[SOLVED] Help: Fedora Linux 37 AMD eGPU drivers (Davinci Resolve OpenCL)

groundwork · December 18, 2022, 12:16am

I’m trying to run Davinci Resolve (OpenCL) with my AMD Radeon RX 6700 XT via an EGPU on my Framework laptop

After weeks of trying every guide I could find, the furthest I got was with AMDGPU drivers, the kernel args “radeon.cik_support=0 amdgpu.cik_support=1”, and running mokutil --import /root/mok.der. I was able to open Resolve and it saw my GPU, but pictures and videos wouldn’t render. Minecraft used the GPU seemingly without issue. Minecraft no longer used and Resolve no longer detected my GPU after a reboot, and I had many DKMS problems.

My GPU currently isn’t detected by Resolve and isn’t used by Minecraft.

This is my current configuration:

My current configurations (specifically repositories) are based off of this fedoraproject thread.

OS: Fedora 37
Kernel: 6.0.12-300.fc37.x86_64
Kernel args: ro rootflags=subvol=root rd.luks.uuid=luks-x-x-x-x-x rhgb quiet module_blacklist=hid_sensor_hub nvme.noacpi=1
Display manager: Wayland

Device: Framework Laptop 12th gen (thunderbolt 4)
Secure boot: Enabled

EGPU: Akitio Node Titan (thunderbolt 3)
GPU: Gigabyte (AMD) Radeon RX 6700 XT

AMD Main repo: Index of /amdgpu/5.4.1/rhel/9.1/main/x86_64/
AMD Proprietary repo: Index of /amdgpu/5.4.1/rhel/9.1/proprietary/x86_64/
ROCM repo: Index of /rocm/rhel9/rpm/

All relevant packages (as far as I’m aware) (sudo dnf list installed '*amd-gpu*' '*amdgpu*' '*rocm*' '*roct*' '*hsa*' '*mesa*' '*vulkan*' | grep -v 'procmail|setproctitle'):

GPU Detection 2

The difference here (compared to GPU Dection 1) is I plug in the EGPU at the Gnome lockscreen instead of pre-boot. Doing this allows clinfo to see my GPU.

This is the process I used to test GPU detection in this section:

Shut down laptop
Disconnect EGPU
Boot up laptop
Connect EGPU at Gnome lockscreen
Login at Gnome lockscreen
Open terminal and type in the respective command

1e. glxinfo - CPU is being used rather than the GPU (glxinfo | grep "OpenGL renderer"):

OpenGL renderer string: Mesa Intel(R) Graphics (ADL GT2)

I’ve tried every guide I could find over the past few weeks, but to no avail. Any ideas or suggestions would be really appreciated.

I think you need to get the mesa-va-drivers-freeworld from the RPM Fusion repo and replace the default mesa drivers. Rocm also doesn’t work I think, I heard you need GitHub - sukhmeetbawa/OpenCL-AMD-Fedora: AMD OpenCL userspace drivers for Fedora..

I usually run in my Ubuntu Desktop but Intel and AMD for me was difficult to get running if at all, thus I am still on my NVIDIA GPU.

I run the free version not Pro/Studio though.

Hopefully Intel’s OneAPI can change it.

I also kinda wished Davinci Resolve recognised the Iris XE GPU on Linux like how it is on Windows

I also run the free version of Resolve. I have documented the results of trying the packages you suggested in “configuration b” below. I do realise now that I forgot to remove

I want to clarify that my main goal is to get Resolve to run using my GPU, and I’m using Minecraft as a test application to see if the GPU is functioning at all. If the GPU is working, I expect Minecraft to use it instead of my Intel CPU’s internal graphics. Perhaps I need to do additional setup to get applications such as Minecraft to use the GPU over the CPU?

