[Mesa-dev] [PATCH v3 00/14] i965: Add support for I916_FORMAT_MOD_Y_TILED_CCS

[Jason Ekstrand]

This is yet another respin of the patch series to enable the CCS_E format
modifier.  Most of v2 has been pushed and this contains the bits that still
need review.  Fortunately, the series gets shorter each time I send it!

Most of the fixes are from review comments by Chad.  Six of the fourteen
patches are new.  However, all of the new patches are fairly straight-
forward and shouldn't take significant effort to review.  The series can be
found here:

Happy Reviewing!
