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.
