Patches 1-4 are
Reviewed-by: Ian Romanick <ian.d.roman...@intel.com>
Since these patches have been through the wringer, you should go ahead
and land these four... even if the other 5 still have to wait.

The set introduces new target for 'eglCreateImageKHR()' allowing one
to create EGL images out of externally allocated buffers. For now
only natively supported RGB formatted buffers are accepted.
This revision ties the dma-buffer import extension tightly with the
image external extension. One can access the dma-buffers only for
reading and via the image external sampler. Image external extension
itseff is not previously supported and here it is enabled solely for
imported dma-buffers and for nothing else.
I left the generic plumbing for YUV specific attributes in place as
people spent quite a bit of time reviewing it and it is likely to be
useful later on.
v2:
- added support for treating buffers having packed format
separately from the planar (that require special care)
intel: allow packed prime buffers to be treated normally
- tried to address all Eric's comments:
intel: refactor planar format lookup
intel: prepare for dri images having more than plane
- added missing check for explicit "no context"
egl: definitions for EXT_image_dma_buf_import
v3-4:
- close the file descriptors as the ownership is transferred
to EGL
- declare the extension as EGL (not GLES)
- import EGL definitions from khronos
- no not break DRI image ABI, but introduce new entry and update
the version of the interface
v5-6:
- clarified the use of regions-array (Chad)
- omit duplication of image with no regions (Chad)
- distinguish invalid drm format from unsupported (Chad)
- fix the rejection of all hints (Chad)
- report invalid context as EGL_BAD_PARAMETER instead of as
EGL_BAD_CONTEXT (Eric)
v7:
- native RGB formats only and only via image external sampler
v8:
- fixed return EGL errors codes, documentation and plane
attribute checking
Topi Pohjolainen (9):
intel: allow packed prime buffers to be treated normally
intel: do not create renderbuffers out of planar images
intel: refactor planar format lookup
intel: set dri image dimensions even when creating out of primes
dri: propagate extra dma_buf import attributes to the drivers
egl: definitions for EXT_image_dma_buf_import
intel: restrict dma-buf-import images to external sampling only
egl/dri2: support for creating images out of dma buffers
i965: enable image external sampling for imported dma-buffers
