Hidetoshi:
Here are some patches I came up with that update sbp_targ to
work with
FreeBSD 6. I added a new XPORT type for FireWire, added a
no op for
XPT_SET_TRAN_SETTINGS and coded(stolen from sbp.c) to do
"stuff". I've
added a couple of printf's for my own logging, but they are
useful for
others.
I wrote a small shell script that I'm using with my
testing(see attached
start_firewire.sh).
I've attached my kernel configuration for your review(see
attached file
BRUNO).
I've also noted a witness error in sbp_targ that looks like
a Giant failure:
