lchmod forwards to fchmodat with AT_FDCWD and AT_SYMLINK_NOFOLLOW, as
FreeBSD 11.4's sys_lchmod does. On Linux and Windows, which cannot change
the mode of a symbolic link itself, a symbolic link throws instead of
succeeding without a change.
An RX 6700 XT hands a geometry shader odd strip triangle i as
(i+1, i, i+2) with the last provoking vertex, which is the order the
translator already uses, and since #7374 last mode takes the flat
outputs of the program's primitives from their last index. Keep the
last-mode refusal for fans only, which reach the program as
(i+1, i+2, 0) while the hardware gives (0, i+1, i+2). TEKKEN DARK
RESURRECTION (PPSA31371) stops on such a strip draw.

sceCesRefersUcsProfile threw for every code page except 1250, 1251 and
1252. Twenty-seven more now return a profile that sceCesSbcToUtf8,
sceCesUtf8ToSbc and the MBCS context conversions accept: ISO 8859-1,
-2, -4, -5, -9, -10, -13, -14, -15 and -16, code pages 437, 737, 775,
850, 852, 855, 860, 861, 862, 863, 865 and 866, KOI8-R, KOI8-U and
Windows 1254, 1256 and 1258.
SingleByte.hpp holds the high half of each table, taken from the
public mapping files at unicode.org: ISO8859, Microsoft's PC tables,
VENDORS/MISC for KOI8 and Microsoft's best-fit tables for 1254, 1256
and 1258, the same source and derivation as the existing Cp1250 table,
whose high half equals bestfit1250's byte table. Bytes 0x00-0x7F are
unchanged in all of them, and every table maps its 256 bytes to 256
distinct BMP characters. The three existing profiles keep their
tables; one lookup now serves them all.
Profiles whose public table leaves bytes undefined (ISO 8859-3, -6, -7,
-8, -11, code pages 857, 864, 869), maps bytes to private use (874,
1253, 1255, 1257) or has no public table here still throw.
guest_ces checks that each new profile is a distinct, stable pointer,
four bytes per table against the source, a round trip of every byte
through sceCesSbcToUtf8 and sceCesUtf8ToSbc, UNASSIGNED_CODE for a
character outside the table, and a KOI8-R string through an MBCS
context in both directions.

sceAudioOutSetMainOutput threw "not implemented". In firmware 12.70
the export is `xor eax,eax; ret` (PS5-Audio-Passthrough-Research,
docs/FINDINGS.md line 25 at cf3c921): it reads no argument, changes
nothing and returns 0. It now does the same, defined in AudioOut.cpp
next to the Sys output calls.
Its parameters stay unknown and other firmware versions are
unverified. The debt file records this under Silent stubs, which
check_conventions requires for an export that returns a constant,
in place of the function's unknown-signature line.
The audio_out_sys test checks that the call does not throw and
returns 0; on main both checks fail.

_openat now opens files as openat does. It reads the mode argument only
when O_CREAT is set, as openat and _open do, and calls openat with the
same descriptor, path, flags and mode, so it returns the same
descriptors and errors.
The PS5 3.20 libkernel_sys export list (DNNDHH/PS5-3.20_Libs) has
_openat, NID bGVEgWXy6dg, as well as openat (A8Yk5AhNDck). In FreeBSD
11.4, _openat is the openat system call stub (lib/libc/sys/Makefile.inc,
amd64/SYS.h) and only libthr's openat adds a cancellation point
(thr_syscalls.c). openat here is not a cancellation point, so
forwarding to it leaves _openat without one, as in FreeBSD.
The openat debt entry now names _openat and no longer says that
O_NOFOLLOW is ignored: open, and so openat, has returned EMLINK for
O_NOFOLLOW on a symbolic link since 9421484572.
The kernel_sys test opens a file through a directory descriptor with
_openat and reads it back, creates one with O_CREAT, O_EXCL and mode
0600, checks outside Windows that it has mode 0600, reopens it for
writing, and checks EEXIST, EINVAL, EBADF and ENOTDIR.

The PS5 3.20 export inventory of libSceLibcInternal lists
__inet_ntoa_r next to inet_ntoa_r, and no AnyPS5 library exported it,
so a title importing it could not resolve it. It now runs inet_ntoa_r:
FreeBSD 11.4's arpa/inet.h names the function __inet_ntoa_r, and
inet_ntoa.c makes inet_ntoa_r a weak alias of it.
__inet_addr, __inet_aton and __inet_ntoa are in the same inventory,
but libc already exports them and the relinker also looks up
libSceLibcInternal imports in libc, so they are not added here.
guest_inet_address formats an address through __inet_ntoa_r into a
buffer of exactly the text's size, and checks that a buffer one byte
short is returned unchanged with ENOSPC and that inet_ntoa's buffer is
left alone.

