This patch modifies virtio-console to use virtio_config_val() instead of a 'if(virtio_has_feature()) vdev->config->get()' construct to retrieve optional values from the config space.

Hello, This series adds resize support for multiple console ports. The size for each console is stored in its structure and the host informs the guest about size changes via the VIRTIO_CONSOLE_RESIZE control message. This is easily tested by the qemu patches provided by Kusanagi Kouichi with some updates, which I will shortly send to the qemu-devel list. Please apply, Amit. Amit Shah (3):

Unfortunately there proved to be at least one bug which requires an ABI change, so we're best off not introducing multiport support until 2.6.35. While I generally left the multiport code paths intact, I really wanted to remove the ABI defines from the header, which meant some quite deep cuts.

From: Francois Diakhate <fdiakh at gmail.com> Currently early_put_chars is not used by virtio_console because it can only be used once a port has been found, at which point it's too late because it is no longer needed. This patch should fix it. Acked-by: Christian Borntraeger <borntraeger at de.ibm.com> Signed-off-by: Amit Shah <amit.shah at redhat.com> Signed-off-by: Rusty

If we're using multiport, there's no point in always creating a console port. Create the console port only if the host doesn't support multiport.

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
