This issue is affecting a hardware component which is not being actively worked
on anymore.

Moving the assignee to the dri-devel list as contact, to give this issue a
better coverage.

write NOPID reg after MI_WAIT for overlay

If you're still around, I've just stumbled over this little hint in the docs.
Maybe it actually helps. Test feedback highly appreciated.

Thanks, Daniel

Hi Daniel,
I believe I'm also bitten by this bug and I'd like to test your patch.
Unfortunately, MI_WRITE_NOPID_REG is not defined in the newest kernels
and I couldn't find any reference. If you could update your patch with
its definition, I can give it a go.

Cheers,
Stefan.

Just add
#define MI_WRITE_NOPID_REG (1 << 22)
somewhere.

Hi Daniel,

sorry for answering so late. I had a few hangs with 3.3.0 with this patch
until I realised that I had relaxed fencing enabled (which I enabled out
of curiosity at some point). Since then I went back to a plain config and
had a GPU hang with the vanilla 3.3.3, I can attach the error state output
if you think it can still be useful.

The good news is that 3.3.0 with this patch seems stable, and I am still
testing 3.3.3 with this patch and will report back if I manage to hang the
GPU (or not).

Cheers,
Stefan.

Please also check whether 3.3.0 without the patch still crashes,
otherwise we don't really know whether it's the patch that fixes
things.

Hi Daniel,
unfortunately, the patch doesn't seem to help.
I tested 3.3.3, 3.3.4, and 3.3.5 patched and unpatched.
Although, unlike in the OP, it takes a while for the gpu
to hang, sometimes hours. But I had hangs for both versions.

I captured some i915_error_states for the hangs, if you are
interested.

Cheers,
Stefan.

Always useful to check to see if there is any variation in the error states.
Can you also try:

I added some more error state files in the hope they will be useful.
"Patched" means with the patch from comment #13.
I'm still testing your patch.

Cheers,
Stefan.

As I was writing this, the mplayer window turned blue. :/

So it seems no luck with your patch, too, at least everything
besides xvideo still works and I can gracefully reboot.
I will attach the error state file, hope it helps.

Hth,
Stefan.

Hi,
are there any news on this issue?
The 3.4 and 3.5-rc series seem stable wrt this issue,
but unfortunately something broke resume from s2ram badly,
the backlight stays off and the machine does not respond
even to SysRq and I need to do a hard power-off.

Cheers,
Stefan.

That's good&bad news. Can you try to bisect the backlight regression that has
been introduce in 3.4 and open a new bug report? That usually helps in fixing
it ...

It turns out to be an ACPICA regression not related to graphics at all.

As for this issue, I did not observe any more hangs with v3.4 or 3.5-rc, *yet*.
It is hard to tell for sure since it usually takes a while (sometimes hours)
for it to occure. Which makes it also almost impossible to bisect and to find
the commit that might have fixed it.

Cheers,
Stefan.
