The reaction of kvm-recheck.sh is obscure at best, and easy to miss completely. This commit therefore prints "BUG: Build failed" in the summary at the end of a run. This commit also adds the line of dashes in cases where performance info is not available, and also avoids printing nonsense diagnostics in cases where some of the normal test output is not available. In addition, this commit saves off the .config file even when the build fails. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>

# 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-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.
