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. 20 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. 27 28 This option will slow down process creation somewhat. 29 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. 40 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'. 48 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. 75 76endmenu 77
