freebsd-dev/usr.sbin/bhyve
History
Mark Johnston d6ef759e5d Use separate descriptors in bhyve's stdio uart backend. 
bhyve was previously using stdin for both reading and writing to the
console, which made it difficult to redirect console output.  Use
stdin for reading and stdout for writing.  This makes it easier to use
bhyve as a backend for syzkaller.

As a side effect, the change fixes a minor bug which would cause bhyve
to fail with ENOTCAPABLE if configured to use nmdm for com1 and stdio
for com2.

bhyveload already uses separate descriptors, as does the bvmcons driver.
