# Based on the build-linux.sh script from the Mutter project:

# https://gitlab.gnome.org/GNOME/mutter/-/blob/main/src/tests/kvm/build-linux.sh

# Script for building the Linux kernel from git. It aims to build a kernel image
|
|
# that is suitable for running in a virtual machine and is aimed to used for
|
|
# testing.

# Usage: build-linux.sh [REPO-URL] [BRANCH|TAG] [OUTPUT-FILE] [...CONFIGS]
|

# Where [..CONFIGS] can be any number of configuration options, e.g.
|
|
# --enable CONFIG_DRM_VKMS
