[Intel-gfx] [PATCH v2 00/18] drm/i915: VLV/CHV two-stage watermarks (v2)

[ville.syrjala at linux.intel.com]

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

A rebased version of the two stage watermark support for VLV/CHV. Mostly
just cosmetic changes due to churn. I did clear out that unused
intel_plane_wm_parameters structure Maarten pointed out.

The sticking point in the last series was the active_planes bitmask, but
I've decided to leave that as is because it was the most convenient way
to do it for VLV/CHV, and I think it should work quite well for g4x as
well (which is something I want to tackle after landing this stuff).
I might still change my mind when I get down to gen2-gen4 territory
but until I really start on that I don't want to needlessly change
directions.

Oh one new thing I added here is cleaned up versions of some the
tracepoints I used in debugging this stuff. I think those would
be usedful to have upstream so I've included them in the series.

Entire series is available here:
