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.

Eager binding fails when a caller imports sceG2PDialogClose.
Add the missing throwing stub alongside the existing G2P exports
and record the assumed Close signature in TechnicalDebt.

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.

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.
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.
