kevent threw for EVFILT_WRITE on any descriptor that is not a socket. On the write end of a pipe it now follows FreeBSD 11's filt_pipewrite: data is the free buffer space, and once the read end is closed the event reports EV_EOF with data 0. Adding the event after the read end is closed fails with EPIPE, as in pipe_kqfilter. EVFILT_WRITE on the read end still throws, because FreeBSD's pipe ends are bidirectional and host pipes are not.
A voice callback runs with the internal lock released, so another
thread could lock the rack being rendered and the render then finished
it under that lock. sceNgs2RackLock now also waits while another thread
renders the rack's system, as it did when the rack lock was the
internal lock.

StorageTextureBudget reserved the larger of the sampled textures alive
and their 2 GiB floor. The sampled budget already reserves
TextureCacheBudget, at least the storage cap, for the storage cache, so
on an 8 GB card the two caches each kept the other's maximum: with
3936 MiB used outside the caches on a 7189 MiB budget and 49 MiB of
sampled textures, the storage budget came out at 306 MiB and sat at its
512 MiB floor while about 2.7 GB of the budget stayed free.
The storage budget now reserves the sampled textures alive and gives
room back as they grow, at its next read. Where they hold 2 GiB or more
the budget is unchanged.
On Windows, sceKernelPwrite, pwrite, sceKernelPwritev, pwritev and the AIO
write commands wrote at the given offset on a descriptor opened with
O_APPEND. FreeBSD's vn_write sets IO_APPEND for an O_APPEND regular file
whether or not an offset is given, the filesystem then writes at the end of
the file, and the file offset is left unchanged. Write at Windows'
end-of-file offset in that case, and gather a multi-buffer pwritev into one
write as writev already does.
StencilReplaySafe refused every program with usesDma, including pixel
shaders whose only BDA accesses are reads (Onimusha: Way of the Sword,
PPSA27836: one global load, then image and buffer reads). Replaying such
a shader per reference value is idempotent: its only side effect is the
first-fault record, a compare-exchange that keeps the first fault; a
fault is never retried but thrown by CheckFault, and replayed draws with
a BDA table already wait and check faults before publishing. Written-page
tracking exists only in programs with bdaWrites, which stay refused.
Compiled shaders now carry bdaWrites, and ShadersWriteMemory counts a BDA
page table as a memory write only for a program that writes through it.

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.
