my guess is that a fully free software firmware for the pinephone modem if in the works, but I could very well be wrong here

@iansutter @Bobo_PK @PINE64 @postmarketOS It can't be fully open because the firmware for the DSP is closed, but this brings it slightly more to the open side.

@martijnbraam @Bobo_PK @PINE64 @postmarketOS

ah ok.

still cool either way though.

@Bobo_PK A port of Doom 🤣 @PINE64 @postmarketOS

@feld @PINE64 @postmarketOS Shh. We need to see how many instances of Linux can simultaneously run on the Pine Phone

@feld @PINE64 @postmarketOS The mobile network communication part already runs on a DSP core inside the modem, this is linux 5.10 running on the application processor in the modem that's responsible for passing along the data and providing the configuration interface. Normally this runs some 3.x kernel.

@martijnbraam @PINE64 @postmarketOS that still seems like a huge unnecessary attack surface to use Linux on that application processor

@martijnbraam @feld @PINE64 @postmarketOS Amazing milestone! It's the first device I know where this was accomplished.

We better don't want to know what version of Linux runs on a typical Android device (provided its modem runs on a separate chip like in the #pinephone).

@kuleszdl @feld @PINE64 @postmarketOS well most devices don't have a seperate modem. So when the phone is mainlined in postmarketOS they're at the same point as this.

@martijnbraam @feld @PINE64 @postmarketOS Yes, but only regarding the Linux version. There are good arguments regarding security why the modem should be isolated just like it is done in the #pinephone, and in the early Android days many devices did have this separation in place.

Of course, on the other hand, having separate chips often comes with the trade-off of less power efficiency and higher costs. But I really hope the next #pinephone will keep these things separated.

@martijnbraam @kuleszdl @feld @PINE64 @postmarketOS There has been some research at https://osmocom.org/projects/quectel-modems/wiki. And it's not only about Android, iPhone 5's modem and some USB-Modems also use Linux.

@martijnbraam @feld @PINE64 @postmarketOS How near is that 5.10 kernel to mainline?

@Alexmitter @feld @PINE64 @postmarketOS it's 17 commits ahead, of 5.10, it's not huge.

@martijnbraam @feld @PINE64 @postmarketOS Where is the repo?

@Alexmitter @feld @PINE64 @postmarketOS ah it's at 19 commits currently: https://github.com/SoMainline/linux/tree/konrad/pinemodem

@martijnbraam thank you

@martijnbraam @feld @PINE64 @postmarketOS Do I see it right? Isn't it based on the 5.11 rc1 state, not 5.10?

@Alexmitter @feld @PINE64 @postmarketOS yeah it got rebased

@wisemonkey @PINE64 @postmarketOS IIRC, the #Librem5 uses m.2 for their modems. The Quectel EG-25G in the #PinePhone appears to big to fit on such a card:

@linmob @PINE64 @postmarketOS thanks, so at least #PinePhone can make use of this, as long as it gets in mobile it's good news.

@JJS_10 @PINE64 @postmarketOS I had the exact same question. 😆
