[Intel-gfx] [PATCH] drm/i915: Clean up device info structure definitions

Wayne Boyer wayne.boyer at intel.com
Tue Dec 1 11:34:47 PST 2015


Beginning with gen7, newer devices repetitively redefine values
for the device info structure members.  This patch simplifies the
structure definitions by grouping member value definitions into the
existing GEN7_FEATURES #define and into the new GEN7_LP_FEATURES
and HSW_FEATURES #defines.

Specifically, GEN_DEFAULT_PIPEOFFSETS and IVB_CURSOR_OFFSETS are
added to GEN7_FEATURES and subsequent IVB definitions are simplified.

GEN7_LP_FEATURES is created to differentiate and simplify the
gen7 low power (LP) devices.

HSW_FEATURES is created and used to simplify all HSW+ devices
except for LP.
