Revision as of 22:20, 10 December 2019
Contents
Purpose
This guide explains how to add enable Navi 10 based GPUs such as the AMD RX Radeon 5700 XT on Fedora 31.
Background
Linux kernel versions up to and including 5.5 do not support display output when using Navi based cards. A set of kernel patches have been developed ot enable display support. To enable the display the kernel must be recompiled.
Preparations
Disabling fast-reset
AMD GPUs can only have firmware loaded once between resets. This causes issues when the fast-reset support is enabled. Before continuing with this guide, please disable fast-reset by rebooting to petitboot.
First, exit to the shell in petitboot.

Exit and boot back in to Fedora.
Installing the Development Tools
Before building a custom kernel, the development tools must be installed
sudo dnf install @development-tools
Compiling The Kernel
An update kernel with the kernel patches applied must be created. This can be done following the below guide based on https://fedoraproject.org/wiki/Building_a_custom_kernel#Building_a_kernel_from_the_exploded_git_trees
First, checkout the kernel source code. IN this case, we are using the kernel-5.5.0-0.rc1.git0.1.fc32 branch:
[user@bb ~]$ cd ~ [user@bb ~]$ mkdir git [user@bb ~]$ cd git [user@bb git]$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/jwboyer/fedora.git --depth 1 --branch kernel-5.5.0-0.rc1.git0.1.fc32 Cloning into 'fedora'... remote: Enumerating objects: 70582, done. remote: Counting objects: 100% (70582/70582), done. remote: Compressing objects: 100% (67451/67451), done. Receiving objects: 100% (69754/69754), 184.63 MiB | 733.00 KiB/s, done. Resolving deltas: 100% (5304/5304), done. Note: switching to '46d9a88e328bb8135db0a6b58b21cfd3b71ba75e'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by switching back to a branch. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -c with the switch command. Example: git switch -c <new-branch-name> Or undo this operation with: git switch - Turn off this advice by setting config variable advice.detachedHead to false Updating files: 100% (65721/65721), done. [user@bb git]$
Download and apply the kernel patches:

At this point, the new kernel has been installed and can be booted. However, the kernel will not be selected as the default and should only be done once it's confirmed working.
Defaulting to the new Kernel
Before the patched kernel will be automatically booted, the grub configuration file must be changed.

Update the default kernel
The /boot/grub2/grubenv file must be updated. (Replace the text in red as appropriate.)

Configuring The Display
Before continuing, X11 must be configured to use the Navi card instead of the built-in AST device. This must be done by following steps one and two of Troubleshooting/GPU#Workaround_2:_Select_desired_GPU_at_runtime
