* mpm: Default virtual NIC CHDR IP selectionSteven Koo2020-07-304-4/+22
| | | | | This change adds detection for setting the correct internal fpga CHDR IP address when using embedded mode.
* mpm: Fix more gevent errors on SIGTERMSamuel O'Brien2020-07-281-6/+19
| | | | | | | | | | | | | Sometimes when running usrp_hwd.py in a terminal and then canceling it with Ctrl+C, it prints a really large stacktrace into the terminal resulting from an uncaught gevent BlockingSwitchOutError. This comes from trying to block on Process#join inside a gevent signal handler. This commit resolves this issue by simply triggering an event in the signal handler which prompts a different non-daemon thread to join the subprocesses and end the parent process.

* mpm: Fix documentation and minor issues in sys_utils.GPIOBankMartin Braun2020-07-281-6/+30
| | | | | | | | | | | - GPIOBank made the assumption that all bits used where contiguous. This amends the documentation to make that more clear, and adds an assert statement to check for that. - reset_all() would reset all pins, regardless of DDR value, rendering it useless for any GPIO bank that would want to have readable pins. Fixed that by checking DDR value before resetting. - Minor amendments to various docstrings; improve PyLint score by removing superfluous inheritance from object.
* mpm: Fix gevent errors on SIGTERMSamuel O'Brien2020-07-242-5/+13
| | | | | | | | | | | | | | | | | | | | | | Sometimes when running usrp_hwd.py in a terminal and then canceling it with Ctrl+C, it prints a really large stacktrace into the terminal resulting from an uncaught gevent BlockingSwitchOutError. It seems like there was an attempt to catch this in usrp_hwd.py:kill_time(). This try-except was surrounding a call to Process.join() which, to the best of my knowledge, can't ever throw this exception. Based on my troubleshooting, this error comes from the SIGTERM signal handler of the RPC process. The handler (defined in rpc_server.py:_rpc_server_process), is just a direct call to RPCServer.stop(). When the server's backed is a thread pool, this call may block when joining the thread pool, causing gevent to complain about execution attempting to block in a signal handler. This commit resolves this issue by simply triggering an event in the signal handler which prompts a different thread to clean up the server and end the process.

* mpm: Don't index empty forwarding interface listAaron Rossetto2020-07-241-0/+1
| | | | | | If no internal interfaces are found to which to forward CHDR packets, return after printing the warning instead of attempting to index the empty list and generating an exception.

