A playing sampler voice whose waveform still accepts blocks (CONTINUE)
reported only INUSE|PLAYING after it had played every queued block, so
a title that waits for EMPTY before it reuses the voice never did.
PPSA18391 (engine: Clickteam Fusion) reads state_flags & 0x22 != 2 from
sceNgs2VoiceGetState as the end of a sound; each of its sound effects
played once and never again.
The voice now also reports EMPTY (0x20) in that state and keeps
playing, so blocks added later still play. A waveform that was closed
without CONTINUE does not report it.
scePthreadJoin threw when a joinable thread joined itself and
scePthreadJoin and scePthreadDetach threw on a null thread, so
pthread_join and pthread_detach ended the process where FreeBSD libthr
returns EDEADLK and EINVAL.
Registering a flip or vblank event on a handle that sceVideoOutOpen never
created, or that was closed, threw, which ended titles that register
their flip event before they open the port and ignore the result. The
documented error SCE_VIDEO_OUT_ERROR_INVALID_HANDLE is returned instead,
the same check sceVideoOutSetFlipRate and the other output calls use.
The flip test program gains an "unopened" mode.
An indexed draw that binds its index buffer in place from a host import
(#2253) scans the bound range for its highest index on every draw, where
the copied path reuses the value kept with its snapshot. A draw of many
indices pays for the scan each time, and an indirect draw, which binds
the whole declared index buffer, scans the whole buffer per draw.
The recorder now keeps the highest index of an in-place index range of
4096 indices or more with the write generation collected before the
scan, and a draw takes it while the range is unchanged since
(GuestMemory::UnchangedSince and the allocation registry generation, as
for a reused snapshot). A smaller range is scanned at every draw as
before: the scan costs 0.4 ns per index and the write collect and lookup
0.2 to 1.4 us per draw, so the scan is the cheaper of the two below
about 3,000 indices, as #2253 measured on small ranges.
Resident Evil 4 (PPSA07411, #2776) and PRAGMATA (PPSA02530, #3043) stop

Deathloop, Minecraft Legends and Cyberpunk import the base-object
constructor InitParameter2::InitParameter2(), InitParameterRtti2::
setAllocatorRtti and InitParameterRtti::InitParameterRtti(AllocParamRtti*,
void*, unsigned long), which were NotImplemented stubs.
InitParameter2 is the 40-byte object of SharpEmu and KytyPS5: the
allocator, its user data, the file buffer size and the 32-bit special
float format type at 0x18. Both constructors zero it, setAllocatorRtti
writes the allocation parameters and user data where setAllocator writes
the allocator, and setSpecialFloatFormatType stores the type.
InitParameterRtti's constructor writes its three arguments to the first
24 bytes. The NID WVZBP4IyM+E recomputes from the mangled name and is in
the aerolib database. The enum's values are unknown, so no value is
rejected; the inferred layouts are recorded in TechnicalDebt.

scePthreadKeyCreate and pthread_key_create handed out the slot index,
so the first key in a process was 0. FreeBSD libthr returns slot + 1
(_pthread_key_create: "*key = i + 1") and subtracts 1 again in
pthread_key_delete, pthread_getspecific and pthread_setspecific, so 0 is
never a valid key. Code that keeps 0 as "key not created yet" therefore
created a new key on every call and lost the values it stored under the
previous one.
Keys now start at 1; 0 and other out-of-range keys are rejected with
EINVAL by delete and set and read as NULL, as before.

sceKernelClose passed every descriptor to the host close. Guest socket
descriptors start at 0x10000000 and are not host descriptors, so closing
an open socket returned SCE_KERNEL_ERROR_EBADF and left it in the guest

as close, sceKernelRead and sceKernelWrite already do; a closed socket
still returns SCE_KERNEL_ERROR_EBADF.

The guest identity predicate accepted .debug_prx while Domain::ImportModule
did not: a dependency named libGuest.debug_prx normalised to
libGuest_debug_prx, so a qualified import declared in module libGuest was
left unscoped. When another guest module exported the same symbol, the
conversion failed with an ambiguous guest import, while .prx, .sprx and
.suprx resolved to the declaring module.
Module suffixes are now one list in the domain layer, used by the identity
predicate, import module normalisation and the default .prx suffix.
Needed-name stem aliasing keeps its own list.

