Draws 32_ABGR exports into a tiled and a linear format 17 target and compares every texel with
the layout X in bits 0-4, Y in 5-9, Z in 10-14, W in bit 15, including the X/Z-swapped pairs, rounding
edges and texels outside the scissor. Reverting the X/Z exchange fails it.

Direct memory can already be mapped more than once, so there is no
aliasing to enable and the call returns 0. ProsperoEden (PPSA99008)
imports it and calls it before mapping the same direct memory again.

SaveDataDirNameSearchResult.infos points at an array the title reads one
entry per returned directory name, but the search never wrote it, and
SaveDataSearchInfo was declared as 128 opaque bytes. A title that asks for
the infos read whatever its buffer held.
SaveDataSearchInfo is now the 48-byte record shadPS4 declares as
OrbisSaveDataSearchInfo (blocks, free blocks, 32 reserved bytes), and the
search fills one per returned name. Every native save reports
SAVE_DATA_BLOCKS_MAX blocks, as sceSaveDataGetMountInfo and the block sort
keys already assume, so both counts are SAVE_DATA_BLOCKS_MAX and the
reserved bytes are zero.
guest_savedata_search_tests checks the two records, their zero reserved
bytes and that the search writes nothing past them.

std::random_device in libstdc++ reads RDSEED on x86 Linux. On an AMD
EPYC 9V45 (Zen 5) CI runner its 32-bit results repeat about 130 times
in 65536 draws, so guest_posix_random fails. libc now exports
HostEntropy_nid_no_patch, which uses getentropy (rand_s on Windows) and
throws when the OS cannot provide entropy. arc4random, arc4random_buf,
sceRandomGetRandomNumber, /dev/random and /dev/urandom reads,
std::_Random_device and sceKernelUuidCreate use it, and the arc4random
and random device TechnicalDebt entries say so.

On a PS5 (firmware 13.60) scePthreadJoin on the calling thread returns
EDEADLK and scePthreadCreate with a zeroed attribute creates a thread
with the default attributes. Here both threw.

On a PS5 (firmware 13.60) the SCE mutex attribute calls return EINVAL
for a null or uninitialized attribute, scePthreadMutexattrSetprotocol
accepts 0 to 2, scePthreadMutexInit takes an uninitialized attribute as
the default one, and destroying a destroyed mutex returns EINVAL. Here
these threw, including for the priority protection protocol.

On a PS5 (firmware 13.60) the scePthreadAttr setters and getters return
EINVAL for a null or uninitialized attribute and for a null output,
ENOTSUP for a policy other than SCHED_FIFO and SCHED_RR, an inheritance
other than explicit and inherit, and a priority outside 256 to 767, and
EINVAL for an invalid detach state. Here they threw, or stored any
policy, inheritance and priority.

sceAgcDcbSetWorkloadsActive writes an 18-dword IT_NOP packet (stream id, 64-bit workload mask) and sceAgcDcbSetWorkloadComplete a 12-dword one (stream id, workload id, 64-bit clear mask), following KytyPS5. Both return null for a null buffer, an unregistered or out-of-range stream, a workload id above 63, and for active a duplicate id or a count of 0 or above 63. sceAgcDriverRegisterWorkloadStream and sceAgcDriverUnregisterWorkloadStream now record the stream ids the DCB calls check.

sceAgcDcbSetWorkloadsActive and sceAgcDcbSetWorkloadComplete threw. They now write a plain two-dword NOP and keep no workload state.

On a PS5 (firmware 13.60) a user with every accessibility setting at
its default reads chat transcription 0, press-and-hold delay 0, trigger
effect 1, vibration 1, zoom 0 and zoom follow focus 1; all six read 0
here. A user who is not logged in returns 0x80960009 with or without an
output, as sceUserServiceGetAgeLevel does.

A title creating a socket with sceNetSocket sets its options with the BSD
setsockopt, which looked the descriptor up only among libkernel's own
sockets and returned EBADF. libSceNet now registers an option setter with
libkernel, as it does for close and select, and accepts SO_REUSEADDR,
SO_BROADCAST, SO_SNDBUF and SO_RCVBUF like libkernel's own sockets.
PPSA01289 (Sackboy: A Big Adventure) sets SO_BROADCAST on its UDP P2P
socket this way in UIpNetDriver::InitBase. The failure made every listen
fail, and the engine travelled back to its default map with ?closed,
reloading it about every two seconds behind the loading screen.

A libSceNet socket is a kernel descriptor on the console, so titles close it
with close(). libSceNet keeps its sockets in its own table, and libkernel's
close passed their numbers to the CRT, which reported an invalid parameter
and left the socket open. libSceNet now registers a closer with libkernel,
as it registers its poller for select. PPSA01289 (Sackboy: A Big Adventure)
closes its P2P socket this way each time it tears its network session down,
leaking one open socket per attempt.

