drm/msm/a8xx: use pipe protect slot 15 for last-span-unbound feature 2026-05-29T14:07:30+00:00 Alexander Koskovich akoskovich@pm.me 2026-05-28T09:49:04+00:00 c2c083bbe07bd65f376d1ce7e136838427f494b1 A8XX GPUs have two sets of protect registers: 64 global slots and 16 pipe specific slots. The last-span-unbound feature is only available on pipe protect registers, and should always target pipe slot 15.
