virtio: add full three-clause BSD text to headers.

2011-05-30T01:44:14+00:00

It's unclear to me if it's important, but it's obviously causing my technical colleages some headaches and I'd hate such imprecision to slow virtio adoption. I've emailed this to all non-trivial contributors for approval, too.

virtio: console: Use a control message to add ports

2010-05-19T12:45:49+00:00

Instead of the host and guest independently enumerating ports, switch to a control message to add ports where the host supplies the port number so there's no ambiguity or a possibility of a race between the host and the guest port numbers. We now no longer need the 'nr_ports' config value. Since no kernel has been released with the MULTIPORT changes yet, we have a chance to fiddle with the config space without adding compatibility features. This is beneficial for management software, which would now be able to instantiate ports at known locations and avoid problems that arise with implicit numbering in the host and the guest. This removes the 'guessing game' part of it, and management software can now actually indicate which id to spawn a particular port on. Signed-off-by: Amit Shah Signed-off-by: Rusty Russell

virtio: console: Let host know of port or device add failures

2010-05-19T12:45:47+00:00

The host may want to know and let management apps notify of port or device add failures. Send a control message saying the device or port is not ready in this case. Signed-off-by: Amit Shah Signed-off-by: Rusty Russell

virtio: Revert "virtio: disable multiport console support."

2010-05-19T12:45:46+00:00

This reverts commit b7a413015d2986edf020fba765c906cc9cbcbfc9. Multiport support was disabled for 2.6.34 because we wanted to introduce a new ABI and since we didn't have any released kernel with the older ABI and were out of the merge window, it didn't make sense keeping the older ABI around. Now we revert the patch disabling multiport and rework the ABI in the following patches. Signed-off-by: Amit Shah Signed-off-by: Rusty Russell

virtio: disable multiport console support.

2010-04-08T00:16:19+00:00

Move MULTIPORT feature and related config changes out of exported headers, and disable the feature at runtime. At this point, it seems less risky to keep code around until we can enable it than rip it out completely. Signed-off-by: Michael S. Tsirkin Signed-off-by: Rusty Russell

virtio: console: Add ability to hot-unplug ports

2010-02-24T03:53:00+00:00

Remove port data; deregister from the hvc core if it's a console port. Signed-off-by: Amit Shah Signed-off-by: Rusty Russell

virtio: console: Register with sysfs and create a 'name' attribute for ports

2010-02-24T03:52:56+00:00

The host can set a name for ports so that they're easily discoverable instead of going by the /dev/vportNpn naming. This attribute will be placed in /sys/class/virtio-ports/vportNpn/name. udev scripts can then create symlinks to the port using the name. Signed-off-by: Amit Shah Signed-off-by: Rusty Russell

virtio: console: Add file operations to ports for open/read/write/poll

2010-02-24T03:52:54+00:00

Allow guest userspace applications to open, read from, write to, poll the ports via the char dev interface. When a port gets opened, a notification is sent to the host via a control message indicating a connection has been established. Similarly, on closing of the port, a notification is sent indicating disconnection. Signed-off-by: Amit Shah Signed-off-by: Rusty Russell
