[Intel-gfx] [PATCH v4 0/4] Blobifiers (FKA GET_PLANE2)

[Ben Widawsky]

These patches create the blob property for modifiers, and the implementation for
i915 modifiers. This [generally] has been tested in Weston by Daniel Stone as
well as an earlier version of kmscube. This patch series was formerly known as
"GET_PLANE2" because the interface for obtaining the modifiers was extended
throug GET_PLANE instead of a blob property.

The modifier blob (blobifier) presents a list of modifiers per plane, and a
related bitmask [1] back to userspace, via KMS, so that a client such as a
compositor may utilize those modifiers for buffer creation via GBM, or buffer
import via dmabuf/EGL.

All vendors may optimize via their supported modifiers. For Intel, this is one
of the pieces required to support end to end lossless compression (a memory
bandwidth saving technique semi-common across GPUs).

I do apologize if I missed some previous review comments. A ton of things came
up and it took a while to spin this rev. Nothing was missing intentionally.

[1] The bitmask is used to show the connection between which modifiers are
supported by which formats.

  drm: Plumb modifiers through plane init
  drm: Create a format/modifier blob
  drm/i915: Add format modifiers for Intel
  drm/i915: Add support for CCS modifiers
