This new object allows configuring the filter rules applied to the
device ports. By default, for now, it implements the same rules as the
MMKernelDevice is_candidate() method, which is obsoleted.
And only define WITH_SYSTEMD_SUSPEND_RESUME when enabled.
We already have other systemd specific features under the
--with-systemd-* name scheme, so consolidate that, given that we don't
have any other method to support suspend/resume notifications.
This logging is available if the software was build with the configure
option --with-systemd-journal.
It will be enabled by default if libsystemd is found.
The runtime parameter --log-journal enables to output of log messages
to the systemd journal.
Please note that the journal priority field has the same value as the
syslog level so no conversion is required here.
The whitelist made all platform TTYs managed by the 'atmel_usart'
kernel driver probed by ModemManager, which isn't something we want,
as most of these aren't broadband modems.
We leave the logic supporting the ID_MM_PLATFORM_DRIVER_PROBE udev tag
as there may be a case where the user does need ModemManager to probe
a given platform TTY.
During modem initialization we detected the flow control settings
supported by the modem, and selected the best one to use from them,
notifying it to the device via AT+IFC. The device was therefore
instructed to use that flow control setting for data transmission in
the TTY (i.e. not during AT control commands).
The missing thing was to also configure ourselves our end of the
serial port with the same flow control settings when getting into data
mode. By doing it ourselves, we avoid requiring any explicit setting
in pppd for flow control; pppd can assume the flow control settings
are already the expected ones.
Worth noting that all this setup is completely ignored for TTYs
exposed directly via USB.

Instead of relying on the udev daemon and GUDev to manage the devices reported
by the kernel, we can now run ModemManager relying solely on the kernel events
reported via the new ReportKernelEvent() API. Therefore, the '--no-auto-scan'
option is implicit for the ModemManager daemon when udev is disabled in the
build.
Additionally, a new custom implementation of the kernel device object is
provided, which uses sysfs to load the properties and attributes required in
each kernel device, instead of using a GUdevDevice.
The udev rule files are kept in place, and a simple custom parser is provided
which preloads all rules in memory once and then applies them to the different
kernel objects reported via ReportKernelEvent(), e.g. to set port type hints.
A simple unit test setup is prepared to validate the udev rules during the
`check' Makefile target.
The mm_base_modem_grab_port() now receives a MMKernelDevice directly from the
plugin, which is then stored in the MMPort corresponding to the port.
This means that we have direct access to e.g. all properties set by udev rules
everywhere, and we don't need additional GUdevClient objects (e.g. like the one
used in the Huawei plugin to detect NDISDUP support during runtime).
For virtual ports (e.g. generated during unit tests), we have a new 'generic'
kernel device object which just provides the values from the kernel device
properties given during its creation.
Instead of relying constantly on GUdevDevice objects reported by GUdev, we now
use a new generic object (MMKernelDevice) for which we provide an initial GUdev
based backend.
We try to combine in common envvars the compiler and linker flags shared by the
different components, and where possible, also re-using the implicit AM_CFLAGS
and AM_LDFLAGS variables that automake provides, and which apply to all objects
being built in the same Makefile.am.
The internal libmodem-helpers.la library is also renamed to libhelpers.la
Instead of providing explicit dependency rules to generate the enum types
support files before they're first used, just pre-generate them before building
anything. Maintaining the explicit dependency rules is not really worth it.
Build all targets, except for CLI tools (mmcli, uml290), with special
flags needed for collecting code coverage information when the build has
been configured with --enable-code-coverage.
Three new targets are available in the top build directory:
- `check-code-coverage' runs the test suite and generates a code
coverage report,
- `code-coverage-capture' generates a code coverage report from already
collected data, which can come in handy when one wants to see code
paths touched by a particular test,
- `code-coverage-clean' removes the collected coverage data and the
generated reports.
It's pointless to have libmm-common around, just merge it into libmm-glib and
make ModemManager depend on libmm-glib directly. At the end, the non-common
stuff in libmm-glib is really minimal.
For those who don't care about the QMI support through libqmi-glib, or if you're
stuck with glib 2.30 (libqmi-glib requires 2.32), this configure switch allows
disabling the QMI support completely.
The logic to detect cdc-wdm ports is still in place, but the QMI probing is
never launched at them. Also, all QMI-related objects won't be compiled.
