[Intel-gfx] [PATCH] drm/i915: Enable FBC on GEN7 by default

[Ben Widawsky]

I am not clear why we've never enabled it by default for GEN7. Looking
at the git hostiry, it seems Rodrigo disabled it by default, and it's
never been turned on. Quite a few fixes have gone in over the past year,
and I think many of us are running this successfully.

If there is some reason we know of why we don't enable this by default
on GEN7, then please ignore the patch, and forgive my laziness.
