ROCm 3.5 - No OpenCL platforms found

[antimatterizer]

Hey! New to ethminer, so please forgive my ignorance. Trying to get it up and running on my hashcat box. Searching some of the issues, I see people mentioning ROCm working, but everything I try ends up with No OpenCL platforms found.

clinfo looks great and hashcat works with OpenCL on two AMD gfx900 cards. I built ethminer from the cloned git, and everything seems to have gone properly. Version listed is ethminer 0.19.0-alpha.0-9+commit.3c62579b

Should this work? Am I missing something?

Thanks!

I seem to be running into similar issue, I am unable to get ethminer to recognize my AMD RX570 4GB card with rocm 3.5.1.

Do you still have this issue? Try to manually add the path to the ocl from ROCm on the txt file from cmake in the main directory of the github repo after cloning... That helped me. Sorry for not providing examples, I'm on cellphone...

[antimatterizer]

Awesome!

I’ll try this.

Could you possibly provide a bit more information on the text file you're referencing? I'm happy to do the legwork from there. I've picked through, and I'm not seeing anything that looks appropriate.

Thanks!

After building from source I receive this error. (I tried: v0.19.0-3+commit.bc628f6c, v0.18.0)

I have tried to edit the value to the location of opencl during cmake, hunter overrides what I specify? actual location: /opt/rocm/opencl hunters location: /home/$USER/.hunter/_Base/4b894e1/fdb8df4/cb395ce/Install/lib/cmake/OpenCL

CMakeLists.txt

but I just found out there is no direct reference to the ocl path on that file...

I have some time now, will try to install rocm and figure that out, but I'm running on a different GPU... If First I get the same error then I'm able to fix it, I'll provide details!

[Josevora]

@ianzur did you install rocm-opencl-dev ? maybe you guys are only missing the ocl all together!

[ianzur]

I wish, it is installed on my machine. I believe it is included in the rocm-dkms meta-package.

[Josevora]

DONE!

I've installed ROCm 3.7, and I've got the same output: "No Opencl Platforms Found" Then i did something a little bit UGLY, that worked:

I Went to: /opt/rocm/opencl and ran this command: sudo cp -r * / that copied the content of the folder to the main folders where Ethminer is looking for the OpenCL files!! Built and Compiled again and VOILÁ! WORKING!

Tell me if it worked for you guys!

[antimatterizer]

This did indeed work. In the name of cleanliness and also curiosity, I dove into this a bit and found that only copying the contents of /opt/rocm/opencl/lib to /lib is necessary.

Thanks!

I assumed your method (@Josevora ) would work, but I didn't like the ugly...

I hacked on the ethminer/libethash-cl/CMakeLists.txt file, and was able to get cmake to find my installed OpenCL at /opt/rocm/lib/libOpenCL.so

1. Remove the OpenCL hunter had downloaded? cmake was still finding this version first after my hacking. rm ~/.hunter/_Base/4b894e1/fdb8df4/cb395ce/Install/lib/libOpenCL*

[ianzur]

For an official solution we should to add a build flag for ROCm to rely on cmake to find system OpenCL library similar to the soln for Mac.

PLAN:

• [x] add build flag, "USE_SYS_OPENCL"
• [x] default FALSE (rely on hunter); unless APPLE then TRUE
• [x] change if(APPLE) -> if(USE_SYS_OPENCL)
• [x] update build docu

I'll link a PR late tonight.

Got it to compile and now recognize the rocm GL device, but the performance is not as good as the legacy amd driver. Looks like that might be related to the inability to load ./kernels/ethash_gfx803_lws192.bin. I guess the kernels are not compatible with rocm? Anyone else seeing this?

Following up on this -- I was interested in checking hashrates of the RX580 rig, so I spun up NiceHashOS. This uses the AMDGPU drivers and gets ~22Mh per device even at lowest power level. Ethminer in Ubuntu get's about ~14. Rejecting the kernels definitely has a performance hit. I'm not concerned, as I was just tinkering on my hashcat rigs, but I thought the information might be helpful if others are interested.

with rocm-2.9 I was not getting good luck with solutions above, but I managed to compile it by cmake options:

cmake .. -DETHASHCUDA=OFF -DETHASHCL=ON -DUSE_SYS_OPENCL=ON -DAPICORE=ON -DOpenCL_INCLUDE_DIR=/opt/rocm/opencl/include -DOpenCL_LIBRARY=/opt/rocm-3.9.0/opencl/lib/libOpenCL.so.1.2
CPATH=/opt/rocm/opencl/include cmake --build .

[herandol]

Thanks for the commands @mask8 it is working well for me.

[ekuznetsov139]

No need to mess with cmake. Just do

LD_LIBRARY_PATH=/opt/rocm/opencl/lib ethminer ...

[trougnouf]

I haven't tried going back to the "official" AMD driver, but now that they use rocr I guess they would both behave the same way (cmake flag needed, unable to load the binary kernel, worse performance).

Has anyone tested AMD >= 20.45 driver?

edit: tested, same performance and same runtime metadata section not present in ELF program binary error with opencl-amd 20.45 (Driver version 3188.4) and rocm-opencl-runtime (Driver version 3212.0)

edit: performance shown in ethminer console goes from around 22 on rocm to 37 on amd 20.40. Not confirmed on the pool yet (and I may not get an accurate figure because I started mining yesterday and I have a mixed AMD Vega 56 / Nvidia GTX 1070 machine. The Nvidia card has a reported 25 MH/s).

edit: performance shown by the pool is much better with the open-source rocm driver

The RX 580 doesn't work with phoenixminer either only teamredminer works.

Cannot install rocr as the 20.50 driver cannot build on 5.10.0-4 kernel it's 5.9 or lower.

Running Debian bullseye/testing Ryzen 5 3600 also have a mixed rif. Primary videocard is a GTX 1070 26Mh/s reported ethminer and a RX 580 24.8Mh/srunning with teamredminer. I have installed the 20.50 drivers AMDGPU-Pro Opencl drivers only. Installed OpenCL drivers with the following command: amdgpu-install --opencl=legacy --headless --no-dkms I cannot get the RX 580 to work with ethminer 0.18.0.

Did you try compiling ethminer? See https://github.com/ethereum-mining/ethminer/issues/2003#issuecomment-729335031

I got it working with a Dockerfile I wrote. However, I do see the failed to load binary kernel error, so maybe it can do better if I get it to use AMD's ROCm library.

Here it is, maybe someone can tweak it. Note that cmake / hunter fail to download boost 1.66.0 so you need to provide the file (see section marked with XXX) =\ This Dockerfile will actually compile ethminer from source as part of the build process. It's a pattern I've developed
