Y_OFFSET field starts at bit 8 not 7. Signed-off-by: Eric Anholt <[email protected]> Signed-off-by: Boris Brezillon <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
This is needed to support X/Y negative placement of planes using T-format buffers. Signed-off-by: Eric Anholt <[email protected]> Signed-off-by: Boris Brezillon <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
drm_atomic_helper_check_plane_state() takes care of checking the scaling capabilities and calculating the clipped X/Y offsets for us. Rely on this function instead of open-coding the logic. Incidentally, it seems to fix a problem we had with negative X/Y positioning of YUV planes.

The offset adjustment depends on the framebuffer modified, so let's just move this operation in the DRM_FORMAT_MOD_LINEAR case inside vc4_plane_mode_set(). This we'll be able to fix offset calculation for DRM_FORMAT_MOD_BROADCOM_VC4_T_TILED and DRM_FORMAT_MOD_BROADCOM_SANDXXX.

X/Y positioning of T-format buffers is quite tricky and the current implementation was failing to position a plane using this format correctly when the CRTC X, Y or both X and Y offsets were negative. It was also failing when the SRC X/Y offsets were != 0.

vc4_plane_atomic_async_update() calls vc4_plane_atomic_check() which in turn calls vc4_plane_setup_clipping_and_scaling(), and since commit 58a6a36 ("drm/vc4: Use drm_atomic_helper_check_plane_state() to simplify the logic"), this function accesses plane_state->state which will be NULL when called from the async update path because we're passing the current plane state, and plane_state->state has been assigned to NULL in drm_atomic_helper_swap_state(). Pass the new state instead of the current one (the new state has ->state set to a non-NULL value).
