The PA will be unconditionally turned. This makes it possible
that in case of a crash, the PA will be turned on and then we
will do the temperature measurement and turn it off again. There
are no known crashes with the sysmobts-mgr right now so the risk
seems to be okay. In case we can't switch off the PA we have no
way to escalate it right now. We have not seen a dead uc either
so the risk is okay as well.
We can't switch the PA back on once we reach the normal level
as the BTS might transmit with full power and we would need more
current than the power supply/rails can carry. So leave the
system off right now.
What is missing is to use the OML router to actually inform
the BSC that something bad has happened at the BTS.

Check the temperature and move between "NORMAL", "WARNING"
and "CRITICAL" state. We will only return from CRITICAL to
WARNING when the temperature has significantly changed, and
when being in state "WARNING" we enter an intermediate state
to allow an easy hysteris.

We haven't done anything with the result of the micro controller
query and querying every six hours for the temperature of the
system will not help us. We need to query the temperatures more
frequently but avoid writing to the eeprom too frequently so we
will start another timer for that.

We want to know which componets are enabled and the voltage and
current used by the components.

Use it for the ipaccess-find response and for the sysmobts
classification code. This can be used by the vty in a second.
|
|
Move the init and polling into the sysmoBTS related part. In the
future we should have _one_ temperature control.

Move the code to a separate file to keep things nicely apart
of each other.

Harald is right and that the code is generally not ready
for inclusion. I fell victim of trying to finish it while
the code is not ready at all. It is better to re-introduce
the patches in a smaller and more tested way.
The right way would have been a branch were ready things
are split-off the main/wip commit until everything is ready.

This reverts commit c64d42573894d8295b58b268a64541c914b69bcd.
There are unfrtunately still too many problems with this patch to be
merged at this point.

Make the sysmobts-mgr send a manufacturer O&M message with the power
reduction we want the sysmobts to apply. The sysmobts will handle
this message and set the new tx output power. An ACK/NACK will be
send as a response to the power reduction.

sysmobts-manager
Make the sysmobts listen for OML messages on a Unix Domain Socket.
Messages passing a sanity check will be forwarded to the BSC.
In case the sysmobts-mgr detects a temperature above or below
temperature threshold an OML failure message will be sent
to the BTS.
[moved confinfo into the #ifdef BUILD_SBTS2050]

I have extended the principal function that we use for requesting
information to the microcontroller for switching off/on the board
and the PA. And I have extended it for requesting the power status
information of the board and the PA.

Add function for requesting the temperature information to the
microcontroller. I have added a function that we can extend
for requesting more information but in this case we only need to
know the temperature.
I have added to a microcontroller temperature handling function
in the manager for monitoring this information.

For testing/trial it is better to not write to the EEPROM
but it is still good to see how the logic is working.

This daemon is taking care of counting the number of hours in operation
and to watch the system temperature as determined by internal
temperature sensors.
Later, it will export an external interface for firmware reload, as well
as a way to raise OML ALARMs in case of temperature issues or other
problems.
