    Subject[PATCH v9 0/1] virtio-console: Support for generic ports and multiple consoles
    Date
    Hello all,

    Here is a new iteration of the patch series that implements a
    transport for guest and host communications.

    I've tested for compatibility (old qemu & new kernel, new qemu & old
    kernel, new qemu & new kernel) and it all works fine. To maintain
    backward compatibility, the first port to be spawned (port at id 0) is
    to be a console port, to be bound to hvc. This keeps new host, old
    guest happy.

    A testsuite is put up at the following site that has an interactive
    test program that can be run in the guest. It also has an automated
    test suite that tests the major functionalities presented here:

    http://fedorapeople.org/gitweb?p=amitshah/public_git/test-virtserial.git

    This version passes all the automated tests there.

    Christian has tested the console functionality on s390.

    v9:
    - Add debugfs files for each port to expose some port-specific information for
    easier debugging
    - Port hotplug fix
    - Disallow opening of console ports (open(/dev/vcon0) should fail)
    - A couple of other minor fixes.

    Please review and apply,
    Amit
