          Priority: medium
            Bug ID: 62997
          Assignee: dri-devel@lists.freedesktop.org
           Summary: GPU fault unless R600_DEBUG=nodma
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: udovdh@xs4all.nl
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

Ever since booting into kernel.org 3.8.4 on my AMD A10-5800K (ARUBA graphics),
running git mesa and git xf86-video-ati, I get short uptimes (15 minutes,
around one hour max) due to crashes.
The logs mention stuff like:

[ 1332.480233] radeon 0000:00:01.0: GPU fault detected: 146 0x0134710c
[ 1332.480243] radeon 0000:00:01.0:   VM_CONTEXT1_PROTECTION_FAULT_ADDR  
0x00000813
[ 1332.480250] radeon 0000:00:01.0:   VM_CONTEXT1_PROTECTION_FAULT_STATUS
0x0407100C

Watching youtube `helps` triggering the issue as it appears. (correlates, no
real causation yet) 
Having R600_DEBUG=nodma in the environment solves the problem.

Occasionally I see a GPU lockup, if that is related:

With R600_DEBUG=nodma we get some mentions of GPU fault but not as often and no
crashing the whole PC.

It does crash, but without reboot.
Gui disappears.
Pure text mode screne is shown of first few seconds of boot.
No network. Kernel alive.

This may be related to bug 62959.  Does attachment 72794 (kernel patch) fix the
issue?

3.8.6 with and without patch had crashes of various kind. (hard freeze even!)
Now doing 3.8.5 without patch, waiting for the raid check to complete.

Despite crashes for other reasons (ARUBA (Cayman) not yet ready for OpenCL) I
saw no GPU faults etc in the logs since booting into 3.8.5 with the patch.
I want to give it a few more days without OpenCL disruptions to be sure.

This is starting to look like a duplicate of bug 62959.  Can you try attachment
77608?  That seems to fix 62959, hopefully it will fix this one as well.

So I undo the previous patch and try this new one?
(Or try them combined?)

Try them separately, not combined.

I guess the second patch also fixes the issue.
After  1 day, 15:11 of uptime I saw no GPU faults, hangs, etc.
Normally they occurred much sooner than that.
