xekmd-backports

Repository for Intel® Graphics Driver (Xe KMD) backports and development branches.

Overview

This repository contains multiple branches for Intel® Graphics Driver (Xe) backports targeting different kernel versions. The repository is structured to support kernel backports, out-of-tree (OOT) builds, and release management.

Repository Structure

Workflow Overview

kernel-backport → oot-backport → releases

Branches

Kernel Backport Branches	OOT Backport Branch	Release Branch
kernel-backport/main (README) Status: Active (Recommended) Kernel: v6.17+ Description: Primary backport branch with in-tree patches. Latest features: PMU, hwmon, SR-IOV, EU debugging, Xe2 HPG. Can be used for full kernel builds and DKMS generation	oot-backport/main (README) Status: Active Description: Processes kernel-backport branches and applies compatibility layers, DKMS support, and build configurations	releases/main (README) Status: Active Description: Final generated out-of-tree xe and other required modules for DKMS generation
kernel-backport/main_6.14 (README) Status: Active Kernel: v6.14 Description: In-tree backport patches. SR-IOV backports from v6.14-v6.17, VFIO migration support
kernel-backport/main_6.11 (README) Status: Frozen Kernel: v6.11 Description: In-tree backport patches. No longer receiving updates

Management Branch: master - Repository management, documentation, setup scripts, and contribution guidelines

Note: See each branch's README for detailed information and instructions.

Quick Start

Using Git Worktrees (Recommended)

The repository includes a setup-worktree.sh script to manage multiple branches efficiently:

# Create all worktrees (kernel-backport, oot-backport, releases)
./setup-worktree.sh create-worktree

# Create only kernel-backport worktree and generate base kernel
./setup-worktree.sh kernel-backport-only

# Create only releases worktree
./setup-worktree.sh oot-release-only

# List current worktrees
./setup-worktree.sh list-worktree

# Clean up all worktrees
./setup-worktree.sh clean-worktree

After running create-worktree, you'll have:

• kernel-backport/ - Working directory for kernel-backport/main (input branch)
• oot-backport/ - Working directory for oot-backport/main (processing branch)
• releases/ - Working directory for releases/main (output branch)

Manual Branch Checkout

# Check out a specific kernel version
git checkout kernel-backport/main        # Latest (6.17+)
git checkout kernel-backport/main_6.14   # Kernel 6.14
git checkout kernel-backport/main_6.11   # Kernel 6.11 (frozen)
