drm/omap: fix tiled buffer stride calculations

2017-06-02T08:09:34+00:00

omap_gem uses page alignment for buffer stride. The related calculations are a bit off, though, as byte stride of 4096 gets aligned to 8192, instead of 4096. This patch changes the code to use DIV_ROUND_UP(), which fixes those calculations and makes them more readable. Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart

drm/omap: fix YUV422 90/270 rotation with mirroring

2017-06-02T08:09:33+00:00

When rotating 90/270 + mirroring with YUV422, the end result will have adjacent pixels swapped. The problem is that dispc_ovl_set_rotation_attrs() has wrong rotation values for these cases. Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart

drm/omap: fix YUV422 rotation with TILER

2017-06-02T08:08:59+00:00

TILER rotation with YUV422 pixelformats does not work at the moment. All other pixel formats work, because the pixelformat's pixel size is equal to tiler unit size (e.g. XR24's pixel size is 32 bits, and the TILER unit size that has to be used is 32 bits). For YUV422 formats this is not the case, as the TILER unit size has to be 32 bits, but the pixel size is 16 bits. The end result is OCP errors and sync losts. This patch adds the code to adjust the variables for YUV422 formats. We could make the code more generic by passing around the pixel format, rotation type, angle and the tiler unit size, which would allow us to do calculations without special case for YUV422. However, this would make the code more complex, and at least for now this is much more easier to handle with these two special cases for YUV422.

drm/omap: pass rotation to dispc

2017-06-02T08:08:15+00:00

The omapdrm driver has not passed the rotation value to the dispc driver. This doesn't affect RGB formats, but YUV formats don't work without dispc knowing the orientation. Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart

drm/omap: DRM_MODE_REFLECT_* instead of mirror boolean

Change dispc driver to use the DRM_MODE_REFLECT flags instead of a mirror boolean. Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart

drm/omap: use DRM_MODE_ROTATE_* instead of OMAP_DSS_ROT_*

2017-06-02T08:05:32+00:00

At the moment the dispc driver uses a custom enum for rotation. Change it to use the DRM's DRM_MODE_ROTATE_*. Note that mirroring is at the moment handled as a separate boolean in the dispc driver, so we only use the DRM_MODE_ROTATE_* values. Note, DSS HW uses clockwise rotation, DRM counter-clockwise.

drm/omap: remove omap_drm_win

2017-06-02T08:04:17+00:00

struct omap_drm_window is only used to pass plane setup data to omap_framebuffer_update_scanout(). This can as well be accomplished by just passing the DRM state. Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart

drm/omap: add drm_rotation_to_tiler helper()

2017-06-02T08:04:07+00:00

Add a helper function to convert DRM rotation to TILER rotation. Also drop a error print that can never happen, as the DRM framework makes sure the rotation is valid. Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart

drm/omap: cleanup formats array

2017-06-02T07:57:25+00:00

omap_fb.c has a table with DSS and DRM formats, used to convert between them. This is no longer needed, so we can change the array to a plain array of DRM_FORMAT_* values which contain all possible pixel formats supported by any DSS IP version.
