6 bool "Are you using a crosscompiler"
8 Say Y here if you are compiling the kernel on a different
9 architecture than the one it is intended to run on. This is just a
10 convenience option which will select the appropriate value for
11 the CROSS_COMPILE make variable which otherwise has to be passed on
12 the command line from mips-linux-, mipsel-linux-, mips64-linux- and
13 mips64el-linux- as appropriate for a particular kernel configuration.
14 You will have to pass the value for CROSS_COMPILE manually if the
15 name prefix for your tools is different.
18 string "Default kernel command string"
21 On some platforms, there is currently no way for the boot loader to
22 pass arguments to the kernel. For these platforms, you can supply
23 some command-line options at build time by entering them here. In
24 other cases you can specify kernel args so that you don't have
25 to set them up in board prom initialization routines.
27 config DEBUG_STACK_USAGE
28 bool "Enable stack utilization instrumentation"
29 depends on DEBUG_KERNEL
31 Enables the display of the minimum amount of free stack which each
32 task has ever had available in the sysrq-T and sysrq-P debug output.
34 This option will slow down process creation somewhat.
37 bool "Remote GDB kernel debugging"
38 depends on DEBUG_KERNEL
41 If you say Y here, it will be possible to remotely debug the MIPS
42 kernel using gdb. This enlarges your kernel image disk size by
43 several megabytes and requires a machine with more than 16 MB,
44 better 32 MB RAM to avoid excessive linking time. This is only
45 useful for kernel hackers. If unsure, say N.
48 bool "Console output to GDB"
51 If you are using GDB for remote debugging over a serial port and
52 would like kernel messages to be formatted into GDB $O packets so
53 that GDB prints them as program output, say 'Y'.
56 bool "Corelis Debugger"
57 depends on SIBYTE_SB1xxx_SOC
60 Select compile flags that produce code that can be processed by the
61 Corelis mksym utility and UDB Emulator.
64 bool "Enable run-time debugging"
65 depends on DEBUG_KERNEL
67 If you say Y here, some debugging macros will do run-time checking.
68 If you say N here, those macros will mostly turn to no-ops. See
69 include/asm-mips/debug.h for debuging macros.
74 depends on DEBUG_KERNEL && !SMP && !SGI_IP27
76 If you say Y here there kernel will disable all CPU caches. This will
77 reduce the system's performance dramatically but can help finding
78 otherwise hard to track bugs. It can also useful if you're doing
79 hardware debugging with a logic analyzer and need to see all traffic
