            Bug ID: 107266
           Summary: Radeon Pro Duo (Polaris) - ring sdma0 timeout
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu-pro
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: rhlug@hotmail.com

Running a polaris Pro Duo on Ubuntu 18.04, Kernel from ROCm branch
4.17.0-rc2-180424-fkxamd and everything works great.

In testing latest drm-next-4.19-wip kernel, I get the following errors on boot,
and have no working opencl (ie clinfo hangs indefinitely)


[   58.913281] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout,
signaled seq=573, emitted seq=574
[   58.913284] [drm] GPU recovery disabled.
[   58.914276] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma1 timeout,

Please let me know if you need any specifics.

Please attach your full dmesg output.  Are you attempting to use ROCm over the
drm-next-4.19-wip kernel?

No, I wasnt running ROCm userland.

I've been using amdgpu-pro-18.20-606296 for several weeks with the fkxamd
kernel as recommened by Felix.

When I remove all userland, I dont see the ring sdma0 timeout.  Without any
userland,  it initializes the driver, but with a couple warnings.

So I stripped this down, and the ring error pops up after I've applied a new
pp_table and start utilizing the GPU. 

My guess is this error has something to do with why this doesnt work in
drm-next-4.19-wip

[    2.635258] amdgpu: [powerplay] Failed to retrieve minimum clocks.
[    2.635259] amdgpu: [powerplay] Error in phm_get_clock_info 

That error is not present when I load 4.17.0-rc2-180424-fkxamd kernel.

I apply same pp_table file while running 4.17.0-rc2-180424-fkxamd, and it works
as expected.

So there is something funky in the powerplay of drm-next-4.19-wip

Both of these kernels work fine on my Vega 56 and Vega 64's, just the Pro Duo
has the ring timeouts.   Was tested with amdgpu-pro 18.20 and 18.30, and
nothing utilizing the GPUs besides on boot initializations.

All Polaris are experiencing ring errors on mainline kernels, its not just Pro
Duo Polaris.
