Decode DB_Z_INFO.MAXMIP and DB_DEPTH_VIEW.MIPID and render into the
selected level of a 64 KiB Z_X mip chain as a surface of its own, at
the level's offset and extent from ComputeElementMipLayout, as color
target mips do. Slices of a mip chain step by the size of the whole
chain. Multisampled depth mips, other swizzles, levels in the packed
mip tail and HTILE on a mip chain still throw. LEGO Builder's
Journey (PPSA05496) stopped at its first scene on
"depth mips (DB_DEPTH_VIEW MIP_LEVEL) is unsupported".
A destroy waited only for another thread's render, so destroying a rack
that another thread had locked freed it under that lock. Destroys now
wait like renders and rack locks do, and the render owner field that
only those waits read is gone.

soreceive_generic keeps a MSG_WAITALL receive on a stream socket waiting until
the buffer is full, the peer closes or an error occurs. The three calls failed
every flag but MSG_PEEK and MSG_DONTWAIT with EOPNOTSUPP. A stream socket now
passes the flag to the host receive; a datagram socket ignores it, as a record
is delivered whole.

A relocation or lea target outside the unwind functions of a PS4 image
is now decoded up to its first jump, return or trap, or to the start of
the next unwind function, which also bounds the transfer check of the
tail rule. A target whose run holds an fs:[disp32] access, the form the
linear TLS sweep roots, is followed as code. The other targets taken as
data are counted in one message and kept as entry points that the
Windows TLS rewrite may not overwrite. The analysis merges nested
unwind ranges like the scans.

The skip of syscall patterns outside the unwind functions let some real
syscalls through. The scan now merges nested and overlapping unwind
ranges with the instruction scanner's MergeCodeRanges, so a pattern
inside an outer function is refused. A constant syscall number is also
looked for in the bytes in front of the pattern, whatever alignment the
decoding took: a mov eax, mov rax or xor eax, eax that ends at the
pattern or before register moves and zeroings that leave rax alone. The
decoded lookback requires each instruction to end where the next one
starts. Guest modules without PT_SCE_DYNLIBDATA get no unwind ranges,
so their scan stays strict even when their unwind table is read.

Rack locks and renders were tracked per system, so a voice callback
that locked a rack of another system could deadlock with that system's
render, or with a thread holding rack locks in both systems. Rack locks
and renders now exclude each other across threads and systems, as the
single internal lock did, while a thread nests them and other calls go
ahead.

The code analysis of the Windows and macOS outputs followed every
relocation and lea target inside the code range as code. PS4 images keep
read-only data between unwind functions, and strings and tables there
decoded into garbage, failing the conversion. Outside the unwind functions
such a target is now code only when it is 16-byte aligned, starts less
than 256 bytes after an unwind function and decodes to a jump, return or
trap; lea targets go through the same rule instead of the graph's own.

In a payload process on a PS5 (firmware 12.70), sysctlbyname returns -1
with ENOENT for thirteen names that threw here, and leaves the buffer and
the length alone, for a read, a size query, a null length and a null
buffer with a null length. sysctl does the same for the fixed MIBs of
seven of them. sysctlnametomib gives those seven MIBs and returns ENOENT
for hw.cacheline_size and hw.usermem, which threw too.
machdep.cacheline_size already returned ENOENT and is now tested with
the others. A write to the new names and MIBs throws, as the console's
answer to a write was not tried. The hw.realmem and vm.overcommit debt
entries now say that a payload process gets ENOENT for them as well.

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.
