[Mesa-dev] [PATCH 3/5] i965: Fix INTEL_DEBUG=shader_time for Haswell.

[Eric Anholt]

From: Kenneth Graunke <kenneth at whitecape.org>

Haswell's "Data Cache" data port is a single unit, but split into two
SFIDs to allow for more message types without adding more bits in the
message descriptor.

Untyped Atomic Operations are now message 0010 in the second data cache
data port, rather than 6 in the first.

v2: Use the #defines from the previous commit. (by anholt)

NOTE: This is a candidate for the 9.1 branch.
