Guide | Install AMD OpenCL on: Pop!OS & some Ubuntu Derivates | Linux, amdgpu, amdgpu-pro, rocm, rocr

[Tpal]

Hey,
I’m going to show you one way, how to install the OpenCL drivers / headers only.
In a relatively simple way.
After some back and forth, to get OpenCL on my Pop!OS computer running,
I’ve learned some pitfalls to be solved.

Disclaimer
The installation routine shown: does not correspond to the AMD procedure.
It bypasses some of the security / compatibility checks.
I do not accept any liability or guarantee for damage to: the system, hardware and/or software.
Use at your own risk.
With that said and out of the way, let’s begin.

Guide

Scenario#1
You don’t have installed AMD drivers: (OpenCL ONLY)

1. Go to AMD Driver support
Download the Driver Tarball for your GPU → for Ubuntu Distributions.
OR
1.1 Get the Latest universal package | AMD.com (Radeon™ Software for Linux® version 21.10 for Ubuntu)
Please check the compatibility of your graphics card in the section: (Compatibility with the AMD Radeon ™ product family)

2. Extract the Tarball and open the new Folder
(amdgpu-pro-20.10-1048554-ubuntu-18.04) in my case.

3. Edit the (amdgpu-install file) for compatibility
Double-click on the amdgpu-install
- A text editor should open

• Search for Ubuntu (Ctrl f)
  -add | pop to the case list
  - Once the new case has been added, press (Ctrl + s) to save the file and close the text editor.

• Note: This step is the key which will add the operating system as a compatible distribution.
  

4. Right-click on an empty space. In the same folder where the file “amdgpu-install” is located->

• Right Click → “Open in Terminal"
  Now you should have a terminal window with a path pointer, to your downloaded Driver Folder.

5. In the Terminal
Now the fun begins, including the installation process.

OS 20.04~20.10:

Driver Version:
20.04.2 → Revision: 21.10

• AMD GPU
  ./amdgpu-install --no-dkms --opencl=legacy,pal

• AMD GPU-Pro | mainly for PRO GPU variants.
  ./amdgpu-pro-install --no-dkms --opencl=pal,legacy

Old Driver Version/s:
18.04 → Revision: 20.30,
18.04.5 → Revision: 20.40

• AMD GPU
  ./amdgpu-install --no-dkms --opencl=legacy,pal --headless

• AMD GPU-Pro | mainly for PRO GPU variants.
  ./amdgpu-pro-install --no-dkms --opencl=pal,legacy --headless

• AMD GPU ROCm/ROCr | not fully supported by Blender
  ./amdgpu-install --no-dkms --opencl=rocm --headless

If a warning message like “Build Error 1” or similar is displayed, do not restart your system!
Follow Scenario 2 below, properly uninstall the AMD GPU drivers and start the installation process again.

Some explanation for the --Flags

• Choose the right OpenCL: header package for your hardware and application.
  If you are not sure, please refer to the links below.
  Old and semi-old GPU’s
  --opencl=legacy,pal
  Vega10 or newer GPU´s
  --opencl=rocm
  ROCm overview:
  Informations about ROCm/ROCr
  Application-specific limitations of ROCm and Blender | developer.blender
  ROCm Compatible Hardware | GitHub
  Further instructions for installing ROCm | rocmdocs.amd

• –headless should assure
  -no Display driver
  -no DKMS Firmware
  -no Vulkan and/or OpenGL librarys get installed.
  (You don’t need them, since Pop!OS uses Mesa Drivers.)

• –no-dkms
  This flag prevents a kernel rebuild and the installation of:
  amdgpu-pro-firmware and other DKMS packages.
  Note: POP!OS is incompatible with these drivers.
  DKMS Rebuilding leads to errors.
  This can/will result in a non-bootable OS.

6. Installation

As you can see there are some dependencies required for the installation.
As long as the package names do not contain references such as →
DKMS, Firmware, Vulkan or OpenGL.
You are ready to go. Press Y and confirm.

7. Check your installation in the terminal by typing: clinfo
If the installation was successful:
it should answer: number of devices: 1 or
(If you have more than one OpenCL compatible device it should output something >0.)

8. Reboot your System

9. Check Blender

If the result looks like the picture above:
Congratulations, you have just successfully installed AMD proprietary OpenCL on Linux!

