Main's #6402 stores to image tables: a table with a written entry takes
the fresh path, as it does on main, and so does one without a sampled
table binding, whose entries the fresh path rejects. The shared place
step uses the binding as a pointer. Main's #6614 frees descriptor sets
from shared pools one by one, while this branch keeps only dedicated
pools, so both stay. #7101's bulk key read counts its unmapped-page
skips as unmapped, and its key words sit next to this branch's write
stamp and compared runs.
Main's #7101 reads a key buffer's words in one call where this branch
names the reason a narrowing is skipped. Keep main's bulk read and
count both of its unmapped-page skips as unmapped.
A kqueue descriptor is readable while one of its events is triggered and
is never writable or exceptional, as FreeBSD's kqueue_poll answers, on
both hosts. On Windows select threw for it, and on Linux its /dev/null
placeholder was reported readable and writable.
A descriptor that stops being a socket, a kqueue or a pipe during the
wait now fails the call with EBADF when it was closed and is selected
again with the rest of the timeout when its number was reused, as
FreeBSD's kern_select looks every descriptor up again in each pass,
instead of throwing. On Windows a host descriptor that is not a pipe
throws when select starts, before waiting.
Depends on #7139.

select takes descriptors 0 to 2 as a console title's terminal with no input: 0 is never readable and 1 and 2 are always writable. poll threw for them unless the host happened to attach a pipe, so the same title could select on its standard streams but not poll them. poll now gives the same answer, with POLLOUT, the one bit ttydev_poll reports for a writable terminal, for 1 and 2 and nothing for 0.
selscan asks a descriptor once, with the flags of every set it is in (POLLRDNORM for the read set, POLLWRNORM for the write set, POLLRDBAND for the exception set, plus POLLHUP and POLLERR), and marks each set whose flags the answer shares. A seeded random device's randomdev_poll narrows a request with POLLRDNORM to that bit and returns any other request whole, so in the read set it is readable and in no other set, and otherwise it is in each write and exception set it was asked in; select reported it readable and writable together and never exceptional. A regular file or directory went to the host poll, which on Windows threw; vop_stdpoll makes it readable and writable and never exceptional, which select now answers in process on every host, as poll does.
poll threw for /dev/random and /dev/urandom, which select already treats as ready. FreeBSD 11.4's randomdev_poll, once the device is seeded, narrows a request that has POLLIN or POLLRDNORM to those bits and returns any other request whole, POLLOUT and the band bits included. poll now answers that, and the test that relied on the random device throwing uses a kqueue descriptor, which poll still does not support.
poll threw for any descriptor that is neither a socket nor a pipe, so a title polling a file it also reads stopped there. FreeBSD 11.4 hands a vnode to VOP_POLL, and both vop_stdpoll and vop_nopoll return POLLIN, POLLRDNORM and POLLOUT of the requested events for every event poll accepts and never POLLPRI, POLLRDBAND or POLLWRBAND. A file, a directory or a file read from app0.zar now answers that without a host call. File::IsVnode tells such a descriptor apart from the host file type without throwing, so a host socket lent by libSceNet still reaches its own path.
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.

PPSA34015 (EA SPORTS FC 27) registers EVFILT_READ for descriptor 0 in a
new kqueue at start-up, ignores the result, and stopped with "kevent:
EVFILT_READ on a non-socket descriptor not implemented". A read event on
the host stream on descriptor 0 is now accepted and never triggers, as
select never reports descriptor 0 readable.
Shader registration and the shader ABI resolves run on the title's own
threads, which never bound a trace buffer, so their Shader.Register and
Shader.Resolve* scopes were missing from every trace and summary. Those
entry points now bind the calling thread as `title` with the 32,768-event
buffer the shader preparation threads use.

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.
AI-assisted: yes
An ITIMER_REAL or alarm expiry while SIGALRM is blocked is marked on the
pending set of sigtimedwait instead of throwing, as kern_psignal leaves a
blocked signal pending. sigwait, sigwaitinfo and sigtimedwait take it,
repeated expiries merge into one pending signal, and unblocking it runs a
guest handler on the unblocking thread or, with the default disposition,
exits the process with status 142 as FreeBSD's default action does.
The expiry rechecks the mask after marking the signal, so an unblock that
races it does not leave SIGALRM pending while unblocked, and TakePending
clears the bit with the value it read so one signal is taken once.
