This page will help those new to aarch64(armv8) get started with the Foundation Model provided by ARM. There are a number of options available when using the model, including use of a disk image file or NFS root filesystem, as well as a choice of kernel if you would like to use Systemd or Busybox as the init process.

This page will help those new to aarch64 (ARMv8) get started with the Foundation Model provided by ARM. The F21-20140407-foundation-v8 Remix tarball provides an F21-based disk image, which boots the kernel from the image using UEFI(Tianocore) and Grub2, and a sample script for starting the model. This Fedora Remix uses a look aside repository for the kernel package, which includes patches that are headed upstream, but not yet added to Fedora.

==== Kernel Packages ====

{{admon/note|Note: The extracted disk image requires approximately 12GB disk space. Please ensure you have adequate free space. This may take several minutes to unpack, depending on your hardware.}}
The Foundation model seems to have some performance issues when using a serial console, there are two kernel packages to choose from - one that includes the console, the other does not and is intended for use by connecting through ssh. The kernels use the wrapper to set the hostname and networking. For example 'systemd-3.9-image-2G-1.axf' will set a hostname of 'model-1' with and IP address of 10.0.1.2, the default gw should be set to 10.0.1.1. The last number in the kernel name indicates which network, hostname will be used when it boots.  
+
* With console:
+
<pre>
+
wget http://fedorapeople.org/~pwhalen/aarch64/systemd-3.9-image-2G.tar.bz2
+
tar xvjf systemd-3.9-image-2G.tar.bz2
+
</pre>
+
* No console:
+
<pre>
+
wget http://fedorapeople.org/~pwhalen/aarch64/systemd-3.9-image-ns-2G.tar.bz2
+
tar xvjf systemd-3.9-image-ns-2G.tar.bz2
+
</pre>
+
  
===== Starting the Model =====
+
cd ~/aarch64
NOTE: You may need to adjust your path for the model depending on the version in use.
+
wget http://dmarlin.fedorapeople.org/fedora-arm/aarch64/F21-20140407-foundation-v8.tar.xz
* With console:
+
tar xvf F21-20140407-foundation-v8.tar.xz
<pre>
+
sudo Foundation_v8pkg/models/Linux64_GCC-4.1/Foundation_v8 \
+
--image systemd-3.9-image-2G/systemd-3.9-image-2G-1.axf \
+
--network=bridged \
+
--network-bridge=ARM1 \
+
--block-device stage4-root-20130725.img 
+
</pre>
+
* No console:
+
<pre>
+
sudo Foundation_v8pkg/models/Linux64_GCC-4.1/Foundation_v8 \
+
--image systemd-3.9-image-ns-2G/systemd-3.9-image-ns-2G-1.axf \
+
--network=bridged \
+
--network-bridge=ARM1 \
+
--block-device stage4-root-20130725.img 
+
</pre>
+
 
+
On the host immediately after launching the model:
+
 
+
sudo ifconfig ARM1 10.0.1.1 netmask 255.255.255.0
+
  
You should now be able to ssh to the model once it has fully booted. If you're using the console enabled kernels you can use telnet to connect to the serial console using the provided ports as it boots, this will also close the xterm popup window.
+
=== Allowing the Model to Connect to the Internet ===
* For console:
+
telnet 10.0.1.1 5003 # note this is the IP of the gateway and not the model
+
The port number seems to be inconsistent and can vary depending on how quickly you attempt to connect, but is usually the last listed port.
+
* No console (also works on console)
+
ssh root@10.0.1.2 # note this is the IP address of the model
+
The '''root password is 'fedora', there is also another account called 'builder' password 'builder''''.
+
 
+
== Using the model with an NFS root ==
+
 
+
Using the model through an NFS root is no longer recommended or supported here.

 +
=== Starting the Model ===
 +
 +
The kernel supports virtio, so the kernel image and initramfs included on the image will be used in the boot process.  This image boots using UEFI (tianocore) and Grub2.
 +
 +
An example script for starting the model has been included in the tarball.  This script performs the following steps to start the model:
 +
 +
<pre>
 +
sudo ../Foundation_v8pkg/models/Linux64_GCC-4.1/Foundation_v8 \
 +
  --cores=1 \
 +
  --visualization \
 +
  --image=linux-system-el3-foundation.axf \
 +
  --data=RTSM_VE_FOUNDATIONV8_EFI.fd@0xA0000000 \
 +
  --block-device `pwd`/${IMAGE} \
 +
  --network=bridged \
 +
  --network-bridge=ARM1 &
 +
sleep 5
 +
sudo ifconfig ARM1 192.168.1.1 netmask 255.255.255.0
 +
</pre>
 +
{{admon/note|Note: |  Depending on your environment you may need to change the IP addressing used.}}
 +
 +
To start the model, change to the image subdirectory and run the script:
 +
 +
  cd ~/F21-20140407-foundation-v8
 +
  ./efi-aarch64.sh
 +
 +
{{admon/note|Note: | You must have 'sudo' access in order to run this script. The script assumes the foundation model is in:
 +
    ~/aarch64/Foundation_v8pkg
 +
Adjust as necessary for your environment.}}
 +
 +
To connect to the serial console, telnet to the provided ports as it boots, for example:
 +
 +
telnet 192.168.1.1 5000    # note this is the IP of the model gateway and not the model
 +
 +
{{admon/note|Note: |  Connecting using telnet will also close the xterm popup window. | If your connection is not successful using port 5000, try 5001, 5002, or 5003.}}
 +
 +
This is an example log of the model starting, and using telnet to access the console:
 +
 +
<pre>
 +

