Pull some general functionality out of a specific test case and create
a TestBase class. Future test cases will inherit from TestBase and have
access to this general functionality.
Add unit testing framework to MPM which can be run by calling
"make test". The testing is done using the built in unittest Python
module. Tests can be run on a dev machine or on the USRP itself when
compiling natively.
The N320 has FPGA types (XQ, AQ) which cannot be derived from the mboard
regs in the same way as the non-QSFP variants. We therefore bite the
bullet and hardcode those.
When running
$ n3xx_bist ddr3
The test will now load the AA image if the BIST fails, unless the user
specifies
$ n3xx_bist ddr3 -o skip_load_fpga=1
The rationale is that by default, the AA image is the only one that
includes the DmaFIFO block.
The capability to run the DDR3 BIST is built into the DmaFIFO RFNoC
block, which is not always available. This change performs a quick check
before for its existence before retrieving the throughput values, and
thus can provide a better error message in that case.
We can't guarantee that there is actually a DDR3/DRAM FIFO block on the
image. So, don't run that test by default.
In order to run the DDR3 bist, running `n3xx_bist ddr3` is still valid.
However, it requires an image with the DRAM FIFO enabled.
Without this patch, the N320 code will rely on an error to occur to
determine the non-existence of the N321 LO distribution board. While
this works, it forces an error message where there's no error. This will
first check for the existence of the board before trying to initialize
it.
Issue: Current code loads FPGA too early while many
essential peripherals such as net clocks are not brought up.
This change will make sure those are got init before FPGA loaded.

Add an argument to the UDP xport_mgr to adjust the xport sorting. This
enables Rhodium to use a different limit from Magnesium. Previously, the
sorting method would overload a link with both of Rhodium's higher-rate
streams.
Fixes Rhodium for changes introduced in b7bab6a. The constructor call
for BfrfsEEPROM didn't match the signature, and Rhodium's EEPROM map
referred to the wrong revision.
Add method to generate GPGGA sensor data in MPM devices. This needs to
be constructed from TPV and SKY sensor data, and matches the GPGGA
sensor functionality in gpsd_iface.cpp.
Previously, the init() procedure of the n3xx class passed either
the user-provided or the default clock_source and time_source values
to initialize the clocking configuration.
When the user did not provide these parameters, the default values
were assigned, overriding whatever configuration the device was
previously initialized with. Therefore, a dboard reinit was forced
when the currently configured state of the N3xx device did not match
the default configuration (i.e. internal sources).
Now, the init() procedure still provides the clock_source and
time_source values; but, if the user does not provide the
parameters, the previously used values are assigned (i.e.
self._clock_source and/or self._time_source).
By the time MPM runs this n3xx init() procedure for the first time,
both self._clock_source and self._time_source have been initialized
with the default internal values anyways in the
_init_ref_clock_and_time() procedure.
This change prevents additional, unnecessary calls to the
set_sync_source() procedure, which ultimately causes a daughterboard
reinitialization when either a new clock or time source is requested.
The update_ref_clock_freq() procedure now updates the self._init_args
value of the Rhodium class daugtherboard objects in MPM to propagate
the latest user-selected arguments for future reference.
gpsd connection is not reliable.
Adding more error handling to re-connect during polling.
Add control flows to get_gps_time in order to give an effect of getting
the value on pps edge.
