[0/5] drm/udl: Convert to generic fbdev emulation

Message

Thomas Zimmermann Oct. 24, 2019, 2:42 p.m. UTC

This patchset replaces udl's fbdev code with the generic implementation.

The first patch fixes a bug that didn't trigger yet because the current
fbdev never unmaps the BO. Patches 2 to 3 add missing interfaces to the
udl driver. Patch 4 sets mapping flags. In the final patch, we remove a
lot of code and set a few helpers instead.

The patchset was tested by running the fbdev console, X11, and Weston on
a DisplayLink adapter.

Thomas Zimmermann (5):
  drm/udl: Clear BO vmapping pointer after unmapping BO memory
  drm/udl: Set drm_driver.gem_prime_mmap
  drm/udl: Add GEM object functions for free(), vmap(), and vunmap()
  drm/udl: Map BO memory pages in unencrypted mode
  drm/udl: Replace fbdev code with generic emulation
