Bazzite GNOME ROCm

This project creates a customized Bazzite GNOME image with a longterm kernel (6.12) to support ROCm on AMD hardware.

Contents

• recipes/recipe.yml: The BlueBuild recipe to create the customized image

Image Preparation

The image can be built using BlueBuild:

bluebuild build

This will create a local container image localhost/bazzite-gnome-rocm:latest that includes:

• Longterm kernel 6.12 (ROCm compatible)
• Kernel modules from the longterm kernel repository

Installation

Verified Image (Recommended)

To install the verified image, use the following command:

sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/btekv4/bazzite-gnome-rocm:latest

Unverified Image

To install the unverified image, use the following command:

sudo rpm-ostree rebase ostree-unverified-registry:ghcr.io/btekv4/bazzite-gnome-rocm:latest

After reboot, you'll have a version of Bazzite with the ROCm-compatible kernel.

Verifying it works

Kernel verification

To verify the system is using the correct kernel:

uname -r

You should see a kernel version starting with 6.12 (longterm kernel).

ROCm verification

To verify that ROCm works correctly:

rocminfo

Specific Problem Solved

This project solves the compatibility issue between ROCm and newer Linux kernel versions. ROCm requires specific kernel versions (in this case, 6.12 longterm) to work properly on AMD hardware, while Bazzite by default uses newer kernels.

Changes Made

To enable full ROCm compatibility, the following adjustments were made:

Repository Configuration

A COPR repository is added to provide the longterm kernel:

• https://copr.fedorainfracloud.org/coprs/kwizart/kernel-longterm-6.12/repo/fedora-43/kwizart-kernel-longterm-6.12-fedora-43.repo

Installed Packages

The longterm kernel and its modules are installed to replace the default kernel:

• kernel-longterm
• kernel-longterm-core
• kernel-longterm-devel
• kernel-longterm-modules
• kernel-longterm-modules-extra

This ensures maximum compatibility with AMD GPUs using the ROCm stack.

ISO Creation

If you are building this on Fedora Atomic, you can generate an offline ISO following these instructions.
Note: Due to size constraints, ISOs cannot be freely hosted on GitHub; alternative hosting must be used for public distribution.

sudo bluebuild generate-iso --iso-name bazzite-gnome-rocm.iso image ghcr.io/btekv4/bazzite-gnome-rocm:latest
