Ubuntu 20.04 AMDGPU Pro drivers (RX580) and OpenCL (ethminer related) (PARTIALLY SOLVED)

Heyya.
(SOLVED IN TERMS OF RUNNING BINARY)

Note from several updates - this is more turning up to be a oddball connected to the build methods of ethminer - with the combination of oddball of the AMD GPU PRO and OpenCL implementation connected to it…

(Converting this to a trial-and-error-thread-please-assist-if-you-want-thread, in case someone else ends up with the same issues…)

Been trying this morning and over lunch to smack the AMD GPU PRO drivers with OpenCL onto my Ubuntu 20.04 machine (Yes… I need that or at least something that fires off OpenCL). Reason, running ethminer.

# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.2 LTS
Release:        20.04
Codename:       focal

Backstory would be that I want to play with mining. I’ve targeted ethermine since it was a breeze to get running with my Nvidia-cards and CUDA.

However, it’s not a walk in the park with the AMD portion.

Standard packages, even adding on some that’s already in the standard repo will error out (well, ethminer 0.18/0.19 will -

So, of course I did some google-foo, and ended up with the ‘latest’ AMD driver for my RX580. (20.45 at time of writing) - actual install-params was headless and pro…

However, compiling the dkms-component explodes… (usually, all explodes but dkms-components triggers it…)

$ uname -r
5.8.0-43-generic

After som mashing - I’ve managed to “partially” get it right, (it’s a looong time banging on it and ended up removing for no real reason most of the other stale kernels and reinstalling 5.8.0-43

apt-get install --reinstall linux-image-$(uname -r) linux-modules-$(uname -r) linux-modules-extra-$(uname -r) linux-headers-$(uname -r)

Now, it got a bit more happy - but, the first error is back (instead of just "can’t find a proper gpu to use…).

$ dkms status
amdgpu, 5.6.20.906316-1188099: added

There’s a long threat I found that goes back a while with the 5.4 Kernel of Ubuntu 20.04,

Last entry confused me quite a bit…

In short - does anyone sit on any kind of pointers? :wink:
I thought the fighting drivers-days were over, but … wrong I was…

(OpenCL … really… this much trouble?)

Odd part - clinfo does print out statements… Perhaps it’s just the software I am trying to run that has the real issues?

Starting to look very much like the build of the binary I am trying to run has some serious issues and has hard AMD OpenCL binary that creates the scenario - I am trying to put my head into building it myself and will either kill this thread if I can figure out that it is the cause, or just see if it’s a joint issue…

(ethminer project link;
Release ethminer 0.18.0 · ethereum-mining/ethminer · GitHub )

Issue created at;

Issue cleared, as far as compiling and running it goes.

As always - thank you Arch Linux users, your documentation is amazing.

https://wiki.archlinux.org/index.php/AMDGPU

This means that after cloning the ethminer repo, and not just downloading the “source” compressed files, compiling works. What I used what to kill off the AMD binary included (and turned off CUDA).

So far final words:

I see this still as a problem but not actively looked at. There’s major issues with AMDGPU Pro as we know. Resolving this lies in the hands of AMD.

Developers going the partially great and partially lazy-turtle route will make things really hard. Including other git repos and forcing an init on those repos before building is just for me awkward. The AMD binary includes (to be dug out as far as I am capable) is an issue for ethminer.

I hope you all can get some useful information from all this.

Thank you for reading :).

Thanks for sharing this. Sadly, after spending a stupid amount of time trying to get OpenCL working with a 6900XT, I’ve remained unsuccessful. clinfo still shows 0 devices. I ended up passing it through to my Windows 10 VM for mining, and even then, it required a registry tweak to get ethminer working. The only thing I don’t really care for about this setup is that I can’t have ethminer running in a tmux session for convenient remote monitoring.

edit By purging all existing “stuff” from amdgpu-pro and rocm, installing kernel 5.9.10, installing amdgpu-pro --opencl=rocr, then doing the rocm user-level install (which bypasses the ROCk kernel driver), I was able to get ethminer (and clinfo) to recognize the card, but it reports 0.00 h. Also having the same issue of clinfo hanging reported here.
