Merge v7.1-rc5 into drm-next

2026-05-28T07:58:36+00:00

Boris Brezillion needs the gem lru fixes 379e8f1ca5e9 ("drm/gem: Make
the GEM LRU lock part of drm_device") backmerged for drm-misc-next.
That also means we need to sort out the rename conflict in panthor with
the fixup patch from Boris from drm-tip.

drm/msm/dpu: invert the order of UBWC checks

2026-05-22T13:43:13+00:00

Unlike other drivers, the DPU driver checks for exact UBWC version,
making it hard to add minor versions if necessary. Invert the order of
UBWC checks, letting the DPU driver handle new minors transparently.

drm/msm/dpu: drop ubwc_dec_version

2026-05-22T13:43:13+00:00

Stop using ubwc_dec_version (the version of the UBWC block in the
display subsystem) for detecting the enablement of the UBWC. Use only
ubwc_enc_version, the version of the UBWC which we are setting up for.

drm/msm/dpu: use new helper to set ubwc_swizzle

2026-05-22T13:43:13+00:00

Use freshly defined helper instead of using the raw value from the

drm/msm/snapshot: fix dumping of the unaligned regions

2026-05-16T14:20:04+00:00

The snapshotting code internally aligns data segment to 16 bytes. This
works fine for DPU code (where most of the regions are aligned), but
fails for snapshotting of the DSI data (because DSI data region is
shifted by 4 bytes). Fix the code by removing length alignment and by
accurately printing last registers in the region. While reworking the
code also fix the 16x memory overallocation in
msm_disp_state_dump_regs().

drm/msm: Don't use UTS_RELEASE directly

2026-05-15T14:24:02+00:00

UTS_RELEASE evaluates to a static string and changes quite easily (e.g.
uncommitted changes in the source tree or new commits). So when checking
if a patch introduces changes to the resulting binary each usage of
UTS_RELEASE is source of annoyance.

Instead of using UTS_RELEASE directly use init_utsname()->release which
evaluates to the same string but with that a change of UTS_RELEASE
doesn't affect msm_disp_snapshot_util.o or msm_gpu.o.
