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 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.
