[Mesa-dev] [PATCH 04/16] i965/skl: Set mask bits in PIPELINE_SELECT on Skylake.

[Kristian Høgsberg]

From: Kenneth Graunke <kenneth at whitecape.org>

Skylake has some extra bits in PIPELINE_SELECT, none of which are
interesting for a 3D driver.  In order to selectively change them, it
also introduces new "mask bits" in 15:8.  We care about the "Pipeline
Selection" bits (1:0), so set the mask to 0x3.