I’m finding it interesting that in GPU detection test 1’s where the eGPU is connected before booting, clinfo does not see my GPU, but on GPU detection test 2’s clinfo does see my GPU. As lspci always sees my GPU regardless of when I plug it in, it seems like OpenCL drivers don’t kick in unless the GPU is plugged in after the system has booted, just before Wayland starts up as I enter my password into the Gnome lockscreen.

Another point of interest is glxinfo always reports that my Intel CPU’s internal graphics is driving the display rather than my GPU. At the beginning of my first post I mention that time Minecraft was using the GPU and Resolve was able to launch. During that time glxinfo was reporting my GPU being used to drive the display. I believe this was down to the kernel arguments I was using. Perhaps if we make my AMD GPU the primary GPU rather than Intel internal graphics, things may work?

The logs sizes are getting very verbose with each configuration change so I’ll place a when I notice a new result in any given test.

Configuration b

In this configuration I keep all of the packages from the original configuration (a) and run a script which was recommended by the Framework forum.

Added/Changed repositories:
AMD GPU Proprietary: Index of /amdgpu/22.20.5/rhel/9.0/proprietary/x86_64/
AMD GPU Main: Index of /amdgpu/22.20.5/rhel/9.0/main/x86_64/
Copr AMD GPU Pro shims: https://download.copr.fedorainfracloud.org/results/rmnscnce/amdgpu-pro-shims/fedora-$releasever-$basearch/
Copr AMD GPU Core shims: https://download.copr.fedorainfracloud.org/results/sukhmeet/amdgpu-core-shim/fedora-$releasever-$basearch/

Ran script https://github.com/sukhmeetbawa/OpenCL-AMD-Fedora/opencl-amd.sh with options “1. Install-OpenCL-Latest” and “5. Patch-Davinci-Resolve”

These options installed the following packages:

amdgpu-install.noarch
amdgpu-core-shim-0-1.fc37.x86_64  (repo: copr:copr.fedorainfracloud.org:sukhmeet:amdgpu-core-shim)
rocm-opencl-2.0.0.50400-72.el9.x86_64 is already installed.
rocm-runtime-5.3.0-2.fc37.x86_64 is already installed.
libdrm-pro

That script also installed these packages, however I removed them as Gnome would only display a blank screen and flashing cursor on boot. I added them back in a fresh configuration, but clinfo only saw a platform with no devices.

libegl-amdgpu-pro
libgl-amdgpu-pro
libgl-amdgpu-pro-dri
libgl-amdgpu-pro-ext
libglapi-amdgpu-pro
libgles-amdgpu-pro
amdgpu-pro-core
libgl-amdgpu-pro-appprofiles

I also installed rpmfusion freeworld mesa packages as recommended: sudo dnf swap mesa-va-drivers mesa-va-drivers-freeworld --allowerasing && sudo dnf swap mesa-vdpau-drivers mesa-vdpau-drivers-freeworld --allowerasing

All relevant packages (as far as I’m aware) (sudo dnf list installed '*amd-gpu*' '*amdgpu*' '*rocm*' '*roct*' '*hsa*' '*mesa*' '*vulkan*' | grep -v 'procmail|setproctitle'):

GPU detection test b1

This is the process I used to test GPU detection in this section:

Shut down laptop
Connect to EGPU
Boot up laptop
Login at Gnome lockscreen
Open terminal and type in the respective command / test respective application

b1a. Resolve: “Unsupported GPU Processing Mode. Please review the GPU drivers and GPU configuration under preferences.” “CRITICAL_QUIT: GPU Initialization Failed. DaVinci Resolve could not initialize OpenGL. Please ensure that the latest graphics drivers are installed.” These are both individual popups that appear about a second apart.

Configuration c

In this configuration I remove all packages related to my attempts to get OpenCL to work to see the capabilities of my GPU with only the kernel driver as recommended by the Fedoraproject forum.

