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: sh kvm-test-1-rcu.sh config builddir resdir minutes qemu-args bootargs | ||
10 | # | ||
11 | # qemu-args defaults to "" -- you will want "-nographic" if running headless. | ||
12 | # bootargs defaults to "root=/dev/sda noapic selinux=0 console=ttyS0" | ||
13 | # "initcall_debug debug rcutorture.stat_interval=15" | ||
14 | # "rcutorture.shutdown_secs=$((minutes * 60))" | ||
15 | # "rcutorture.rcutorture_runnable=1" | ||
16 | # | ||
17 | # Anything you specify for either qemu-args or bootargs is appended to | ||
18 | # the default values. The "-smp" value is deduced from the contents of | ||
19 | # the config fragment. | ||
20 | # | ||
