No OpenCL support for: Ubuntu 16.04.2, RX550 (only this single graphics card), AMD driver 17.10, (64 bit)

I installed drivers as it is instructed in its support page, to the word.

Clinfo told only CPU is present. Installed AMD APP SDK, nothing changed. Installed mesa drivers, only OpenCL 1.1 is available for RX550. Tested if it is really 1.1 with ethereum miner. Miner failed.

Tried --compute while installing, failed again.

Reproducable?

Just out of curiosity: what if I add another vendor's GPU into case, would this card still work as a opengl renderer in ubuntu or oppositely if other GPU is renderer, could this card compute?

System:

Ubuntu alongside windows 10, installed by USB-ISO image.

Re: No OpenCL support for: Ubuntu 16.04.2, RX550 (only this single graphics card), AMD driver 17.10, (64 bit)

I've been having the same issue.

Processor: AMD FX on a Gigabyte 970A MB with 16 GB of Ram (GPU not integrated)

GPU: AMD XFX Radeon RX550

OS: Ubuntu 16.04

Blender: 2.78c

I can play games with the GPU - and it performs oh-so-nice, however I can not get Blender to recognize it exists.  In fact, I can't get Blender to recognize OpenCL.

Blender uses the Cycles rendering engine that uses OpenCL to initiate jobs on the GPU, however I think the way AMDGPU-PRO driver set loads in a different way than the previous fully open source implementation (i.e. AMD independent install of OpenCL using X Server).  Post after post on the various forums give a step by step guide that seems to not apply anymore with AMD's implementation of an all-in-one AMDGPU-PRO install.

This leads me to believe that OpenCL is not recognized or not found by Blender/Cycles.

Here is what I've tried:

Initially I installed version 2.76b (2.76.b+dfsg0-3build1) from the Ubuntu Software Center.  In Blender, I had only the "None/CPU" option for Cycles Compute - there was no "OpenCL/RX550" option that is expected.

I've started to go down the road of learning the programming behind Cycles, AMD OpenCL, and calls to my GPU, but I can say that will be a longer road than to simply ask a developer to look into it.

Please let me know of any next steps or ideas

Thanks for any help! --Dave

Re: No OpenCL support for: Ubuntu 16.04.2, RX550 (only this single graphics card), AMD driver 17.10, (64 bit)

I just brought the card, and I'm very disappointed to have OpenCL support out of the box.

I had checked the linux driver page before the purchase. Nothing mentioned about this issue.

AMDGPU-PRO Driver for Linux Release Notes

Processor: Intel G3930

GPU: ASUS Radeon RX550 4GB

OS: Ubuntu 16.04

Driver: amdgpu-pro 17.10

Tested with claymore95 miner, it says No AMD OPENCL found.

Really need developer to look into it.

Thanks!

Hey everybody... just a quick up date to report that I haven't found anything yet - I'm still lookin, but it keeps looping back to the AMD drivers.  Doh!!

Same thing here. Can't make OpenCL to work with 17.10 on Ubuntu 16.04. Anyone had luck solving this?

Even opencl 1.2 would be enough for me. I already learnt opencl 2.0 with windows but in ubuntu, I need to work work opencl 1.2.

Hi,

From the above descriptions, it looks a driver side issue. I've reported the problem to the concerned team. Once I get any update, I'll get back to you.

There is a 17.30 driver out with 16.04.3 support. All of the 16.04.2 systems out there seem to have been forcibly updated to 16.04.3 so should work OK for you.

The OpenCL 1.1 you are seeing is coming from the upstream open source drivers.
