(Note I'm new to DTrace, so this may be ignorance on my part)
I have re-built a stock 8.2 kernel and enabled dtrace as per the
handbook (including WITH_CTF=1) and have built a kld also using
WITH_CTF=1. When I run the following
dtrace -n"bus_release_resource:entry { stack(); }"
the output looks like
...
0 33759 bus_release_resource:entry
0xffffffff813db04e
0xffffffff813db091
kernel`device_detach+0x84
kernel`driver_module_handler+0x37c
kernel`module_unload+0x49
kernel`linker_file_unload+0x178
kernel`kern_kldunload+0x117
kernel`syscallenter+0x23d
kernel`syscall+0x4b
kernel`0xffffffff808c5572
where the 0xffffffff813dbXXX addresses correspond to my kld. But I was
expecting to see symbolic names instead of addresses. Is there
something else I need to do to add the kld's symbols to the system?
TIA.
