Some modems are able to handle some proactive commands in their
firmware or otherwise, if the command doesn't require input from user.
Nevertheles ofono may need to update internal state or notify the user
where necessary. With this api the driver can notify core that a
command is being executed in the modem or that a command is finished
executing and the TERMINAL RESPONSE has been sent to SIM. It would
also be possible for a driver to handle a command.
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.
