16The source code for the following components is present and included in
17syncs from FreeBSD, but currently disabled. See the comments in 'Makefile'
18for more details:

21	virtio-scsi
22	audio backend

25The draft Save/Restore functionality, added in FreeBSD commit
26483d953a86a2507355f8287c5107dc827a0ff516, has not been synced into illumos bhyve
27yet.  It is not built by default in FreeBSD, so we're not interested in taking
28it until it successfully endures more in-depth testing.

30The stub usr/src/compat/bhyve/stdatomic.h file only includes enough glue
31to satisfy the use of <stdatomic.h> in usr/src/cmd/bhyve/rfb.c, and in
32particular assumes that atomic variables are sized as an int. If other bhyve
33pieces start using stdatomic.h, this will need enhancing.
