            Bug ID: 92087
           Summary: [Radeon/Tonga] lockup in valley demo
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: edward.ocallaghan@koparo.com

Hi,

Upon running the valley demo I experience I lockup after a while. I can recover
by switching to another virtual term and killing X.

dmesg shows this repeatedly with only a difference of the value after the fault
id? of 146 after the lockup:

--------------------

VM fault (0x00, vmid 0) at page 0, read from '' (0x00000000) (0)
amdgpu 0000:01:00.0: GPU fault detected: 146 0x02704004
amdgpu 0000:01:00.0:   VM_CONTEXT1_PROTECTION_FAULT_ADDR   0x00000000
amdgpu 0000:01:00.0:   VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x00000000

--------------------

This is with mesa 11.0.1 (8ae8feca) + kern 4.3.0-rc2 + libdrm 2.4.65

No idea how to get a card state dump with amdgpu?

Edward.

--- Comment #1 from Andy Furniss <adf.lists@gmail.com> ---
There are a couple of related bugs already open.

The VM fault seems to have appeared with more recent kernels, I can get those
now even without locking.

If you leave valley for a couple of minutes after lock you will likely get a
hung task trace like those in the bugs below (Though not a GPU reset as that is
not enabled on more recent kernels)

It would probably be best to mark this bug a DUP of one of these.
