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".

Make sure to enable also CONFIG_BOOTX_TEXT on Macs. Otherwise

|
|
|
|
nothing will appear on the screen (xmon writes directly to the
|
|
|
|
|
framebuffer memory).
|
|
|
|
|
The cmdline option 'xmon' or 'xmon=early' will drop into xmon very
|
|
|
|
|
early during boot. 'xmon=on' will just enable the xmon debugger hooks.
|
|
|
|
|
'xmon=off' will disable the debugger hooks if CONFIG_XMON_DEFAULT is set.

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.
