Instead of warning about various unimportant things failing that don't
affect functionality, just print the logs in debug level and go on.
E.g. this warning can be completely skipped:
<wrn> [modem0] couldn't load list of own numbers: Couldn't get MSISDN: QMI protocol error (16): 'NotProvisioned'
We're bumping the current "INFO" level messages to the new "MSG"
level, also making the new level the default.
The old "INFO" level will be used to setup an intermediate level of
logging which is not as verbose as "DEBUG" but still provides some
capabilities to analyze the behavior of a modem.
It is possible that SIM IMSI might change in roaming conditions for a sim.
Register for UIM refresh indication always and reprobe if ICCID or IMSI changes for QMI modem.
We no longer have separate mm_base_modem_process_sim_event() and
mm_broadband_modem_sim_hot_swap_detected() methods. The only
difference between both of them was that one of them would attempt to
cleanup the ports context associated to the SIM hot swap event logic
as soon as a swap was detected, in order to avoid queueing up multiple
such events.
The previous logic wasn't working well, though, as there could be
mixed AT+QMI or AT+MBIM devices that would also require that same
cleanup and so we didn't always know which one should have been
called.
Now we have a single mm_iface_modem_process_sim_event() method, which
will trigger the reprobe and disabling, but which will also perform
the cleanup of the SIM ports swap setup as specified by the
implementation.
So, if a plugin explicitly initializes the serial ports context for
SIM hot swap handling, it should also explicitly clean it up.
Also, the initialization of the serial ports context for SIM hot swap
handling is no longer done automatically for all modems, it will be
done only for those modems using it; i.e. the modems that explicitly
report support SIM hot swap handling using AT URCs.
This property is used in the MMIfaceModem to flag whether the SIM hot
swap setup has been performed or not. The flag is now moved to the
iface-specific private context.
The property was also used in AT-based modems, so that implementations
supporting the SIM hot swap via AT URCs could flag the upper layers
whether the enabling of the feature was done correctly or not, and if
so, create and keep the AT ports context open. But this feature only
made sense in AT-based modems, i.e. an MBIM modem that detects SIM hot
swaps via MBIM indications exclusively should not require the AT ports
context open for anything. The check in the MMBroadbandModem object
has therefore been removed, and the logic will be updated so that it
only applies to AT-based modems.
The signal and access tech loading operation was using a context that
contained both overall state and state specific to the current
attempt.
The overall modem state is now moved to the iface-specific private
context, and the state specific to the operation is kept in a GTask
that is bound to the ongoing loading operation.
Avoid keeping separate per-operation contexts, it doesn't make
sense. Just have one single Private context for the whole interface
where we can add support for all operations performed by the
interface.
When initializing the Modem interface, we set the signal strength
to the default value (0%) and we are certain this is the recent value
until the modem reports the actual signal strength if available.
Therefore, mark the signal strength as recent instead of cached.
We remove the built-in FCC unlock procedures from the ModemManager, we
will no longer run them automatically, and instead rely on external
scripts/programs to do that.
Packages providing the external FCC unlock tools can install them in
${pkglibdir}/fcc-unlock.d.
Users manually enabling external FCC unlock tools can install them in
${pkgsysconfdir}/fcc-unlock.d.
The user-enabled path takes precedence over the package-enabled one.
In some modems, the modem's radio can be ON when no SIM card is present.
In this case, the modem is in failed state, and the host cannot set the
power state to LOW. Since we we will allow the host to set the power to
LOW, we should allow it to set it back to ON.
Prior to this change, a hotswap on the inactive slot would result
in reprobe of the modem. With this change, the sim object would be
updated, but no reprobe will be performed. The advantage is
1) we do not drop connections on the active slot
2) Slot status on the inactive slot is susceptible to firmware bugs.
We have seen scenarios where the inactive slot is reported as
absent/ iccid={0}, followed by a correction. We should not
reprobe the modem if our active slot hasn't changed.
There are modems (e.g. Nokia, Thuraya, Iridium) which don't require or
don't support power management, and therefore there is no way to
either load or update the power status.
In those modems we just assume ON is the current and only value (set
in the skeleton during initialization) and so when we attempt to
update the power state to ON during enabling, the logic should not
break.
Fix the logic by making sure the requested_power_setup() function
pointers are only checked for validity after ensuring we're not
already in the desired power state.