| | | | Add an entry for the internal NIC to E320.
* mpm,mpmd: Add iface type and mtu info for UDP linksAlex Williams2020-07-162-1/+4
| | | | | | This changes MTU handling for the "internal" UDP type. Because MPM echo packets will not be returned for internal NICs, use the iface's programmed MTU instead.
* mpm: Add support for internal Ethernet interfaceAndrew Lynch2020-07-164-12/+46
|
* mpm: Detect number of liberio channelsAlex Williams2020-07-162-5/+18
| | | | | Instead of using hard-coded values, detect the number of liberio channels, and only offer liberio links if they exist.
* mpm: utils: print error on minor compat number mismatch conditionallyJoerg Hofrichter2020-07-131-1/+2
| | | | | | If the minor compat number does not match (older than expected), then generate an error message only if argument fail_on_old_minor is True; generate a warning otherwise.
* docs: Add comments on mpm.confMartin Braun2020-07-091-0/+1
| | | | | This adds some more details on mpm.conf, what it does, how it works, and which keys it accepts.
* mpm: Fix various Pylint issuesMartin Braun2020-07-095-13/+9
| | | | | | | | No functional changes. Fixes for things that PyLint complains about, but are safe to change anyway, as well as a minor improvement to a docstring that referenced non-existant args. This touches files that are mpm.conf-related.
* mpm: Look for pca953x based devices by device/nameSteven Koo2020-06-113-4/+4
| | | | | | | | | | The pca953x driver introduced a change for how the "label" property populates. Instead of using the device model, it gives a device specific name. As a replacement, use device/name. This affects the tca6424 and tca6408. For the kernel change that causes this see: https://github.com/torvalds/linux/commit/5128f8d4450159f59565d247437d3bedda3994cb
* mpm: Return filesystem info from get_device_infoLane Kolbly2020-06-051-0/+14
| | | | | This commit returns information on the filesystem and mender artifact versions to clients of the MPM RPC connection.
* mpm: Return dboard_info in get_device_infoLane Kolbly2020-06-051-0/+5
| | | | | | | | | Though this information is also returned via usrp_probe, it can be useful to provide this information to trackers which scrape the get_device_info RPC call. The dboard information is split up and cast to string just to simplify parsing on the receiving end.
* mpm: Return build info in mpm_sw_versionLane Kolbly2020-05-271-1/+1
| | | | | The mpm_version key was being overridden by the MPM_COMPAT field in rpc_server::get_device_info.
* mpm: rpc_server: set correct default unpacker params for msgpack 0.6.1Joerg Hofrichter2020-03-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | msgpack 0.6.1 suggests new default parameters which ensures compatibility with the upcoming msgpack 1.0 release which will have breaking changes. The parameter changes are described in https://github.com/msgpack/msgpack-python/blob/v0.6.1/README.rst The default parameters for msgpack 1.0 will be: - packer: use_bin_type=True - unpacker: raw=False The packer use_bin_type=True option is already set in the client (mpm_shell.py) but the unpacker option raw=False needs to be set in the server (rpc_server.py) This change allows the usage of a patched version of python3-mprpc 0.1.17 which removes passing the encoding option to the Packer and Unpacker Signed-off-by: Joerg Hofrichter <joerg.hofrichter@ni.com>
* mpm: explicitly set max buffer size for msgpack unpackerAndrew Lynch2020-03-051-0/+2
| | | | | | Msgpack version 0.6 reduced the default max buffer size to 1MB which is smaller than the bitfiles. This change sets the max buffer size to 50MB which is larger than the bitfiles.
* mpm: Make contextmanagers exception-safeLane Kolbly2020-03-034-5/+68
| | | | When making context managers in Python, the yield statement has to be wrapped in a try/finally clause in order to properly clean up after exceptions happen.
* mpm: rpc: Use contextmanager for claim timeoutsToni Jones2020-03-031-33/+38
| | | | | Modify the RPC claim timeout mechanism to use a contextmanager helper function when enabling/disabling timeouts.
* e320/e310: Fix get_gpio_srcs() MPM API callMartin Braun2020-02-262-2/+2
| | | | | The Python code contained a typo which would cause a call to get_gpio_srcs() to throw an exception.
* fixup! mpm: e320/e310: Expose APIs to drive GPIO source via UHDMartin Braun2020-01-283-2/+3
|
* mpm: e320/e310: Expose APIs to drive GPIO source via UHDMartin Braun2020-01-235-80/+147
| | | | This enables the *gpio_src* APIs for the E320 and the E31x.
* mpm/mpmd: Expose APIs to drive GPIO sourcesMartin Braun2020-01-235-37/+120
