# 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 builddir resdir minutes qemu-args boot_args
|
||
|
|
#
|
||
|
|
# qemu-args defaults to "-nographic", along with arguments specifying the
|
||
|
|
# number of CPUs and other options generated from
|
||
|
|
# the underlying CPU architecture.
|
||
|
|
# boot_args defaults to value returned by the per_version_boot_params
|
||
|
|
# shell function.
|
||
|
|
#
|
||
|
|
# Anything you specify for either qemu-args or boot_args 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.