Measured on firmware 13.60: registering an id outside 1 to 31 or one
already registered returns 0x8a6c0033, checked before a null stream,
which returns 0x8a6c0035; unregistering an id outside 1 to 31 returns
0x8a6c0033 and one that is not registered 0x8a6c003a.

A clean resident run was made read-only so that the next collect
could skip GetWriteWatch, and the first guest store into it was
resumed on the guest thread. The exception frame Windows builds for
that fault overwrites the System V red zone below rsp (#361), which
is what #5596 removed for singly mapped direct memory. Resident runs
are now never armed and are collected with GetWriteWatch only.

Measured on firmware 13.60: a start whose rounding to 16 KiB overflows
finds nothing, and of two equal free ranges the lowest is returned.

Measured on firmware 13.60: an alignment that is not zero or a power of
two returns EINVAL before anything else; bounds with nothing between
them return ENOMEM, a negative start searches from the bottom, only the
start is rounded up to 16 KiB and the end is used as given; null outputs
are skipped; errors leave both outputs untouched.

sceNgs2RackCreate and sceNgs2RackCreateWithAllocator now return the firmware's errors for a custom rack whose buffer count is outside 1 to 4 or below the submixer's max_inputs, whose module buffer id is at or above the count, or whose submixer has more than 37 channels, and for the state sizes of the Gain, Reverb and PitchShift modules, the Reverb option size and word, and the PitchShift option word. Racks that pass these checks with one of these modules or Convolution, with more than one buffer, more than 8 channels or a submixer max_inputs other than 1 or 2 still throw, and so does sceNgs2RackQueryBufferSize for the rejected options.
Add the GBK (CP936) and EUC-CN profiles, their scalar conversions to

Implement sceCesSbcTo{Ucs2,Utf16,Utf32}* and their inverses, and the
UTF-16 and UTF-32 MBCS string conversions and length queries, on the
existing single-byte, CP932 and CP51932 profiles.

Measured on firmware 13.60: attribute 0x100 makes a flag openable by
name, and only such flags can be opened. Each open returns a new handle
on the same flag, which sceKernelCloseEventFlag releases. Closing a
creator handle and deleting through an opened one return EPERM. Two live
shared flags cannot share a name, names of 32 or more bytes return
ENAMETOOLONG, and a missing name returns ESRCH. After the creator
deletes the flag, an opened handle polls and waits with EACCES and sets,
clears and cancels with no effect.

fdfawef324 notes that current LLVM spills SGPRs into VGPRs it allocates like any other
register, so one window register can be an ordinary register early in a
program and hold spill lanes later. ReadLaneEliminator only followed a
spilled lane across M0-indexed window stores for slots never used as
ordinary registers, so RESIDENT EVIL 4 (PPSA07411) and LEGO Horizon
Adventures (PPSA14632) kept their reloaded descriptors as run-time
values and stopped. A known lane can only come from a v_writelane chain,
so keep it across a computed-index store instead; a constant-index store
of the slot still ends the spill. This is fdfawef324's suggestion on
#6277.
That such a store misses the spill cannot be proven for these programs,
so it is checked at run time where a replaced read depends on it: a
backward liveness over each slot and lane whose known value a replaced
read used puts a WindowLaneGuard before every computed-index store at
which that lane is live, and the guard records a WindowLaneSpill fault
when the store changes that lane of the slot. The driver reads the fault
buffer back for every program with such a guard and reports the dispatch
or draw as failed, so a broken assumption is no longer silent. This also
covers the pure spill slots main already folds.

The entry was twice the 1000-character limit, led with the behaviour
rather than the gaps, and named a title. It now lists what throws and
what is inferred first, and names no title.

Vulkan needs PointSize above zero. A PA_SU_POINT_SIZE of 0 without
USE_VTX_POINT_SIZE, and a PA_SU_POINT_MINMAX maximum of 0 with it, now
throw. With USE_VTX_POINT_SIZE the clamp's lower bound is at least the
smallest positive float, so an exported size of 0 or less, which a
clamp minimum of 0 lets through, is written as a positive value.

A point list routed through the vertex path was refused, and so was
PA_CL_VS_OUT_CNTL.USE_VTX_POINT_SIZE on it. OliSe Player (PPSA01153)
stops on the latter with two of its MilkDrop presets.
The vertex path now draws point lists as Vulkan points. The vertex stage
writes PointSize: the misc export's X clamped to PA_SU_POINT_MINMAX when
USE_VTX_POINT_SIZE is set, and the PA_SU_POINT_SIZE height otherwise.
The point state travels in the recompile request (version 31) and the
cache and draw keys. Non-square register sizes, inverted clamps, point
sprite texture coordinates and, without largePoints, sizes other than
one pixel throw.

Measured on firmware 13.60: create accepts attribute bits 0x1, 0x2, 0x10,

the match and clear fields; EPERM, ECANCELED and EACCES write 0 to the
result pattern.
