Re: Can't get OpenCL to work on OS stack with vega 56

Switching to mesa I'm getting 0 Platforms again. Should I try switching to LH?

Re: Can't get OpenCL to work on OS stack with vega 56

Yes, if that also fails I think it's time to try a mesa-git build without opencl/clover support.

Re: Can't get OpenCL to work on OS stack with vega 56

Mind walking me through the process again? Add LH's package source, and then just pacman -Syu ?

Re: Can't get OpenCL to work on OS stack with vega 56

Add LH"s repo and enable [testing] & [multilib-testing] repos.
Then run pacman -Syu .

Edit:

Once that's finished run the saem pacman command you used to revert from my mesa-git to offical mesa , but with adding -git to the packagenames.

Re: Can't get OpenCL to work on OS stack with vega 56

Had 0 Platforms at first, and then realized I had fergotten to install opencl-mesa-git again. Got the clover device again.
Still only 1 Platform though.

Re: Can't get OpenCL to work on OS stack with vega 56

Ok, install official mesa again.
Then disable LH' repo & [testing] & [multilib] , run pacman -Syyu

switch to kerberizer llvm-svn repo (or build aur llvm-svn yourself ).
usually my mesa-git builds ok against LH' llvm-svn pacakges, but i haven't tested that for several weeks now


navigate to the folder where you builded my mesa-git, rename/move PKGBUILD and use the adjusted one below .
Once that's installed, reboot and let's see if ocl-icd finally can find opencl-amd platform.

Re: Can't get OpenCL to work on OS stack with vega 56

Is there something I'm missing, or do I only have to run "pacman -S mesa" to switch to mesa from LH's mesa-git? (and remove opencl-mesa-git, and install opencl-mesa afterwards)
Is it "correct" that I should get the 0 Platforms error again, or am I missing a step once again?

Re: Can't get OpenCL to work on OS stack with vega 56

verify you have replaced all packages from lh mesa-git repo by their non-git counterparts by running pacman -Sl mesa-git .

Before you install mesa-no-opencl-git , remove opencl-mesa .

All that should be present is opencl-icd , mesa-no-opencl-git and opencl-amd .
If that gives 0 platforms, try with stable clinfo from [community] repo instead of the clinfo-git .

Behind some of the packages in that list you see [installed]  .

replace those with their non-git counterparts .

Re: Can't get OpenCL to work on OS stack with vega 56

Ok. So I switched back to none git versions of everything provided by LH's repo, removed testing and multilib-testing and LH's repo from pacman.conf, and ran pacman -Syyu.
Should I be "worried" that I've got some testing package versions still installed?

Re: Can't get OpenCL to work on OS stack with vega 56

I forgot reverting from [testing] requires a special option , see https://wiki.archlinux.org/index.php/Of … positories .

You're welcome. It's interesting to figure out how these things work in the real world.

2. Perform a # pacman -Syuu to "rollback" your updates from these repositories.
The second item is optional, but keep it in mind if you notice any problems.

It's optional, but to have consistent results, I'll do it.

Re: Can't get OpenCL to work on OS stack with vega 56

switch to kerberizer llvm-svn repo (or build aur llvm-svn yourself ).

I'm assuming you're talking about https://aur.archlinux.org/packages/llvm-svn/

Re: Can't get OpenCL to work on OS stack with vega 56

yes, since building llvm-svn can be time consuming you could also enable https://wiki.archlinux.org/index.php/Un … s#llvm-svn

Re: Can't get OpenCL to work on OS stack with vega 56

Since clang-svn is a dependency, should I install it from the AUR?

edit: Not sure if I uninstalled at some point during this process...

Re: Can't get OpenCL to work on OS stack with vega 56

If you build aur llvm-svn, clang-svn is also built.
You need several parts of llvm-svn , just build the whole pkgbase and install all *.tar.xz packages it builds.

Re: Can't get OpenCL to work on OS stack with vega 56

Was sick in Bed yesterday, but finally got to continue our experiment.

So I installed the mesa git without opencl, and reinstalled opencl-amd 17.40 since 17.50 isn't in the AUR yet, and platforms are 0.

Re: Can't get OpenCL to work on OS stack with vega 56

I too have this issue. Looks like you've already done everything I tried. hmm

I tried installing mesa-git, llvm-svn, and clang-svn with opencl-amd, but still only Clover reported. The standard mesa in the repos didn't work.

I can see /etc/OpenCL/vendors/amdocl64.icd, but it isn't picked up by clinfo.

Hang in tight there. At least now I know I'm not alone...

Eventually it'll work

Re: Can't get OpenCL to work on OS stack with vega 56

I've switched to normal mesa-git again. opencl-amd has been updated to 17.50 by now. Still only getting clover reported.

Re: Can't get OpenCL to work on OS stack with vega 56

I think the main issue here is that Vega GPUs are not officially supported by the legacy amd OpenCL stack (the one provided by opencl-amd).
You can run clinfo with environment variable OCL_ICD_DEBUG=15 to see that amdocl64.icd is properly found by the ICD loader. The issue is that the call to clIcdGetPlatformIDsKHR from libamdocl64.so returns CL_INVALID_PLATFORM and so the ICD loader declares that there are no platforms to be found.

Vega GPUs are meant to be supported by AMD's new open-sourced ROCm OpenCL stack, but using that requires kernel patches that haven't been mainlined yet... AMD provides a custom kernel with those patches, but based on 4.13, meaning it won't have the DC patches from 4.15, so you'll only be able to run it headless or with the full proprietary amdgpu-pro stack. Using that kernel and the rocm libraries from the 17.50 amdgpu-pro driver (namely libamdocl64.so, libhsakmt.so and libhsa-runtime64.so in /opt/amdgpu-pro/lib/x86_64-linux-gnu), I was able to get OpenCL working on my vega 64.

Re: Can't get OpenCL to work on OS stack with vega 56

So my best bet without spending hours, is wait for the patches to be mainlined...

I'm just gonna continue waiting for now.

Thanks for the reply though!

Re: Can't get OpenCL to work on OS stack with vega 56

following up on Narthorns reply, as far as I'm concerned running it headlessly also will not be an option without some other opencl runtime.

If you take the current "linux-ryzen-amd-staging-drm-next-git" kernel (which is 4.16 atm btw), the kdf error "kfd not supported on this ASIC" goes away, which hints to me this kernel also contains rocm patches (and DC at the same time since X and opengl is working). But I haven't got anywhere further with that with a mesa opencl version. I haven't tested with amdgpu-pro, and will never intend to do so -for very obvious reasons- which might limit my knowledge severely in this topic if that is indeed the only working situation for VEGA and opencl in linux (Yuck!)

I have to be honest, I have a very hard time understanding what this "rocm opencl runtime" is all about, since currently I see completely no possible way to install this on anything other than a debian-based system(Yuck!!). Hell, not even RHEL is supported which is just mind boggling in my eyes.

indeed, this only affects VEGA gpus, as my polaris-10 GPU (580) can use the amd opencl libs without much hassle.

Re: Can't get OpenCL to work on OS stack with vega 56

For now ROCm requires out-of-tree changes to several components including llvm / clang .
The biggest problem with that is that mesa requires llvm, so any system that wants to run a graphical environment AND ROCm needs to support multiple llvm installs.

Running multiple versions of llvm / clang on 1 system is tricky and takes a lot of work.
Debian has a long history of allowing multiple versions of programs/libraries to co-exist and may very well be the best/only distro family to support multiple llvm installs.
(Ubuntu is in my opinion a (big) part of the debian family)
