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

| 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". | |

| 22 | config DEBUG_STACK_USAGE | |

| 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. | |

| 34 | help | |
| 35 | Include in-kernel hooks for kernel debuggers. Unless you are | |
| 36 | intending to debug the kernel, say N here. | |

| 41 | help | |
| 42 | Include in-kernel hooks for the xmon kernel monitor/debugger. | |
| 43 | Unless you are intending to debug the kernel, say N here. | |

| 53 | config 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. | |
