My purpose is to modify kernel function instructions directly through
memory at runtime.
First I use "objdump -S kernel" to see the function names and their
addresses. And then I use pointers to peek into the content at certain
function address area (.text segment). However, their content is diffe
Hm, there was one bug in that script. I uploaded a fixed version. The fix was:
- printf("%d %d KTRGRAPH group:\"thread\", id:\"%s/%s tid %d\",
state:\"runq add\", attributes: prio:%d, linkedto:\"%s/%s tid %d\"\n",
cpu, timestamp, args[0]->td_proc->p_comm, args[0]->td_name,
args[0]->td_tid,
... ignore it for now; I ran some other profiling and then when I
tried schedgraph.d again, it started spitting out events for that CPU.
I'll file a PR if I see it happen more often.

Hi,
I'm having problems with Ryan's schedgraph.d script
(people.freebsd.org/~rstone/dtrace/)
It runs fine, but if a CPU core is 100% busy, I get zero scheduler
events logged from it. Said core is doing around 30,000 syscalls a
second, around 250,000 context switches and 125,000 interrupt sa

There is a problem report since July 2014 in a Perl bug tracker,
which seems to affect only FreeBSD 10.0 amd64 (regardless of a
version of Perl or usage of clang vs. gcc compiler):
