Commit 'https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b45305fce5bb1abec263fcff9d81ebecd6306ede' breaks suspend on 845g running 3.8.0-rc6 kernel(sna and uxa are affected, though most times uxa crashes before I get to suspend, have not tested modesetting driver). I doubt reverting this fixes the underlining cause though as I tried in on a newer kernel 'https://www.kernel.org/pub/linux/kernel/v3.x/testing/linux-3.10-rc1.tar.xz' and it did not work (It does work on the 3.8.0-rc6 kernel). It was mostly by hand on the latter, so there is a chance I misapplied it.

Comment 1 Daniel Vetter 2013-05-20 20:12:23 UTC
How exactly does your machine go down when failing at suspend/resume? Hard-hang, only unuseable gpu or something else?

To test whether disabling the mentioned patch fixes things you can change the

- if (flags & I915_DISPATCH_PINNED) {
+ if (1) {

condition in i830_dispatch_execbuffer.
Comment 2 clockley1 2013-05-21 02:14:42 UTC
It wakes up but the screen is blank and the caps lock key does not work, did not test over network.

Downloaded 'https://www.kernel.org/pub/linux/kernel/v3.x/testing/linux-3.10-rc6.tar.xz' and compiled with patch; this kernel does not even suspend. The screen stays on and displays screen corruption not unlike a hung gpu.

Workaround that works on my system

This patch requires the "if (1 || flags & I915_DISPATCH_PINNED) {" patch.

next patch

This patch requires the last patch.
Comment 7 clockley1 2013-06-18 13:00:21 UTC
I have not thoroughly tested the patches. They may have intended side effects and probably break other hardware.

Though I suspect we may need a SRC_COLOR command to clear the ring->private on every ring init.

Sorry about the delay, unfortunately this patch does not work, at least on this machine.

Created attachment 81948 [details] [review]
fix up ring cleanup

Can you please test the attached patch? Please test this on the first broken kernel, not the latest one in case we've accidentally broken something else in between.
Comment 12 Chris Wilson 2013-07-05 19:24:33 UTC
You need Daniel's ring cleanup patch, and I think (the second chunk) of:

Does that mean I get a tested-by from you Chris on my patch?
Comment 14 Chris Wilson 2013-07-11 10:38:00 UTC
In the maybe we need to clear the bounce buffer vein:

    drm/i915: Clear the workaround batch bo for gen2

Can you please test with my userptr branch at http://cgit.freedesktop.org/~ickle/linux-2.6 ?
Comment 15 Chris Wilson 2013-07-11 11:36:05 UTC
No need to test as that branch died upon resume here.
Comment 16 Balló György 2013-08-07 10:53:47 UTC
The resume from suspend is still broken on 845G with kernel version 3.10.5. I can't see anything, just a blank screen. The last working version is 3.7.10.
Comment 17 Chris Wilson 2013-09-23 17:28:10 UTC
Note to self, -nightly still broken. And there is a hang during suspend if using glxgears -fullscreen.
Comment 18 clockley1 2014-01-15 04:25:53 UTC
The latest kernel from "http://cgit.freedesktop.org/~danvet/drm-intel/?h=drm-intel-next" works for me.

Are you happy to close this as working now but cause unknown?

Sure, that's fine.
