menu "Kernel hacking"
config TRACE_IRQFLAGS_SUPPORT
bool
default y
source "lib/Kconfig.debug"
config EARLY_PRINTK
bool "Early printk" if EMBEDDED
depends on SYS_HAS_EARLY_PRINTK
default y
help
This option enables special console drivers which allow the kernel
to print messages very early in the bootup process.
This is useful for kernel debugging when your machine crashes very
early before the console code is initialized. For normal operation,
it is not recommended because it looks ugly on some machines and
doesn't cooperate with an X server. You should normally say N here,
unless you want to debug such a crash.
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 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 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
arch/mips/include/asm/debug.h for debugging macros.
If unsure, say N.
