#!/bin/bash
#
# 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: sh kvm-test-1-rcu.sh config builddir resdir minutes qemu-args bootargs
#
# qemu-args defaults to "" -- you will want "-nographic" if running headless.
# bootargs defaults to "root=/dev/sda noapic selinux=0 console=ttyS0"
# "initcall_debug debug rcutorture.stat_interval=15"
# "rcutorture.shutdown_secs=$((minutes * 60))"
# "rcutorture.rcutorture_runnable=1"
#
# Anything you specify for either qemu-args or bootargs 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.
