Ben Widawsky 0cc2764cc4 drm/i915: use cpu_relax() in wait_for_atomic ... As part of the advice given to us from the hardware designers regarding the maximum wait time on the forcewake handshake we need to move from us granularity to ms granularity. In earlier patches to do this, Jani noticed that wait_for_us was properly converted to use cpu_relax(), but wait_for was not. The issue has existed since the introduction of the macro: commit 913d8d1100 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Aug 7 11:01:35 2010 +0100 drm/i915: Ensure that while(INREG()) are bounded (v2) CC: Jani Nikula <jani.nikula@linux.intel.com> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Chris Wilson <chris@chris-wilson.oc.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2012-09-03 10:21:29 +02:00
