Guide | Install AMD OpenCL on Pop!OS, Ubuntu & some Derivates

Tpal · January 17, 2021, 1:33am

Hey, i will show you a way to Install only the OpenCL Drivers/Headers. In a relatively hassle free manner.
After some fiddling to get OpenCL running on my Pop!OS Machine,
I’ve learnt some pitfalls to resolve. With that said, let’s get started.

Thanks to all Contributors.

NOTE: Latest driver 20.04.1 / Revision: 20.45 is incompatible on Pop!OS 20.10

AMD has apparently changed the openCL headers internally from:
(Pal / Legacy) to (ROCm / ROCr),

Most likely all RX 6000 series and
all models that do not offer older driver versions are incompatible for this method at the moment.

Models with older driver available like:
Radeon Software for Linux Drivers for Ubuntu:
18.04 | Number: 20.30
18.04.5 | Number: 20.40
should still work with this method on Pop!OS 20.10.
./amdgpu-install --opencl=pal,legacy --headless --no-dkms

Tested driver 20.04.1 / Revision: 20.45 on Pop!OS 20.04 and FerenOS 20.04

Results:
1. Installation and kernel update/build were successful.
2. Strange rendering artefacts and pixel mush in (eevee -> Render Mode)

3. So far I’ve had no luck and Blender doesn’t finish kernel compilation (Cycles) without crashing.
So the latest driver doesn’t seem to be fully compatible with Blender ATM.
maybe a little love and optimization can change that in the long run.

Maybe it’s because of this:
WARNING: PAL OpenCL has been dropped in favour of ROCr.ROCr OpenCL will be installed instead of PAL OpenCL.Please advise that this option is deprecated and will be removed in future releases. Please use --opencl=rocr instead.

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.

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 purposes
double-click on amdgpu-install
-Some text-editor should appear

Search for Ubuntu (Ctrl f)
-add “|pop” to the case list
-once the new Case is added press (ctrl s) to save the file and close the text-editor.

Note: This step is key, this will add Pop!OS as a compatible Distribution.*

4. right click on some free space in that folder where the “amdgpu-install” File is ->

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 beginns, also the Installation Process.

Pop!OS 18.04~20.10:

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

AMD GPU Pro
./amdgpu-pro-install --no-dkms --opencl=pal,legacy --headless
if you encounter this Message:
“ERROR: using --no-dkms with a pro install is invalid.\nDid you want to run the following instead \namdgpu-install --no-dkms”
Try this Procedure thanks to: pzona

AMD GPU Pro ROCm | not fully supported by Blender
./amdgpu-install --no-dkms --opencl=rocm --headless
Note: Thanks to Blenderis for the incompatibility hint.
That’s the new Command for newer OS’s. Sadly without dryrun flag.
So you need to watch extra carefully if there are no DKMS packages.

If you encounter a warning Message like “Build Error 1” Or simmilar, dont Reboot your system!
Follow Scenario#2 below and uninstall AMD-GPU Drivers properly and restart your install processdere.

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 The X.Org Mesa Drivers.)

–dryrun Is an auxiliary flag, it simulates the installation process, shows you the packages to be installed. But without any actual installation. Remove it to start the final installation.

–no-dkms
is important!
This flag prevents a kernel rebuild and the installation of:
amdgpu-pro-firmware and other DKMS packages.
Note: Pop! OS is not compatible with these drivers.
The DKMS rebuild will result in errors.
This can lead to a un-bootable Pop!OS.

If it looks like in this Picture, you are ready to go.
Just remove The —dryrun Flag and let the Installation-process begin.

6. Installation without --dryrun Flag

hotinstallation1743×966 170 KB

As you can see, there are some dependencies needed to install.
As long as there are no hints in the Packagenames like ->
DKMS, Firmware, Vulkan or OpenGL. it’s good to go.
Press Y and Confirm.

7. Check your installation in Terminal by type: clinfo
if the installation was successful:
it should response: Number of devices: 1 or
(if you have more than one OpenCL compatible Devices, it should show something >0)

8. Reboot your System

9. Check Blender

Result680×575 55.9 KB

If the Result looks like the Picture above:
Congratulations, You’ve just successfully installed AMD´s proprietary OpenCL on Linux!

TROUBLESHOOTING

If not: blender and/or clinfo, does not show me any compatible OpenCL device:

Note: Thanks to Aisyk for his research, according to his findings:
it might be helpful or necessary to install the following package manually:
sudo apt install opencl-headers ocl-icd-libopencl1
his attempts also showed:
flatpack version of blender, does not work properly for using OpenCL.

It can also be helpful, to test out one of the daily builds.
They contain some hotfixes for new hardware and tackle version problems.
It is possible that the detection of the OpenCL hardware and / or other errors 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)

Scenario#2
You have tried installing the AMD Drivers but somethings went wrong OR
you can’t perform a proper Uninstall anymore.

If you just want to Uninstall the Drivers properly.

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:

Pop!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.

Pop!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

Hope this is helpful.
-Cheers Tpal

Was it helpful / successful for you?

