menu "Kernel hacking" config TRACE_IRQFLAGS_SUPPORT bool default y source "lib/Kconfig.debug" config CROSSCOMPILE bool "Are you using a crosscompiler" help 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. config CMDLINE string "Default kernel command string" default "" 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 bool "Enable stack utilization instrumentation" depends on DEBUG_KERNEL help 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. config CONFIG_SMTC_IDLE_HOOK_DEBUG bool "Enable additional debug checks before going into CPU idle loop" depends on DEBUG_KERNEL && MIPS_MT_SMTC help This option enables Enable additional debug checks before going into CPU idle loop. For details on these checks, see arch/mips/kernel/smtc.c. This debugging option result in significant overhead so should be disabled in production kernels. config KGDB bool "Remote GDB kernel debugging" depends on DEBUG_KERNEL && SYS_SUPPORTS_KGDB select DEBUG_INFO 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 SYS_SUPPORTS_KGDB bool 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 SB1XXX_CORELIS bool "Corelis Debugger" depends on SIBYTE_SB1xxx_SOC select DEBUG_INFO help Select compile flags that produce code that can be processed by the Corelis mksym utility and UDB Emulator. 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. endmenu
