The vmmapi library abstracts those interfaces wherever 21possible so that the bhyve userspace can remain close to upstream. 22 23The source code for the following components is present and included in 24syncs from FreeBSD, but currently disabled. See the comments in 'Makefile' 25for more details: 26 27 kernemu_dev 28 virtio-scsi 29 audio backend 30 virtio_input 31 32The draft Save/Restore functionality, added in FreeBSD commit 33483d953a86a2507355f8287c5107dc827a0ff516, has not been synced into illumos bhyve 34yet. It is not built by default in FreeBSD, so we're not interested in taking 35it until it successfully endures more in-depth testing. 36 37The stub usr/src/compat/bhyve/stdatomic.h file only includes enough glue 38to satisfy the use of <stdatomic.h> in usr/src/cmd/bhyve/rfb.c, and in 39particular assumes that atomic variables are sized as an int. If other bhyve 40pieces start using stdatomic.h, this will need enhancing. 41 42
