| #!/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-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. |
