Commit Message

From: Chandra Konduru <[e-mail]>

This patch adds NV12 to list of supported formats for sprite plane.

v2: Rebased (me)

v3: Review comments by Ville addressed
- Removed skl_plane_formats_with_nv12 and added
NV12 case in existing skl_plane_formats
- Added the 10bpc RGB formats

v4: Addressed review comments from Clinton A Taylor
"Why are we adding 10 bit RGB formats with the NV12 series patches?
Trying to set XR30 or AB30 results in error returned even though
the modes are advertised for the planes"
- Removed 10bit RGB formats added previously with NV12 series

v5: Missed the Tested-by/Reviewed-by in the previous series
Adding the same to commit message in this version.
Addressed review comments from Clinton A Taylor
"Why are we adding 10 bit RGB formats with the NV12 series patches?
Trying to set XR30 or AB30 results in error returned even though
the modes are advertised for the planes"
- Previous version has 10bit RGB format removed from VLV formats
by mistake. Fixing that in this version.
Removed 10bit RGB formats added previously with NV12 series
for SKL.

v6: Addressed review comments by Ville
Restricting the NV12 to BXT and PIPE A and B

v7: Rebased (me)

v8: Rebased (me)
Restricting NV12 changes to BXT and KBL
Restricting NV12 changes for plane 0 (overlay)

v9: Rebased (me)

v10: Addressed review comments from Maarten.
Adding NV12 to skl_plane_formats itself.

v11: Addressed review comments from Shashank Sharma

v12: Addressed review comments from Shashank Sharma
Made the condition in intel_sprite_plane_create
simple and easy to read as suggested.

v13: Adding reviewed by tag from Shashank Sharma
Addressed review comments from Juha-Pekka Heikkila
"NV12 not to be supported by SKL"

v14: Addressed review comments from Ville
Added skl_planar_formats to include NV12
and a check skl_plane_has_planar in sprite create
Added NV12 format to skl_mod_supported. These were
review comments from Kristian Høgsberg <[e-mail]>

v15: Added reviewed by from Juha-Pekka Heikkila

v16: Rebased the series

v17: Added all tiling under mod supported for NV12

On patch 5 and 6: this is a tad overkill, just put it below DRM_FORMAT_VYUY and let it fall through. It's not different from the other formats. :)
Otherwise looks good, I'll wait until the changes from drm-misc-next are merged into drm-intel-next-queued then this series can be applied with the minor fixup.

Sure, thank you. I'll make the change. I did this to fix a review comment - which said all modifiers aren’t
Covered for NV12 - when we earlier had it under VYUV. Would that be still okay?

Seems only CCS isn't covered, so putting it there should be fine. :)

Sorry to ask - under VYUV only Yf_TILED returns true. Don’t we need to
add the other modifiers like MOD_LINEAR, MOD_X_TILED and MOD_Y_TILED?

This is a C switch, unless there is a break it will continue, so it works as intended. :)

For example format UYVY if modifier == Yf_TILED_CCS, it will ignore all 
the lines with case and default, and continue to the end of the switch 
statement, or until it hits a 'break' so the below:


	case DRM_FORMAT_UYVY:
	case DRM_FORMAT_VYUY:
		if (modifier == I915_FORMAT_MOD_Yf_TILED)
			return true;
		/* fall through */
	case DRM_FORMAT_C8:
		if (modifier == DRM_FORMAT_MOD_LINEAR ||
		    modifier == I915_FORMAT_MOD_X_TILED ||
		    modifier == I915_FORMAT_MOD_Y_TILED)
			return true;
		/* fall through */
	default:
		return false;
}

for UYVY ends up being the same as:

if (format == DRM_FORMAT_UYVY) {
	if (modifier == I915_FORMAT_MOD_Yf_TILED)
		return true;
	if (modifier == DRM_FORMAT_MOD_LINEAR ||
	    modifier == I915_FORMAT_MOD_X_TILED ||
	    modifier == I915_FORMAT_MOD_Y_TILED)
		return true;
	return false;
}
