On a PS5 (firmware 12.70), of the values 0, 1, 2 and -1,
pthread_condattr_setpshared accepts only 0 and leaves the attribute
unchanged otherwise. pthread_condattr_getpshared reports 0 and returns
EINVAL for a null, uninitialized or destroyed attribute, also with a
null output. With an initialized attribute a null output crashes the
console; here it throws.

Measured on a PS5 (firmware 12.70): the getter reports 0, and of the
values 0, 1, 2 and -1 the setter accepts only 0 and checks the value
before the attribute. A null or uninitialized attribute, or a null
output, crashes the console; here it throws.

On a PS5 (firmware 12.70), of the values 0, 1, 2 and -1,
pthread_spin_init, pthread_barrierattr_setpshared and
pthread_mutexattr_setpshared accept only PTHREAD_PROCESS_PRIVATE (0);
1, 2 and -1 return EINVAL and leave the attribute unchanged.

Color format 7 (COLOR_11_11_10, float) keeps its 10-bit component in the
low bits; with the reversed component order (COMP_SWAP 2) that is blue,
with red in the high 11 bits. Vulkan has no such layout, so the target was
refused at decode.
Render it the way 10_11_11 unorm targets are rendered: an R32_UINT
attachment, the reversed export mapping 0xc6, and a new
ColorExportPacking::Float11_11_10 that makes the pixel shader pack each
export with the format-43 image store conversion (toward zero, overflow to
the largest finite value, negatives to zero, NaN kept). Blending, partial
writes, 16-bit integer exports, DCC and the other component orders throw.

sysarch's AMD64_GET_FSBASE, AMD64_GET_GSBASE and AMD64_SET_GSBASE now
follow FreeBSD 11's amd64 sysarch on Linux x86-64 through arch_prctl: the
GS base is the calling thread's, a base at or above VM_MAXUSER_ADDRESS
returns EINVAL and a null argument EFAULT. AMD64_SET_FSBASE, whose base
guest and host code share for their TLS, other operations and other hosts
still throw. Wine sets its TEB this way.

The binding plan refused every buffer atomic through a V# whose base is
not a multiple of 4. On RDNA2 such an atomic works when base + offset is
on a DWORD boundary and stops the dispatch otherwise, which the runtime
buffer atomic already does, so the refusal is dropped.

sceVideodec2Decode threw when it followed sceVideodec2Flush without
sceVideodec2Reset. It now resets FFmpeg's drained decoder and decodes the
unit, keeping the pictures the flush has not returned yet.

The generated rect-list control stage gave every corner of a rectangle the
flat inputs of its first vertex, so last mode was refused for rect lists.
BuildRectListShaders now also builds a control stage that takes them from
the rectangle's third vertex when the pixel shader has a flat input, and a
draw in last mode uses it.