Exports pause (EDyhWelj7UY), sigwait (mrbHXqK8wkg) and sigwaitinfo
(Uq5BGthgbl4) from libkernel. NIDs computed with tools/nid_names.py and
matched in aerolib; ps5-payload-dev/sdk f5d40f02 sce_stubs/libkernel.c
places all three in libkernel.
They throw like the merged sigtimedwait (#3430), with the same message
pattern: "sigwait: waiting for a pending signal", "sigwaitinfo: waiting
for a pending signal" and "pause: waiting for a delivered signal". In
FreeBSD 11.4 (8c639945) sigwaitinfo is kern_sigtimedwait without a
timeout (sys/kern/kern_sig.c:1212), sigwait is the same wait returning
the error number (kern_sig.c:1150, lib/libthr/thread/thr_sig.c:676-728)
and pause is sigsuspend of the current mask (lib/libc/gen/pause.c:46-56).
AnyPS5 never leaves a guest signal pending (blocked signals are dropped
in Dispatch, raise delivers at once), so there is nothing to take, and
raise, kill and pthread_kill run a handler only on the calling thread,
so nothing can end a pause.
Titles (predicted stops, registry order; not observed runs):
- Ruffle PPSA68091, observed today
"FAIL: unresolved ELF import 1t1-JoZ0sZQ from libSceLibcInternal.prx"
(sinhf, #3519), predicted next
"FAIL: unresolved ELF import EDyhWelj7UY from libkernel.prx"
(pause, call site 0x8F7266).
- RetroArch PPSA99169: pause (0x30DB1, an address table entry).
- PS5MC PPSA99420: pause (0x3BD80F6, 0x3C9E220), sigwait (0x3C9E4C7),
sigwaitinfo (0x3C9E588).
- XPSemu PPSA97358: sigwait (0xE02AEC, 0x1101294, 0x1101368), QEMU's
dummy vCPU thread and sigwait_compat thread.
guest_sigtimedwait now also checks the three throws, with an empty set,
a null info, a SIGINT raised while blocked, and that neither the output

NativeError listed 17 Winsock and 17 POSIX errors and turned every other
one into EIO. A second connect while the first is pending (WSAEALREADY,
EALREADY) and an option the host rejects (WSAENOPROTOOPT, ENOPROTOOPT)
reached the guest as EIO; on Linux a nonblocking connect (EINPROGRESS),
a send with no destination (EDESTADDRREQ), ENOTSOCK, EAFNOSUPPORT,
EOPNOTSUPP and others did too.
The translation moves to SocketError.hpp and covers the socket errors of
both hosts by name, with the FreeBSD 11 numbers. WSAESHUTDOWN stays EPIPE
as before. socketpair's own table is gone, as NativeError covers it.

