6900XT and OpenCL on Linux

Hello. I'm trying to get OpenCL working on Linux Ubuntu 20.04.1 LTS on my 6900XT. I've tried these combinations:

1)

ubuntu kernel 5.4.0-54

amdgpu driver 20.45-1188099 with included rocr dkms

result: GPU is detected but clinfo hangs part way through displaying the info. My opencl code hangs trying to create a context

 

2)

ubuntu kernel 5.4.0-54

amdgpu driver 20.45-1188099 with --no-dkms and rocm 4.0.0.40000-23 (rocm-opencl 3.6Beta-17-g875c1f8-rocm-rel-4.0-23)

result: GPU is not detected. clinfo shows the platform AMD Accelerated Parallel Processing but has 0 devices

3)

upstream kernel 5.10.0-051000

rocm 4.0.0.40000-23 (rocm-opencl 3.6Beta-17-g875c1f8-rocm-rel-4.0-23)

result: rocminfo sees the GPU fine, clinfo hangs after displaying some of the data for the GPU just like in 1)

Here's the GPU data for rocminfo:

<clinfo hangs here>

Has anyone gotten OpenCL working? Am I doing something wrong? I got this card specifically for a compute research project I'm doing so any help I can get on this is appreciated. I'm happy to provide any other info I can. Thanks!

Re: 6900XT and OpenCL on Linux

A couple of edits to my above post. My pyopencl code doesn't hang creating the context, it hangs after that when creating the command queue.

 

Also, I'm running the GPU with an FX-8350. From reading the rocm documentation older GPUs require PCIe 3.0 atomics which this CPU doesn't support but I also am guessing the 6900XT is new enough to not require it.

 

I'm open to other OS/software combinations to get this working so if anyone has this working under a different configuration I'd be happy to try it too! I've seen opencl benchmarks for this card so it has to work somehow right?

 

Thanks again

Re: 6900XT and OpenCL on Linux

Having the same issue with a 6800xt + VII

 

Clinfo + rocminfo hangs

Foldiong@home fails use either too.

 

Did you ever find the issue . Seems like the 6000 series is not yet supported maybe.

 

I'm using Manjaro (Arch based)

5950x

Kernel 5.11

ROCM 4.0.0.1

Re: 6900XT and OpenCL on Linux

Unfortunately I never solved this. I confirmed that the same problem exists on CentOS. I've been running my code on Windows which isn't efficient for my workflow and also periodically produces bizarre results so I've been waiting for AMD to release an update for the Linux driver. It has been 2 months so hopefully it will happen soon.

Re: 6900XT and OpenCL on Linux

Update: I downloaded the new 20.50 linux drivers and installed them in a fresh install of Ubuntu and it still hangs on clinfo. I was hoping that this basic functionality would work after 3 months but no luck yet 😞

Re: 6900XT and OpenCL on Linux

Good news, The update to rocm-opencl/HSA-rocr 4.1 today seems to have fixed it for me .

Working well now

 

If memory serves the 6xxx series requires rocm to use openCL so might be an idea to try that Terrence !

Unbutu should have the update I would have thought.

Re: 6900XT and OpenCL on Linux

Thanks for the info! I tried installing rocm-dkms from the ROCm repo but then my card wasn't detected at all. I also tried installing rocm-opencl4.1.0 and hsa-rocr-dev4.1.0 among others but that didn't help either. Did I miss a step?

Re: 6900XT and OpenCL on Linux

Have you tried reporting it to ROCm on GitHub?

Re: 6900XT and OpenCL on Linux

You need to remove the previous version as upgrading causes issues. Best off purging all related romc/hsa packages and then trying.

I don't have have hsa-rocr-dev installed so but have the following on mine

 

hsa-rocr 4.1.0-1
hsakmt-roct 4.1.0-1

rocclr 4.1.0-1
rock-dkms-bin 4.0.1-1
rock-dkms-firmware-bin 4.0.1-2
rocm-cmake 4.1.0-1
rocm-device-libs 4.1.0-1
rocm-opencl-runtime 4.1.0-1
rocminfo 4.1.0-1
