Subject: [PATCH 1/9] drm/i915: SAGV is not SKL-only, so rename a few things
Date: Tue, 13 Sep 2016 21:38:14 -0300	[thread overview]
Message-ID: <1473813502-16844-2-git-send-email-paulo.r.zanoni@intel.com> (raw)
In-Reply-To: <1473813502-16844-1-git-send-email-paulo.r.zanoni@intel.com>

The plan is to introduce intel_has_sagv() and then use it to discover
which platforms actually support it.

I thought about keeping the functions with their current skl names,
but found two problems: (i) skl_has_sagv() would become a very
confusing name, and (ii) intel_atomic_commit_tail() doesn't seem to be
calling any functions whose name start with a platform name, so the
"intel_" naming scheme seems make more sense than the "firstplatorm_"
naming scheme here.
