There is that reverse engineered PCI driver [1] with non-standard userland interface, and it would obviously be great to benefit from common infrastructure and specifically the modem-manager compatible interface. Is this realistic to achieve for the 7360, or is that hardware or its firmware too different?

The context is that there are many folks out there (me included - Lenovo P52) with devices that have the xmm-7360 built-in, can't switch it to USB mode (prevented by OEM), and currently require [1]. That kind of works but is not really the final solution. So I also kicked off [2] there. > > FYI, the driver upstreamed is for M.2 7560. I know. I'm not an expert on the details, but reading the overall architectures of the IOSM and what has been reverse-engineered for the 7360, there seem to be some similarities. So, maybe you can explain to the community if that is a reasonable path to upstream 7360 support, or if at least the pattern of the 7560 could/should be transferred to the 7360 driver.

It also seems the 7560 card doesn't show up in my X13 AMD (Gen 1) at all - so even if I'd "upgrade" that card, I couldn't use it. >I know.

Very curious about this as well - they might share some code at lest, if not even the driver?
