### build_kernel ### 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. 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/ 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)
