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.
A fill that covers a depth surface's whole stencil plane with four equal
bytes, or its whole depth plane with a value in 0.0-1.0, now reaches the
host image through the pending fast clear the next time the surface is
bound, sampled or stored to. An HTILE fill or HTILE clear kernel noted
afterwards replaces the value with DB_DEPTH_CLEAR/DB_STENCIL_CLEAR.
NoteDepthMetadataFill only reacted to fills of DB_HTILE_DATA_BASE, so the
Cohtml UI of Heretic + Hexen (PPSA26525) and DOOM + DOOM II (PPSA21444),
which resets its stencil plane to 1 with a 0x01010101 fill every frame and
then draws with stencil Equal 1 and 2, kept the stencil of earlier frames
and showed black squares and clipped text. agc_driver_depth_plane_fill
pins the rules.
Cult of the Lamb (PPSA06465, #2686) stops at start-up on the first one:
FAIL: unresolved ELF import pXJh3aVk8Ks from libSceContentDelete.prx
Both exports have been on main without an implementation (#2740); the
call itself has not been observed yet.
Orbital (cc408367, tools/ida/db_types.json:541-542) and SharpProspero
(5dfdb4b0, Interop/Content/ContentDelete.cs:25-42) agree on the
signatures: a 64-bit SceContentSearchContentId and a UTF-8 path. The
content library is empty on the host, since libSceContentExport exports
nothing into it, so no id or path can be found. SharpProspero gives only
NoPermission (0x809D5006) and no public source gives the not-found code,
so both calls throw with the id or path named once the null path and the
initialization are checked, like the "not in the host content library"
throws of #3724. sceContentDeleteById moves from
guest_content_unimplemented to the new guest_content_delete test.
NIDs pXJh3aVk8Ks and qC3QW+AltHs match tools/nid_names.py and the shadPS4
aerolib list.

(cherry picked from commit 928184824a4acdf36a58287034bff8154c861835)
On Linux, FIONREAD on a datagram socket reports the next datagram only,
where FreeBSD's sbavail counts every queued byte, so a read mark above 1
there could never fire. kevent now throws for it as before; stream
sockets and marks of 1 are unchanged.

The bundled PSNCore.prx of PPSA06888 calls sceNpTrophy2GetRewardIcon
with (context, handle, reward_id, buffer, size): once with a null buffer
to read the size, then with a buffer of that size. The function still
throws because the reward icon data is unknown.

Brings in main's connection verify options, minimum version, ALPN and
certificate readers. The conflicts in libSceSsl/Export.cpp and the
libSceSsl debt entry take the resolution from blawesom's rebase of this
pull request (blawesom/AnyPS5 rebase/6828 at 925c37aa0): SslConnection
keeps main's verifyOptions, minimumVersion and alpn next to the session,
and the debt entries follow main's structure.

kevent threw for NOTE_LOWAT. On a socket's EVFILT_READ it now sets the
low-water mark as FreeBSD 11's filt_soread does: the event fires once the
buffered bytes reach it, or at end of file or on a listening socket, and
a later change of the knote replaces it. EVFILT_WRITE takes a mark of 1,
where the host's writability stands in for a free byte; other write marks
and marks below 1 still throw. A pipe ignores the mark, as filt_piperead
does.

Metal Gear Solid 4 (PPSA18194) aborts on main when its launcher starts
the game: sceSystemServiceLoadExec runs the guest shutdown, a render
thread that then calls into the stopped AGC driver gets ProcessShutdown
back from LibcAwaitExit, and the exception unwinds into title code,
which terminates the process before the new executable starts.
LibcAwaitExit parks a thread only once an exit has been requested, and
LoadExec ran the shutdown without requesting one. It now starts the
shutdown the way exit does, so such threads wait until the process is
replaced.

StorageTextureBudget gave the storage image cache a quarter of the VK_EXT_memory_budget
budget of the largest device-local heap (capped at TextureCacheBudget, never below 512 MiB)
whatever else the heap held, while SampledTextureBudget takes what that budget leaves after
the heap's other use. On a 10 GB card the storage cache kept 2024-2170 MiB into a level load
whose depth and render target allocations then failed with VK_ERROR_OUT_OF_DEVICE_MEMORY
with the heap at its reported budget where a run logged it.
The storage image budget is now what the reported budget leaves after the heap's use other
than the cached storage images, the unused part of the sampled textures' 2 GiB floor and an
eighth of the budget; the caps at a quarter of the budget and at TextureCacheBudget and the
512 MiB floor stay. The sampled budget still reserves TextureCacheBudget for the storage
cache, at least the storage cap, and the storage budget reserves the sampled textures alive,
so neither counts bytes the other may take; while the sampled textures alive stay within
their floor the sampled budget falls first, then the storage budget, and above it both fall
together. The budget line also prints when the storage image budget moves by more than a
tenth, with its previous value, and StorageTextureCacheBudget is exported for the execution
test.

A socket's EVFILT_WRITE and sceKernelAddWriteEvent reported the whole SO_SNDBUF in data, however much was already queued. FreeBSD 11.4's filt_sowrite reports sbspace, the space still free. On Linux the queued bytes from SIOCOUTQ are now taken off SO_SNDBUF. Windows has no query for the queued bytes and macOS is not wired up, so both keep reporting SO_SNDBUF; the debt entry says so.
main d7262bd6d6 adds the single-sample scan entry after the custom MSAA
sample locations entry in the AGC debt file. Keep it after this
branch's version of that entry.

fcntl threw for F_GETLK with an F_UNLCK request on the hosts that use POSIX locks, as Linux's F_GETLK rejects that type. FreeBSD 11.4's kern_fcntl accepts it and lf_getlock reports the first overlapping lock that lf_blocks lets conflict: another owner's lock, one of the two being a write lock. For an F_UNLCK request that is exactly another owner's write lock, the same set an F_RDLCK request finds, so the host is asked with F_RDLCK and the reply is written back as for the other types.
fopen_s returned ENOENT for every failed open, including an invalid mode, a directory opened for writing and the loop and long-name cases. C11 K.3.5.2.1 only asks for a nonzero value; Microsoft's CRT, which shares Dinkumware's library, returns errno. fopen_s now returns the errno fopen set.
PPSA28997 (IL2CPP) calls sceLibcBacktraceGetBufferSize and
sceLibcBacktraceSelf. On Linux the host call stack is captured with
backtrace and each frame is resolved to its module and offset with
dladdr, then written as a linked list of frame records. The record
layout is inferred and listed in TechnicalDebt. Windows throws.
v_pk_add/mul/fma/fmac/min/max_f16 threw in f16 denormal modes 0-2. On
RDNA2 (gfx1031) bit 6 clear flushes each denormal input lane to a zero
of its sign, and bit 7 clear flushes an add result below 2^-14 and a
mul or fma result whose exact value rounded to 11 significant bits
with an unbounded exponent is below 2^-14, as the scalar forms do;
min/max flush only their inputs. Packed f16 still throws for f16
rounding other than nearest even.

On RDNA2 (gfx1031) f16/f64 denormal modes 0 and 2 flush the denominator
and numerator of v_div_fixup_f64 to a zero of the same sign and keep a
denormal quotient and result, as v_div_fixup_f32 does with the f32
field. The translation used them unflushed, so 0 / 2^-1074 gave 0
instead of the default NaN.
