rfnoc_num_blocks is a device arg that could be used in UHD 3.15 (and
below) to artificially skip enumeration of RFNoC blocks. Since the block
enumeration works very differently in UHD 4, this arg was never
supported there.
This removes references to this arg in some BIST files. It is not
harmful, but also serves no purpose, and could be construed as being
useful upon lecture of these codes.
The routine to identify products currently only reads the motherboard
EEPROM. The N310 and N320/N321 use the same motherboard so these devices
can't be distinguished using the motherboard EEPROM alone. This change
makes get_product_id() read both the motherboard and daughterboard
EEPROM in order to determine which N3xx it actually is.
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.
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.
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.
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.
-set_all function doesn't fit well with the GPIO api. It is rather
a test sepecific function.
-Add gpio_set_all helper to n3xx_bist.

GPIOBank is the new class, n310.FrontpanelGPIO and BackpanelGPIO now
derive from that.
Other minor changes:
- Renamed classes to FrontpanelGPIO and BackpanelGPIO in accordance
with coding guidelines
- Moved MboardRegsControl before n310 class for consistent code layout
This will enable both RevC and RevD from an MPM perspective. The
revision read back from the EEPROM is used to enable the code for either
rev.
The impact on the code is limited to the port expander GPIOs. Port
expander objects are instantiated in both the N310 MPM module as well as
the n3xx_bist executable.
When the GPS chip is non-functional, gpsd could simply fail to return a
value. In that case, the recv() call to the socket would hang
indefinitely. This adds a graceful failure for that case.
To placate fussy JSON consumers, we now avoid nested dictionaries. The
dry-run results now return a more accurate representation of the N310
system responses.
Some downstream consumers of n3xx_bist output require the error_msg key
to be in every result, even if no error occurred. The default value is
an empty string.
