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.
