build-kernel
This playbook is used to automatically build a kernel with an ACS overrides patch applied as well as Valve's fsync patches.
The ACS patch is useful to isolate PCI-e devices to their own IOMMU group for VFIO passthrough.
The fsync patches improve Proton performance.
See this page for ACS kernel configuration details: https://copr.fedorainfracloud.org/coprs/jlay/kernel-acspatch/
Requirements
- Inventory with one host
hosts-localprovided as a sample inventory for localhost
- This host must be running Fedora (builds use mock)
Usage
Notes
Target Fedora version is controlled by the variable fedora_version in ./playbook.yml
Patch to apply is determined by the patch_file variable, stored in ./payload/
Patches for many different kernel versions provided, the highest version available should be current/working. Patch versions only change when diffs change.
Output:
$ ansible-playbook -i buildserver playbook.yml -b --ask-become-pass
