The nokia-gpio plugin should not try to create symlinks to relevant gpio
pins under /dev/cmt, since the location it is looking is no longer
correct on newer kernels and it might change again in the future. This
patch removes code from nokia-gpio that tries to create a symlink.
Users will now need to symlink the modem gpios to /dev/cmt themselves.
On the 4.13 kernel, this can be done by, for example, adding a udev rule
to:
# ln -sf /sys/bus/hsi/devices/n900-modem /dev/cmt
The HUP results in errors in gatio which will deref parts
of the AT channel. This makes it impossible to recover and
send further AT commands after the HUP.
This is needed to find out the maximum fragment size that this device
supports. The minimum length specified in the spec is 64, however 512
bytes is recommended.
We also attempt to parse how many simultaneous commands can be
outstanding at a given time. In theory MBIM supports multiple
outstanding commands through the use of transaction-id matching, but it
seems some devices only support a single outstanding command at a time.
This patch fixes up some fallout from the merging of the udev and udevng
modules.
i) The 'serial' modems in question are not necessarily serial modems at
all; for example, the N900 ISI modems appear as network devices and don't
have a devnode. This patch relaxes the requirement that a devnode exist.
ii) The modem driver was being set to 'legacy', which is a remnant of
an earlier approach to merging these modules. The driver needs to be
properly set to the value of the OFONO_DRIVER property in order for the
setup function to be found.
iii) The serial modem's private data was being added to the modem
structure incorrectly...
In particular point iii) above shows that there is essentially nobody
using these devices which makes modifications in this area tricky.
Gemalto modems have hardware related commands, allowing to monitor voltage
and temperature. These parameters will be accessible on DBus interface:
org.ofono.HardwareMonitor.
- Create the DBus method table with one entry: GetStatistics. This method
would return temperature and voltage values.
- Create a dedicated structure to handle the DBus methods.
- Create enable/disable functions to handle DBus interface registration.
This adds handling for ServicesResolved signal which tells when BlueZ
is done resolving the device services so the code will no longer ignore
devices that got its services resolved after Paired signal.
In case the UUIDs are not updated, as they are still being resolved, when
Paired property changes a modem will never be registered.
In order to fix this problem allow modems to be registered directly
during NewConnection.
This follows the same pattern as the Telit QMI modems, routing the
setup through a QMI driver. I think this can be cleaned up somehow,
but for now this at least provides support for these two modem models
so that others can aid in testing.
...and disable old udev code by shorting it out in it's init() function.
The check_device function is augmented to differentiate between USB
and serial devices:
- if the device sits on a USB bus, the device is handled as before
- if not, an attempt is made to handle the device as a serial device
This adds, but does not hook up, support for simple serial modems. These
modems generally have only a single device node so are simpler than the
USB devices which generally have different device nodes for different
functions. These modems are currently handled by udev.c, but this
functionality will allow to remove that module completely in a later patch.
- A new "device_info" type is created called serial_device_info
- the function add_serial_device sets up a modem_info structure and a
serial_device_info for the device
- A reference to the device's udev node is saved in the device info
- The device driver is retrieved from the OFONO_DRIVER environment variable
which needs to be set up by some udev rule
- Setup functions are added for these types of devices: a common function
setup_serial_modem covers the generic (simple) case, whereas modems
with special requirements are given their own setup functions to handle
the special bits
- Modem destroy needs to know the "device_info" type in order to clean
up properly, so a 'type' value is set on the modem_info structure to
guide selection of the proper cleanup function
Adding a modem boils down to finding the device in the hierarchy with
the OFONO_DRIVER property. The original code special-cased the property
being on the device itself rather than on a parent device. This patch
combines the two cases.
This patch simplifies and cleans up the check_usb_device function a bit
by doing the two following (slightly intertwined) things:
1) The parent "usb_device" is searched for early in this function and this
device will always have the ID_VENDOR_ID and ID_MODEL_ID properties.
As such, we can get them from this device and thereby be certain that
we _always_ have them available.
2) The logic of iterating the vendor_list table is cleaned up. It's
easier to follow and won't be any less efficient.
Telit QMI modems have a problem with the low-power operating modes.
After entering and leaving such a state, UIM service does not return.
The sim card is still marked as powered-down. The QMI interface does
not have a way to power it back on.
