Message

Jason-JH.Lin Oct. 27, 2021, 2:18 a.m. UTC

These refinements include using standard mailbox callback interface,
timeout detection, and a fixed cmdq_handle.

Change in v5:
1. Move mbox_free_channel to a independent patch.

Change in v4:
1. Add cmdq_vblank_cnt initial value to 3.
2. Move mtk_drm_cmdq_pkt_create to the same define scope with
   mtk_drm_cmdq_pkt_destroy.

Change in v3:
1. Revert "drm/mediatek: clear pending flag when cmdq packet is done"
   and add it after the CMDQ refinement patches.
2. Change the remove of struct cmdq_client to remove the pointer of
   struct cmdq_client.
3. Fix pkt buf alloc once but free many times.

Changes in v2:
1. Define mtk_drm_cmdq_pkt_create() and mtk_drm_cmdq_pkt_destroy()
   when CONFIG_MTK_CMDQ is reachable.
