Summary:
This change will allow correct args to pass from mboard to dboards,
that in turn can be useful for dboard manager.
Details:
In N310, the dboard manager needs the time source to be updated before
calling update_ref_clock_source(), because it will trigger a reinit of
the dboard, for which the time_source is essential to determine correct
clock synchronizer settings.
The special case is the white rabbit time source needs a different
internal ref_clock_frequency for the clock synchronizer than the passed
in ref_clock_freq.
This provides a new utility for MPM devices (usrp_update_fs.py), which
goes through all the necessary steps to update a filesystem.
Will trigger a mender update, but the tool is not specific to Mender
and can be changed to use other methods in the future.
When reloading the Periph Manager (as when we run the image loader),
we need to run the RPCServer `__init__` function in order to reset the
cache of RPC methods. Otherwise, that cache keeps stale references to
old functions (and prevents garbage collection).
It may be possible to reset the method cache some other way, but the
`_methods` attribute of RPCServer is Cython, and doesn't seem to be
accessible in our Python code.
Adding MPM Git hash and version to the MPM device info. This
information is currently only available through logs when MPM starts
(it is the first log message in usrp_hwd.py). Adding it to the device
info makes it accessible to any application which checks that, such as
uhd_usrp_probe.
- For different ref clock frequencies, the ref_counter should change
and not the n_counter.
- The charge pump should be set to normal mode and tristate as that
would prevent the PLL to lock.
- ref_clock_(int/ext) test was not changing adf400x driver settings
for new ref clock frequency. Therefore, changed the implementation
to use uhd_usrp_probe --sensor to set clock_source and get
'ref_locked' sensor value
Added set_sync_source method to set both the time and clock sources
without forcing a re-init twice. Modified the existing set_time_source
and set_clock_source methods to call into set_sync_source.
EEPROM parsing in MPM was ignoring the dt_compat number (MPM doesn't
need it), so when the dt_compat number was non-zero, the CRC
calculation was incorrect. CRC calculations are now done on the raw
data.
- Fix the syntax to open mboard-regs UIO objects, and change the open()
and close() functions to be private.
- We were calling open() twice in every context manager line- once
manually, and once in __enter__. This commit corrects those usages, and
allows the context manager to fully manage the opening and closing of
UIO objects.
Fixes the list of epprom-tools to be built in CMake. The list of tools
is appended, instead of being overwritten by device-specific tools.
Fixes: 300a5e3f6e [mpm: initial commit of E320 code]
The tests for white rabbit and SFP loopback require a specific FPGA
image. We now check if that image is already available before running
uhd_image_loader.
Adding the following sensors:
- Catalina temperature, RSSI, and LO Lock sensors
- GPS lock, time, TPV, and SKY sensors

When a device is re-initialized without any changes (e.g.,
master_clock_rate, ref_clock_freq) then we can skip the initialization
sequence and move on. This shaves a significant amount of time from the
init sequence.
Fast re-init can be overridden by providing the `force_reinit=1` device
arg.
Fix issue with dt-compat and mcu-compat numbers not working for
the case where 0 is a legitimate dt/mcu compat number.
This can happen if a Rev2 board (1 in hardware) shares a DT or
MCU firmware with the Rev1 board (0 in hardware).

- Refactoring component (FPGA, DTS) updating functions out of
n3xx.py into their own components.py. The ZynqComponent class now
defines the methods to update these two components.
- Adding super().__init__() to the PeriphManagerBase class. This is
needed to get the multiple inheritance used in N3XX now to work, and
(apparently) good Python practice.
- Refactoring GPSd interface to be instead wrapped by a
GPSDIfaceExtension class. This class will faciliate "extending" an
object, allowing that object to call the GPSDIfaceExtension methods as
their own.
- New MPM devices (or whatever else) can now use the GPSDIfaceExtension
class instead of writing their own GPSDIface handling functions.
- N3XX now instantiates a GPSDIfaceExtension object, and extends
itself. This means that an n3xx object can call the `get_gps_time`
method as its own, for example.
- N3XX must get through initialization in order for the GPSd methods
to be registered.
Moving the RFNoC crossbar base port to the class overridables. MPM
devices may need to reserve different numbers of ports for non-blocks;
this can now be done by overriding the crossbar_base_port.
Introduce dt-compat and mcu-compat fields into the eeprom
structure.
For the motherboard eeprom this is straightforward, since
there's still padding bytes that could be (ab)used for this.
On the dboard side more creativity is required and the
original revision field of 2 bytes is reduced to only
one byte revision and one byte dt-compat.
Since this will only affect new units being backwards
compatible with older versions of the bootloader is not
an issue.

This manager first detects all valid Ethernet devices. The checks for
validity happen across multiple calls in a non-atomic fashion, so it's
possible to end up with inconsistent results. To avoid such issues, we
filter results without talking to the network stack as a final pass.
Because the detection of valid Ethernet devices happens across multiple
calls in a non-atomic fashion, we cannot assume that a device passed to
net.get_iface_info() actually has a valid IP address, so we don't make
that assumption.
Since there is no simple mapping from an arbitrary tuple of mboard- and
dboard info dictionaries, we use generate_device_info() to figure out
the product key.
In the N3xx series, the motherboard ID and the device ID can differ. For
example, the N310 could share the same motherboard with a different
device that uses different daughterboards.
This changes the sorting algorithm for the xport<->SFP mapping. When
multiple SFPs are used, this sorting will avoid a criss-cross mapping
(e.g., mapping ports 0 and 1 of 0/Radio_0 to different SFPs).
- Replace mykonos finish_initialization with async version
- Replace myknonos setup_cal with async version
- Remove disable_timeout on rpc_server init()
Usually, the current timeout is fine, but there are cases when a lot of
RPC traffic could drown out the reclaim calls. 5 seconds is an
experimentally derived safe value.
Separating Boost.Python bindings into device-specific files. N3XX code
now lives in n3xx/pyusrp_periphs. Only one src file should be added for
pyusrp_periphs.so by CMake.
Bump maximum supported motherboard revision to 5 (RevF),
to support upcoming motherboard revisions.

Adding address offset to all MBoard and DBoard EEPROM reads. This

UIO objects now count references on open and close calls. This should
prevent problems with nested function calls that open/close the same

References counts are not atomic -- this is intended for nesting with

The log output at level 'INFO' was pretty cluttered. This cleans up the
log messages at the higher levels. In some cases, log message typos or
capitalizations were also fixed.
The FPGA and MPM version as well as the description of the device
("N300-Series Device") and its name (its the hostname) are now properly
reported coming from MPM, properly saved in the prop tree, and
uhd_usrp_probe can nicely display them this way.
-Adding MboardRegsControl.get_fpga_type(), which reads the SFP info
registers and determines the FPGA image type (HG, XG, AA, etc). This is
a minor FPGA compat number bump.
-Adding N310._update_fpga_type(), which updates the component
information using the get_fpga_type() function described above. This
information can then be accessed through get_component_info().
The lines removed here are no longer needed, get rid of them

Before, it was possible to trick the RPC server in believing a
connection was remote when the incoming connection was from a local IP
address that was not 127.0.0.1.
Adding helper function to parse strings to a boolean value. We can
then use that function to parse MPM's default_args, and set enable_gps
and enable_fp_gpio. This replaces the usages of the Python builtin
bool(), which returns True for any non-empty string.
Using string expression instead of passing in a total hex value.
Now user can passed in for example: init_cals=DEFAULT or
init_cals=BASIC|TX_QEC_INIT

This splits up the transport code in mpmd_impl across multiple classes

Different types of transport (UDP, liberio) use their own distinct