FindF16x2Math read spirv[offset + 1] for every instruction once the f16 vector type was known, so a final one-word OpFunctionEnd read past the module. Check the opcode and its minimum word count before reading operands.
v_pk_add_f16 and v_pk_mul_f16 computed each half in f32 and rounded it
back to f16, then fixed the NaN, FP16_OVFL and clamp results on the
bits. On a device with native f16 that rounds to nearest even and keeps
f16 denormals (the Float16, RoundingModeRTE and DenormPreserve
capabilities that #1252 already checks), the arithmetic is now one
f16vec2 OpFAdd or OpFMul decorated NoContraction, and the same NaN,
FP16_OVFL and clamp rules run on its result bits.
The results don't change. f32 has at least 2 * 11 + 2 significand bits,
so rounding an f16 sum or product to f32 and then to f16 gives the
correctly rounded f16 result. Vulkan requires f16 OpFAdd and OpFMul to
be correctly rounded, the module keeps f16 denormals, and any NaN they
produce is replaced by the NaN the existing rules select.
v_pk_fma_f16 and v_pk_fmac_f16 keep the f32 path: Vulkan gives GLSL Fma
only the precision of OpFMul followed by OpFAdd, so a native f16 Fma
may round twice.
New test agc_driver_packed_float16_native compiles one shader with
packed add, mul, fma and fmac (op_sel, op_sel_hi, neg_lo, neg_hi and
clamp variants) with and without Float16, checks that only add and mul
use f16vec2 math, and compares every result bit for bit on random and
special inputs (zeros, denormals, infinities, NaNs, values near the f16
maximum) in nine float modes.
The default terminate handler formatted its whole report into a 1024-byte
buffer, so a long what() was cut off without a trailing newline. Driver
refusals that carry a serialized RecompileRequest lost most of it, and the
next log line ran into the truncated text.
The report header still goes through the bounded RawLog, and what() is
now written in full by a raw write to the stderr handle, followed by a
newline. Both keep avoiding the CRT stream lock, as before.
exception_runtime gains a forked child that throws an uncaught
runtime_error with a message over 3000 characters and checks that the
full what() reaches stderr before SIGABRT.
The test only ran in the full recorder binary, which no ctest entry starts. It now has its own mode and entry (agc_multisample_guest_access); with the guard back at the single-sample size its new padding row fails.
The guest-access guard covers CB bytes times samples (the single-sample layout size alone missed the later sample planes' tile padding), with a test row in that padding. Remove two TechnicalDebt lines duplicated by the rebase, document the guard bound and the unevicted targets, and add the multisampled targets to ARCHITECTURE.md.
A multisampled target's samples are only on the host, so its guest memory
never holds them: a CPU read through GuestMemory::Read/ReadCommitted, a
DMA_DATA copy from it and a texture or storage image lookup at its address
throw instead of returning bytes that were never written there. Asked by
oneandonlydean; the test reads a resolved-only target's memory each way.

The duplicate ColorTarget::cmaskAddress, decode and size helper are gone: multisampled targets
use main's cmaskAddress/cmaskBytes (whole metablocks). Single-sample targets keep main's rule
(CMASK under FAST_CLEAR); a multisampled one takes it under FAST_CLEAR or COMPRESSION. A zero
fill of the whole CMASK clears at the next use, 0xFFFFFFFF marks it expanded, any other or
partial fill refuses the next use; eliminate/DCC passes over a multisampled target and a CB
resolve into a fast-clear destination are refused. The draw key adds CMASK_BASE_EXT (0x398),

Draws with PA_SC_AA_CONFIG multisampling (2, 4 or 8 samples, every target with as many
fragments, the standard sample locations, MSAA_ENABLE) render into host-only multisampled
color images and multisampled depth surfaces; the pipeline rasterizes with that sample
count. A CB_COLOR_CONTROL resolve over a multisampled CB0 runs as a render pass whose
resolve attachment is CB1's resident image. A zero fill over a target's CMASK fast-clears
it to the CB_COLOR_CLEAR_WORD values of its next use. EQAA, coverage conversion,
nonstandard sample locations, sampling a multisampled surface and multisampled mips stay
refused.

Guest paths were normalized lexically before they reached the host, so
"missing/../file" and "file/../x" dropped the component before "..":
stat and open succeeded on the file, unlink deleted it and rmdir removed
a directory, where FreeBSD's lookup() resolves ".." with VOP_LOOKUP in
the directory reached so far and fails with ENOENT for a missing
component and ENOTDIR for a file. POSIX path resolution (XBD 4.13) says
the same.
".." is still collapsed lexically when the path before it is an existing
directory, so case-insensitive matching and aliases behave as before.
When it is not, the rest of the path is passed to the host unchanged and
the host resolves it. Linux then reports ENOENT or ENOTDIR as FreeBSD
does; Windows collapses ".." itself, so its results are unchanged.