If not, please let me know your:
-Pop!OS/Linux version + (kernel version optional)
-GPU series / model
-Driver edition + revsion number
Error message/s (logs, images optional)

If you were successful with a:
-driver version
-GPU model / series
-Kernel / Linux version
I have marked as incompatible.
Please let me know. Also what steps it will take to make it work.
This will help keep this guide updated.
Thanks in regard.

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

Tpal · November 3, 2020, 7:41pm

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 · June 30, 2020, 12:35am

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 · August 14, 2020, 1:55pm

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 · August 16, 2020, 11:22pm

@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 · August 31, 2020, 1:37am

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

Tpal · September 20, 2020, 12:17pm

hey, also sorry for the late response and thanks for the feedback.

Did you find a solution for yourself?

If no: I’ll be happy to see if there is one.
(Could you tell me the exact name of your Apu/Gpu?)

if yes: can you tell me what the solution was?
(I’ll happily add it to the post, with some quotes to you of course. )

javier · September 20, 2020, 6:16pm

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

Tpal · October 2, 2020, 6:20am

Hey, thanks for the further informations.
I´ve done some research, for the specific Soc.
Iám not 100% sure if i get your problem fully, so i try to answer as many questions as i can think of at the moment.

if you struggle finding the right driver Pakage for your hardware,
This Hardware is Pretty new, could take a while till amd will publish offical Linux drivers.
But you are not the only one who asks for this: on Phoronix are active topics about this.

Or

you are not sure if your hardware is applicable for openCL.

Short anwser -Yes it is

if you are into some troubleshooting and testing, you could try to use existing driver packages
Like this:

RX VEGA 64 Driver
But you should only try this, if you think you are ready and able to fix upcoming probems.
I dont want to destroy your system where is no need for.

I’m not sure if this will work, but since you only need to install the openCL drivers,
there should not be a big problem to following the tutorial with this Package.
-Ubuntu x86 64-Bit

some of the impatient ones have already done some research of ther own for that:

VEGA Driver for R5 4500u Disscusion

I wish i could help you more, but as it looks, there are no official drivers at the moment.
But i’m pretty sure they will come.

javier · September 21, 2020, 1:12am

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!
J.

Tpal · September 21, 2020, 10:50am

No problem mate, thanks for the kind words.
Glad if it will help.

if you want to try this approach, an update would be nice, whether this will work.
Might help others with similar problems.

I keep my fingers crossed and good luck.

P.s just a thought, I’ve seen the notebook/convertible on some pictures.
Looks pretty thin to me ,(I can only imagine how well the cooling design will perform).
Nice for traveling, but keep in mind rendering is a pretty torturing process.
Especially on GPU and even more if the GPU is embedded in the CPU die.
Keep an watchful eye on the temps, with appropriate monitoring software.

Azamezeobi · September 27, 2020, 2:58pm

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

.

Tpal · September 28, 2020, 1:01pm

Uff, Looks like AMD is changing their Options Flags pretty often. I will look into it.
Thx for the information mate .

Azamezeobi · October 1, 2020, 10:02pm

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

Tpal · October 2, 2020, 6:54am

What’s about:

./amdgpu-pro-install --opencl=legacy,pal --headless
Or
./amdgpu-pro-install -y --opencl=legacy,pal --headless
Or
./amdgpu-pro-install -y --opencl=legacy,pal --headless --px
(cross your fingers that you don’t need the px option.)

Focal Fossa package: information/dependency’s

If none of these commands will work, the only option are mesa icd’s.
sudo apt install mesa-opencl-icd

However, I have not yet made any experience / attempts with it.

Azamezeobi · October 2, 2020, 9:08am

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 · October 7, 2020, 9:13am

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.

Tpal · October 7, 2020, 11:56pm

Looks pretty good so far.
If blender now also shows your graphics card as an opencl device:
Prefenrences -> System -> OpenCL
Is the process successfully completed.

This Post sounds also kind of Interesting:
(in terms of strip down and use AMD Non Free Driver OpenCl Files and Use the Mesa Loader. You´ve installed already.)
Can't enable OpenCL for AMD RX 5700 XT on Linux

EDIT:

If Blender don´t show your GPU as a OpenCL Compatible Device, it´s problably cause of this:
https://developer.blender.org/T50522
https://developer.blender.org/T53935

Mesa drivers are not supported.
A piece of news that I just learned myself.

The OpenCL Version is also wrong: it should be Version 1.2 instead of 1.1.
But it looks like there is no stable / acceptable MESA port for it, as I can see from the sources above.

EDIT #2:

the very last possibility would be, to try a newer driver package like this one.
https://www.amd.com/de/support/graphics/radeon-500-series/radeon-rx-500-series/radeon-rx-580
with this Package you can follow the Tutorial above.

Since only opencl should be installed, without additional drivers this could work.

However, it is very far from your actual hardware and OpenCl version.
This could have a significant impact on your system. (Watch the Console Carefully for Errors and such)
I am also unable to say whether error-free and /or crash-free rendering will be possible.

But I would like to refer to this very last variant, albeit very risky.

Unfortunately, these are the last few ways I can imagine that they could work to install opencl on your system.
If these don’t work either
I’m afraid I can’t give you any other solutions / options.

I am sorry.
Perhaps there are people who have already found a solution to similar situations
and can help.

Blenderis · October 24, 2020, 3:35pm

@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.
