6 | # Execute this in the source tree. Do not run it as a background task | |
7 | # because qemu does not seem to like that much. | |

11 | # qemu-args defaults to "" -- you will want "-nographic" if running headless. | |
4a261dbc | 12 | # boot_args defaults to "root=/dev/sda noapic selinux=0 console=ttyS0" |

15 | # "rcutorture.rcutorture_runnable=1" | |

4a261dbc | 17 | # Anything you specify for either qemu-args or boot_args is appended to |
c87b9c60 PM |
18 | # the default values. The "-smp" value is deduced from the contents of |
19 | # the config fragment. | |

21 | # More sophisticated argument parsing is clearly needed. | |
