Priority: medium
Bug ID: 58354
Assignee: dri-devel@lists.freedesktop.org
Summary: r600g locks up in Unigine Tropics with drm-next
Severity: critical
Classification: Unclassified
OS: All
Reporter: alexandre.f.demers@gmail.com
Hardware: Other
Status: NEW
Version: git
Component: Drivers/Gallium/r600
Product: Mesa
Testing with drm-next with latest mesa, ddx and drm, Unigine Tropics locks up
when launching the demo. The problem appears somewhere between
a636a9829175987e74ddd28a2e87ed17ff7adfdc (locks) and
1a1494def7eacbd25db05185aa2e81ef90892460 (OK). I'll pinpoint it tomorrow.

drm/radeon: use DMA engine for VM page table updates on cayman/TN
DMA engine has special packets to facilitate this and it also keeps
the 3D engine free for other things.

Hitting some other bug right now with bug 58655. I'll apply the proposed patch

dmesg after lockup
This is the salvaged dmesg retrieved with the help of a ssh connection. Sadly,
I don't think there is anything useful in there.

Doesn't fix it, it locks as before. Sadly, dmesg seems to loose the count
because of another bug introduced in 3.8-rc1. Now that I moved to 3.8-rc1,
there is a huge amount of messages appearing in errors.log and dmesg (when
typed in the terminal):

I'm sure it is a different bug, can you confirm? dmesg.log stops to be
populated when X/Gnome start, but typing dmesg in a terminal outputs tons of
the reported messages. Should I open a new bug for it or has it been already
reported?

I know there is a CS error, I see a message in the terminal just when the lock
happens. This is where I should check in dmesg. This is the only thing I can
confirm for now because of bug 58667 which floods my logs.

Is there anything in the kernel log when this happens now that the mesa fix is
applied? Also does the patch in attachment 72013 help now that the mesa side
is fixed?

With or without the patch, it still ends saying the kernel rejected the CS and
to check in dmesg. Then, it freezes. However, accessed through ssh, there is
nothing I could get from it.
I killed Xorg remotely, the screen blinked for a moment and only garbage was
displayed. I was able to retrieve something from dmesg. I killed it a second
time to only get some different garbage.
I'll attach the file right away.

Does a 3.8 kernel it work ok if you revert mesa back to
cf5632094ba0c19d570ea47025cf6da75ef8457a?
I think
r600g: rework flusing and synchronization pattern v7
http://cgit.freedesktop.org/mesa/mesa/commit/?id=24b1206ab2dcd506aaac3ef656aebc8bc20cd27a
may be problematic on cayman.

If it is, not for this bug. Went back to cf563, applied a fix for glcpp,
reloaded libraries and still locks at the same point, even after rebooting.

No. I was able to catch something in errors.log and kernel.log though. I'm
attaching the truncated file in a few seconds. I hit a GPU fault.
I'll do the same test without the patch to know if it is related or not.

errors.log when tropics froze with patch 72794
It was originally about 53MB since it kept pumping messages until I hit the
reset button. But it was all the same things over and over, so I truncated it.
Same messages were recorded in everything.log and kernel.log without any
previous error messages.

Just to let you know, it does the same thing either I apply the patch or not,
even with today's latest kernel git. I just have to prepare to launch Tropics,
connect through ssh from my tablet, launch Tropics and when it freezes, call
dmesg from the tablet. Then, I'll have the GPU faults logged in my different
log files.

patch 1/2
Does this set of patches fix the issue? I think we are running out of ring
space for large VM page table updates since the DMA ring is smaller than the CP
ring.

It fixes the thing! Good work! I've let it run for some time and it ran without
any locks.
