* rh: Enable clock synchronization error checkingHumberto Jimenez2018-11-291-7/+3
|
* mpm: rh: Remove n321 overlayAlex Williams2018-11-271-1/+0
| | | | | | The n321 overlay is no longer needed. The devices have been added to the n320 overlay because the kernel cannot tear down multiple overlays reliably.
* n3xx: Change init() procedure to reduce configuration timeHumberto Jimenez2018-11-261-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* rh: Fix update_ref_clock_freq() to update init argsHumberto Jimenez2018-11-261-0/+3
| | | | | | 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.

* cmake: Update coding style to use lowercase commandsMartin Braun2018-11-1430-343/+343
| | | | | | | | | | | | | | | | | Also updates our coding style file. Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code (with GNU compliant sed): cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done > convert.sed \ && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' \ '*CMakeLists.txt' | xargs -0 gsed -i -f convert.sed && rm convert.sed (Make sure the backslashes don't get mangled!)
* mpm:e320: fixup gps_locked typeTrung Tran2018-11-131-1/+1
| | | | gps_locked should be a bool not int.
* mpm:gpsd_iface: handle errors from gpsdTrung Tran2018-11-131-50/+87
| | | | | | | 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.
* rh: change uio access to utilize with-asMark Meserve2018-11-122-79/+85

* mpm: i2c: Open and close i2c file descriptor on every accessAlex Williams2018-11-122-24/+48
| | | | | | This will release the i2c device when it's not in use. If MPM hangs on to the i2c devices, we won't be able to cleanly change FPGA images--The kernel hangs up the process until the refcount drops to zero.
* mpm: n3xx_bist: Add QSFP loopback to BIST testsAlex Williams2018-11-071-1/+45

* mpm: Add basic driver for QSFP board's retimerAlex Williams2018-11-074-0/+142
|
* mpm: Add convenience function to pull i2c bus from device treeAlex Williams2018-11-072-0/+37
| | | | | This function grabs the i2c character device path from the OF_NAME property. That property must be unique in the device tree!

* rh: Phase DAC configuration clean-upHumberto Jimenez2018-10-301-6/+4
| | | | | | | | | | | | | | | | | | | | | - Confirmed the Phase DAC to be initialized at mid-scale. - Confirmed the Phase DAC step resolution for fine clock shifting. The clock synchronization algorithm relies on the Phase DAC to fine shift the sampling clocks on each daughterboard. Only a certain number of DAC codes are required for the actual clock adjustment, thus a different range of codes may be chosen by initializing the Phase DAC with a given value. With the selected range, one may measure the Phase DAC's linearity and step resolution, which defines how many steps are required when performing the fine shifting of the clocks. After initializing the 16-bit Phase DAC at 25%, 50% (mid-scale), and 75%; it was found that the clock distribution PLL locks relatively faster when using mid-scale (2^15). By testing the Phase DAC's linearity, it was confirmed that the circuit resolution is 1.11 ps per code.
* rh: Deterministic latency optimization in JESD204BHumberto Jimenez2018-10-301-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | - Optimized JESD204B RX/TX links' latency. - Made JESD latency constant across supported frequencies. - Checking RX SYSREF capture in the FPGA deframer block. The JESD204B standard can be linked in such a way to produce a repeatable, deterministic delay from the framer to deframer. This is accomplished by setting up a LMFC (local multiframe clock) in both devices. The LMFCs are reset whenever a SYSREF edge is captured by the framer and deframer. Therefore, it is simple to control the LMFC rising edges in each device by implementing variable delay elements on the SYSREF pulses to the framer and deframer. Latency across the JESD204B TX/RX links should remain constant and deterministic across the supported sampling_clock_rate values. By testing the roundtrip latency (i.e. FPGA -> TX -> RX -> FPGA) with different delay values in the FPGA, one may decrease the latency and provide enough setup and hold margin for the data to be transfered through each JESD link. It was found that a different set of SYSREF delay values are required for sampling_clock_rate = 400 MSPS to match the latency of the other supported rates.

| | | | | | This change to add skip_rfic as an device argument. skip_rfic should be only used in ref_clock bist tests to bring down the test time.

* mpm: dboard_manager: add more args to update_ref_clock_freqTrung Tran2018-10-123-8/+10
| | | | | | | | | | | | | | | 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.
* mpm: Add usrp_update_fsMartin Braun2018-10-092-0/+195
| | | | | | | 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.

* n3xx: e320: fixing GPSDIface sensor namesBrent Stapleton2018-09-262-2/+2
| | | | | N3xx and E320 were registering GPSDIface names as get_*_sensor instead of just the sensor name. Fixing this to now register the sensor name.

* tools: Fix handling of 0-valued dt-compatAlex Williams2018-09-121-1/+3
| | | | | | A value of 0 for dt-compat would cause db-init to use the rev instead. This fixes the check to be on number of args instead of the dt-compat value.

* mpm: reset the RPC server upon reloadBrent Stapleton2018-08-271-0/+10
| | | | | | | | | | | 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.
* mpm: add Git hash, version to device infoBrent Stapleton2018-08-202-1/+13
| | | | | | | | 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.
