Alright, I know this tablet is over 10 years old and there likely isn't ANYONE maintaining it anymore. But I managed to not only get it up and running on the mainline kernel, but also got the modem functioning with internet access through NM.
The issue is that it was mostly vibe-coded (as I do not have confidence in my own ability to create a kernel-level driver), I have no idea how Nura/pmOS feels about vibe-coded contributions, but I would LOVE to contribute this modem driver so that the Nexus 7's feature set is more complete. I am working on other issues with the device on mainline right now (display works, touch is in progress, slimport isn't tested but assumed working, WiFi works properly. GNOME Mobile starts and functions fine on it as well.
If Nura allows vibe-coded contributions, I would love to contribute the driver. I am unsure how to go about doing so however. I have it currently packaged as an AKMS package to make distribution and installation easier. If allowed, how would I go about doing so?
EDIT: I guess it's more like TWO AKMS packages, one for the modem itself and the other for the EHCI HSIC which appears to have gone missing or broken in the mainline kernel for this device.
