Say Y here if you are compiling the kernel on a different
|
|
architecture than the one it is intended to run on. This is just a
|
|
convenience option which will select the appropriate value for
|
|
the CROSS_COMPILE make variable which otherwise has to be passed on
|
|
the command line from mips-linux-, mipsel-linux-, mips64-linux- and
|
|
mips64el-linux- as appropriate for a particular kernel configuration.
|
|
You will have to pass the value for CROSS_COMPILE manually if the
|
|
name prefix for your tools is different.

help
|
|
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.

config DEBUG_STACK_USAGE

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

This option will slow down process creation somewhat.

|
help
|
|
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.
|
|
|
|
config GDB_CONSOLE

bool "Console output to GDB"
|
|
depends on KGDB
|
|
help
|
|
If you are using GDB for remote debugging over a serial port and
|
|
would like kernel messages to be formatted into GDB $O packets so
|
|
that GDB prints them as program output, say 'Y'.

config RUNTIME_DEBUG

bool "Enable run-time debugging"

depends on DEBUG_KERNEL
|
|
help
|
|
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 unsure, say N.

config MIPS_UNCACHED

bool "Run uncached"
|

depends on DEBUG_KERNEL && !SMP && !SGI_IP27
|
|
help
|
|
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.
