* drm: Plumb modifiers through plane initBen Widawsky2017-08-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the plumbing for supporting fb modifiers on planes. Modifiers have already been introduced to some extent, but this series will extend this to allow querying modifiers per plane. Based on this, the client to enable optimal modifications for framebuffers. This patch simply allows the DRM drivers to initialize their list of supported modifiers upon initializing the plane. v2: A minor addition from Daniel v3: * Updated commit message * s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu) * Remove some excess newlines (Liviu) * Update comment for > 64 modifiers (Liviu) v4: Minor comment adjustments (Liviu) v5: Some new platforms added due to rebase v6: Add some missed plane inits (or maybe they're new - who knows at this point) (Daniel) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Daniel Stone <daniels@collabora.com> (v2) Reviewed-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Daniel Stone <daniels@collabora.com>
* drm: Clarify the role of plane_state argument to drm_simple update().Eric Anholt2017-03-301-1/+1
| | | | | | | | | | | Like the atomic update hook it's wrapping, the plane_state is the old one, and the new one is in plane->state. Both msxfb and tinydrm use it correctly, but I mistook it for the new state in pl111 due to its naming.

* drm/kms-helpers: Use recommened kerneldoc for struct member refsDaniel Vetter2017-01-251-6/+6
| | | | | | | | | | | | | | | | | | I just learned that &struct_name.member_name works and looks pretty even. It doesn't (yet) link to the member directly though, which would be really good for big structures or vfunc tables (where the per-member kerneldoc tends to be long). Also some minor drive-by polish where it makes sense, I read a lot of docs ... v2: Comments from Gustavo.

* drm/doc: use preferred struct reference in kernel-docDaniel Vetter2016-12-301-4/+4
| | | | | | | | | | | | | | | sed -e 's/\( \* .*\)struct &\([_a-z]*\)/\1\&struct \2/' -i Originally I wasnt a friend of this style because I thought a line-break between the "&struct" and "foo" part would break it. But a quick test shows that " * &struct \n * foo\n" works pefectly well with current kernel-doc. So time to mass-apply these changes!

* drm/simple-helpers: Always add planes to the state updateDaniel Vetter2016-08-251-0/+6
| | | | | | | | | | | | | | | | | Our update function is hooked to the single plane, which might not get called for crtc-only updates. Which is surprising, so fix this by always adding the plane. While at it document how&when the event should be sent out better in the kerneldoc.