On a PS5 (firmware 13.60) a null name returns INVALID_ARGUMENT first,
then a user id the console does not know returns 0x80960105 whatever
the buffer, and a buffer shorter than 17 bytes is zeroed before
BUFFER_TOO_SHORT is returned. Here an unknown user returned
INVALID_ARGUMENT and a short buffer was left untouched.

With SO_RCVTIMEO set, Winsock fails a receive that waits that long with
WSAETIMEDOUT, which native_error turned into ETIMEDOUT (60). sceNetRecv,
sceNetRecvfrom and sceNetRecvmsg on a datagram socket therefore failed
with 0x8041013C on Windows, where FreeBSD's sbwait returns EWOULDBLOCK
(35) to soreceive, Linux returns EAGAIN, and POSIX (XSH 2.10.16)
requires EAGAIN or EWOULDBLOCK when no data was received.
A datagram socket has no connection that can time out, so WSAETIMEDOUT
there only means that the receive timeout the guest set has expired:
report EAGAIN. Stream sockets keep ETIMEDOUT, since Winsock leaves a
connection in an indeterminate state after a timeout; TechnicalDebt
records that gap and the one for SO_SNDTIMEO.
On a PS5 (firmware 13.60) scePthreadAttrSetsolosched and
pthread_attr_setsolosched_np accept only 0 and 16; every other value
returns ENOTSUP and keeps the stored one. The SCE set and get calls
return EINVAL for a null or uninitialized attribute instead of throwing.

fopen opened its stream with _wfopen, which shares read and write
access but not delete access. While the guest held a stream open,
rename of its file failed with EIO and remove with EBUSY. POSIX rename
and remove work on open files, as on Linux and FreeBSD, and since
#3677 the descriptors sceKernelOpen returns share delete access.
fopen now creates the handle with CreateFileW sharing read, write and
delete, with the access and creation disposition of the mode, and
wraps it with _open_osfhandle and _wfdopen, keeping append mode. A
failed CreateFileW sets errno through the error mapping #3677 added to
libkernel's NativeOpen, which moves to libc as
WindowsOpenError_nid_no_patch so that both use it. freopen still
reopens through _wfreopen; TechnicalDebt records it.
With the f32 denormal field of FLOAT_MODE set to keep, v_cmp_X_f32 and
v_cmpx_X_f32 read a denormal operand as zero: NVIDIA, RADV and lavapipe
all flush denormals in their float compares. Compare the operands as
sign-magnitude integers instead, with NaN handled apart. Compares with
flushed denormals are unchanged. This matches RDNA2 (gfx1036) on 256
operand pairs per opcode, with f32 denormals kept and flushed.

On a PS5 (firmware 13.60) destroying a rwlock returns 0 even while it
is held, and leaves 1 in the handle; every later call on that handle
returns EINVAL until it is initialized again. A zero handle is
initialized on first use by the scePthreadRwlock calls too. Here a held
rwlock returned EBUSY, a destroyed handle became null and was silently
re-created by the next POSIX call, and the scePthreadRwlock calls threw
on a zero handle.

On a PS5 (firmware 13.60) sched_get_priority_max returns 767 and
sched_get_priority_min 256 for SCHED_FIFO and SCHED_RR; the two were
swapped. Every other policy, SCHED_OTHER included, returns -1 with
EINVAL instead of a range or a host exception.

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.
Resident Evil 4 (PPSA07411, #2776) and PRAGMATA (PPSA02530, #3043) stop
on the absent export with
what(): _ZN3sce4Json14InitParameter225setSpecialFloatFormatTypeENS0_22SpecialFloatFormatTypeE not implemented
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.

sceContentExportStart hands out positive session ids, at most 10 live
(SharpProspero MaxExecution), and sceContentExportFinish closes them.
sceContentExportGetProgress, sceContentExportCancel and
sceContentExportFromDataWithThumbnail take their Orbital signatures and
check the session. The host has no media library to export into, so
FromDataWithThumbnail throws before it calls either data callback, and
GetProgress and Cancel throw for a live session since no export ever
runs and their result for an idle session is unknown. An eleventh Start
and Term with live sessions throw.
Titles: Cult of the Lamb PPSA06465 imports GetProgress, Cancel and
FromDataWithThumbnail (#2686); PPSA21564 (#271) and Cyberpunk 2077
PPSA04029 (#266) import Start.
Sources: Orbital tools/ida/db_types.json (cc408367) for the signatures,
SharpProspero Interop/Content/ContentExport.cs (5dfdb4b0) for the
session model and MaxExecution, shadPS4 content_export.h (443f0224) for
the parameter and callback layouts.

End clears the init flag set by sceVoiceQoSInit and returns 0, so the
library can be initialized again. Before an initialization it returns
0x804E0901 (LIBVOICEQOS_NOT_INIT), as measured on a PS5 (firmware 13.60)
in #1407.
LEGO Horizon Adventures (PPSA14632) calls it at shutdown and Ghost of
Yotei (PPSA26344) calls it on its sceVoiceQoSInit failure branch.
