| 9 | Write kernel log output directly via the hypervisor console. |
| 10 | |
| 11 | This is useful for kernel debugging when your machine crashes very |
| 12 | early before the console code is initialized. For normal operation |
| 13 | it is not recommended because it looks ugly and doesn't cooperate |
| 14 | with klogd/syslogd. You should normally N here, |
| 15 | unless you want to debug such a crash. |

| 22 | defined in arch/tile/kernel/hvglue.S. This allows tracing |
