The bhyve(8) exit status indicates how the VM was terminated:
0 rebooted
1 powered off
2 halted
3 triple fault
The problem is when we have wrappers around bhyve that parses the exit
error code and gets an exit(1) for an error but interprets it as "powered off".
So to mitigate this issue and makes it less error prone for third part
applications, I have added a new exit code 4 that is "exited due to an error".
For now the bhyve(8) exit status are:
0 rebooted
1 powered off
2 halted
3 triple fault
4 exited due to an error

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.
timer support. This should be enough for the emulation of
h/w periodic timers (and no more) e.g. some of the 8254's
more esoteric modes that happen to be used by non-FreeBSD o/s's.
