9 Write kernel log output directly via the hypervisor console.
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 Debug info can be large, and flags like
23 `-femit-struct-debug-baseonly' can reduce the kernel file
24 size and build time noticeably. Such flags are often
25 helpful if the main use of debug info is line number info.
