On some platforms, there is currently no way for the boot loader to
|
||
|
|
pass arguments to the kernel. For these platforms, you can supply
|
||
|
|
some command-line options at build time by entering them here. In
|
||
|
|
other cases you can specify kernel args so that you don't have
|
||
|
|
to set them up in board prom initialization routines.

This option will slow down process creation somewhat.

If you say Y here, it will be possible to remotely debug the MIPS
|

|
|
kernel using gdb. This enlarges your kernel image disk size by
|
||
|
|
several megabytes and requires a machine with more than 16 MB,
|

|
|
better 32 MB RAM to avoid excessive linking time. This is only

useful for kernel hackers. If unsure, say N.

If you say Y here, some debugging macros will do run-time checking.

If you say N here, those macros will mostly turn to no-ops. See

include/asm-mips/debug.h for debuging macros.

If you say Y here there kernel will disable all CPU caches. This will
|
||
|
|
reduce the system's performance dramatically but can help finding
|

|
|
otherwise hard to track bugs. It can also useful if you're doing
|

hardware debugging with a logic analyzer and need to see all traffic
|
||
|
|
on the bus.
