I noticed that userboot doesn't contain inb()/outb() bindings:
inb (port -- char)
Reads a byte from a port.
outb (port char --)
Writes a byte to a port.
Yet, manual page for bhyveload(8) claims:
bhyveload is based on loader(8) and will present an interface identical
to the FreeBSD loader on the user's terminal.
Is there any interest in adding this functionality?
It won't work for bhyveload/userboot - the VM isn't actually running
at that point so there's nowhere for the commands to go.
I also don't think these commands are supported on non-x86 loaders
either, so it could be claimed an issue with the man page :) I can put
some text in the bhyveload man page to indicate that not all x86
commands are supported (smap, pnpscan etc).
Were you looking at using inb/outb for anything in particular ?
