Originally based off of a patch by Kristian.
This new ioctl extends DRM_IOCTL_MODE_GETPLANE, by returning information about the modifiers that will work with each format.
It's modified from Kristian's patch in that the modifiers and formats are setup by the driver, and then a callback is used to create the format list. The LOC was enough difference that I don't think it made sense to leave his authorship, but the new UABI was primarily his idea.
Additionally, I hit a couple of drivers which Kristian missed updating.
It also contains a change requested by Daniel to make the modifiers array a sentinel based structure instead of a sized one. Upon discussion on IRC, it was determined that having an invalid modifier might make sense in general as well.
v2: - Make formats uint32_t, and use an offset, see the comment in the patch. Add a WARN_ON and early bail for when there are more than 32 formats. (Rob) - Remove DRM_DEBUG_KMS (Ville) - make flags come before count in struct (Ville)
v3: - Make formats 64b again to defer the pain, and add a pad - Make init fail if > 64 instead of at get_plane. This could be made more optimal by doing it in get_plane because 0 masked modifiers don't need to be reported back to userspace. As a result, the first driver to go back 64 formats has to deal with this. - Fix the comment to be more clear.
v4: - Add drivers/gpu/drm/qxl/
