The guest process is assumed to run as root. Under FreeBSD's
sys_seteuid and sys_setegid, id 0 is then accepted without a privilege
check and changes no credential, so both return 0. Any other id would
change the effective credential, which is not modelled, and throws.
Part of #1578.
sceNpEAAccessInitialize and sceNpEAAccessTerminate resolve the NIDs
7CxI50-xlCk and pMxXhNozUX8, which shadPS4 names in np_partner.cpp. The
stubs still throw; only the names and no-argument signatures change.
Use INFINITY and NAN from <cmath> instead of a new <limits> include, and
list the TechnicalDebt entry beside the other NGS2 voice entries, so the
change merges cleanly with the pan, channel map and reverb changes.

The template allocated a fixed 4 KiB of LDS, so kernels with immediate
offsets past it could not run. --lds (Python lds) sets the group segment
size in bytes, up to 64 KiB, with 4096 as the default.

libSceVdecsw is the software H.264 decoder interface PPSA05684 uses for
its movies. Decoder creation, compute queues, memory queries, decode
input and output, AVC picture info, reset and finalize are implemented
with the layouts of shadPS4's vdecsw.h, checked against the title's
movie decoder, and decode through libSceVideodec2. The H.264 stream the
Videodec2 test uses moves to a shared fixture, and a guest test decodes
it through Vdecsw.
Uncharted: Legacy of Thieves Collection (PPSA05684) plays its movies through libSceVdecsw and stopped at sceVdecswQueryComputeMemoryInfo.
llvmpipe builds the high dword of the shader clock with a left shift by
32 (emit_clock in Mesa's lp_bld_nir_soa.c), so it is always 0 and
s_memtime and s_memrealtime wrap every 2^32 ns. A pass of
agc_driver_shader_clock whose two reads straddle a wrap failed with
"memtime: lane N went back from 4294921902 to 3823"; dispatching right
before the boundary fails every lane of that pass.
On llvmpipe compare the low dwords modulo 2^32, which stays correct if
Mesa fixes the shift. Other devices keep the 64-bit comparison.

PS5 titles pass a 0x230-byte SceAvPlayerInitDataEx: auto start is the
byte after debug_level at 0x74, nine 0x30-byte thread parameter blocks
fill 0x78-0x228 and the output video frame buffer count is at 0x228.
sceAvPlayerInitEx read both fields at their PS4 offsets: auto start at
0xa8 is the video decoder thread priority and the buffer count at 0xa4
lies in the audio decoder block. PPSA25063 (Poppy Playtime: Chapter 4)
sets every thread priority to 700, so its intro video started on its
own and stopped at once; it writes auto start 0 and starts playback
itself.
With this_size 0x230 or more both fields are read at the PS5 offsets;
smaller structures are read as before. The layout follows KytyPS5,
prosper, SharpProspero and sharpemu and is recorded in TechnicalDebt.
guest_avplayer builds a 0x230-byte structure with auto start 0 and
nonzero thread parameters, then with auto start 1, and checks when
playback starts and how many video buffers are allocated.

sceHttp2GetMemoryPoolStats, sceSslGetMemoryPoolStats and
sceNetGetMemoryPoolStats threw. PPSA16064 (Minecraft Dungeons II,
Unreal Engine) queries all three while its HTTP module starts, and
aborted there.
Each library now records the pool size given at sceHttp2Init,
sceSslInit or sceNetPoolCreate and reports it with a peak and current
use of 0: the offline Http2 and Ssl models and the host-socket Net
library allocate nothing from these pools. The layouts follow the PS4
SDK's *MemoryPoolStats structures. Net returns EBADF for an unknown
pool and EINVAL for a null output, like its other pool calls; Http2 and
Ssl throw for both, as their error codes are unknown. Terminating a
context or destroying a pool forgets its size.
sceHttp2SetResolveRetry, which the title calls next, accepts and
ignores its value like the other Http2 settings. The four Http2
WebSocket exports the title imports are added as unimplemented.
guest_http2, guest_ssl and guest_sce_net check the reported sizes;
guest_sce_net also checks the null-output and unknown-pool errors.
The unified and service entitlement info list requests and polls threw.
They now return SCE_NP_ERROR_SIGNED_OUT, like the consume requests in
the same library. Their signatures are unknown, so they stay declared
without parameters.
PPSA15657 calls the unified request during start-up and continues past
the error.

Sackboy: A Big Adventure (PPSA01289) imports nine functions that no library
exports, so eager binding fails before it starts.
- libSceVoiceChat: sceVoiceChatRequestLeaveVoiceChatGroup and
sceVoiceChatRequestDeleteVoiceChatGroup, offline requests like the other
sceVoiceChatRequest* calls
- libSceNpSessionSignaling: sceNpSessionSignalingGetConnectionFromPeerAddress,
a throwing stub; the signature is unknown
- libSceCdlgG2P, a new library: the six sceG2PDialog* functions, throwing
stubs declared without parameters
TechnicalDebt records the assumed and unknown signatures.
