Subject: [PATCH 0/2] drm/imagination: Switch the GPUVM to immediate mode
Date: Sun, 11 Oct 2026 02:22:19 +0900 [thread overview]
Message-ID: <20261011-pvr-gpuvm-immediate-v1-0-5b298dfce4f8@gmail.com> (raw)
Switch the GPUVM to immediate mode, as a prerequisite for asynchronous
VM_BIND. A revised VM_BIND series will follow separately; v1 [1] is
linked only for context.
The switch also fixes an issue Sashiko reported on [1]: the GPUVA lists
of other objects are updated without holding their reservations [2].
Based on drm-misc-fixes (depends on 196d4d10c1b3).
Tested on BeagleY-AI with lockdep, KASAN and failslab enabled:
- All IGT imagination tests pass, including pvr_vm_map [3].
- The fail-nth reproducer in patch 1 no longer warns.
