Hi Chetan,
at the risk of having missed this being answered already:
How close is the older xmm7360 to the now supported xmm7560 in mainline?
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?
Thanks,
Jan

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.

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.
Thanks,
Jan

Hi Jan,
What is the context of this request ?
FYI, the driver upstreamed is for M.2 7560.

Chetan

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.

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