When updating a component like the FPGA, the timeouts for reclaiming get
disabled, because the update can potentially take a long time, during
which the RPC server might not be available.
There was a bug that didn't re-enable the timeouts. The most common case
where this causes issues was when the Ethernet connection was severed
during FPGA reloading, which could lead to UHD losing connection with
MPM altogether (for example because SFPs would come up with a different
IP address). In that case, MPM would remain unreachable until the next
reboot.
Provides a more useful error message if the EEPROM cannot be found at
the specified address. Without this change a generic index out of range
error is raised.

Some close-in noise was observed on TX when using external references.
This change reduces the noise by changing U19 to select the GPSDO when
references are set to external. Also included is a change to properly
read and apply settings from the configuration file. This allows the
user to further quiet the transmission by adding 'enable_gps=False' to
the configuration file in order to power off the GPSDO.

When using enable_gps=0, the power to the LTE-Lite GPS chip is turned
off, and neither the reference sources (time/clock) nor the
location/time data (via gpsd) can be used.
This commit disables the gpsdo options for the set_time_source,
set_clock_source, and set_sync_source when enable_gps=0 is used, and
adds logging to inform the user about this.
This behaviour is consistent with X310, where `gpsdo` is only a valid
reference if the GPSDO module is plugged in.
The manual was also updated accordingly.
Openembedded release warrior includes python3-gevent 1.4.0 which
leads to the following error when starting usrp-hwd.py:
ImportError: cannot import name 'BlockingSwitchOutError' from 'gevent.hub'
This commit fixes the issue.

This value should be 9 to correspond with the rev J motherboards.
This property was renamed to mboard_last_rev_compat in a previous commit.
But mboard_max_rev is actually a more accurate description,
since it specifies the latest hardware revision that the software
is aware of. I renamed all references back to mboard_max_rev.
This does not change the MPM/UHD API, but it makes the set_freq() call
asynchronous on the MPM side. The upside is that it will release the GIL
if the set_freq() call takes too long, e.g., because of MPM
calibrations.
- Fixes a case where the e320 would be unable to lock to an external 10 MHz
reference
- Previously, calling set_time_source would set the reference clock source to
internal as a side effect
Newer revisions of the E320 and N3xx motherboards use EEPROM version 3,
and store a rev_compat field. The rev_compat is the last revision that
this hardware is compatible with. We now use that instead of simply the
revision.
This includes a rev_compat field, which we can use to identify the last
hardware revision this hardware is compatible with. Example: Say the
current hardware revision is 7, but it is compatible with version 5,
then we store 7 as the current rev, and 5 as the rev_compat. Software
can now check the rev_compat rather than the current rev for
compatibility. This makes MPM more future-proof against minor,
compatible hardware changes.
- Turns the E310 into an MPM device (like N3xx, E320)
- Factor out common code between E320 and E310, maximize sharing between
the two devices
- Remove all pre-MPM E310 code that is no longer needed
- Modify MPM to remove all existing overlays before applying new ones
(this is necessary to enable idle image mode for E310)

If the number of channels for embedded mode streaming is 4
(1 for ctrl, 1 for async messages and 2 for data ), we need to
mux the data transport. This is needed for E310
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.