| | | | | | | | | | | | | | | | | | | The N310 has a feature that allows the front panel GPIOs to be driven by various sources: The PS, or any of the radio channels. The MPM-based APIs did not expose any way to change that. Changes: - Add MPM APIs to PeripheralManagerBase and n3xx classes - Improve comments and explanations - Add host-side hooks into these new APIs in mpmd_mb_controller - Implement these APIs for N3xx The N3xx devices will have the option to set the GPIO source to "PS", or to one of "RF0", "RF1", "RF2", "RF3" (if there are four channels; the N300 and N320 can only go up to RF1). Note: The N310 radio does not have separate FP-GPIO banks for channels 0 and 1, which needs to be fixed in a separate commit.
* mpm: optionally generate XML report when running unittestsJoerg Hofrichter2020-01-221-7/+22
| | | | | If the unittests are invoked with an extra argument -x, an XML report is generated if the xmlrunner module is installed
* mpm: mg: Make set_master_clock_rate() an async callMartin Braun2019-11-261-2/+2
| | | | | | The ad9371 call set_master_clock_rate() can take a while depending on the rate change, so make it asynchronous in order not to lock out the reclaimer loop.
* mpm: e31x: Remove superfluous code from e31x_periphsMartin Braun2019-11-262-14/+2
| | | | | | | | | - ref_locked failure would throw a warning, even though this can happen in normal operations, and the return value of the get_ref_locked() function is all the info needed - get_fpga_type() doesn't need to be called from e31x_periphs, because it is not read from the motherboard registers (is read from the EEPROM)
* mpm: e31x: Fix setting of clock sourceMartin Braun2019-11-261-4/+1
| | | | | | | The clock source on E310 is always internal. This patch removes the variables regarding the clock source (since they are superfluous). This fixes a bug where self._clock_source on the e31x class would never get initialized.
* mpm: e310: Enable GPS sensorsMartin Braun2019-11-262-5/+70
| | | | The GPS sensors are pulled in via gpsd_iface.
* e310: Fix issues in MPM and UHDMartin Braun2019-11-264-163/+143
| | | | | | | | | | | - Remove superfluous INFO logging - Improve formatting in many places - Improve Pylint score in various places - Add tear_down to DB object - Simplify custom EEPROM code for E310 - Fix time source selection code - Remove references to GPS_CTRL and GPS_STATUS (are E320 only) - Move clock source control out of MboardRegs object
* mpm: Clean up code, improve Pylint scoreMartin Braun2019-11-265-101/+115
| | | | | | | | | | | | | | | | Many small cleanups: - Fix copyright headers - Fix superfluous imports - Pull some constants out of classes where appropriate - Fix formatting - Improve/fix some docstrings - Disable specific Pylint warnings where appropriate - Global catches use BaseException instead of Exception - Don't use len() for empty checks - Make sure to declare all self attributes in __init__ (note: this is particularly of interest for E310, becuase its regular init happens outside of __init__) - Compacted some E310 code that had multi-DB checks
* mpm/mpmd: Remove token requirement for device infoMartin Braun2019-11-261-1/+2
| | | | | This removes the token requirement for get_proto_ver() and get_chdr_width().
* mpm: Move common mboard regs code to common locationMartin Braun2019-11-269-736/+272
| | | | | | | | | | | | | This assumes an existence of mboard_regs_control in PeriphManagerBase and implements most TK controls there. All the *_periphs.py files can now use a common class for registers, including the TK access, but also git hash, build date, and device ID access. This also fixes two issues: - set_timekeeper_time() and set_tick_period() had a bug that would incorrectly calculate the upper 32 bits of their respective registers. - N3xx had a bug that would swap around set time now and next PPS. This got auto-fixed because the common code never had this bug.
* mpm: n3xx: Improve Pylint scoreMartin Braun2019-11-262-16/+19
| | | | | | | - Replace some `if len(seq)` with `if seq` - Replace some `lambda: f()` with `f` - Formatting - Add some pylint: disable where appropriate
* mpm: Fix calculation of link_rate for UDP xportsAaron Rossetto2019-11-261-1/+1

* rfnoc: Unify endianness of transportsAlex Williams2019-11-263-3/+3
| | | | | Ethernet now uses the same serialization of the RFNoC stream as all the other transports.
* Remove proto-RFNoC filesMartin Braun2019-11-263-6/+0
| | | | | | | This commit removes all files and parts of files that are used by proto-RFNoC only. uhd: Fix include CMakeLists.txt, add missing files
* x300/mpmd: Port all RFNoC devices to the new RFNoC frameworkMartin Braun2019-11-2615-830/+957

* mpm: gpsd_iface: Sanitize return values for get_gps_info()Martin Braun2019-11-211-8/+21
| | | | | get_gps_info() can time out, or fail for other reasons. This adds some checks to see if the return value is as expected.
* mpm: rpc_server: Reenable timeouts after components have been updatedMartin Braun2019-10-281-0/+3
| | | | | | | | | | | | 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.
