\section{\label{chapterminus1:thesis}Master Thesis}
|
||||||
|
The master thesis including all self developed source code is
|
||||||
|
available by git via
|
||||||
|
|
||||||
|
\begin{verbatim}
|
||||||
|
git clone git@gitlab.ethz.ch:nicosc/master-thesis.git
|
||||||
|
\end{verbatim}
|
||||||
|
|
||||||
|
It can be browsed online on \url{https://gitlab.ethz.ch/nicosc/master-thesis}.

\section{\label{chapterminus1:thesis}Xilinx Toolchain}
|
||||||
|
A prerequisite for building the NetFGPA source code is the
|
||||||
|
installation of
|
||||||
|
\begin{itemize}
|
||||||
|
\item \verb=Xilinx_SDNet_2018.2_1005_9=
|
||||||
|
\item \verb=Xilinx_Vivado_SDK_2018.2_0614_1954=
|
||||||
|
\end{itemize}
|
||||||
|
|
||||||
|
Both tools need to be installed to /opt/Xilinx/, as paths are
|
||||||
|
hardcoded in various places.

||||||

\section{\label{chapterminus1:thesis}NetFGPA}
|
||||||
|
To be able to compile P4 source code to the NetFPGA the collection of
|
||||||
|
scripts, Makefiles and sample code of P4-NetFGPA is required.
|
||||||
|
|
||||||
|
The repository \url{git@github.com:NetFPGA/P4-NetFPGA-live.git} needs
|
||||||
|
to be cloned to ``projects'' subdirectory as ``P4-NetPFGA''
|
||||||
|
of the user that wants to
|
||||||
|
compile the source code. Access to the repository is granted after
|
||||||
|
applying for access as described on
|
||||||
|
\url{https://github.com/NetFPGA/P4-NetFPGA-public/wiki}.
|
||||||
|
After that the variable \verb=P4_PROJECT_NAME= in
|
||||||
|
\url{~/projects/P4-NetFPGA/tools/settings.sh} needs to be modified to
|
||||||
|
read \verb|export P4_PROJECT_NAME=minip4| instead of
|
||||||
|
\verb|export P4_PROJECT_NAME=switch_calc|.
|
||||||
|
|
||||||
|
Sample code for installation:
|
||||||
|
|
||||||
|
\begin{verbatim}
|
||||||
|
mkdir -p ~/projects
|
||||||
|
git clone git@github.com:NetFPGA/P4-NetFPGA-live.git P4-NetFPGA
|
||||||
|
sed -i 's/\(P4_PROJECT_NAME=\).*/\1minip4/' ~/projects/P4-NetFPGA/tools/settings.sh
|
||||||
|
\end{verbatim}

- Scripts that "fail" (generate wrong data) do exit 0 ->
|
|
||||||
There is no easy / reliable error detection
|
|
||||||
- Writing tables resulted in ioctl errors
|
|
||||||
- Hardware test: unclear if first board was/is broken or not,
|
|
||||||
BUT: second board in different computer allows writing tables
|
|
||||||
- Many scripts depend on each other in later stages, without clear
|
|
||||||
dependencies
|
|
||||||
- There is basically no documentation for someone who "just wants to
|
|
||||||
compile from P4 to netpfga" or A LOT of documentation (if vivado,
|
|
||||||
vhld, sdnet documentation is counted)
|
|

- Very high complexity in toolchain, scripts that are generated

- Scripts that "fail" (generate wrong data) do exit 0 ->
|
||||||
|
There is no easy / reliable error detection
|
||||||
|
- Writing tables resulted in ioctl errors
|
||||||
|
- Hardware test: unclear if first board was/is broken or not,
|
||||||
|
BUT: second board in different computer allows writing tables
|
||||||
|
- Many scripts depend on each other in later stages, without clear
|
||||||
|
dependencies
|
||||||
|
- There is basically no documentation for someone who "just wants to
|
||||||
|
compile from P4 to netpfga" or A LOT of documentation (if vivado,
|
||||||
|
vhld, sdnet documentation is counted)
|
||||||
|
- Very high complexity in toolchain, scripts that are generated
