This way we benefit from:
* knowing which attributes are used/required by each object class and
* Having validation function definitions near the class going to use them
similar to the eNB patches this fixes the CA and MIMO radio
parameters. In pricinple this could also be reused for the
AmarisoftUE but since we currently don't have a means to test
it I left it for a future commit.
this patch moves the rf_dev_args creation for both eNB types
into the eNB base class, since they are identical.
the patch also fixes the arguments for all CA and MIMO configurations
Two implementations are provided:
* Amarisoft Ctrl interface (websocket)
* Mini-Circuits Programmable Attenuator (HW, HTTP API) 
in Amarisoft ENBs, if no rfemu is configured explicitly, the Ctrl
interface one is used by default, while still being possible to use the
This way we don't need to manually add new imports here or drop unusued
ones. It also makes sure local imports in all our py files is correct.
For instance, running the script already caught an issue which is added
to this patch (osmo_ms_driver/__main__.py).
This new version of the script also allows specifying subsets of
features to skip when checking for dependencies. This way, for instance
somebody not willing to use a sispm powersupply can stil check all the
needed dependencies are fine.
This new tool will make it easier to slowly make some dependencies only
used by some object test classes optional (for instance, python-smpplib
if user doesn't want to run an ESME node).
It also allows to retrieve the required debian/manually installed
packages when run with "-p" option:
Modules without debian package (pip or setuptools?):
usb [dpkg-query: no path found matching pattern /usr/local/lib/python3.5/dist-packages/usb/_interop.py]
pydbus [dpkg-query: no path found matching pattern /usr/local/lib/python3.5/dist-packages/pydbus/proxy.py]
smpplib [dpkg-query: no path found matching pattern /usr/local/lib/python3.5/dist-packages/smpplib/command_codes.py]
sispm [dpkg-query: no path found matching pattern /usr/local/lib/python3.5/dist-packages/sispm/__init__.py]
This way we avoid unconditionally importing all subclass dependencies,
and make them optional based on whether the setup has devices of that
type or not.
this allows to optionally specify a the GTP bind_address for a enb object
in the resources.conf
this address is then used for binding the listening socket for gtp connections
which, in turn, allows to run the enb and epc on the same host.
when gtp_bind_addr is not specified, addr is used by default
this is especially useful if eNB and EPC run on the same host
and ZMQ is used for RF between eNB and UE. Two eNB addresses
are needed in this case, one bind address and one "remote-accessable"
address for the UEs ZMQ radio to connect to
Some older iperf3 versions don't support the --logfile arg. Let's
instead parse the json from stdout. Old --logfile behavior is left in
code but disabled since it's a nicer (less hacky) way to get results,
because parsing from stdout means we need to avoid reading some content.
It contains simple usual setups to get started with osmo-gsm-tester,
such as creating a 4G network using srsLTE or a 2G network using the
osmocom stack (+ ofono modems).
This content is mostly specific to sysmocom's setup (thought it can
still be re-used by other people if willing to).
