This updates the RFNoC image cores to separate the two DRAM banks on
X4xx by splitting them into "dram0" and "dram1". Previously, both DRAM
banks shared the same DRAM port, named "dram", which created some
confusion.
The Replay block has also been duplicated in the bitstreams that use
both banks, so we now have one Replay block per bank.
Original-commit: b5cfab8922e5b3f4ff13a8a64e8b0319876f13db
- Update X410 and X440 BSP YAML files to properly index clocks
- Update image core files to declare clock indices
- Update get_clocks() in MPM to return the correct values
This does not include changes to the x400_radio_control block registry.
This change by itself will thus not change behaviour.
Original-commit: f215af2ccde6420b685b4ca493c8bd71d28781cb
This adds support for the X440_X4_200 variant which supports up to
200 MHz bandwidth (250 Msps), has a DDC and DUC on each channel,
4 x 10 GbE interfaces, and no DRAM.
Original-commit: bdaba58750ce0c2ccc58769936c3c5c4a6b2d2cf
Adds a 266.667 MHz compute engine clock and uses it instead of the
radio clock for the DDC and DUC. Using a faster clock than the radio
allows the DDC and DUC to drain after a stall in the data flow.

FPGA:
- Split up MB registers that control daughterboard specific settings so
that daughterboards 0 and 1 could have different setings, in
preparation for future devices that require different settings.
This requires a compat number bump to 8.0.
- Add registers for additional RFDC information, including the
block/tile mapping of the individual channels, and information about
resampling capabilities
- Identify sections of code that would be specific to X410/ZBX and move
them to their own headers, so it's trivial to add device-specific
sections of code instead for other devices in the future.
- This includes constraints for clocks and I/O pins.
- Remove ability to do timed ctrlport transactions to the MB CPLD, this
was unused and possibly broken.
- Move daughterboard-specific code into its own code location
(dboards/zbx)
- Move X410-specific register documentation to its own location
(doc/X410)
- Refactor Makefiles to split out X410/ZBX specific components and allow
switching between device types
- Add 512-bit AXI interconnects
- Make number of timekeepers configurable (X410 keeps the single
timekeeper)
MPM:
- Required compat is bumped to 8.0
- Now supports new registers for detecting DSP capabilities and
multi-rate settings for the daughterboards
- Adds MMCM controls (currently unused)

Original-commit: c1d268917ea65dd9c5a42366014cb96d3c025223
The frontend synchronization upon time change was removed, but is
required to synchronize the RX frontend modules when sharing LOs on
TwinRX. This change restores the behavior.

Original-commit: c70b479007ab9f578577dfb5c2de6660e877d9a3
Moves X4C_100, X4C_200, C1_100, and C1_200 from experimental to
available targets and makes the needed changes to allow them to build
successfully.
Adds support for "UC" FPGA variant. U indicates that QSFP0 is unused
and C indicates that QSFP1 is 100 GbE.
Adds experimental CG_200 variant.
Original-commit: cb9609c886b156e22ae9d879fffad8d060f2ca2d
Removes the CPU_W parameter from x4xx.v and the qsfp_wrapper files. The
value of this parameter depends on the axi_eth_dma IP and therefore
should not be changed.
Original-commit: 84c49f40adc980e2968a6a844b4bdbb2d2d38c9c
The long lines were causing Debian lintian failures, so they have been
reformatted. No functional changes.

Adds a BUILD_BASE_DIR makefile variable that allows you to specify the
base directory for FPGA build outputs. This allows you to put the
output from each run of make into a unique directory, or to run
multiple instances of make in parallel with each build's output being
put in a different directory. For example:
make X310_XG BUILD_BASE_DIR=/path/to/builds
Original-commit: bc6db8409ba756bbad0d0c158ffb00c614b58fd9
Adds a BUILD_SEED make variable that can be set to a 32-bit integer,
and adds an FPGA read-only register initialized by this variable.
Changing this variable will randomly affect the FPGA build results.
This can be useful when your build fails timing by a small amount,
allowing you to build again and get different results with the same
code.
For example, you could run the following to produce an FPGA build with
different timing results from the default build:
make X310_XG BUILD_SEED=123

Set the NODE_INST parameter for each transport adapter on X4xx so that
each adapter has a unique node instance number.

This fixes some issues with the 2021.1 version of the 10 GbE IP. In the
new version, link status is sporadically detected by the Xilinx IP when
nothing is connected to the port. Also, when the SFP is inserted, the
link status goes up and down multiple times. This change fixes this by
adding a counter and only considering it "linked" when the link has
been stable for some amount of time.

This adds the ability to do IP generation and FPGA builds using the
--jobs (-j) option with Make. For example, rather than generating each
IP one after another, you can generate up to N at a time using N Vivado
instances. This greatly reduces the IP generation time. Similarly,
parallel jobs can be used to easily build different FPGA variants
simultaneously.
Because FPGA builds can consume a lot of memory, care must be taken to
ensure that the number of jobs is not too high for the amount of memory
available.
New IP make targets were added for each USRP so that IP can be built
separately from the FPGA. The IP targets are now a dependency on each
FPGA target.
For example, you can generate the IP for X310 using 4 parallel jobs
using the following command:
make -j4 X310_IP
Or, build two X310 bitstreams simultaneously:
make -j2 X310_XG X310_HG
