[Mesa-dev] [PATCH v13 00/36] EGL dmabuf modifiers import & i915 CCS

[Daniel Stone]

Hi,
This series is an amalgamation of two series: Varad's
EGL_EXT_image_dma_buf_import_modifiers support (last seen at v3), and
Ben's i915 CCS support (last seen at v12). I've fairly heavily rebased
them, fixed up the Intel paths, and Varad had also fixed up the
Gallium/pipe parts from Lucas's review.

This is enough for me to get Weston on GBM running with CCS (verified
that it was spitting out two planes with the appropriate modifier, and
also that forcing to single-plane Y-tiled gave me something that looked
a lot like a compressed buffer), and also to get CCS dmabuf imports
working (tested by hand).

Ben's /* FINISHME */ about using ISL for format/modifier handling
definitely still applies, but after looking at it for a little while,
seemed like a far bigger adventure to plumb everything through ISL.
But I'd be happy to do what I can, or at least review, that later.

Cheers,
Daniel
