[Intel-gfx] [PATCH 00/16] drm/i915: 830M/ns201 fixes again

[ville.syrjala at linux.intel.com]

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

Thomas asked me to repost my 830/ns2501 patches. So here they are. I added
a few more patches (trickle feed and unused ring init) to fix some post-resume
issues. The primary plane rmw elimination patches and some locking/load detect
fixes already got merged.

Apart from these we still lack the minimum watermark check. I guess
we could just take the patch Thomas posted [1]. Doesn't look like a
more advanced solution is coming any time soon. Though the commit
message of that patch needs work and it lacks a s-o-b.

The VGACNTR patch might not be necessary any longer since Daniel's
vga/dummycon stuff. I don't recall if I tested without it, but my
gut feeling is that it's no longer needed. But I included the patch
here anyway.