FreeBSD returns the difference of the lowercased bytes where the strings
differ, including where one of them ends. The guest wrappers returned the raw
difference of the terminator and the unfolded byte, so strcasecmp("ab", "A")
gave 66 instead of 98.
FreeBSD's soreceive leaves the sender unset for a stream socket, so recvfrom
returns an address length of 0 (kern_recvit). The guest call formatted the empty
host address as a 28-byte AF_INET6 sockaddr and reported length 28. Report
length 0 when the host returns no AF_INET or AF_INET6 sender, as recvmsg does.
FreeBSD's kern_clock_nanosleep writes the remaining time only when the sleep is cut short. A completed sleep zeroed rmtp, so nanosleep(&ts, &ts) in a polling loop slept zero time from the second call on.

close() of a descriptor that is not open calls _close, which raises the
UCRT invalid-parameter handler before returning EBADF. In a relinked title
that handler is libc's crash reporter, so an ordinary close of a closed
descriptor printed a FATAL report and every thread's stack. The call now
runs with the thread-local no-op handler, as dup and dup2 already do.

The abort() and UCRT invalid-parameter reports capture the stack with
RtlCaptureStackBackTrace, which stops at the first frame without unwind
data (guest code, or our libraries built without asynchronous unwind
tables), so they often end two or three frames in, before any caller.
The fault report already scans the stack for code addresses; that scan
is now a helper the backtrace reports use as well.

Two more agc_driver_relative_indexing rows read a register of the window
the program never wrote, directly and through v_movrels_b32, and expect 0,
which the zeroed window array gives like an unwritten SSA register did;
the TechnicalDebt entry says the console's value is undefined.

A pixel wave starts with only its covered pixels in EXEC, so a shader that
takes an implicit LOD has to run s_wqm first or the helper lanes of a partly
covered quad hold no coordinate. The test's pixel shader did not, which goes
unnoticed while its one triangle covers every quad whole. llvmpipe clips that
triangle at twice the viewport into three, and in the quads on the two inner
edges the helpers' zero coordinate gave the last mip instead of the expected
one.
The shader now starts with s_wqm_b64 exec, exec, as a compiled pixel shader
that samples with an implicit LOD does.
M0 is unsigned, so an index at or past the window reads v0 and drops its
write, v_swaprel_b32 writes neither side when either is out of range, and
the window array starts zeroed like unwritten SSA registers; the window
load counts as a lane source so a wave64 program's second half keeps its
own registers. agc_driver_relative_indexing runs in wave32 and wave64 and
pins the rows measured on gfx1035 in the review of #3856, and the
TechnicalDebt entry states the measured behaviour, the window's end at the
last named register and the sizes.

The f16 unary ops, v_frexp_mant_f16, v_frexp_exp_i16_f16, the norm
conversions and v_cvt_f32_f16 read denormal halves as they are and
rounded denormal results as they are, whatever the denormal field of
FLOAT_MODE says. On RDNA2 a clear bit 0 flushes a denormal half input
to its signed zero and a clear bit 1 flushes a denormal half result.
One shared rule now drives all of them, and v_ldexp_f16 uses it for its
input too.

PPSA28416 calls it on its existing save at boot (after sceSaveDataDirNameSearch finds it) and aborted on the missing implementation. The call takes one parameter block: user id at +0, the directory name pointer at +8. Host saves have no size limit, so the conversion completes at once: an existing save returns OK, a missing one NOT_FOUND, an invalid name PARAMETER. The title polls sceSaveDataGetEventResult once afterwards and continues on 'no event'.
Goat Simulator 3 (PPSA04159) imports sce::Json::Object::find(String const&)
const (ehN1Biw3tw8), Object::iterator::operator->() const (EnesV4gXDtE) and
String::compare(char const*) const (Yfw63FVJgtU); without them the Windows
entry stub stops before the game starts with "unresolved ELF import
ehN1Biw3tw8".
find returns an iterator to the first pair whose key equals the argument,
or end(), using the same key match as Object::operator[]. operator->
returns the pair like operator*. compare orders the string against a C
string as std::string::compare does; a null argument throws.

sceVideoOutSubmitChangeBufferAttribute2 threw when a buffer of the group
had a flip pending, and Marvel's Wolverine makes that call with flips in
the queue. A flip now takes its buffer group when it is reserved, in
submission order, so flips submitted before the change keep the
attributes their buffers were rendered with and later flips use the
new ones.

PPSA19546 (Cookie Clicker) and PPSA34959 (The King is Watching) list
libSceXml.prx among their needed libraries but import nothing from it.
AnyPS5 builds no such library, so on Linux the dynamic loader stops both
before they run:
./eboot.elf: error while loading shared libraries: libSceXml.prx:
cannot open shared object file: No such file or directory
On Windows the start-up stub has skipped a missing library that nothing
imports from since #3129; the Linux loader resolves DT_NEEDED itself
and cannot skip one. libSceXml now exists with no exports, like
libSceAgcVsh and libSceAudio, so it loads on both. A title that imports
from it still stops at the missing import.
Both titles now load and stop at their next missing import:
setSpecialFloatFormatType (PPSA19546, #3575) and sceHttpsFreeCaList
(PPSA34959, #3497).
Extend the decode test to mul:4, div:2, -|v2|, -|v2| div:2, a p2
coordinate with neg and a non-zero attribute channel, a clamped p2, and
the mov form with clamp and mul:2. All 18 accepted words are the
assembler output (llvm-mc -mcpu=gfx1010).
The search returned saves in host directory order and ignored the condition's key and order. A title that asks for the newest save first (modification time, descending) got whichever directory the host listed first: the alphabetically first on NTFS, an arbitrary one on Linux. Sort by directory name, user parameter or modification time, reverse for a descending order, and reject unknown keys and orders with the parameter error, as shadPS4 does.
PPSA06888 stops on main at start-up because its bundled
Media/Plugins/SceRudp.prx imports sceRudpEnableInternalIOThread2,
sceRudpGetOption and sceRudpGetRemoteInfo, which no library exports.
The signatures are unknown, so they are declared without parameters and
throw. The title does not call them during start-up.

One queue for APR and AMM buffers kept an AMM buffer behind an APR buffer
waiting on an address that the AMM buffer writes, so neither ran.
Marvel's Wolverine does this: an APR buffer waits on a counter that the
WriteAddress commands of later AMM buffers advance, and its loading
stopped. APR and AMM buffers now keep their order within their own queue.

sceKernelGetModuleInfoFromAddr has a Windows path since 77ef75c1d, so
_sceLibcInternalForceTlsDestructor finds each dso's module there too.
The test takes the other module's address with GetProcAddress where
Linux uses dlsym(RTLD_NEXT), and the TechnicalDebt entry no longer says
the call throws on Windows.

A rect-list draw whose count is not a multiple of 3 threw "incomplete rect-list
primitive". Rect lists are drawn as patch lists of 3 control points, and Vulkan
generates floor(vertexCount/3) patches, so the draw now records as is and the
trailing 1 or 2 vertices are left out. Palworld (PPSA23126) draws 4 vertices x 9
instances as a rect list when character creation opens (#3832).

scePadOpen returned the standard pad's handle for a special port
(type 2) as well, and scePadGetHandle found it there. Both ports then
read the one input queue, so a press queued between two frames could be
drained by the special port's read and never reach the standard port.
PPSA16827 (Harmony's Odyssey) opens both ports for the initial user and
reads both every frame, also polling controller information and device
class data for the special one.
Special ports now return DEVICE_NOT_CONNECTED (0x80920007) from
scePadOpen, as scePadOpenExt already does because the host has no
special controller, and scePadGetHandle has no handle for them.
TechnicalDebt's scePadOpenExt entry now covers both calls.
guest_pad opens a special port before and after the standard one and
expects DEVICE_NOT_CONNECTED, and DEVICE_NO_HANDLE from scePadGetHandle
for the special port while the standard handle stays valid. It fails on
main.
PPSA16827 over 130 s of its title screen: 6812 scePadRead, 3408
scePadGetControllerInformation and 3406 scePadDeviceClassParseData calls
before, two reads of the same queue per frame; 2702 reads, one
information call and no parse calls after.
Elden Ring Nightreign (PPSA25380) imports the function, which no library
exported, so the title failed to load. The option is ORed into the buffer
attribute and a null attribute throws. Options other than 0 and 8 still
throw when the buffers are registered.
`v_movrels_b32`, `v_movreld_b32`, `v_movrelsd_b32`, `v_movrelsd_2_b32`
and `v_swaprel_b32` lowered to a compare-and-select chain over every
register from the base to the program's last allocated register, so a
program addressing 154 registers 104 times turned 3176 ISA words into
649,515 SPIR-V words that Intel's compiler did not finish. The registers
from the lowest relative base up now live in a function-scope array per
invocation (`LoadVectorWindow`/`StoreVectorWindow`), so an indexed access
is one load or store; plain accesses to those registers go through the
same array, DPP-modified relative writes keep their `DppUpdateU32` merge,
an index past the window reads 0 and drops its write, and programs
without relative addressing are unchanged. The same program recompiles
to 392,333 words with 4,992 selects instead of 32,383.

