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

22 | Provide wrapper functions for the hypervisor ABI calls | |
23 | defined in arch/tile/kernel/hvglue.S. This allows tracing | |
24 | mechanisms, etc., to have visibility into those calls. | |
