This page will help those new to aarch64(armv8) get started the foundation model provided by ARM.  
This page will help those new to aarch64 (ARMv8) get started with the Foundation Model provided by ARM.  The F21-20140628-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.


==Download==
== Download the Foundation Model ==
The first step will be to download the Foundation model from ARM, a stage4 root filesystem, and a kernel for use with the file system. In order to download the Foundation model you will need to create a free account with ARM.
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.  
{{admon/note|Note: It is important to use the latest Foundation Model, if you encounter any issues check to see that you have the most recent version. }}
{{admon/warning|IMPORTANT: The Fast Models are not currently supported. }}

==Using the model==
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
 
==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:


Unpack the model
  mkdir ~/aarch64
  mkdir ~/aarch64
  cd ~/aarch64
  cd ~/aarch64
  tar xvzf FM000-KT-00035-r0p8-44rel23.tgz
  tar xvzf FM000-KT-00035-r0p8-52rel06.tgz
 
== Using the Model with an Image ==
 
Using the commands below, download and extract the Aarch64 root filesystem tarball.
 
{{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.}}
 
cd ~/aarch64
wget http://dmarlin.fedorapeople.org/fedora-arm/aarch64/F21-20140628-foundation-v8.tar.xz
tar xvf F21-20140628-foundation-v8.tar.xz
 
{{admon/note|Note: there can be newer images provided at link above.}}
 
=== 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).
 
=== 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 ~/F21-20140628-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:


Rather than using the full path, create an alias for running the Foundation model
telnet 192.168.1.1 5000    # note this is the IP of the model gateway and not the model
alias fv8="~/aarch64/Foundation_v8pkg/Foundation_v8"


== Extract the Root Filesystem ==
{{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.}}


After downloading the rootfs extract it to your '~/armv8' directory:
This is an example log of the model starting, and using telnet to access the console:
cd ~/armv8
tar xvjf f19-stage4-rootfs.tar.bz2


With the kernel, rootfs in your working directory
<pre>
fv8 --image img-foundation.axf --block-device f19-stage4-rootfs.img --network=nat
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
Simulation is started
sh: xterm: command not found
telnet 192.168.1.1 5000


The model will take a few moments to start.


== Using the model with an NFS root ==
$ telnet 192.168.1.1 5000
Trying 192.168.1.1...
Connected to 192.168.1.1.
Escape character is '^]'.
</pre>


Using the model through an NFS is recommended as it will allow the most flexibility when working with the model. Again there are two kernels, one for use with Busybox, the other for use with systemd.  
The model will then start the first stage bootloader (tianocore), which will launch grub2, which will in turn boot the selected kernel, for example:

== Extract ==
EFI stub: Booting Linux Kernel...
First you will need to create a directory for the root filesystem. It is important you use the same path in the example as the kernel expects the rootfs to be at the path noted.  
:
</pre>


mkdir -p /var/exports/aarch64/stage4-nfs-root
You should be able to ssh to the model once it has fully booted.  
cd /var/exports/aarch64/
wget http://fedorapeople.org/groups/armv8/stage4-root-20130411.tar.xz
cd stage4-nfs-root
sudo tar xvJf ../stage4-root-20130411.tar.xz
sudo mv stage4-root-20130411/* .
sudo rm -rf stage4-root-20130411


* Now create an NFS share for the rootfs, edit /etc/exports
{{admon/note|Note: | It may take several minutes for the model to be fully booted.}}
vi /etc/exports
/var/exports/aarch64/stage4-nfs-root *(rw,no_root_squash,no_all_squash,async)


* Start the service
* For ssh login:
  sudo systemctl start nfs.service
  ssh root@192.168.1.5        # note this is the IP address of the model


== Networking with an NFS root ==


You need to setup the network for use with the aarch64 model and the addressing used in the kernel arguments.  
'''Notes:'''
Start the model using one of the following depending on if you would like to use systemd or busybox.  
* Verify that the system date/time are correct.
*Systemd:
* To avoid image or filesystem corruption it is important to shutdown the model properly.
fv8 --image systemd-3.7-nfs-foundation.axf --network=bridged
  shutdown -h now
*Busybox:
* After shutting down, ensure the Foundation Model process has been stopped before restarting.
fv8 --image busybox-3.7-nfs-foundation.axf --network=bridged
  sudo kill -TERM <PID for the Foundation Model process>
After starting the model you will see a new device created on your host system named 'ARM0', use the following to assign an IP address for use with the model:
* The '''root password is 'fedora''''.
sudo ifconfig ARM0 10.0.0.1 netmask 255.255.255.0


Once this adapter is assigned an IP address, the system should boot to either a login prompt or boot with busybox as the init process.

This is pre-release software and not intended for general use.

Aarch64 Quickstart Guide

This page will help those new to aarch64 (ARMv8) get started with the Foundation Model provided by ARM. The F21-20140628-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.

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.

Note: It is important to use the latest Foundation Model, if you encounter any issues check to see that you have the most recent version.
IMPORTANT: The Fast Models are not currently supported.

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

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

Using the Model with an Image

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

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/F21-20140628-foundation-v8.tar.xz
tar xvf F21-20140628-foundation-v8.tar.xz 
Note: there can be newer images provided at link above.

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).

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:
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 ~/F21-20140628-foundation-v8
 ./efi-aarch64.sh
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:
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
Simulation is started
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:

Note:
To navigate the menu use '<ctrl>n' - next and '<ctrl>p' - previous.
