A storage view of the depth plane that starts above slice 0 was refused. The
layered storage image already spans slices 0..last, and the view starts at its
base slice, so the refusal is dropped and only the slices from the base slice to
the last are copied in and out. The base slice joins the cache key.
DepthStorageDispatch stores through a view from base slice 2 and checks the
other slices stay untouched; it fails without the change.
DecodeInstruction returned before reading the ModRM of FF /3 and FF /5,
so a far CALL or JMP through a RIP-relative pointer had no RIP-relative
displacement. A stub that moved such a JMP copied the displacement
without relocating it.
The decoder was compared with iced-x86 (AMD decoding) over 3.99 million
encodings: every opcode of the legacy, 0F, 0F38 and 0F3A maps under 34
prefix combinations and the VEX 0F, 0F38 and 0F3A maps, each with 48
ModRM forms. Apart from this, it agrees on length, RIP-relative offset,
control flow kind and branch target for every valid Zen 2 instruction
except near branches with a 66 prefix, recorded as technical debt, and
kernel-only returns, which it treats as sequential.
Add the comparison's metadata as cases: one RIP-relative encoding per
opcode, map and immediate size, every FF /r form, and the branch forms
with their flow kind and target. The existing cases check lengths only;
a loop or jrcxz decoded as an unconditional jump passed the whole suite.
The export turned YNw9Xk5iNWo from an unresolved import into a stub that throws. Dreaming Sarah (PPSA02929) calls it during start-up and now aborts with "YNw9Xk5iNWo not implemented" about 2 s in. Reverting until the function is implemented.
Accept SCE_NGS2_CUSTOM_MODULE_ID_USER_FX (0x1d) on custom submixer racks alongside UserFx2 (0x1f). When configuring a custom rack voice, support voice control parameter SCE_NGS2_CUSTOM_VOICE_PARAM_USER_FX (0x40001d00) to install custom submixer UserFx callbacks with user data. Run legacy UserFx callbacks during custom voice rendering and update sample presence flags accordingly.
Fixes runtime abort in Void Terrarium (PPSA03061):
terminate called after throwing an instance of 'std::runtime_error'
what(): NGS2: custom module id 0x1d is not implemented
FATAL: abort() (SIGABRT)
Closes#5055
Titles run natively, so a host CPU without an extension that compiled Zen 2 code uses faults with an illegal instruction deep inside a title (#3719: SHLX, BMI2). libkernel now reads CPUID and XCR0 when it loads on Linux and Windows, logs the host CPU's extensions and throws, naming the CPU and the missing extensions, before any title code runs.
select now checks pipe descriptors on Windows with the readiness test poll
already uses, so a pipe next to a libSceNet socket no longer throws.
RetroArch (PPSA99169) selects on libmicrohttpd's wake-up pipe beside its
listening socket. guest_select now runs on Windows too.
