LibwuIonIBw registers video out event id 16, which the host never triggers because its VRR state does not change; kP2L8t3j-aM returns 0 without effect.
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.
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.
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.

PPSA01289 (Sackboy: A Big Adventure) calls sceAudioOut2MasteringTerm when it
replaces its world, which threw. Like Init and SetParam it has no effect, as
there is no mastering stage. The title creates its next world's audio device
before it destroys the previous one, so Init runs twice before Term runs
twice; whether the console reports an error for either is unknown, so both
return 0 and the case is recorded in TechnicalDebt.

sceSystemServiceKillApp now ends the title as guest exit() does, so driver calls that wait for the exit park instead of throwing ProcessShutdown, and a second exit waits for the first. The test now fails when the kill returns, exits with a status other than 0 or bypasses the coordinator, and checks why a rejected call throws.
Report an app ID for the running title from sceSystemServiceGetAppIdOfRunningBigApp, and shut the guest down and exit when sceSystemServiceKillApp receives that ID with the arguments -1, 0 and 0. SwanStationPS5 (PPSA98510) 1.0.6 closes itself this way and stops on both imports on main.
EVO-PLAYER (PPSA99039) creates resident AVC, HEVC and VP9 decoders at
start-up, and stopped at "Videodec2: unsupported codec" on the HEVC one.
Codec types 974921 (HEVC) and 2382845 (VP9) now open FFmpeg's HEVC and
VP9 decoders. HEVC input goes through the same Annex B conversion as
H.264 and VP9 frames are passed through; output stays 8-bit NV12, and a
frame deeper than 8 bits throws. Picture info throws for HEVC and VP9,
whose layouts differ from the AVC one.

Capturing a shader threw "null or misaligned address" when the flat
SRT walk read through a pointer loaded from memory that is null or
unmapped, even when the program skips that s_load. Such a read now
yields zero and a record with its pc and address, as does a slot whose
address needs it. The registered artifact checks one flag word per
guarded slot at each ReadConst; the capture appends the flags and the
records to the flattened SRT, and a set flag raises an Unmapped BDA
fault through the fault buffer and stops the invocation as a BDA read
does. Nothing per capture enters a key: poisoned and clean captures
share one variant and specialization. Descriptors, branch conditions,
uniform fills, table bases and user-data pointers that need such a
value still throw, and poisoned results stay out of the dispatch and
draw caches. The shader disk cache format becomes 21.
Measured on RDNA2 in #697: an invalid product or sum (inf * 0, inf - inf)
gives the negative default NaN, 0xffc00000 or 0xfe00, and beats a NaN
addend. A NaN delta, then a NaN coordinate, still wins, quieted; a NaN
addend is returned quieted only when the product is valid.

Measured on RDNA2 in #697: v_interp_p1ll_f16 and v_interp_p1lv_f16 are a
fused multiply-add rounded once to f32, and v_interp_p2_f16 rounds the exact
P20 * J + S2 once to f16. The separate multiply and add matched about 85% and
4% of the measured rows.
Both steps now use FPInterpolateF32 and FPInterpolateF16: the f16 delta times
the f32 coordinate is exact in f64, the sum is rounded to odd and then once to
nearest even at the target precision, so no driver can split or reround it.
Infinite and NaN operands take the unbounded f64 result.

Decode the three VOP3 16-bit interpolation instructions (attribute, channel
and high-half select in the src0 field, the I/J VGPR in src1, P0 or the first
step's result in src2) and translate them with a new
GetInterpolationParameterF16 IR value. It reads the selected 16-bit half of
each vertex's parameter through VK_KHR_fragment_shader_barycentric, so P10 and
P20 are vertex differences rounded to f16; both steps are a multiply and an
add, as in the f32 forms.
An input in FP16_INTERP_MODE whose low half is defaulted is still declared at
its slot when its high half is read, and the high half takes its default from
USE_DEFAULT_ATTR1 and DEFAULT_VAL_ATTR1. Without barycentrics, on an input
without FP16_INTERP_MODE or on a pass-through input the instructions throw.
