\chapter{\label{appendixminus1}Resources and code repositories}
The following sections describe how to acquire the resources
to reproduce the test results. All compilations were made on Ubuntu
16.04 with kernels
\begin{itemize}
\item 4.15.0-54-generic (Supporting Desktop),
\item 4.4.0-143-generic (BMV2 test VM)
\item 4.15.0-55-generic (Desktop with NetFPGA
\end{itemize}
\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 support scripts}
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
\texttt{~/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}
Version \textbf{v1.3.1-46-g97d3aaa} of the P4-NetPFGA repository was
used for creating the bitfiles of this project.
\begin{verbatim}
nico@nsg-System:~/projects/P4-NetFPGA$ git describe --always
v1.3.1-46-g97d3aaa
\end{verbatim}
% ----------------------------------------------------------------------
\chapter{\label{appendix0}BMV2 environment and tests}
All BMV2 based compilations were made with the following compiler:
\begin{verbatim}
p4@ubuntu:~$ p4c --version
p4c 0.5 (SHA: 5ae30ee)
\end{verbatim}
The installation is based on the vagrant files that were provided in
the
``Advanced Topics in
Communication Networks Fall 2018'' course of
ETHZ (\url{https://adv-net.ethz.ch/2018/}) and contains p4tools as
well as all utilities that came with the vagrant installation.
\section{\label{chapter0:bmv2-diff}Diff based checksumming}
For running the diff based checksum code, the following steps are
necessary:
Compiling the p4 code and starting the switch:
\begin{verbatim}
cd ~/master-thesis/p4app
sudo p4run --config nat64-diff.json
\end{verbatim}
Starting the controller which sets up the required table entries:
\begin{verbatim}
cd ~/master-thesis/p4app
sudo python ./controller.py --mode range_router
\end{verbatim}

\subsection{Test 1: IPv4 egress settings work}
Scenario: simple egress port setting for the IPv4 addresses
Step 1: getting correct values for table entries from python:
\begin{verbatim}
>>> int(ipaddress.IPv4Address(u"10.0.0.42"))
167772202
>>> int(ipaddress.IPv4Address(u"10.0.0.4"))

Step 2: setting table netries
\begin{verbatim}

Step 3: setting arp entries

Step 3: generating test packets, expecting 4 packets to show up on
enp2s0f0:

Majority of the log files are stored inside the source code directory
stored at ``netpfga/logs''. It follows a selection of log files
\section{\label{chapterB:netpfga-flasherror}NetFPGA Flash Errors}
Sometimes flashing bitfiles to the NetFPGA will fail. A random amount
of reboots (1 to 3) and a random amount of reflashing will fix this
problem.
Below can be found the log output from the flashing process.

A successful flashing process also emits a couple of errors, however
the message ``fpga configuration failed. DONE PIN is not HIGH'' and
its succeeding lines are missing, as seen below.
After that in all cases a reboot is required; the PCI rescan in no
tested case showed the nf devices.

\section{\label{chapterB:netpfga-nftraffic}NetFPGA misses packets on nf*}
While the nf devices appear in the operating system, packets emitted
by the netpfga cannot be sniffed on the nf interfaces
directly. Instead one has to sniff packets on a physical network card
that is connected to the specific output port.