To avoid this, keep modems with the "AlwaysOnline" flag online
in the disable-modem and offline-modem procedures.
On E3372 after a GPRS disconnection, modem AT channel (used by PPP) gets
disconnected (G_IO_HUP and G_IO_ERR are detected in received_data
in gatio.c).
After that all connection attempts fail because we are not able to send
any AT commands on modem channel (it is closed).
With this patch, when this behavior is detected, we close gprs context
driver, reopen AT channel and gprs context driver.
This plugin allows to provision gprs-context data based on MCC and MNC.
This is useful when provisioning using mbpi fails (either because you
are using a private APN or because there are multiple internet type context
for your operator in mbpi database).
Config file is STORAGEDIR/provisioning.
Config file should look like that:
[operator:MCC1,MNC1]
internet.AccessPointName=apn1
internet.Username=myUsername
internet.Password=myPassword
internet.AuthenticationMethod=pap
internet.Protocol=ipv6
[operator:MCC2,MNC2]
internet.AccessPointName=apn2
The only mandatory parameter for each operator is internet.AccessPointName.
Parameter description:
internet.AccessPointName: APN
internet.Username: Username
internet.Password: Password
internet.AuthenticationMethod: authentication method.
Possible values are:
- pap
- chap
Default is chap if unset.
internet.Protocol: protocol
Possible values are:
- ip: ipv4
- ipv6
- dual
Default is ip if not set.
All parameters are prefixed with internet to be able to extend this plugin
to other type of contexts (MMS, ...).
At least firmware version 12.00.405 on the UE910-EUR otherwise
closes the AT command port whenever the PPP connection is
dropped, and we'd be left in a funny state.
Telit modems HE910 and UE910 share the same USB
vendor and device IDs (1bc7:0021) but they are
different devices.
HE910 is HSPA Class 14/6 and UE910 is Class 8/6.
Both come in voice-enabled variants.
HE910 also comes in variants with built-in GPS.
Add a new function setup, based on telit, to handle Gemalto P-family
discovery. The setup looks for USB interfaces:
application=/dev/ttyUSB2
gps=/dev/ttyUSB1
modem=/dev/ttyUSB3
Actual cinterion plugin is not compliant with newer Gemalto modems.
Gemalto plugin is based on cinterion with a custom struct to handle the
interfaces Application and Modem.
When the modes are modified with AT^SETPORT="FF;12,1,16", this modem
and pcui will appear using different ids. Update the interfaces
identifier accordingly.
The huawei E3372 exposes two USB tty at /dev/ttyUSB0 and /dev/ttyUSB1
/dev/ttyUSB1 is properly detected as modem.
/dev/ttyUSB0 is the pcui.

When a modem is being removed, all of the modem's atom watches have
already been cleaned up. Trying to remove it again results in a crash.
Fix by registering a destroy callback which will be notified when the
atomwatch has been removed.
Added 'sofia3gr.ThermalManagement' interface to sofia3gr plugin and
floated 'TransmitPowerThrottling' as an ofono property under that,
to support modem throttling.
'sofia3gr.ThermalManagement'
1.Will be available ONLY if modem throttling is supported in RIL.
This is determined by sending a RIL request during ofono start,
to get current throttling state. If it succeeds, interface is
published otherwise not.
'TransmitPowerThrottling'
1.GetProperties will be allowed both when modem is ON & OFF.
2.GetProperties will be serviced by looking it up from state
information maintained inside ofono. No RIL call will be made.
3.SetProperty will be allowed ONLY when modem is ON.
4.SetProperty request will be forwarded to RIL ONLY if
new state != current state. If RIL request succeeds, state
information will be updated and also, a property change signal
will be emitted.

Udevng layer is changed in order to support Sierra QMI modems like
MC73cxx. Identically to Huawei modems, these modems are parsed by
setup_sierra. If QMI interface is detected, the Gobi modem driver is
selected.
Unfortunately, MC73xx chips seem to have a broken QMI UIM interface.
The qmimodem-legacy is so forced in setup function.
At gprs atom 'probe' state, max cid query may fail due to rild
status isn't RADIO_STATUS_ON. It causes gprs atom is removed, gprs
feature is inavailable. Move gprs atom creating to 'post_online'
state to make sure rild status is RADIO_STATUS_ON when query max
cid.
