Speed is always 0 Mh / s (OpenCL old version?) #1294

Closed aashidham closed 5 years ago

aashidham commented 6 years ago

Hello, I have Ubuntu 16.04.4 LTS (xenial) with a Radeon RX 550 Series graphics card. I'm trying to use OpenCL 1.1 to mine with it. However, ethminer just gives back 0.00 Mh / s when I'm trying to mine with it.

Here is the output for ethminer:

    NOTE:   your OpenCL library declares to support OpenCL 1.2,
        but it seems to support up to OpenCL 2.1 too.

I had do apt install mesa-opencl-icd to get this to work. I have the drivers from amdgpu-pro-18.20-606296 installed.

I tried installing a newer OpenCL ICD loader (sudo gdebi opencl-amdgpu-pro-icd_18.20-606296_amd64.deb) installed but this stopped clinfo and ethminer from recognizing the graphics card.

I also tried installing newer OpenCL libraries from the AMD drivers (libopencl1-amdgpu-pro_18.20-606296_amd64.deb and opencl-amdgpu-pro_18.20-606296_amd64.deb) but this had no effect.

Here are all the packages that are available from the AMD driver tarball:

How do I either correctly install newer OpenCL libraries on Ubuntu or make OpenCL 1.1 work with ethminer?

aashidham commented 6 years ago

@jean-m-cyr @AndreaLanfranchi @chfast any insights about this?

aashidham commented 6 years ago

^ ping on this?

jean-m-cyr commented 6 years ago

I'm not ignoring this issue. I am just not able to reproduce it on my single 480 GPU. I'm not sure what 'Clover' is! I generally focus on Nvidia stuff.

@ddobreff Do you see any problem with this configuration?

ddobreff commented 6 years ago

Install opencl dependencies from 18.10 amdgpu-pro package. AMD added support for Vega and Lexa since this package.

aashidham commented 6 years ago

What is the apt name for this package? Is it just amdgpu-pro?

I don't think there's a apt package for that version. I think you have to download and follow instructions here: https://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-for-Linux-Release-Notes.aspx

aashidham commented 6 years ago

OK, well that's the exact link I followed already; thats the AMD tarball that contains ~/projects/graphics_mining/amdgpu-pro-18.20-606296. Are you saying I should downgrade from 18.20 to 18.10?

If the latest version (18.20) is fine, then maybe it would help to specify exactly which of the opencl packages above I should install that I haven't tried already? I've already tried libopencl1-amdgpu-pro_18.20-606296_amd64.deb and opencl-amdgpu-pro_18.20-606296_amd64.deb and they haven't worked, as I mentioned in the original post.

ddobreff commented 6 years ago

All packages have dependencies, just track dependencies of libopencl/opencl/amdgpu-core, you can use dpkg-deb -R to unpack amdgpu-core and remove amdgpu-pro-dkms package requirement.

ddobreff commented 6 years ago

Do you still have the issue?

aashidham commented 6 years ago

Yes. I don't get which of the packages to install. I have trouble understanding your prior comment.

Just install the hybrid driver amdgpu-pro-18.20 and it should work.

aashidham commented 6 years ago

Like I mentioned in the original post, those drivers are the first thing I installed.

chfast commented 6 years ago

@aashidham your OpenCL driver is not able to compile the OpenCL kernel. The Clover OpenCL implementations you are using is production ready and does not give good performance. You should install amdgpu-pro driver.

ddobreff commented 6 years ago

He stated that the driver is installed but the presence of Mesa/clover is also noted. Please remove mesa opencl installation and install amdgpu-pro-18.20 cleanly.

aashidham commented 6 years ago

Apologies for my ignorance, but how do I remove Mesa / clover and do a clean install on Ubuntu 16.04? What specific packages should I delete / install? Still not clear about the specifics.
