   1 #!/bin/bash
   2 #
   3 # Run a kvm-based test of the specified tree on the specified configs.
   4 # Fully automated run and error checking, no graphics console.
   5 #
   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.
   8 #
   9 # Usage: kvm-test-1-run.sh config builddir resdir minutes qemu-args boot_args
  10 #
  11 # qemu-args defaults to "-enable-kvm -soundhw pcspk -nographic", along with
  12 #                       arguments specifying the number of CPUs and other
  13 #                       options generated from the underlying CPU architecture.
  14 # boot_args defaults to value returned by the per_version_boot_params
  15 #                       shell function.
  16 #
  17 # Anything you specify for either qemu-args or boot_args is appended to
  18 # the default values.  The "-smp" value is deduced from the contents of
  19 # the config fragment.
  20 #
  21 # More sophisticated argument parsing is clearly needed.
