This is QMI-over-MHI. Why do we need a different QMI-over-X for every X? If you say there are already chardev interfaces to configure WWAN why not provide one of those? > It's not networking data plane. It's WWAN device configuration. Ack. Not that network config doesn't fall under networking, but eh. I wonder - did DaveM ever ack this, or was it just out of his sight enough, behind the cdev, to never trigger a nack? > There are no current kernel APIs for this, and I really don't think we > want there to be.

I don't think anyone in the development community or among users is particularly happy about the situation. Which makes it rather self evident why there is so much apprehension about this patch set. It's going to be a user space channel for everything Qualcomm - AI accelerator etc. Widening the WWAN status quo to more device types.
