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:
where you can find the latest RFC patch set for the QEMU code of the virtio SDM
Kernel code is publicly accessible from:
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.
