Jan Altenberg3e7f9b822007-01-25 20:46:14 +010013 On some platforms, there is currently no way for the boot loader to
14 pass arguments to the kernel. For these platforms, you can supply
15 some command-line options at build time by entering them here. In
16 other cases you can specify kernel args so that you don't have

23 Enables the display of the minimum amount of free stack which each
24 task has ever had available in the sysrq-T and sysrq-P debug output.

26 This option will slow down process creation somewhat.

32 This option enables Enable additional debug checks before going into
33 CPU idle loop. For details on these checks, see
34 arch/mips/kernel/smtc.c. This debugging option result in significant
35 overhead so should be disabled in production kernels.

41 help
42 If you say Y here, it will be possible to remotely debug the MIPS
43 kernel using gdb. This enlarges your kernel image disk size by
44 several megabytes and requires a machine with more than 16 MB,
45 better 32 MB RAM to avoid excessive linking time. This is only
46 useful for kernel hackers. If unsure, say N.

71 If you say Y here, some debugging macros will do run-time checking.
72 If you say N here, those macros will mostly turn to no-ops. See
73 include/asm-mips/debug.h for debuging macros.
74 If unsure, say N.
