Subject: [PATCH v6 00/16] drm/msm: A couple lazy-vm fixes
Date: Fri, 17 Jul 2026 13:48:16 -0700 [thread overview]
Message-ID: <20260717204841.26120-1-robin.clark@oss.qualcomm.com> (raw)
The VM is created lazily to give userspace a chance to opt-in to
VM_BIND. But Sashiko noticed a couple paths that were not handling
this properly. Or at least that is how this series started out.
Rob Clark (16):
drm/msm: Fix barriers accessing ctx vm
drm/msm: Rework queuelock
drm/msm: Synchronize VM creation on ctxlock
drm/msm: Synchronize set_sysprof on ctxlock
drm/msm: Move nr_cmds initialization
drm/msm: Remove redundant SIZE_MAX check
drm/msm/a6xx: Access VM directly in submit path
drm/msm: Add helper to check for per-process pgtables VM
drm/msm/gem: Remove useless locking in GEM import
drm/msm/gem: Extract bookkeeping init helper
drm/msm/gem: Set resv before exposing obj
drm/msm/gem: Validate lazy VM in GEM_NEW
drm/msm: Allow lazy VM creation to fail
drm/msm: Don't fallback to shared VM for VM_BIND
drm/msm: Fix per-process-pgtables check
drm/msm: Fixup invalid overflow check
