9 This option will cause messages to be printed if free stack space
10 drops below a certain limit.

12config KPROBES
13 bool "Kprobes"
14 depends on DEBUG_KERNEL
15 help
16 Kprobes allows you to trap at almost any kernel address and
17 execute a callback function. register_kprobe() establishes
18 a probepoint and specifies the callback. Kprobes is useful
19 for kernel debugging, non-intrusive instrumentation and testing.
20 If in doubt, say "N".

22config DEBUG_STACK_USAGE
23 bool "Stack utilization instrumentation"
24 depends on DEBUG_KERNEL
25 help
26 Enables the display of the minimum amount of free stack which each
27 task has ever had available in the sysrq-T and sysrq-P debug output.

29 This option will slow down process creation somewhat.

35 Include in-kernel hooks for kernel debuggers. Unless you are
36 intending to debug the kernel, say N here.

42 Include in-kernel hooks for the xmon kernel monitor/debugger.

53config IRQSTACKS
54 bool "Use separate kernel stacks when processing interrupts"
55 help
56 If you say Y here the kernel will use separate kernel stacks
57 for handling hard and soft interrupts. This can help avoid
58 overflowing the process kernel stacks.
