5config CROSSCOMPILE
6 bool "Are you using a crosscompiler"
7 help
8 Say Y here if you are compiling the kernel on a different
9 architecture than the one it is intended to run on.
10
11config CMDLINE
12 string "Default kernel command string"
13 default ""
14 help
15 On some platforms, there is currently no way for the boot loader to
16 pass arguments to the kernel. For these platforms, you can supply
17 some command-line options at build time by entering them here. In
18 other cases you can specify kernel args so that you don't have
19 to set them up in board prom initialization routines.

21config DEBUG_STACK_USAGE
22 bool "Enable stack utilization instrumentation"
23 depends on DEBUG_KERNEL
24 help
25 Enables the display of the minimum amount of free stack which each
26 task has ever had available in the sysrq-T and sysrq-P debug output.

28 This option will slow down process creation somewhat.

30config KGDB
31 bool "Remote GDB kernel debugging"
32 depends on DEBUG_KERNEL
33 select DEBUG_INFO
34 help
35 If you say Y here, it will be possible to remotely debug the MIPS
36 kernel using gdb. This enlarges your kernel image disk size by
37 several megabytes and requires a machine with more than 16 MB,
38 better 32 MB RAM to avoid excessive linking time. This is only
39 useful for kernel hackers. If unsure, say N.

41config GDB_CONSOLE
42 bool "Console output to GDB"
43 depends on KGDB
44 help
45 If you are using GDB for remote debugging over a serial port and
46 would like kernel messages to be formatted into GDB $O packets so
47 that GDB prints them as program output, say 'Y'.

49config SB1XXX_CORELIS
50 bool "Corelis Debugger"
51 depends on SIBYTE_SB1xxx_SOC
52 select DEBUG_INFO
53 help
54 Select compile flags that produce code that can be processed by the
55 Corelis mksym utility and UDB Emulator.
56
57config RUNTIME_DEBUG
58 bool "Enable run-time debugging"
59 depends on DEBUG_KERNEL
60 help
61 If you say Y here, some debugging macros will do run-time checking.
62 If you say N here, those macros will mostly turn to no-ops. See
63 include/asm-mips/debug.h for debuging macros.
64 If unsure, say N.
65
66config MIPS_UNCACHED
67 bool "Run uncached"
68 depends on DEBUG_KERNEL && !SMP && !SGI_IP27
69 help
70 If you say Y here there kernel will disable all CPU caches. This will
71 reduce the system's performance dramatically but can help finding
72 otherwise hard to track bugs. It can also useful if you're doing
73 hardware debugging with a logic analyzer and need to see all traffic
74 on the bus.
