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

[Jordan Justen]

1. No longer allocate a miptree structure for hiz on gen7+.

2. Always enable hiz for depth on gen8+.

3. Enable hiz Auxiliary Buffer support on gen8. This support allows
   Broadwell to sample from depth using the hiz buffer, and thereby
   removing the need to resolve depth to/from the hiz buffer in many
   cases.

v2:
 * Modified hz_height calculation in patches 4 & 5

Patches without Reviewed-by: 4, 5, 6, 13 and 14

This series is available in the bdw-aux-hiz-v2 branch of:
git://people.freedesktop.org/~jljusten/mesa
