From: Shawn Guo <shawn.guo@xxxxxxxxxx> Changes for v5: - Use crtc->state->plane_mask to check which planes are active for a given CRTC, so that we can save vou->overlays pointer array. - Use plane->state->crtc to determine if a plane is enabled or not, so that 'enabled' flag in zx_plane can be eliminated. 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 drivers/gpu/drm/zte/zx_plane.c | 328 +++++++++++++++++++++++++++++++----- drivers/gpu/drm/zte/zx_plane.h | 12 +- drivers/gpu/drm/zte/zx_plane_regs.h | 51 ++++++ drivers/gpu/drm/zte/zx_vou.c | 173 ++++++++++++++----- drivers/gpu/drm/zte/zx_vou.h | 3 + drivers/gpu/drm/zte/zx_vou_regs.h | 18 ++ 6 files changed, 503 insertions(+), 82 deletions(-) -- 1.9.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
