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

The FPGA codebase was removed from the UHD repository in 2014 to reduce
the size of the repository. However, over the last half-decade, the
split between the repositories has proven more burdensome than it has
been helpful. By merging the FPGA code back, it will be possible to
create atomic commits that touch both FPGA and UHD codebases. Continuous
integration testing is also simplified by merging the repositories,
because it was previously difficult to automatically derive the correct
UHD branch when testing a feature branch on the FPGA repository.
This commit also updates the license files and paths therein.
We are therefore merging the repositories again. Future development for
FPGA code will happen in the same repository as the UHD host code and
MPM code.
== Original Codebase and Rebasing ==
The original FPGA repository will be hosted for the foreseeable future
at its original local location: https://github.com/EttusResearch/fpga/
It can be used for bisecting, reference, and a more detailed history.
The final commit from said repository to be merged here is
05003794e2da61cabf64dd278c45685a7abad7ec. This commit is tagged as
v4.0.0.0-pre-uhd-merge.
If you have changes in the FPGA repository that you want to rebase onto
the UHD repository, simply run the following commands:
- Create a directory to store patches (this should be an empty
directory):
mkdir ~/patches
- Now make sure that your FPGA codebase is based on the same state as
the code that was merged:
cd src/fpga # Or wherever your FPGA code is stored
git rebase v4.0.0.0-pre-uhd-merge
Note: The rebase command may look slightly different depending on what
exactly you're trying to rebase.
- Create a patch set for your changes versus v4.0.0.0-pre-uhd-merge:
git format-patch v4.0.0.0-pre-uhd-merge -o ~/patches
Note: Make sure that only patches are stored in your output directory.
It should otherwise be empty. Make sure that you picked the correct
range of commits, and only commits you wanted to rebase were exported
as patch files.
- Go to the UHD repository and apply the patches:
cd src/uhd # Or wherever your UHD repository is stored
git am --directory fpga ~/patches/*
rm -rf ~/patches # This is for cleanup