All relevant packages (as far as I’m aware) (sudo dnf list installed '*amd-gpu*' '*amdgpu*' '*rocm*' '*roct*' '*hsa*' '*mesa*' '*vulkan*' | grep -v 'procmail|setproctitle'):

GPU detection test c1

This is the process I used to test GPU detection in this section:

Shut down laptop
Connect to EGPU
Boot up laptop
Login at Gnome lockscreen
Open terminal and type in the respective command / test respective application

c1a. Resolve: “Unsupported GPU Processing Mode. Please review the GPU drivers and GPU configuration under preferences.” “CRITICAL_QUIT: GPU Initialization Failed. DaVinci Resolve could not initialize OpenGL. Please ensure that the latest graphics drivers are installed.” These are both individual popups that appear about a second apart. I didn’t expect this as I uninstalled all packages, however the script I ran in configuration b claimed to “patch” Resolve. It seems like it is making it try to use OpenGL instead of OpenCL. The script does have the option to reverse its modifications, but I think it would be a good idea to keep them until I get another application such as Minecraft working, as the modifications to Resolve may be necessary for it to work with AMD GPUs on Fedora.

Have we tried using boltctl to authorize the device?

groundwork · January 19, 2023, 10:59pm

Yes, my eGPU is authorized according to boltctl.

My troubleshooting continued at the Fedora forum. However, I would still appreciate any further suggestions anyone from the Framework forum may have.

I plan to update this post if a solution is found.

Matt_Hartley · February 3, 2023, 7:48pm

I’ve begun (be it slowly and initially on Ubuntu) some internal eGPU testing.

My rationale for this approach is here.

I have some community members who are willing to test things on the AMD side of the fence and contribute once I get this public.

So TLTR, relief is coming.

groundwork · February 3, 2023, 11:21pm

Exciting! Thank you for letting me know. I’m hopeful this may resolve my issue.

groundwork · March 10, 2023, 8:46pm

Upon logging in Gnome with my eGPU connected, I experience a lag spike when the desktop is first being displayed, suggesting something related to graphics could be happening.

$ rocminfo

The rocminfo HSA_STATUS_ERROR_OUT_OF_RESOURCES error may be of interest, but I couldn’t find much about it.

A solution!

The reproducible solution for making my eGPU work is to plug an external monitor into the GPU.

Setup

Plug in eGPU and boot system.
Install hertg/egpu-switcher.
Execute sudo egpu-switcher enable and select the eGPU. The egpu-switcher daemon will now start on boot and know which device is the eGPU.
Execute sudo egpu-switcher switch --override.

How to use eGPU

Connect eGPU to laptop.
Connect GPU to a monitor and turn the monitor on, using the GPU input as its source.
Boot laptop

rocminfo, clinfo, radontop and lspci all show what I want to see and applications are using the GPU.

The external monitor can be turned off or unplugged at this stage, but if the laptop goes into suspend, when it wakes up the eGPU will no longer be working and the above commands will fail or show errors.

I plan to buy a HDMI emulator plug so I can do away with the monitor.

The only application which isn’t working with my eGPU at the moment is DaVinci Resolve. It detects the GPU and claims to use it via OpenCL, but the timeline won’t display/play any audio or video (even DNxHD). I’ll likely create a new thread dedicated to this.

Thank you all for your help over the months.

I realised that egpu-switcher claims to only work on Xorg desktops. I use Wayland, so I’ve disabled and removed egpu-switcher from my system and I’m still able to use my eGPU when a monitor is connected to my GPU.

The new, more accurate instructions are as follows:

Setup
Non required in my environment (Gnome Wayland) other than the correct AMD/ROCm packages. If you have already followed the above instructions, run sudo egpu-switcher disable to undo the setup.

How to use the eGPU

Connect GPU to an external monitor via a display cable (HDMI, DisplayPort etc). Ensure the monitor is powered on and is communicating with the GPU by selecting the GPU display cable as its input source.
Connect eGPU to laptop via thunderbolt.
If already in a Gnome session, log out and log back in. If the eGPU disconnects, you will need to restart the laptop for it to work again.