 +
terminal_1: Listening for serial connection on port 5001
 +

[edit] Aarch64 Quickstart Guide

This page will help those new to aarch64 (ARMv8) get started with the Foundation Model provided by ARM. The F21-20140407-foundation-v8 Remix tarball provides an F21-based disk image, which boots the kernel from the image using UEFI(Tianocore) and Grub2, and a sample script for starting the model. This Fedora Remix uses a look aside repository for the kernel package, which includes patches that are headed upstream, but not yet added to Fedora.

[edit] Download the Foundation Model

The first step is to download the Foundation model from ARM. The model is not re-distributable and will therefore require you to create a free account with ARM. Once completed, you will be able to download the Foundation Model and begin.

To run the model you may need to install some additional software with the following command:

sudo yum install xterm xorg-x11-fonts-{misc,100dpi,75dpi}* telnet bridge-utils

[edit] Extract the Foundation Model

Once you have downloaded the model, you will need to set up your environment. The model can be extracted to a path of your choosing. Your home directory will be used in this example.

Unpack the model:

mkdir ~/aarch64
cd ~/aarch64
tar xvzf FM000-KT-00035-r0p8-52rel06.tgz

[edit] Using the Model with an Image

Using the commands below, download and extract the Aarch64 root filesystem tarball.

Note.png
Note: The extracted disk image requires approximately 12GB disk space. Please ensure you have adequate free space. This may take several minutes to unpack, depending on your hardware.
cd ~/aarch64
wget http://dmarlin.fedorapeople.org/fedora-arm/aarch64/F21-20140407-foundation-v8.tar.xz
tar xvf F21-20140407-foundation-v8.tar.xz 

[edit] Allowing the Model to Connect to the Internet

On the host:

  • Enable IP forwarding (as root)
echo 1 > /proc/sys/net/ipv4/ip_forward
  • Set up Network Address Translation:
HOSTEXTERNAL=eth0 # Replace this with your outside interface
sudo iptables -t nat -I POSTROUTING -o $HOSTEXTERNAL -j MASQUERADE
sudo iptables -I FORWARD -i $HOSTEXTERNAL -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
sudo iptables -I FORWARD -i ARM1 -o $HOSTEXTERNAL -j ACCEPT
  • Firewall trouble? Try this:
sudo iptables -I INPUT -i ARM1 -j ACCEPT

The model uses Google's Public DNS server (8.8.8.8) for name resolution (/etc/resolv.conf).

[edit] Starting the Model

The kernel supports virtio, so the kernel image and initramfs included on the image will be used in the boot process. This image boots using UEFI (tianocore) and Grub2.

An example script for starting the model has been included in the tarball. This script performs the following steps to start the model:

sudo ../Foundation_v8pkg/models/Linux64_GCC-4.1/Foundation_v8 \
  --cores=1 \
  --visualization \
  --image=linux-system-el3-foundation.axf \
  --data=RTSM_VE_FOUNDATIONV8_EFI.fd@0xA0000000 \
  --block-device `pwd`/${IMAGE} \
  --network=bridged \
  --network-bridge=ARM1 &
sleep 5
sudo ifconfig ARM1 192.168.1.1 netmask 255.255.255.0
Note.png
Note:
Depending on your environment you may need to change the IP addressing used.

To start the model, change to the image subdirectory and run the script:

 cd ~/F21-20140407-foundation-v8
 ./efi-aarch64.sh
Note.png
Note:
You must have 'sudo' access in order to run this script. The script assumes the foundation model is in:
   ~/aarch64/Foundation_v8pkg
Adjust as necessary for your environment.

To connect to the serial console, telnet to the provided ports as it boots, for example:

telnet 192.168.1.1 5000     # note this is the IP of the model gateway and not the model
Note.png
Note:
Connecting using telnet will also close the xterm popup window.

This is an example log of the model starting, and using telnet to access the console:

terminal_0: Listening for serial connection on port 5000
terminal_1: Listening for serial connection on port 5001
terminal_2: Listening for serial connection on port 5002
terminal_3: Listening for serial connection on port 5003
Visualization web server started on port 2001

sh: xterm: command not found
 
telnet 192.168.1.1 5000


$ telnet 192.168.1.1 5000
Trying 192.168.1.1...
Connected to 192.168.1.1.
Escape character is '^]'.

The model will then start the first stage bootloader (tianocore), which will launch grub2, which will in turn boot the selected kernel, for example:
