[PATCH v4 0/3] Add overlay plane support for ZTE drm driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shawn Guo <shawn.guo@xxxxxxxxxx>

Changes for v4:
 - Instead of using val, return value directly for zx_vl_get_fmt() and
   zx_vl_rsz_get_fmt().
 - Fix typo of 'heigth'
 - Add 'enabled' in struct zx_plane to track layer enabling state, and
   check the state in zx_plane_set_update(), so that we can call
   zx_plane_set_update() unconditionally in the vou irq handler.

Changes for v3:
 - Let zx_plane be accessible from zx_vou driver, and so we can easily
   access all the data encoded in zx_plane with a drm_plane pointer.
   Thus, function zx_overlay_find_vl_idx() can be saved completely.
 - Refine the existing zx_plane driver a bit to support disable graphic
   layer, and make the support of overlay plane a bit easier, by sharing
   VOU layer setup and teardown functions between graphic and video
   layers.

Changes for v2:
 - Use clipped coordinates for overlay position calculation

Shawn Guo (3):
  drm: zte: make zx_plane accessible from zx_vou driver
  drm: zte: add .atomic_disable hook to disable graphic layer
  drm: zte: add overlay plane support
