Say that 0x80bc0002 is this library's sceImeDialogTerm result rather
than a SharpProspero claim, and that the exports still throwing are
declared with shadPS4's parameters except sceImeDialogForTestFunction.

_pthread_cond_timedwait fails an abstime with a negative tv_sec with EINVAL
before it looks at the condition variable or the mutex. pthread_cond_timedwait
took it as a deadline in the past and answered ETIMEDOUT.

A registered type-3 hull program holds the local and the hull part of a
tessellation draw in one binary, addressed through SPI_SHADER_PGM_LO_LS
(SH 0x148) with no SPI_SHADER_PGM_LO_HS: the local part runs on the lanes
below s3[7:0] and writes LDS, an s_barrier follows, and the hull part runs
on the lanes below s3[15:8] and may store the registers the local part
filled. The draw decode asked 0x148 for a type-5 local half, and
PPSA11386 (007 First Light) stopped in its level load with "registered
program refers to an incompatible shader binary type".
The draw decode now gives a registered type-3 program both the local and
the hull role and marks the tessellation configuration mergedHull. The
local stage only passes gl_VertexIndex and gl_InstanceIndex in a 16-byte
record. The hull stage runs the whole program, one invocation per output
control point: v2 and v5 come from the record of control point
min(gl_InvocationID, inputs - 1), v3 is the relative vertex id, and the
LDS becomes a per-control-point output array that a control point writes
in its own record and reads in any record of its patch after the barrier.
Registers live across the barrier stay in the invocation.
The hull stage of a merged program runs at one lane per invocation on
every device (HostSubgroupSize 1). Its lanes are gl_InvocationID, not host
subgroup invocations, so the s_cbranch_execz around the local part tests
the invocation's own lane. With the device's subgroup it took a subgroup
ballot, and lavapipe, whose subgroup stages lack the tessellation control
stage, rejected the draw ("subgroup capability 61 is unsupported for
shader stage 2").
The lowering refuses more input than output control points, LDS writes
outside the own record, reads outside the patch's records, barriers that
some invocations do not reach or that sit in a loop, reads or writes of
another lane's register, outputs beyond the device limits, and fetch
subroutines. Type 3 is prepared with its stage group like type 5 and
takes its float mode from RSRC1_HS. The hull user-data address (SH
0x102/0x103) is optional for a merged program: s[0:1] take it, unchecked,
when the draw sets it and are zero otherwise.
Both stages refer to one binary, so a draw lists each code and header
region once (AppendProgramMemory); a request's memory regions must not
overlap. An indirect draw's record words go into every program whose user
data holds the register, so the hull stage of a merged program reads
them too.
mergedHull is part of the recompile cache key, the draw decode comparison
and the request serialization (version 39).

sceImeDialogForceClose threw. It now closes a running or finished
dialog the way sceImeDialogTerm does, without writing the typed text to
the title's buffer, and returns NOT_IN_USE (0x80bc0107) when no dialog
is open. The behaviour follows shadPS4 and the error code is the one
SharpProspero lists for PS5. The ImeDialog guest test covers each case.

The hmd2s and hmd2n sweeps left 19 libSceHmd2 exports that either write
into their arguments or take a slot number rather than a pointer first.
A third probe called the writers with zero-filled and with 0xAA-filled
buffers, dumping every byte that changed, and the slot exports with a
first argument of 0, 1, 2, 3, 4, 5, 8, 16, 255 and -1. Before
sceHmd2Initialize, six writers put fixed bytes in their output (a 2 and
a zero byte; 0x2000 and 0x100 as 64-bit sizes; four floats; six or
twelve floats of 0 and 0.5 followed by 0x8a720003), and twelve exports
accept a slot of 0 to 1, 2 or 3 and answer 0x8a720009 above it, with
0, -1, 0x8a721002, 0x8a721003, 0x8a72002c or 0x8a72100f for a valid
slot. They are bound here, by NID, to 14 handlers with the measured
checks, returning their value while the library is not initialized and
throwing if sceHmd2Initialize ever succeeds.
The one export whose answer depends on the contents of an in-out
structure stays unimplemented and is described in the debt file.

The hmd2s sweep left 81 libSceHmd2 exports that answer 0x8a720008 to
all-null arguments but something else to zeroed buffers. A second probe
called each of them six times before sceHmd2Initialize, every argument
pointing at a zeroed 16 KiB buffer except one, to find which arguments
are the checked pointers. 62 exports answer 0x8a720008 exactly when one
of a fixed set of arguments is null and their all-present code otherwise:
48 check the first argument, 10 the second, 6 the first two, 2 the first
and third, 2 all six. They are bound here, by NID, to 18 handlers with
that many pointer parameters, each returning ParameterNull for a null
checked pointer and otherwise the measured code (0x8a720004 for 20 of
them, 0 for 11, 0x8a721002 for 10, -1 for 5, 0x8a720009 for 7,
0x8a72002c for 3, and 0x8a720003, 0x8a721003, 0x8a721010 and 0x800d0203
for the rest) while the library is not initialized, throwing if
sceHmd2Initialize ever succeeds.
Left out: 7 exports that write output and 12 whose first argument is a
handle or slot number rather than a pointer. The debt entries list every
NID with its aerolib name where one exists.

A sweep of the 281 libSceHmd2 exports on a PS5 (firmware 13.60), each
called from a payload before sceHmd2Initialize once with every argument
null and once with every argument pointing at a zeroed 16 KiB buffer,
found 127 that answer the same code both ways and write nothing. 125 of
them are bound here, by NID, to one handler per answer: 45 return 0, 16
return 0x8a720008, 15 return 0x8a720004, 12 return -1, 10 reprojection
exports return 0x8a72000b, 9 return 0x8a720002, 9 return 0x8a720009, 5
return 0x8a721002 and one each returns 0x8a72002c, 0x8a721003, 0x400 and
0x20000. Each handler returns its measured value while the library is not
initialized and throws if sceHmd2Initialize ever succeeds, because the
initialized behaviour is not measured; since b378541e79 it fails with
UnsupportedFeature here, so these are the answers titles get.
Left out: the export that returns a pointer-like value, the one answering
0x8a72000a (which sceHmd2Initialize also returns for some applications),
the exports that answer differently to null and to zeroed arguments or
write output, the 16 that crashed the probe, and the exports that main,
its aerolib name where one exists.

A signal that is ignored is forgotten when it is sent: the call succeeds
(sys/kern/kern_sig.c:2178-2187). That covers SIG_IGN and the signals whose
default action is SA_IGNORE, SIGURG, SIGCONT, SIGCHLD, SIGIO, SIGWINCH and
SIGINFO (kern_sig.c:205-240); SIGCONT stays pending while blocked. The guest
failed with EINVAL for every such signal that has no host equivalent.

Cleanup removed only the three directories, so a run that stopped between
creating the symbolic link and removing it left the link behind and every later
run failed at its creation with EEXIST. Cleanup now also removes the plain file
and the link, and the link name and plain file name moved to namespace scope.

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.

bind, connect and sendto looked the descriptor up before they looked at the
address length, so a descriptor that is not open hid an argument error.
FreeBSD 11.4 sys_bind, sys_connect and sendit run getsockaddr first
(ENAMETOOLONG, EINVAL, EFAULT) and only then look the descriptor up, so
these arguments are now answered first and EBADF only follows for a valid
address.
