[Intel-gfx] [PATCH v2 0/6] drm/i915: SAGV fixes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

While pokingaround the watermarks/etc. I noticed our SAGV code
has a bunch of bugs. Let's try to fix it.

Pushed a few patches from v1 already. And based on the discussion
with Stan I added a few extra refactoring patches to the end in the
hopes of making the logic less confusing. I still prefer the oneliner
for the immediate bugfix in patch 2 so that we don't have to backport
the refactoring as well.
