[PATCH 00/11] (v6) virtio: console: Fixes, new way of discovering ports
Hello,
This series reworks the ABI to allow port discovery (only) via the
control queue and enable multiport again.
In addition, it adds support for non-blocking write() support, which
means no spinning. This works fine with the recent patches that are on
qemu-devel.
Also included is removal of hvc_remove() as removing one such console
port causes other console ports (registered with hvc) to
