By using shared drm helpers: 1. drm_gem_objects_lookup 2. drm_gem_(un)lock_reservations 3. drm_gem_shmem_helpers we can simplify lima driver a lot and benifit from updates to these functions.
drm_gem_objects_lookup need a refine in order to be used by lima.
Note: 1. changes to panfrost and v3d are just compile tested. 2. patch series is based on drm-misc-next branch
v2: Add drm_gem_objects_lookup_user and use it for driver which pass user GEM handles in contious array.
v3: improve commit comment.
Qiang Yu (6): drm/gem: refine drm_gem_objects_lookup drm/v3d: use drm_gem_objects_lookup_user drm/lima: use drm_gem_objects_lookup drm/lima: use drm_gem_shmem_helpers drm/lima: use drm_gem_(un)lock_reservations drm/lima: add __GFP_NOWARN flag to all dma_alloc_wc
