\section{Supported PC hardware%
  \label{supported-pc-hardware}%
}

Barrelfish supports following PC hardware :
%
\begin{quote}
%
\begin{itemize}

\item x86 CPUs in either IA-32 or AMD64 mode. The following are known to work:
%
\begin{itemize}

\item Intel Xeon Clovertown, Gainestown, Beckton (X5355, E5520, X7560, L5520,
L7555)

\item AMD Opteron Santa Rosa, Barcelona, Shanghai, Istanbul, Magny Cours
(2220, 8350, 8374, 8380, 8431, 6174)

\end{itemize}

\end{itemize}

\end{quote}

The biggest compatibility problems are likely to be in the PCI/ACPI code. We
usually discover new quirks (or missing functionality in the ACPI glue code)
on each new machine we test. The following systems are known to work:
%
\begin{quote}
%
\begin{itemize}

\item Intel x5000XVN

\item Tyan n6650W and S4985

\item Supermicro H8QM3-2

\item Dell PowerEdge R610 and R905

\item Sun Fire X2270 and X4440

\item Intel/Quanta QSSC-S4R

\item Lenovo X200 and X301 laptops

\item ASUS Eee PC 1015PEM netbooks

\end{itemize}

\end{quote}

The e1000n driver should work with most recent Intel gigabit ethernet
controllers (see the list in devices/e1000.dev). We've mostly used the
82572EI (PCI device ID 0x1082).

You should also be able to boot Barrelfish on a recent version of QEMU (0.14);
note that the e1000 device emulated by QEMU is not supported by our driver.


\section{Required Tools%
  \label{required-tools}%
}

The following are required to build Barrelfish and its tools:
%
\begin{quote}
%
\begin{itemize}

\item GCC 4.x
%
\begin{itemize}

\item 4.4.5, and 4.5.2 are known to work

\item cross-compiling between i386 and x86\_64 works (requires libc6-dev-i386
to build 32 bit on 64 bit machine)

\item for the ARM port, we recommend the EABI tools available from \href{http://www.codesourcery.com/sgpp/lite/arm}{CodeSourcery}.

\end{itemize}

\item GNU binutils (2.19 is known to work)

\item GNU make

\item GHC v7.4 and Parsec 3.1
- older versions of the tree supported v6.10 or v6.12.2 with Parsec 2.1
- GHC v6.12.1 has a known bug and is unable to build our tools
- earlier versions of GHC are unsupported

\end{itemize}

\end{quote}

Our build system may not be very portable; if in doubt, try building on a
recent Debian or Ubuntu system, as these are what we use.

  \label{building}%

\newcounter{listcnt0}
\begin{list}{\arabic{listcnt0}.}
{
\usecounter{listcnt0}
\setlength{\rightmargin}{\leftmargin}
}

\item Assuming you have already unpacked the sources, create a build directory
%
\begin{quote}{\ttfamily \raggedright \noindent
\$~mkdir~build~\&\&~cd~build
}
\end{quote}
\end{list}

1. Run \texttt{hake.sh}, giving it the path to the source directory and target
architecture(s)
%
\begin{quote}{\ttfamily \raggedright \noindent
\$~../hake/hake.sh~-s~../~-a~x86\_64
}
\end{quote}

This will configure the build directory and use GHC to compile and then run
hake, a tool used to generate the \texttt{Makefile}.

3. Optionally, edit the configuration parameters in \texttt{hake/Config.hs} and
run \texttt{make rehake} to apply them.

\setlength{\rightmargin}{\leftmargin}
}

\item Run make, and wait
%
\begin{quote}{\ttfamily \raggedright \noindent
\$~make
}
\end{quote}

\item If everything worked, you should now be able to run Barrelfish inside QEMU
%
\begin{quote}{\ttfamily \raggedright \noindent
\$~make~sim
}
\end{quote}
\end{list}


\section{Installing and Booting%
  \label{installing-and-booting}%
}

Barrelfish requires a Multiboot-compliant bootloader that is capable of loading
an ELF64 image. At the time of writing, this doesn't include the default GRUB.
Your options are either:
%
\begin{quote}
%
\begin{itemize}

\item use the pre-loader ``elver'' that can be found in the tools directory

\item patch GRUB to support a 64-bit kernel image, using this \href{http://savannah.gnu.org/bugs/?17963}{patch}.

\end{itemize}

\end{quote}

``Installing'' Barrelfish currently consists of copying the ELF files for the CPU
driver and user programs to a location that the target machine can boot from,
and writing a suitable menu.lst file that instructs the bootloader (GRUB) which
programs to load and the arguments to pass them.

If you specify an appropriate INSTALL\_PREFIX, \texttt{make install} will copy the
binaries to the right place for you, eg
%
\begin{quote}{\ttfamily \raggedright \noindent
\$~make~install~INSTALL\_PREFIX=/tftpboot/barrelfish
}
\end{quote}

We usually boot Barrelfish via PXE/TFTP, although loading from a local disk
also works. Instructions for setting up GRUB to do this are beyond the scope of
this document. Assuming you have such a setup, here is a sample menu.lst file
for a basic diskless boot that doesn't do anything useful beyond probing the
PCI buses and starting a basic shell
%

}
\end{quote}

There are many other programs you can load (take a look around the usr tree for
examples). To start a program on a core other than the BSP core, pass
\texttt{core=N} as its first argument.

If things work, you should see output on both the VGA console and COM1.
