3 config TRACE_IRQFLAGS_SUPPORT
7 source "lib/Kconfig.debug"
10 bool "Are you using a crosscompiler"
12 Say Y here if you are compiling the kernel on a different
13 architecture than the one it is intended to run on. This is just a
14 convenience option which will select the appropriate value for
15 the CROSS_COMPILE make variable which otherwise has to be passed on
16 the command line from mips-linux-, mipsel-linux-, mips64-linux- and
17 mips64el-linux- as appropriate for a particular kernel configuration.
18 You will have to pass the value for CROSS_COMPILE manually if the
19 name prefix for your tools is different.
22 string "Default kernel command string"
25 On some platforms, there is currently no way for the boot loader to
26 pass arguments to the kernel. For these platforms, you can supply
27 some command-line options at build time by entering them here. In
28 other cases you can specify kernel args so that you don't have
29 to set them up in board prom initialization routines.
31 config DEBUG_STACK_USAGE
32 bool "Enable stack utilization instrumentation"
33 depends on DEBUG_KERNEL
35 Enables the display of the minimum amount of free stack which each
36 task has ever had available in the sysrq-T and sysrq-P debug output.
38 This option will slow down process creation somewhat.
40 config SMTC_IDLE_HOOK_DEBUG
41 bool "Enable additional debug checks before going into CPU idle loop"
42 depends on DEBUG_KERNEL && MIPS_MT_SMTC
44 This option enables Enable additional debug checks before going into
45 CPU idle loop. For details on these checks, see
46 arch/mips/kernel/smtc.c. This debugging option result in significant
47 overhead so should be disabled in production kernels.
50 bool "Remote GDB kernel debugging"
51 depends on DEBUG_KERNEL && SYS_SUPPORTS_KGDB
54 If you say Y here, it will be possible to remotely debug the MIPS
55 kernel using gdb. This enlarges your kernel image disk size by
56 several megabytes and requires a machine with more than 16 MB,
57 better 32 MB RAM to avoid excessive linking time. This is only
58 useful for kernel hackers. If unsure, say N.
60 config SYS_SUPPORTS_KGDB
64 bool "Console output to GDB"
67 If you are using GDB for remote debugging over a serial port and
68 would like kernel messages to be formatted into GDB $O packets so
69 that GDB prints them as program output, say 'Y'.
72 bool "Corelis Debugger"
73 depends on SIBYTE_SB1xxx_SOC
76 Select compile flags that produce code that can be processed by the
77 Corelis mksym utility and UDB Emulator.
80 bool "Enable run-time debugging"
81 depends on DEBUG_KERNEL
83 If you say Y here, some debugging macros will do run-time checking.
84 If you say N here, those macros will mostly turn to no-ops. See
85 include/asm-mips/debug.h for debuging macros.
90 depends on DEBUG_KERNEL && !SMP && !SGI_IP27
92 If you say Y here there kernel will disable all CPU caches. This will
93 reduce the system's performance dramatically but can help finding
94 otherwise hard to track bugs. It can also useful if you're doing
95 hardware debugging with a logic analyzer and need to see all traffic
