SnapAdreno 3985c26..79de60e (branch migrate-private):
adreno-kext: re-prepare evicted maps (ADRENO_RESIDENT_REPIN)
adreno-kext: skip write-back maintenance once coherency is verified
adreno-kext: add desktop build profiles
adreno-kext: drop the raw-offset task lookup from the re-pin log
adreno-kext: say which commit the desktop profiles reproduce
SnapI2CHID 9cd36f4..816aad8 (branch migrate-private):
input: add a desktop build profile
Every new kext feature stays behind its define; the default builds of
both kexts are unchanged section for section. The re-pin and coherent
kext code uses this repository's compat/adreno-resource-tail.h and
compat/adreno-coherent-skip.h.
SnapI2CHID 9cd36f4, SnapQCC2072 244d5c7, SnapAdreno 3985c26, SnapMetal 40a1864
and air2ir3 55865cc split their large files into ordered parts that compile
as one translation unit each. Object code is unchanged in every component.
The Adreno kext, the Metal plug-in, air2ir3, SnapI2CHID and SnapQCC2072 now
live in their own repositories in the Snapintosh organization, split with
their history (git filter-repo --subdirectory-filter). They are mounted
back at their old paths, so relative build paths in build.sh, the tools
and the includes are unchanged. The EL2 monitor, tools and docs stay in
this repository.
Validation: see the follow-up verification on a fresh recursive clone.
The live scanout is mapped as Device memory, where an unaligned access
is an alignment fault and therefore a kernel panic. Cursor spans start
at an arbitrary x, so they are only 4-byte aligned. For long spans
(the enlarged shake-to-locate cursor, about 1.4 KiB per row) the kernel
memcpy issues 16-byte stores that end up unaligned, and the guest
panicked with "Unaligned kernel data abort" in
AdrenoDisplay::presentGated.
ADRENO_PRESENT_LIVE_ALIGNED routes every copy that reads or writes the
scanout through adreno_display_live_copy. It keeps memcpy when both
ends and the length are 16-byte aligned (whole rows) and otherwise uses
naturally aligned 8- and 4-byte accesses. The gate defaults to 0;
build.sh enables it because the faulting copy is also in the baseline
cursor path.
Validation:
PASS tools/test-adreno-live-copy.c: 7616 offset/length cases match
memcpy
PASS gpu/adreno-kext/kext/build.sh, with locally generated 26A428
headers
PASS with the gate off, the deployed kext configuration links
section-identical to the previous kext (12/12 sections)
OBSERVED A16, macOS 26A428: with the gate on, the shake-to-locate
cursor no longer panics. The same gesture panicked without it.
NOT RUN full host suite; frame-time measurement
An EL2 monitor/hypervisor and toolchain that boots macOS 27 on the ASUS A16
(Snapdragon X2 Elite), with an Adreno Metal plug-in and IOGPU kext, and
air2ir3, an AIR to Mesa ir3 shader compiler.
