's entry
names the condition.
agc_storage_baseline_settled creates a storage image over a watched host
import with a recorded store pending over part of it and checks that the
upload did not submit the open batch; without the change the baseline
read syncs on that store. agc_unchanged_cpu_stamps (#1599) still passes.
PPSA14632 (LEGO Horizon Adventures) refreshes such images about 870
times per 10 s from queue 0 dispatches: the hook's recorded-store syncs
go from about 3400 waiting 4.0 s to about 630 waiting 0.3 s per 10 s,
and a direct dispatch's device call from 356 to 107 us.

Jelly5 (PPSA99505) imports sceAudioOutExGetMonitorInfo (PhnNN0UEV6Y),
sceAudioOutExConfigureOutput (VcE+gXSwFXI), sceAudioOutExOpen
(6X6dp+07h4U) and sceAudioOutExClose (0TfjSulCV2A) from libSceAudioOut
and fails to load because no library exports them. It calls them only
for its optional HDMI bitstream output, and their signatures are
unconfirmed, so they are exported without an implementation and throw
if they are called, like sceSaveDataCancel.
Read rtkit's MaxRealtimePriority and RTTimeUSecMax before touching the
limit, keep a hard limit that already satisfies rtkit, lower the soft
limit to at most half of the hard one, and log when the hard limit is
lowered. rtkit checks the hard limit, so it cannot be left alone when it
is above RTTimeUSecMax; the side effect is listed in TechnicalDebt.md.
Log the policy rtkit applied, SCHED_RR by default.
