6 bool "Check for stack overflows"
7 depends on DEBUG_KERNEL
11 depends on DEBUG_KERNEL
13 Kprobes allows you to trap at almost any kernel address and
14 execute a callback function. register_kprobe() establishes
15 a probepoint and specifies the callback. Kprobes is useful
16 for kernel debugging, non-intrusive instrumentation and testing.
19 config DEBUG_STACK_USAGE
20 bool "Stack utilization instrumentation"
21 depends on DEBUG_KERNEL
23 Enables the display of the minimum amount of free stack which each
24 task has ever had available in the sysrq-T and sysrq-P debug output.
26 This option will slow down process creation somewhat.
29 bool "Enable debugger hooks"
30 depends on DEBUG_KERNEL
32 Include in-kernel hooks for kernel debuggers. Unless you are
33 intending to debug the kernel, say N here.
36 bool "Include xmon kernel debugger"
37 depends on DEBUGGER && !PPC_ISERIES
39 Include in-kernel hooks for the xmon kernel monitor/debugger.
40 Unless you are intending to debug the kernel, say N here.
43 bool "Enable xmon by default"
47 bool "Include PPCDBG realtime debugging"
48 depends on DEBUG_KERNEL
51 bool "Use separate kernel stacks when processing interrupts"
53 If you say Y here the kernel will use separate kernel stacks
54 for handling hard and soft interrupts. This can help avoid
55 overflowing the process kernel stacks.
