EFiidf can be larger than 256 bytes, so allow callers to read
portions of the EFiidf from a specified offset. Cache EFiidf
files as blocks of 256 bytes so that it's not necessary to
read the entire (potentially large) file.
This patch fixes problem for modems that cannot terminate
DIALING/ALERTING calls with CHUP=1X. The main change is that
voicecall driver's hangup function is split into the functions
hangup_all and hangup_active.
Changes:
- In cases where hangup previously was used, hangup_all is used
if implemented otherwise hangup_active is used.
- Call in state DIALING/ALERTING is released with hangup_active if
implemented.
- manager_hangup_all will simply call hangup_all if implemented.
- manager_hangup_all will release calls in state
ALERTING/DIALING/INCOMING using hangup_active otherwise
release_specific.
The online/offline state is changed with the new set_online() modem driver
method.
In order to track atoms, there are modem states as follows:
- OFONO_MODEM_STATE_POWER_OFF
- OFONO_MODEM_STATE_PRE_SIM
- OFONO_MODEM_STATE_OFFLINE
- OFONO_MODEM_STATE_ONLINE
Atoms are added with driver methods pre_sim(), post_sim() and post_online().
Atoms are removed by modem core when the state changes.
Adding a new notify function in the netreg atom for notifying a
received Network Identification and Timezone (NITZ) indication. This
data is consumed via a nettime plugin, of which there is also an
example.
Add ofono_sim_inserted_notify function to notify the core of SIM
insertion / removal.
Make every plugin generate a sim inserted event on start. For devices
with removable card, the event should be emitted after the
plugin detects such event. For devices that need to wait for SIM card
initialization, they can emit this event later.
We no longer expose lac/ci/tech attributes obtained from CGREG
(some modems, like ISI, do not even report them for GPRS separately).
Simplify the internal gprs driver api to only report the registration
status (e.g. home, roaming, searching, not registered, etc)
