| 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. | ||

| 38 | Debug info can be large, and flags like | ||
| 39 | `-femit-struct-debug-baseonly' can reduce the kernel file | ||
| 40 | size and build time noticeably. Such flags are often | ||
| 41 | helpful if the main use of debug info is line number info. | ||
