[Mesa-dev] [PATCH v2 00/14] i965/gen7+ hiz cleanup + gen8 hiz improvements

[Jordan Justen]

Ken,

I think you were concerned about:
[PATCH v2 06/14] i965/gen8: Enable hiz for all depth levels
but, you weren't able to reproduce any issues with it.

Should we try this series on master now that 10.3 has branched?
