The vmmapi library abstracts those interfaces wherever 19possible so that the bhyve userspace can remain close to upstream. 20 21The source code for the following components is present and included in 22syncs from FreeBSD, but currently disabled. See the comments in 'Makefile' 23for more details: 24 25 kernemu_dev 26 virtio-scsi 27 audio backend 28 virtio_input 29 30The draft Save/Restore functionality, added in FreeBSD commit 31483d953a86a2507355f8287c5107dc827a0ff516, has not been synced into illumos bhyve 32yet. It is not built by default in FreeBSD, so we're not interested in taking 33it until it successfully endures more in-depth testing. 34 35The stub usr/src/compat/bhyve/stdatomic.h file only includes enough glue 36to satisfy the use of <stdatomic.h> in usr/src/cmd/bhyve/rfb.c, and in 37particular assumes that atomic variables are sized as an int. If other bhyve 38pieces start using stdatomic.h, this will need enhancing. 39 40
