[PATCH v3 0/6] drm/mediatek: fix cursor issue and apply CMDQ in MTK DRM

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

 



The CMDQ (Command Queue) in MT8183 is used to help update all
relevant display controller registers with critical time limation.
This patch add cmdq interface in ddp_comp interface, let all
ddp_comp interface can support cpu/cmdq function at the same time.

These patches also can fixup cursor moving is not smooth
when heavy load in webgl.

This patch depends on ptach:
add drm support for MT8183
(https://patchwork.kernel.org/cover/11121519/)
support gce on mt8183 platform
(https://patchwork.kernel.org/cover/11255147)
drm/mediatek: Refactor plane init/check and support rotation
(https://pw-emeril.freedesktop.org/series/69015/)
drm/mediatek: Check return value of mtk_drm_ddp_comp_for_plane
(https://lore.kernel.org/patchwork/patch/1154517/)

Changes since v2:
 - move some changes to another patch
 - disable layer in atomic_disable()

Changes since v1:
 - remove redundant code
 - merge the duplicate code
 - use async instead of cursor

Changes since v0:
 - remove redundant code
 - remove patch
   "drm/mediatek: fix atomic_state reference counting"
   After remove this patch, the issue we met before is gone.
   So I do not add any extra code to do something.

Bibby Hsieh (6):
  drm/mediatek: use DRM core's atomic commit helper
  drm/mediatek: handle events when enabling/disabling crtc
  drm/mediatek: update cursors by using async atomic update
  drm/mediatek: remove unused external function
  drm/mediatek: support CMDQ interface in ddp component
  drm/mediatek: apply CMDQ control flow
