Modified files:
sys/conf options
sys/sys ktr.h
sys/kern kern_ktr.c
Log:
- Remove much of the inlining of the KTR tracepoints into a ktr_tracepoint()
function declared in kern_ktr.c. The only inline checks left are the
checks that compare KTR_COMPILE with the supplied mask and thus should
be optimized away into either nothing or a direct call to ktr_tracepoint().
- Move several KTR-related options to opt_ktr.h now that they are only
needed by kern_ktr.c and not by ktr.h.
- Add in the ktr_verbose functionality if KTR_EXTEND is turned on. If the
global variable 'ktr_verbose' is non-zero, then KTR messages will be
dumped to the console. This variable can be set by either kernel code
or via the 'debug.ktr_verbose' sysctl. It defaults to off unless the
KTR_VERBOSE kernel option is specified in which case it defaults to on.
This can be useful when the machine locks up spinning in a loop with
interrupts disabled as you might be able to see what it is doing when it
locks up.
