6 | bool "Check for stack overflows" | ||

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

12 | config 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". | ||
21 | |||
22 | config 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. | ||
28 | |||
29 | This option will slow down process creation somewhat. | ||

32 | bool "Enable debugger hooks" | ||
33 | depends on DEBUG_KERNEL | ||
34 | help | ||
35 | Include in-kernel hooks for kernel debuggers. Unless you are | ||
36 | intending to debug the kernel, say N here. | ||

38 | config XMON | ||
39 | bool "Include xmon kernel debugger" | ||
40 | depends on DEBUGGER && !PPC_ISERIES | ||
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. | ||
44 | Make sure to enable also CONFIG_BOOTX_TEXT on Macs. Otherwise | ||
45 | nothing will appear on the screen (xmon writes directly to the | ||
46 | framebuffer memory). | ||
47 | The cmdline option 'xmon' or 'xmon=early' will drop into xmon very | ||
48 | early during boot. 'xmon=on' will just enable the xmon debugger hooks. | ||
49 | 'xmon=off' will disable the debugger hooks if CONFIG_XMON_DEFAULT is set. | ||
50 | |||
51 | config XMON_DEFAULT | ||
52 | bool "Enable xmon by default" | ||
53 | depends on XMON | ||
54 | help | ||
55 | xmon is normally disabled unless booted with 'xmon=on'. | ||
56 | Use 'xmon=off' to disable xmon init during runtime. | ||
57 | |||
58 | config IRQSTACKS | ||
59 | bool "Use separate kernel stacks when processing interrupts" | ||
60 | help | ||
61 | If you say Y here the kernel will use separate kernel stacks | ||
62 | for handling hard and soft interrupts. This can help avoid | ||
63 | overflowing the process kernel stacks. | ||
