config DEBUG_STACKOVERFLOW
bool "Check for stack overflows"
depends on DEBUG_KERNEL
config KPROBES
bool "Kprobes"
depends on DEBUG_KERNEL
help
Kprobes allows you to trap at almost any kernel address and
execute a callback function. register_kprobe() establishes
a probepoint and specifies the callback. Kprobes is useful
for kernel debugging, non-intrusive instrumentation and testing.
If in doubt, say "N".
config DEBUG_STACK_USAGE
bool "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 DEBUGGER
bool "Enable debugger hooks"
depends on DEBUG_KERNEL
help
Include in-kernel hooks for kernel debuggers. Unless you are
intending to debug the kernel, say N here.
config XMON
bool "Include xmon kernel debugger"
depends on DEBUGGER && !PPC_ISERIES
help
Include in-kernel hooks for the xmon kernel monitor/debugger.
Unless you are intending to debug the kernel, say N here.
config XMON_DEFAULT
bool "Enable xmon by default"
depends on XMON
config PPCDBG
bool "Include PPCDBG realtime debugging"
depends on DEBUG_KERNEL
config IRQSTACKS
bool "Use separate kernel stacks when processing interrupts"
help
If you say Y here the kernel will use separate kernel stacks
for handling hard and soft interrupts. This can help avoid
overflowing the process kernel stacks.
