README.md

build-kernel

This playbook is used to automatically build a kernel with an ACS overrides patch applied. Useful to isolate PCI-e devices to their own IOMMU group for VFIO passthrough.

See this page for kernel configuration details: https://copr.fedorainfracloud.org/coprs/jlay/kernel-acspatch/

Requirements

  • Inventory with one host
    • hosts-local provided 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/

Output:

$ ansible-playbook -i buildserver playbook.yml -b --ask-become-pass