mingw's fprintf writes an unbuffered stream a character at a time and
holds the stream's lock for the whole line. The APS5_LOG_* lines that
carry a RecompileRequest ("Shader ... could not be prepared after
registration", 15-20 KB each) took one WriteFile per character, and every
other thread writing to stderr waited behind them, guest calls that log
included. Demon's Souls (PPSA01342 v1.005, Windows) stops on a black
screen after two frames on main: a BPE job worker waits for the stderr
lock in sceSaveDataDirNameSearch's trace while the shader preparation
pool prints its dumps, so GameCoreLoop never finishes a frame.
The log macros now format the line into memory and write it with one
fwrite, as Driver::reportSkip does since 8cf2f6580. The UCRT writes an
unbuffered stream's fwrite as one even-length block and the last byte,
so a line takes at most two writes on Windows and one on Linux.

sceKernelGetOperationMode returned 0 for both values, which were
unknown. A payload on a PS5 (firmware 13.60) reads mode 2 and submode 0;
nothing past the two ints is written and the result register holds no
status, so the function now returns nothing. PPSA12544 logs both values
and ignores the result.

Hollow Knight Silksong (PPSA12544) imports libSceAgc NID vieBRwlh1Lw
(#699). Its name is unknown: it is not in aerolib, and the
sceAgcUpdateInterpolantMapping label other projects give it hashes to
SbuY2jN+axQ.
OpenAGC (src/game_compat.c at 3c7e807, sceAgcUnknownVieBRwlh1Lw) reads
it from FW 11.60 as the dbOlWdppb4o transform with the same (regs, gs,
ps) arguments, without the identity tail: it writes one register per
pixel shader input, none for a pixel shader without inputs, and rejects
a null pixel shader. It now shares the dbOlWdppb4o path and throws for
the rejected arguments.
For is_f16 1 and 3 inputs whose default_value and default_value_hi
differ, OpenAGC takes DEFAULT_VAL from default_value_hi, while KytyPS5,
sharpemu and dbOlWdppb4o here take it from default_value; these inputs
throw. On every other input the dbOlWdppb4o values equal OpenAGC's.
agc_interpolant_mapping runs the dbOlWdppb4o vectors and OpenAGC's
enhanced-mapping vectors through it.

