From f05dd2f09cac422c423dae8f9b8e2be13df05a8f Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 26 Feb 2010 13:32:11 -0800 Subject: drm/i915: Don't bother with the BKL for GEM ioctls. We probably don't need it for most of the other driver ioctls as well, but we explicitly did locking when doing the GEM pieces. On CPU-bound graphics tasks, the BKL was showing up as 1-2% of CPU time.

Which happens on untiled->tiled transition quite often on 4th gen and later because there fencing does not have any special alignment constraints (as opposed to 2nd and 3rd gen on which I've tested the original commit).

I've been getting more and more quirk reports about this. It seems clear at this point that other OSes are not using this for determining whether the integrated panel should be turned on, and it is not reliable for doing so. Better to light up an unintended panel than to not light up the only usable output on the system.
