The firmware's shared system option validator checks the size and the
fields from +0x6c on, not flags at +0x68. Rise of the Ronin (PPSA04540)
creates its system with flags 2, which threw. Accept and ignore bit 1;
every other bit still throws, now naming the value.
sceAgcSetAmmSemaphoreMemory and sceAgcGetSemaphoreLabel return the
firmware's errors instead of throwing, registration clears the whole
memory, and sceAgcSetSemaphoreMemory shares the registration with its
1 GiB size limit.

Host logging opens its own FILE on the saved descriptor. The guest FILE stays on the replaced descriptor, so guest printf, puts and fprintf still reach the pipe.
sceAgcAcbSetWorkloadsActive, sceAgcAcbSetWorkloadComplete and
sceAgcAcbSetWorkloadStreamInactive build the same packets as the DCB calls,
and sceAgcDcbSetWorkloadStreamInactive writes a 9-dword IT_NOP with the
stream id, the size of the console's user-data packet. The debt entry now
records the console layout read from libSceAgcDriver.

Follow FreeBSD 11's do_sem_wait and do_sem_wake (COMPAT_FREEBSD9/10) on
a struct _usem: a wait sets _has_waiters, returns at once while _count
is non-zero and otherwise sleeps on the semaphore's queue; a wake clears
_has_waiters when one waiter is left and releases one waiter.

On RDNA 2, an S# with TRUNC_COORD 0 rounds the scaled coordinate to 8
fractional bits, ties to even, and one with TRUNC_COORD 1 truncates it,
for point and bilinear filters. The S# decoder ignores the bit, and
AMD's Windows driver truncates for nearest samplers and rounds for
linear ones, so a TRUNC_COORD 0 point sample just below a texel edge
reads the texel below it. The code comment said the bit moves texel
selection by half a texel at most; the debt entry records the measured
rule instead.

Capture evaluated every flattened scalar slot even when a clean scalar
branch skipped it, so an inaccessible direct user-data root refused the
draw. Record flat-slot uses on resource control-flow blocks and evaluate
only the reachable ones; keep refusing taken and unresolved paths.
Fixes#8272.
Implement sceRudpPollCreate, sceRudpPollControl, sceRudpPollWait and
sceRudpPollDestroy with the PS Vita signatures and argument checks.
sceRudpTerminate removes the context from every poll and sceRudpEnd
destroys the polls and wakes their waiters.

scePsmlMfsrGetDispatchMfsrPacketSizeInDwords, scePsmlMfsrGetMipmapBias,
scePsmlMfsrSelectConfig, scePsmlMfsrRequestCapture and
scePsmlMfsrIsCaptureInProgress gain real signatures and semantics reversed
from the fakelib/libScePsml.sprx bundled with PPSA20397, which imports the
first three. The context records the input dimensions at creation so the
mipmap bias can be computed.
readdir and readdir_r returned d_fileno 0 for every entry on Windows,
because MinGW's _wreaddir reports no inode. FreeBSD 11.4's
_readdir_unlocked (lib/libc/gen/readdir.c) never returns an entry whose
d_ino is 0, and d_fileno is the number lstat reports as st_ino.
The Windows directory stream now reads the listing from the directory
handle with GetFileInformationByHandleEx(FileIdBothDirectoryInfo), so
each entry carries the file ID of the entry itself, symbolic links
included, without opening it. The ID is folded as stat and lstat fold
nFileIndexHigh:nFileIndexLow; the fold moves to WindowsDescriptor.hpp so
both libraries use it. rewinddir restarts the scan, telldir and seekdir
count entries as _wtelldir and _wseekdir did, and opendir fails with the
open error of the directory. A file system that lists no file ID gets a
nonzero number hashed from the name. Linux truncates the host inode to
32 bits as stat does instead of reporting 0 above 2^32.
guest_directory checks that every entry has a nonzero file number, that
the numbers of a file, a subdirectory and symbolic links to both equal
lstat's st_ino, that an entry created or removed while the directory is
open shows up after rewinddir, that a delete-pending entry no lstat can
open is still listed, and that seekdir returns the same number.
The initial import of a multisampled DCC target required its CMASK to be
uniformly 0xcc or the fully expanded code. When CB_COLOR_INFO enables
COMPRESSION but not FAST_CLEAR, the CMASK only holds FMASK compression,
which picks the fragment each sample reads, and a uniform DCC clear sets
every fragment to the clear color. The CMASK is then not checked, and the
target imports as the DCC clear.
METAL GEAR SOLID 4's launcher (PPSA18194) opens its Master Book on a
2-sample 1920x1080 target whose DCC reads as the 0000 clear and whose
CMASK holds stale bytes, with FAST_CLEAR off. It stopped there.

macOS fails a host path of 1024 bytes or more with ENAMETOOLONG, and the
host form of a guest path is the root directory followed by the guest
path, so a guest path of 1023 bytes, which FreeBSD accepts, fails there
under any root directory. guest_path_name_length skips that check on
macOS, and a debt entry for guest path names gives the macOS limit.
