Hi Chris, I bisected the suspend regression I mentioned, and came to this commit:
commit 0cdab21f9a1fca50dd27e488839f5a6578e333b2 Author: Chris Wilson <[email protected]> Date: Sun Dec 5 17:27:06 2010 +0000 drm/i915: Uncouple render/power ctx before suspending Signed-off-by: Chris Wilson <[email protected]> Disabling power context tear down on suspend with this diff: diff --git a/drivers/gpu/drm/i915/i915_suspend.c b/drivers/gpu/drm/i915/i915_suspend.c index a311809..6e98764 100644 --- a/drivers/gpu/drm/i915/i915_suspend.c +++ b/drivers/gpu/drm/i915/i915_suspend.c @@ -820,7 +820,7 @@ int i915_save_state(struct drm_device *dev) if (HAS_PCH_SPLIT(dev)) ironlake_disable_drps(dev); - intel_disable_clock_gating(dev); +// intel_disable_clock_gating(dev); /* Cache mode state */ dev_priv->saveCACHE_MODE_0 = I915_READ(CACHE_MODE_0); NB: I've not tested later than c57802706aad9f179f2219415717896b3c177845, which does not suspend. (I'm actually pretty certain that I tested until around a8e93126a6f10d0a14ba8407ec112b1b3a5e2e97, but it was still bad, and I didn't need to include it in my bisect, I did not make any notes about it.
