[Qemu-devel] [virtio-dev] New virtio device specification

[Christian Pinto]

Hi all,

we are working on a new virtio device, namely the Signal Distribution
Module (SDM). The SDM routes inter-processor signals intra and inter QEMU
instances, using a user-defined communication channel. At the current state
the
SDM provides a local channel, for intra-QEMU signals, and a channel based on
sockets (UNIX or TCP) to exchange signals between processors in different
instances of QEMU. Each communication channel exports a common interface for
the sake of ease of extension and integration of new channels.

In addition to the virtio version, a platform device version is available as
well to be used for cases where a processor is not running Linux but another
OS/firmware that does not support virtio.

For more details you can have a look at the following link:

https://lists.gnu.org/archive/html/qemu-devel/2016-03/msg04492.html

where you can find the latest RFC patch set for the QEMU code of the virtio
SDM
device.

Kernel code is publicly accessible from:

https://git.virtualopensystems.com/dev/qemu-het-tools/tree/sdm_test_virtio_mod_v1/


I am writing to understand how to start the procedure to include this
device in
the virtio specification and get a virtio device ID assigned.


Thanks in advance for your feedback.


Best regards,

Christian

The best way is to prepare some patches against the standard doc (svn
tree here:
https://tools.oasis-open.org/version-control/browse/wsvn/virtio/):
- one patch reserving a device id
- one patch actually specifying the new device

Hello Cornelia,

thanks for this clarification. I will immediately start looking into this
and soon release the two patches.


Best,

Christian
