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.

XPSemu (PPSA97358) queries RLIMIT_NOFILE at start-up in QEMU's
os_setup_limits and stopped on the unsupported resource. It reports the
descriptor count after which AnyPS5 fails with EMFILE: the C runtime's
8192 low-level descriptors on Windows and the host limit on Linux.

Detect HDR output on the host: on Windows the monitor showing the window
must run in HDR10 (DXGI IDXGIOutput6), and on every host the window's
Vulkan surface must offer a 10-bit VK_COLOR_SPACE_HDR10_ST2084_EXT
swapchain with VK_EXT_swapchain_colorspace and VK_EXT_hdr_metadata. The
monitor's luminance comes from DXGI; hosts that report none get 1000
nits peak and full frame, 0 nits black.
While HDR output is available, sceVideoOutGetOutputStatus reports
dynamic range 2 and flag bit 0, sceSystemServiceGetHdrToneMapLuminance
reports the monitor's luminance, and every open port's output mode
event fires when that changes. PQ display buffers are presented
unchanged through an HDR10 swapchain with HDR metadata; any other
display buffer switches back to the SDR swapchain. Without HDR output
the PQ to SDR conversion uses the peak the title was last told as its
white level.
AI-assisted: yes
Accept the 10-bit BT.2100 PQ display formats 0x8100070422000000 (red
in the low bits) and 0x8100070400000000 (blue in the low bits) and
convert them to 8-bit sRGB when presented: PQ EOTF, BT.2020 to BT.709
primaries, a luminance tone map whose white level is the tone-map
luminance sceSystemServiceGetHdrToneMapLuminance reports (reference
white min(203 nits, white level)), and the sRGB encoding.
The conversion runs on the CPU for linear buffers and DCC clear values,
in the color transfer shader for tiled guest buffers, and in the
presentation pass for resident images. The three share the PQ EOTF
table computed once in double precision.
AI-assisted: yes
An unterminated or empty directory name, "." or "..", or a name
containing "/", "\" or ":" now returns SAVE_DATA_ERROR_PARAMETER and
leaves the mount result unchanged. The SDK 12.000 reference lists that
code for an invalid parameter of sceSaveDataMount3, KytyPS5's
SaveDataMount3 returns it for an invalid name, and sceSaveDataDelete
and sceSaveDataConvert already return it here for the same check.
It threw before, which stopped Minecraft Preview (PPSA19639) on
entering a world.
The Mount3 trace now prints at most the 32 bytes of the directory name
and the 16 bytes of the mount point, since both can be unterminated
when the mount fails.

On Windows every direct host import leaves the write watch, and a storage
image over it compares its whole surface with its guest-byte copy at every
collect epoch. #4432 measured 7-8.6 s of every 10 s in those compares on a
GTA V scene, with 98% of the compared surfaces unchanged.
Tracker blocks that leave the watch now keep their write-watch marks as a
hint. Leaving the watch gives a block a fresh hint stamp, and
UntrackedHint walks a range of such blocks, at most once per collect epoch
and thread, stamping the blocks whose pages a CPU store marked; it
returns the newest stamp of the range. compareUntracked puts that stamp in
its memo key in place of the collect epoch, so an image is compared again
after a mark in its range, a driver store, a mapping change or a recorded
GPU write. The byte compare still decides whether anything changed: a mark
the driver makes without a CPU store costs one compare and drops nothing.
Nothing else reads the hint. Collects, Watched, UnchangedSince,
ChangedBlocks and NewestStamp still treat those blocks as untracked, and
Linux is unchanged.
agc_driver_dcc_keys_first_write refreshes an imported storage image over
50 collect epochs with no store: it compared the image 50 times before and
0 times now. A CPU store is still uploaded on the next refresh, and a store
of the bytes already there costs one compare and keeps the pending
results. agc_write_tracking checks the hint itself.
