--- Comment #25 from Conrad Meyer <c...@freebsd.org> ---
Thanks, Eirik. Let me see if I can come up with some copy-paste incantations
to try. I'm not a dtrace expert myself. :-)
Load dtrace support: sudo kldload dtraceall
First, to see if aesni functions are being hit at all:
sudo dtrace -n 'fbt:aesni::entry { @[probefunc] = count() }'
Let it run for maybe a few seconds while there is any mild load to the GELI
disks, then hit Ctrl-C. After Ctrl-C, wait a few seconds for dtrace to print
output and exit. If the output is empty, nothing is calling into aesni.
Otherwise, you should see a listing of (aesni) function name, invocation count
pairs.
If you get anything from the earlier trace, the following one should print out
(approximately) any errors returned by aesni functions (columns are: function,
error number, count):
sudo dtrace -n 'fbt:aesni::return /arg1 > 0 && arg1 < 1000/ {
@[probefunc,arg1] = count() }'
