[PATCH 0/3] GET_PLANE2 w/ i915 implementation

[Ben Widawsky]

This patch series implements GET_PLANE2 support for Intel platforms and defines
the new kernel UAPI. The idea was originally introduced by Kristian. Ultimately,
the purpose of the new API is to provide the ability to query per-plane
modifiers in KMS. These modifiers, which are just fb modifiers, will be used by
the client to enable optimal modifications for framebuffers. A reference
implementation in kmscube is referenced (in that code is a comment for an
optimal algorithm not implemented).

This work has been discussed on the mailing list and IRC over the last few weeks
and this is a result of the agreed changes. There is still some debate about the
UAPI, I believe, but I can firmly say that this seems entirely sufficient for
Intel platforms in the foreseeable future.
