[v2,00/11] drm: rework mmap() workflow

Message

Gerd Hoffmann Sept. 17, 2019, 9:23 a.m. UTC

Add mmap callback to struct drm_gem_object_funcs, which is supposed to
handle the vma setup.  It will be used by both normal fops->mmap (via
drm_gem_mmap_obj()) and prime mmap (via drm_gem_prime_mmap()).

For starters the shmem and vram helpers are switched over to the new
workflow, to show things in action for review.

Gerd Hoffmann (11):
  drm: add mmap() to drm_gem_object_funcs
  drm/shmem: switch shmem helper to &drm_gem_object_funcs.mmap
  drm/shmem: drop VM_DONTDUMP
  drm/shmem: drop VM_IO
  drm/shmem: drop DEFINE_DRM_GEM_SHMEM_FOPS
  drm/ttm: factor out ttm_bo_mmap_vma_setup
  drm/ttm: drop VM_DONTDUMP
  drm/ttm: add drm_gem_ttm_mmap()
  drm/vram: switch vram helper to &drm_gem_object_funcs.mmap()
  drm/vram: drop verify_access
  drm/vram: drop DRM_VRAM_MM_FILE_OPERATIONS