agc_driver_f32_denormal_flush fails on RADV RENOIR (Mesa 26.2.4):
lane 20 no float mode v_fma_f32 v14, v4, v5, v6 is 0x00800000, expected 0x00ffffff
The driver lowers Fma to a multiply and an add: the compiled shader has
v_mad_f32 and no v_fma_f32. The product 0x1fffffff * 0x1fffffff is below
2^-126 and is flushed before 0x00800000 is added. Lane 20 is the only
row with a tiny product and a non-zero addend. v_fma_f32 and v_fmac_f32
fail on it in all three float modes; every other check passes.
When both return that sum, the two values are not checked. FmaRounding
already leaves out its fused forms on a device that splits fma.
sceKernelGetModuleInfoFromAddr found the size of the image's .eh_frame
on every call by walking all of its CIE and FDE records, checking each
against every PT_LOAD header. The guest libc's unwinder calls it for
each frame it unwinds, so a title that unwinds often walked its whole
.eh_frame hundreds of times per second.
The tables read from a .eh_frame_hdr are now kept per header address
and reused while the image stays loaded. The cache is dropped whenever
dl_iterate_phdr reports that an object was unloaded (dlpi_subs), so an
address reused by another image is read again.
guest_module_info queries a module twice and expects the same tables,
then unloads it, loads it again and expects tables of the same size at
the same offset in the new image.
PPSA16827 (Harmony's Odyssey), title screen, over 500 calls per second
counted under gdb, which slows the title: the process used 9269 CPU
samples per 10 s, 53.7% of them in this walk, and 3306 with this change,
3.2% in the lookup. The title still runs at 27 FPS; its frame rate is
limited elsewhere.
Rows that run the same kernel at the same wave size compile the same
pipeline, so each part now takes whole groups of them, and the test is
split into fourteen parts. Each shader is compiled once per CI run
instead of in up to three parts at once.

Surround Sound Studio (PPSA99051), catalog build on main a11c8f7f with
the flat-interpolation fix, stops 16 s in, before its first frame
(orishamir, #3581 comment 6109839314):
sceAudioOutSysGetHdmiMonitorInfo not implemented
The call takes (type, out, size); out must be non-null, size exactly
0x180 and type 1 (HDMI) or 0x10 (sainsaji/PS5-Audio-Passthrough-Research
c3be9c2a, docs/FINDINGS.md section 3 and AGENTS.md:25, firmware 12.70).
Titles read the monitor name at +0x0B, the descriptor count at +0x94 and
8-byte descriptors from +0x98 (same, FINDINGS.md hardware log item 1 and
sample-app/src/platform/ps5/bitstream_out.cpp:92-128).
Audio reaches the host through SDL as PCM and there is no EDID, so type 1
with a 0x180-byte buffer reports a sink without a name or descriptors:
the buffer is zeroed and 0 is returned. Surround Sound Studio's
Passthrough page then lists no formats; EVO Player's code treats an empty
list like a negative return. A null buffer returns 0x80260004, as the
other AudioOut calls do. Type 0x10, other types and other sizes throw:
their results and error codes are not known.

v_cvt_i16_f16 with mul:2, mul:4, div:2 or clamp in the VOP3 encoding
stops the recompiler with "VOP3 source modifiers are not implemented".
On gfx1036 (Radeon 610M) the result is identical with and without
mul:2, mul:4, div:2 and clamp combined with mul:2, for all 66 measured
inputs; clamp on its own is not a measured case.
The decoder now accepts omod and clamp on v_cvt_i16_f16 and drops them,
as measured. Clamp without an output multiplier is accepted by the same
rule: clamp with mul:2 gives the same hardware result as mul:2 alone.
Matches 528 of 528 rows in two float modes, 0 differing.
v_cvt_u16_f16 is not measured and stays refused.

Dying Light 2 (PPSA02262) imports sceKernelAioSetParam (9WK-vhNXimw) from

with "12 other imports are still unresolved on `main`. In the eboot,
`-q-vbO859Tw`, `GTfJ64qFCPw`, `vwtVpHQKelI` (no known names),
`sceKernelAioSetParam` and `sceNpWebApi2GetMemoryPoolStats`." The import
is observed; its position in the loader queue after the nameless NIDs is

The function fills one SceKernelAioSchedulingParam (five 4-byte fields,

sceKernelAvailableFlexibleMemorySize and the flexible maps counted only
explicit flexible mappings, so the full 448 MiB was reported while the
title's executable and modules were loaded. A title that derives its code
and data size from the budget minus the available size got an unsigned
underflow.
The segments of the main executable and of every .guest.prx module that
the title's ELF gives permissions now count, rounded to 16 KiB pages, as
shadPS4 maps every non-system module segment as flexible memory. The
relinker's own blocks and the host system libraries do not count. The
charge ends when a module is unloaded.
