### 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/
