# SPDX-License-Identifier: GPL-2.0+
#
# Run a kvm-based test of the specified tree on the specified configs.
# Fully automated run and error checking, no graphics console.
#
# Execute this in the source tree.  Do not run it as a background task
# because qemu does not seem to like that much.
#
# Usage: kvm-test-1-run.sh config resdir seconds qemu-args boot_args_in
#
# qemu-args defaults to "-enable-kvm -display none -no-reboot", along
#			with arguments specifying the number of CPUs
#			and other options generated from the underlying
#			CPU architecture.
# boot_args_in defaults to value returned by the per_version_boot_params
#			shell function.
#
# Anything you specify for either qemu-args or boot_args_in is appended to
# the default values.  The "-smp" value is deduced from the contents of
# the config fragment.
#
# More sophisticated argument parsing is clearly needed.
