#1398 and #1399 both rewrite the sceRtcParseDateTime entry that the s_sethalt entry followed. It now follows the libSceAudio3d entries, which no open pull request edits, so either can merge first without a conflict.

#1372 adds its test after the vop1 decode tests and #1314 its debt entry after s_setkill, the places where this branch added its own. The wave control decode test now precedes the vop1 decode tests and the s_sethalt entry follows sceRtcParseDateTime, so either pull request can merge first without a conflict.

s_sethalt with SIMM16[0] clear is a no-op; s_sethalt 1, s_sendmsghalt, a reached s_code_end, s_rfe_b64, the ds_gws_* instructions and ds_ordered_count throw with the reason at translation. Linear decoding stops at s_code_end like at s_endpgm, so code padded with s_code_end after a final backward branch decodes. Encodings from LLVM SOPInstructions.td and DSInstructions.td, checked against the gfx10 MC tests; semantics from the RDNA 2 ISA guide.
DecodeState and the draw precheck rejected DB_SHADER_CONTROL bit 16,
PRIMITIVE_ORDERED_PIXEL_SHADER (POPS), which runs the ordered section
of overlapping pixels' shaders in primitive order. The bit now reaches
the recompiler as a pixel stage field, and such a pixel shader declares
PixelInterlockOrderedEXT and runs its whole body between
OpBeginInvocationInterlockEXT and OpEndInvocationInterlockEXT; an
invocation that a BDA read fault kills ends the interlock first. The
POPS collision SGPRs read 0, so a title skips its POPS wait and runs
its per-collision loop once. An image_load still reads a sampled
binding, which misses an earlier overlapping primitive's image_store in
the same draw. The device enables VK_EXT_fragment_shader_interlock when
it has fragmentShaderPixelInterlock; without it the recompile throws,
as does a nonzero POPS_OVERLAP_NUM_SAMPLES. The field is part of the
recompile cache key, the draw key and the serialized request (version 10).
SHA-1 and SHA-256 instructions with a [rip+disp32] operand, and
instructions with one that a short site absorbs, now move into the
stub. The stub records each displacement as a relocation relative to
the site, and the Linux, guest and Windows placements resolve it once
the stub address is known. Indirect branches through [rip+disp32]
still fail the relink.

Use the shared atomic bounds check instead of wrapping at 64 KiB.
Expect zero returns and unchanged LDS for aligned out-of-range accesses,
and record the gfx1035 hardware measurements.
No request reaches the network, so sceHttpsSetSslVersion has no TLS
connection to configure, sceHttpSetRedirectCallback and
sceHttpSetCookieRecvCallback register callbacks that are never called,
and sceHttpsGetSslError reports error 0 with detail 0. A null errNum or
detail returns SCE_HTTP_ERROR_INVALID_VALUE like sceHttpGetLastErrno.
Signatures follow shadPS4.

Opening a volume needs administrator rights, so the volume flush skipped
every volume in a normal user session. The libc, libkernel, save data and
app content file functions now record each host file and directory they
change. On Windows sceKernelSync flushes the recorded paths that changed
since the previous call, plus their changed parent directories, through
handles a normal user can open. Linux still calls sync().
wcstod, wcstof, wcstold, wcstol, wcstoll, wcstoul, wcstoull, wcscoll and wcsxfrm still forwarded to the host's wchar_t functions, which use 32-bit units on Linux. The wcsto* functions now parse the ASCII prefix of the guest string with the narrow parsers, as the C locale accepts only ASCII white space and digits. wcscoll compares like wcscmp and wcsxfrm copies, as strcoll and strxfrm do in the C locale.
BnMAMrsfVWo is _ZSt19_Throw_bad_weak_ptrv. Replace the unknown stub
with a throw of a guest std::bad_weak_ptr, and add its type info,
vtable, destructors and what().

sceKernelReadv, sceKernelWritev, sceKernelPreadv and sceKernelPwritev threw on Windows. They now gather or scatter through one host buffer and issue a single read or write, with the same argument checks and error codes as the Linux path. Positioned transfers restore the file offset afterwards, as pread and pwrite do on POSIX, and report ESPIPE for handles that are not disk files. guest_file_vector now runs on Windows as well.

COPY_DATA rejected source select 9 (GPU clock count) and any cache
policy bits. PPSA16064 (Minecraft Dungeons II, Unreal Engine)
calibrates its GPU timer at start-up with a submission of five
COPY_DATA packets, control 0x06016209: GPU clock source, memory
destination, 64-bit count, source and destination cache policy 3. The
submission was rejected and the title aborted.
The clock source now writes the same counter as a RELEASE_MEM
timestamp (the host steady clock in 10 ns ticks), read when the packet
runs, through the direct execute path and through ResolveStore for
stores recorded on the GPU. A 32-bit count writes its low half. The
source and destination cache policy fields are accepted and ignored,
as for WRITE_DATA and DMA_DATA. The reference clock (source select 10)
and the other unimplemented sources still throw.
agc_driver_pm4 runs the title's packet twice and checks a nonzero,
non-decreasing counter and an 8-byte resolved store, and that source
select 10 is still rejected.
The guest's wchar_t is 16 bits, but wcslen, wcscmp, wcsncmp, wcscpy, wcsncpy, wcschr, wcsrchr, wcsstr, wcspbrk, wcsspn and the wmem functions forwarded to the host's wchar_t functions, which use 32-bit units on Linux. Implement them on char16_t. The wide conversions that still use the host's wchar_t are listed in TechnicalDebt.
NVIDIA (595.91.07) refuses VK_EXT_external_memory_host imports of
read-only or executable mappings with VK_ERROR_OUT_OF_DEVICE_MEMORY and
then fails every later vkAllocateMemory on the device. Check the range
is mapped read-write before importing on Linux, as the Windows path
already does for read-only memory, and copy it otherwise.
Refs #1022
A CMASK holds 4 KiB per 1024x512-pixel metablock, not one nibble per 8x8
tile of the target: 1920x1080 spans 0x6000 bytes, as titles clear it,
not 16200. The swizzled nibbles of the lower-right tiles lie past the
packed size, so the fast-clear check missed them and the expanded store
left them cleared.

The driver copies a submission's packets when it is submitted, but
SET_SH_REG_INDIRECT, SET_UCONFIG_REG_INDIRECT and SET_CONTEXT_REG_INDIRECT
read their (offset, value) lists from guest memory only when the queue
worker reaches the packet. A title that reuses its per-frame memory once
it expects the GPU to be done with it can rewrite a list in between, and
the worker then throws on the data it finds there ("extended register
semantics are not implemented (offset dword 0x3a888889)").
The lists are now read with the packets, after validation, in Submit and
for a rewind tail, and the worker writes the registers from that copy.
Pm4::Execute keeps reading the list itself for direct callers.
PPSA21402 (Balatro) keeps three frame slots and does not wait for the GPU
before reusing one: its slot labels start at 0xffffffff and the GPU only
ever writes 0xffffffff to them, so the poll before a slot is reused never
blocks. When the worker falls more than two frames behind, the title
writes per-draw constants over a SET_CONTEXT_REG_INDIRECT list the worker
has not read yet.
The console's PFP reads the list when it reaches the packet; the
difference is recorded in TechnicalDebt.md.
A color target with both DCC and CB_COLOR_INFO.FAST_CLEAR keeps its fast
clear in the DCC keys and fills its CMASK with 0xF (expanded), as radv
does (radv_get_cmask_fast_clear_value) and as PPSA21567 does
(CB_COLOR_INFO 0x10042730, reported on #419). Such targets now decode;
their clear is materialized by the existing DCC path. A DCC target's
CMASK that is not all expanded throws.

Draws into a color target with CB_COLOR_INFO FAST_CLEAR (bit 13) were
rejected. The CMASK keeps one nibble per 8x8 tile: 0 means the tile is
fast-cleared and reads as CB_COLOR_CLEAR_WORD, 0xF means expanded (the
texels hold the color). The texture units and display scanout do not read
it, so a title runs a fast-clear eliminate pass before sampling or
flipping such a target.
DecodeColorBuffer now takes the CMASK address (CB_COLOR0_CMASK and
CB_COLOR0_CMASK_BASE_EXT) and the bytes one nibble per 8x8 tile spans.
Before a draw renders into the target, and in a fast-clear eliminate
pass, a CMASK whose nibbles are all 0 is materialized: the target is
filled with the clear texel (FillClear on its resident image, else
guest memory on the CPU) and the CMASK bytes are stored as expanded,
through the same GPU-ordered store as the DCC "uncompressed" keys
(0xFF either way). The result equals the draw followed by the eliminate
pass. An all-expanded CMASK changes nothing; a mixed one throws, as do
fast clears of DCC, mipmapped, 3D and array targets.
PPSA14632 (LEGO Horizon Adventures) fast-clears its two 3840x2160
display buffers through CMASK, so its final composite draw was dropped
on every frame and only black was presented.
