With modern high-speed 4G and 5G modems, it is more and more common to connect the modem over the PCIe bus instead of USB bus. PCIe offers higher speed, lower latency and lower power consumption than USB equivalent, making it perfectly suitable for 5G high speed requirements (up to 20Gbps). To support PCIe modems, we first had to enable all kernel modules related to the Qualcomm Modem-Host Interface (MHI), which was done in the eve-kernel repo, e.g.: lf-edge/eve-kernel#91 Next, some improvements were necessary in the mmagent to support referencing modems by the PCI address (instead of USB address). This, together with a documentation update, is done in this commit. Signed-off-by: Milan Lenco <milan@zededa.com> (cherry picked from commit 923acb5)

If the user does not select a specific SIM slot, EVE will utilize whichever SIM slot is already designated as primary (e.g., by the device manufacturer). However, there is one exception: if the primary SIM is an eSIM (virtual embedded SIM), EVE will default to using the first physical slot instead, as eSIM is not supported. EVE will attempt to connect (and fail) with the eSIM only if the user explicitly selects the eSIM slot. Signed-off-by: Milan Lenco <milan@zededa.com> (cherry picked from commit a7d23ef)

Without cellular configuration (APN, etc.), any attempt to connect through wwan interfaces will always fail. Signed-off-by: Milan Lenco <milan@zededa.com> (cherry picked from commit 3a20819)
I have seen cases where modem would not report SIM card type (the returned value was not specified), even though the (physical) SIM card was inserted. If SIM card type is not known, we can instead determine the card presence based on the ICCID number availability. Moreover, when ModemManager is unable to recognize the SIM card type, EVE would report the type as SimTypePhysical. This is clearly incorrect, SimTypeUnspecified should be reported instead.

Instead the password should be masked and replaced with e.g. asterisks. Signed-off-by: Milan Lenco <milan@zededa.com> (cherry picked from commit 0483f48)

Given the test failures due to infra issues we need to make sure this gets tested manually. We have another set of backports so can do that with multiple PRs added to 12.0 |
