6    bool "Early printk" if EXPERT && DEBUG_KERNEL
7    default y
8    help
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.
16
17config DEBUG_STACKOVERFLOW
18    bool "Check for stack overflows"
19    depends on DEBUG_KERNEL
20    help
21      This option will cause messages to be printed if free stack space
22      drops below a certain limit.
23
24config DEBUG_STACK_USAGE
25    bool "Stack utilization instrumentation"
26    depends on DEBUG_KERNEL
27    help
28      Enables the display of the minimum amount of free stack which each
29      task has ever had available in the sysrq-T and sysrq-P debug output.
30
31      This option will slow down process creation somewhat.

33config DEBUG_EXTRA_FLAGS
34    string "Additional compiler arguments when building with '-g'"
35    depends on DEBUG_INFO
36    default ""
37    help
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.
