Samsung Modem

From postmarketOS

This is a technical page designed to see how to implement support for Samsung modems in postmarketOS.

Samsung modems use three abstraction layers:

  1. Kernel interface (specific to each modem)
  2. Samsung IPC modem protocol (specific to Samsung devices)
  3. Radio Interface Layer (universal)

The IPC protocol, libsamsung-ipc, has been reimplemented as free software by Replicant.

There have been patches to add libsamsung-ipc support to ofono, a potential RIL for postmarketOS, but it doesn't seem like they were merged due to licensing issues which have now been resolved. The patches have been forward-ported to the new libsamsung-ipc interfaces at
