The tests spawn the service via GTestDBus framework and make
some test API call while checking libmm interface to verify
that informations are well propagated.
To be able to use the fresh built libmm typelib, I used a
wrapper script to set GI_TYPELIB_PATH (because DBus activation
process clean the environment so it is not possible to set
it directly in the file).
This requires also the install of libgirepository-dev and python3-gi
in the CI docker.

It will not be automatically enabled by the implicit
--enable-all-plugins; instead, it must be explicitly enabled with
--enable-plugin-qcom-soc.
This plugin only makes sense under very specific SoC builds, so there
is no point in always building it by default. It should be explicitly
requested only in those SoC builds that are really going to make use
of it (e.g. postmarketOS).
This plugin implements support for old Qualcomm SoCs like the MSM8916
or the MSM8974, where:
* control ports are available via RPMSG channels exported as devices
e.g. with rpmsgexport:
https://github.com/andersson/rpmsgexport
* network ports are exposed by the bam-dmux kernel driver:
https://github.com/msm8916-mainline/linux/commits/bam-dmux
Adding support for newer Qualcomm SoCs (e.g. QRTR+IPA) could be done
in a similar way on this very same plugin.
This plugin is the first and only one that implements support for a
modem device that is "built in" the system, as opposed to external
modems that may be available via USB or PCI.
The ID_MM_PHYSDEV_UID based udev tags provided by the plugin provide
the logic to bind all the SoC ports together in the same modem object,
and therefore ID_MM_PHYSDEV_UID should not be used by users to
override the ones set by the plugin.
All "rpmsg[0-9]*" ports that are considered part of the modem are
flagged as candidate, ignoring the parent "rpmsg_ctrl[0-9]*" ports on
purpose. This setup therefore assumes that the channels have been
exported already as devices (e.g. using rpmsgexport).
libqmi 1.27.2 is required to support the "WDS Bind Data Port" message.
This script mock some of ModemManager DBus interfaces (main object, Modem, Sim),
it also adds a test interface "org.freedesktop.ModemManager1.LibmmGlibTest"
which allow to inject some errors and simulate behavior:
- Add a modem object
- Emit modem state changed
- Set modem error
This script also add the possibility to log in a file for debugging purpose.
Because the stdout/stderr are not shown when the program is spawned by DBus
auto activation.
Note: Script is heavily inspired from test-networkmanager-service.py from
NetworkManager project

The autoconf macros AX_COMPILER_FLAGS_{CFLAGS|GIR|LDFLAGS} test
for compiler and linker support of various flags, and add the flags to
the generated output.
If the command-line option '--enable-compile-warnings' is specified to
'configure', a number of additional warning options is also added to the
output. This is the default.
This update requires the presence of the GNU autoconf-archive in the
system.
If ModemManager is being used in a custom system, make it easy to
unconditionally enable the Modem.Command() method, in case the modem
needs to be configured in some way that is not supported via standard
modem interfaces.
The WMC protocol was only present on older Panasonic/Verizon devices
from the 2006 - 2011 timeframe. The last device to support WMC was
the UML290 which also supported QMI (which is much more functional).
ModemManager also never used WMC support and it was never significantly
reverse engineered.
So remove WMC code from git; it'll still be in the history if anyone
cares in the future.
libmbim 1.17.4 (commit 3eeaa4248b98 "ms-basic-connect-extensions: rename
service") added a MS prefix to the Basic Connectivity Extensions
service. This patch updates the MMBroadbandModemMbim code accordingly.
This commit introduces several improvements and changes in the way
modes and capabilities are managed in QMI capable devices. It is
organized into a single commit, as all changes in all 6 operations
(load current capabilities, load supported capabilities, set current
capabilities, load supported modes, load current modes, set current
modes) are related one to the other (given that the same QMI commands
are used for both capabilities and mode management).
The primary change is related to which capabilities are reported as
supported for a given device. In the previous implementation we
allowed switching between every combination possible for GSM/UMTS+LTE,
CDMA/EVDO+LTE or GSM/UMTS+CDMA/EVDO+LTE devices. E.g. we would allow
"LTE only" and "GSM/UMTS only" capabilities for GSM/UMTS+LTE devices,
even if they would both be managed in exactly the same way. That setup
wasn't ideal, because it meant that switching to a "LTE only"
configuration would require a power cycle, as capability switching
requires a power cycle, even if no change was expected in the exposed
DBus interfaces (which is why we require the power cycle). So, instead
of allowing every possible capability combination, we use capability
switching logic exclusively for configuring GSM/UMTS+CDMA/EVDO devices
(regardless of whether it has LTE or not) to add or remove the
GSM/UMTS and CDMA/EVDO capabilities. E.g. for a GSM/UMTS+CDMA/EVDO+LTE
device we would allow 3 combinatios: "GSM/UMTS+LTE", "CDMA/EVDO+LTE"
and "GSM/UMTS+CDMA/EVDO+LTE".
The "GSM/UMTS+CDMA/EVDO+LTE" is a special case because for this one we
allow switching to "LTE only" capabilities while we forbid switching
to "4G only" mode. As the same commands are used for mode and
capability switching, if we didn't have "LTE only" and we allowed "4G
only" mode instead and rebooted the device, we would end up not being
able to know which other capabilities (GSM/UMTS or CDMA/EVDO or both)
were also enabled.
Now that we have capability switching confined to a very subset of
combinations, we can use the mode switching logic to e.g. allow "4G
only" configurations in all non multimode devices, as well as masks of
allowed modes with one being preferred, which we didn't allow before.
In the previous implementation all mode switching logic was disabled
for LTE capable QMI devices. In the new implementation, we use the
"Acquisition Order Preference" TLV in NAS Set System Selection
Preference to define the full list of mode preferences for all
supported modes.
We also no longer just assume that NAS Technology Preference is always
available and NAS System Selection Preference only after NAS >= 1.1.
This logic is flawed, instead we're going to probe for those features
once when loading current capabilities, and we then just implement the
capabilities/mode switching logic based on that.
