virtio device ID

Dear OASIS Team,

 

I am currently working on a guest sound card driver based on VIRTIO (Linux guest ->ALSA driver).

The virtio spec (Appendix B3) suggests to use ‘65535 and backward’ for experimental drivers – but when looking deeper at the spec /probing it seems that device ID’s are limited to 63.

So currently I use 63 (PCI Device ID 0x1040+63d ) to avoid conflicts with upcoming new ID’s.

 

The host implementation will probably not be open source but nevertheless I feel that reserving at least an own unique ID for ‘sound transport’ or ‘sound card’ would be helpful.

 

Is there a chance to get an ID for such device type reserved?

 

 

Thank You,

 

 

Best regards