TROUBLESHOOTING

If not: Blender and / or Clinfo do not show me compatible OpenCL devices:

• It may be helpful or even necessary to install the following package manually:
  sudo apt install opencl-headers ocl-icd-libopencl1
  Thanks to Aisyk

• Flat pack versions of Blender do not work properly with OpenCL.
  Thanks to Aisyk, Blenderis

• It can be helpful to test one of the daily builds.
  They contain some hotfixes for new hardware and solve version problems.
  It is possible that the OpenCL hardware detection and / or other bugs have already been fixed with this version.

• Note: sometimes you need to reinstall Blender or move it to another Place.
  (If Downloaded from Blender.org as Archive.)

• If Blender fails to start, artifacts appear in eevvee or the Cycles kernel build is unsuccessful.
  Check whether you are using the following drivers: : 20.04.1 / Revision: 20.45 or 20.04.1 / 20.04.2 Revision: 20.50
  If this is the case: These versions are neither compatible with Blender nor with operating system versions <=> 20.04.

• PPA’s
  When using PPAs like: “oibaf” or similar sources for Mesa driver packages.
  Make sure to uninstall them before installing OpenCL.
  As this can lead to conflicts or other problems.
  they can be reinstalled after a successful OpenCL installation.

• When you come across this message:
  "ERROR: using --no-dkms with a pro install is invalid. Did you want to run the following instead amdgpu-install --no-dkms"
  You can try this Procedure thanks to: pzona
  OR
  Use the non-PRO installer, if your GPU is not a Pro variant.

Scenario#2
Uninstall correctly:
You tried to install AMD drivers but an error occurred.
OR
You can no longer perform a proper uninstall, but your operating system is bootable

1. go to your downloaded amd driver folder and open a terminal->
like in step 4 @ Scenario#1 and type:

• ./amdgpu-pro-install --uninstall
• ./amdgpu-install --uninstall

If you have already executed:

• amdgpu-uninstall OR
• amdgpu-pro-uninstall
  Result could be:
• “The amdgpu driver is already installed or was not uninstalled correctly. Please fully uninstall the driver before proceeding with installation You can try running this install script with the --uninstall option to clean up the previous installation.”

1. Not a problem, just open a Terminal and Type:

• OS 18.04~20.04:
  sudo apt install amdgpu-dkms libdrm-amdgpu-amdgpu1
  Thanks to Blenderis
  This will refresh the Dependency list. Especially the amdgpu-pro-pin.

• OS 18.04
  sudo apt install amdgpu-dkms libdrm-amdgpu-amdgpu1 libdrm-amdgpu1libdrm2-amdgpu

4. Folow Step 1 @ Scenario#2

3. Reboot your System

Beginn with step 1 @ Scenario#1

Scenario#3
Your system is un-bootable.

Note: this steps will solve a un-bootable OS. (if you have access to the Terminal.)
1. Press/Try (ALT F2)

2. In Terminal Type:

• cd Downloads/amdgpu-pro-xx.xx-xxxx-ubuntu-xx.xx
  (Note: i assume your downloaded Driver Package is in the Downloads Folder. If not change it according to your path.)
  Please replace the “x” with the numbers of your Driver folder name.
  you can type ls to list the entities.

Once your Path matches the place where your downloaded Driver folder lies.
Type:

• ./amdgpu-pro-install --uninstall
./amdgpu-install --uninstall

3. Reboot your System

(Note: once your system is bootable again)
Beginn with step 1 @ Scenario#1

[silex]

Great explanation. Also, new drivers, nice!
Did you check how’s the performance comparing to 19.50?

[Tpal]

Unfortunately I have no comparison for the latest drivers. This was my first attempt on PopOS.
However, since I had some pitfalls, I thought it wouldn’t hurt to document the solutions I´ve found.
So that others have a working solution.
Thanks for the kind words.
Glad if it helps someone.

[Blenderis]

I just wanted to provide some feedback since I am on PopOS 20.04.
Your instructions do not seem to apply. The --no-dkms does not work.

When running amdgpu-pro-install command:

ERROR: using --no-dkms with a pro install is invalid.
Did you want to run the following instead?
amdgpu-install --no-dkms

When running the ./amdgpu-install --opencl=legacy,pal --no-dkms --headless it seems to work better from an installation perspective.

./amdgpu-install --opencl=legacy,pal --no-dkms --headless

However blender 2.83 installed with flatpak does not recognize any card.

Only blender 2.82a recognizes the card.

If somebody has any guidance on why that would be the case, I would be interested in understanding

[Tpal]

Hey, sorry for the late response. Also thanks for your feedback.

As far as i know, the Install File without pro can not install opencl.
Just the Pro Variant has included the Open CL Packages. (I’ve updated the Instructions, now it should work with the Pro version.)

If Blender still don’t recognize your Open Cl installation after reboot. Try to move the blender Folder to a different Location. This mostly helped me.

Edit: @Blenderis i’ve updated the Instructions. Thanks again, for this hint with the incompatible Command. i’ve mentioned you on the relevant spots. Hope thatś okay for you.

[Blenderis]

@Tpal Thanks a lot for updating your instructions and integrating the feedback. Your post was useful in the first place so no worries at all.

[javier]

Thanks a bunch for sharing such a complete tutorial Tpal
I went to AMD Driver support , but at arrival it’s obvious that the website assumes that you need this driver for Windows. How to choose the one for Linux Pop OS ?

---

Never mind, looks like I found it.
Unfortunately I also learned that my new laptop having only AMD Radeon Vega 6 doesn’t really qualify as Radeon Pro graphics, which is required to use the AMDPro driver

[javier]

No worries
I have not found a solution yet. I am taking a break for now.
The GPU is AMD Radeon Vega 6 Graphics, from a Lenovo IdeaPad Flex 5 14" (2020), AMD Ryzen 4500u.
I’ll try to add more info about my issue later. Thanks in advance Tpal

[javier]

Wow, this is amazing! Thank you so much for sharing this valuable info! I appreciate the time you put into it
I’ll look into this asap!

[Azamezeobi]

i get this particular error when trying to install the amdgpu pro following your guide

.

[Azamezeobi]

Thanks i am using an AMD Radeon HD 6470M with 1GB dedicated DDR3 video memory on a pop 20.04 os. i tried all, it still brings out the same error

[Azamezeobi]

its only the mesa,-opencl that worked. i hope all this errors doesn’t have to do with my os installation.
after installing the mesa opencl, how do i setup blender from here. Thanks very much

[Azamezeobi]

Thanks. after using step one and two and checked with clinfo command and i got this in the screenshot. does it mean the opencl is installed properly. if it is i can’t still get blender to see it.

[Blenderis]

@Tpal Just to update this thread following my upgrade to Pop’OS 20.10 and upgrade to amdgpu version 20.40.
Upgraded Pop’OS 20.10
Uninstall the amdgpu drivers (v20.30) according to your steps as I hit the message for previous version being installed
Install the amdgpu drivers (20.40)
Launch blender v2.83.5 with OpenCL support

I thought I would share if you want to update the tested version of amdgpu in your instructions.

[Blenderis]

No change required to the steps. Just followed them and can confirm it works fine.

Thanks again for the original post.

[Aisyk]

Hi !
In the road to install OpenCL render on my PopOS 20.10 with my RX5500XT, i’ve found your thread. Thanks for your informations !

But… it doesn’t work for my system, OpenCL isn’t selectionnable on Blender
My clinfo : aisyk@pop-os:~$ clinfoNumber of platforms 2 P - Pastebin.com

I’ve installed with this command :
./amdgpu-install --no-dkms --opencl=legacy,pal
AND tested with this : ./amdgpu-install --no-dkms --opencl=rocm

No errors reported everything is installed fine, reboot ok…

(and there is an little error on your paragraph " Some explanation for the --Flags " → –no-dksm you mean --no-dkms )

[Aisyk]

Ok,

So i could have the OpenCL installed and i know why it don’t worked before.

2 things :

• don’t install crappy flatpak applications (Blender 2.83.5 from deb repositories is functionnal)
• and i installed this : sudo apt install opencl-headers ocl-icd-libopencl1

[pshk4r]

Thanks for the tutorial!

I run Pop OS 20.10 and have downloaded the latest AMd drivers (amdgpu-pro-20.40-1147286-ubuntu-20.04) and the installation via /amdgpu-install --no-dkms --opencl=rocm goes without any issues.
But unfortunately, the clinfo still shows 0 devices, and the OpenCL is not visible to any apps, including Blender.

@pshk4r

But unfortunately, the clinfo still shows 0 devices, and the OpenCL is not visible to any apps, including Blender.

You try reinstalling the package ocl-icd-libopencl1:
sudo apt reinstall ocl-icd-libopencl1

[pshk4r]

Thank you @YAFU but that hasn’t helped either
