With updated port there's also support for CUSE, which would allow
swtpm
to be used with pass-through. The problem is that socket and CUSE
have
problems which I described in upstream issue:
https://github.com/stefanberger/swtpm/issues/820. If there are any
suggestions how to fix that fuse error, I'd like to hear them and try
and fix it.

Hello,
I was wrong. Linux CUSE is extension of FUSE while FreeBSD CUSE has
totally different implementation, so it can not be used by swtpm. As
swtpm has control and server channels, I suppose we need both. To start
both:
# swtpm socket --tpmstate dir=/tmp/mytpm1 --ctrl
type=unixio,path=/tmp/mytpm1/ctrl --tpm2 --log level=20 --server
type=unixio,path=/tmp/mytpm1/server
Now to initialize it one should run
# swtpm_ioctl --unix /tmp/mytpm1/swtpm-sock -i
If -i is replaced with --stop, swtpm is stopped. Now if I understand
correctly, init function of bhyve should do -i, deinit should do --stop.
If that's correct, I will start implementing init and for now ignore
deinit. As swtpm is BSD licenced, I think it is OK for us to reuse parts
of swtpm_ioctl code. Anyway, if I'm wrong about anything, please point
it out.
