[v3,0/2] drm/udl: Map pages with SHMEM helpers

Message

Thomas Zimmermann June 9, 2020, 9:08 a.m. UTC

Udl implments cached mappings. Convert it to SHMEM's default helpers.

This version contains only style fixes. I'm posting v3 mostly for reference
before merging.

v3:
	* rebased onto Daniel's shmem untangle series
	* style fixes
v2:
	* keep writecombine mappings as the default
	* add SHMEM helper for creating BOs with cached mappings
	* update udl on the new helper

Thomas Zimmermann (2):
  drm/shmem-helper: Add .gem_create_object helper that sets map_cached
    flag
  drm/udl: Use GEM vmap/mmap function from SHMEM helpers
