The debt entry cited ARB_multisample's centermost-sample shortcut as
what a single-sample scan into a multisampled depth target draws. The
draw tests each depth and stencil sample with the depth at the pixel
center, which is the rule above that shortcut (L185-L190 and
L422-L425); the shortcut is now named as an unmeasured alternative.

A draw with PA_SC_AA_CONFIG.MSAA_NUM_SAMPLES 0 and MSAA_ENABLE clear
into a 4x depth target threw "the depth target's sample count differs
from the rasterizer's", which stops METAL GEAR SOLID: Peace Walker
(PPSA18216) at its first presentation. Such a draw now rasterizes the
depth target's sample count with every sample at the pixel center, as
a single-sample scan into a multisampled color target already does.
radeonsi programs this MSAA_ENABLE and PA_SC_AA_CONFIG with the depth
buffer's own sample count when GL multisampling is disabled, and GL
then gives full coverage with every depth and stencil sample set from
the pixel center.
Triangles and rectangles are accepted. Points, lines, alpha-to-coverage,
DB_EQAA Z interpolation or overrasterization, a pixel program reading
the sample index and a sample-mask export throw on this path, as does
a single-sample color target next to the multisampled depth target.
The primitive check is shared with the single-sample MSAA_ENABLE rule,
whose behaviour and messages are unchanged.

Implement sceSslGetSerialNumber, sceSslGetSubjectName, sceSslGetIssuerName, sceSslGetNameEntryCount, sceSslGetNameEntryInfo, and sceSslFreeSslCertName. Signatures follow VitaSDK. Mbed TLS extracts the certificate's serial number and X.509 subject and issuer distinguished names, extracting OID attribute short names (or numeric strings) and value strings.
sceSystemServiceParamGetInt answered 0 for the time zone (parameter 4)
and summer time (parameter 5), so the console looked set to UTC while
libSceRtc and libc convert local time with the host's zone. Titles add
the time zone in minutes and 60 more minutes when summer time is 1 to
UTC to get the local time (Apollo, GoldHEN's frame logger). Both now
follow the host's local time zone: summer time is whether it is in
effect, and the time zone is the current offset east of UTC less the
summer time shift while it is.
On Windows that shift is the C runtime's own summer time bias
(_get_dstbias), the one localtime_s applied, not a fixed 60 minutes.
The UCRT reads the system zone when libc.prx loads and keeps that
zone's bias after TZ is set later, so on a host whose system zone has
no summer time (the CI runner's UTC) a TZ of CET-1CEST shifted by 0 and
the time zone came out as 0. The cause and the change are screamm's,
from the review.

Implement sceNgs2GeomApply, which was previously an unimplemented
throwing stub and was blocking Dead Cells (PPSA15552).
The implementation validates null handles/output addresses and writes a
minimal Ngs2GeomAttribute: pitch_ratio 1.0, source position, source
volume/level maxima, and diagonal channel levels for the source's channel
count. It does not implement source attenuation, distance rolloff, panning
or Doppler.
The export lives in Geom.cpp's internal Ngs2GeomApply and is exposed through
the existing default-visibility wrapper in Voice.cpp. Unimplemented.cpp no
longer defines the stub. A passing test was added to Ngs2Geom.cpp.

Takes #6451's merge of main. Main's spanned-waves flag took request
serialization version 32, so the sample order moves to version 33; a
version 32 request keeps its spanned-waves flag and reads no sample order.
Multisampled color targets now gain storage usage on their first storage
binding; a target whose samples may be reordered still gets it at creation,
and the recorder's storage-usage checks expect that.
Main's one-sample target test expected a pattern varying between pixels
to be refused on a device without a one-sample 2x2 grid; with the grid
fallback it takes pixel (0,0)'s locations instead, so the test now
expects it to be accepted.
A one-sample target drawn by a multisampled rasterizer refused a pixel
shader that reads ANCILLARY with POS_X_FLOAT or POS_Y_FLOAT, because the
sample index made the host shade per sample and moved FragCoord from the
pixel centre. A shader the guest does not iterate now runs once per pixel
with sample number 0, and on this path the rasterizer keeps one sample, so
those draws are no longer refused. Resident Evil Village's (PPSA01556)
2x depth-only pass with SPI_PS_INPUT_ENA 0x2301 was one of them.
Main took request serialization versions 31 (output primitive size) and
32 (spanned waves), and #6683 uses 33, so the pixel iteration fields move
to version 34. A version 32 request keeps its spanned-waves flag and reads
no pixel iteration.
Main's #5905 settles Linux dma-buf imports with settleImport, which is
now built on both platforms. The batched settle of Windows imports under
1 MiB, its counters and adoptSettleDevice's batch reset stay Windows-only,
and ClearHostImports drains the batches only there.
