The Xen-Troops RPI 5 Xen demonstration project is intended to demonstrate how RPI 5 can be used to run with Xen which includes the following images:
- Zephyr operated control domain which is a thin Zephyr Dom0
zephyr-dom0-xtapplication with shell and SD-card storage support (SDHC). It also supports dom0less functionality. This domain is resposible for Xen domains control. It includes xen-tools library which gives an ability to control other domains. - Linux operated driver domain. This domain managing hardware and provides access to some of this hardware to other domains using PV backends. It has access to USB and rootfs is placed on USB storage.
- A set of domains to be started from the control domain.
- NVME stogage support as DomD rootfs.
Once Zephyr control domain booted it can start other guest domains.
The Zephyr Dom0 zephyr-dom0-xt provides following guest domain configurations:
- rpi_5_domd: The Xen guest domain configuration which uses real RPI5 GPIO HW
/soc/gpio@7d517c00. It's based on Zephyr Blinky sample. - rpi_5_domu: The Xen guest domain configuration which is starts Xen guest domain without using real RPI5 HW. It's based on Zephyr samples/synchronization sample.
- helloworld_xen-arm64: The Xen guest domain configuration without using real RPI5 HW which starts Unikraft kernel. It is based on "Unikraft helloworld" and "monkey" examples.
- linux_pv_domu: The Linux based Xen guest domain with initrams and PV network support.
Boot process:
- RPI5 bootloder started u-boot
- u-boot executes boot script:
- loads Zephyr Dom0 binary
- loads RPI 5 Linux DomU binary for DomU0
- loads Xen Passthrough device tree binary for DomU0
- loads Linux System device tree device tree binary
- applies changes to Linux System device tree device tree for Xen
dom0lessboot mode - loads Xen binary and starts Xen
- Xen is booted and starts Zephyr Dom0 zephyr-dom0-xt and RPI 5 Linux DomU0
Build for the driver domain device is based on RPI5 bsp yocto build: meta-raspberrypi
This is release 0.2.0. This release supports the following features:
- Zephyr operated control domain:
- xen libraries integration that allows control of the other domains.
- domd with running OCI containers as Aos services capability.
- Linux operated driver domain:
- controls hardware;
- provides PV backends for the domains.
- rpi_5_domd domain
- zephyr-based domain built on top of zephyr-blinky sample;
- GPIO device passedthrough to the domain to control onboard LED;
- do not start automatically.
- rpi_5_domu domain
- zephyr-based domain built on top of zephyr-sync sample;
- do not start automatically.
- helloworld_xen-arm64 domain:
- demonstrates work of unikernel images as a domains.
- linux_pv_domu domain:
- Simple linux-based domain with initramfs
- implements PVnet interface to access other domains via pv network;
- impelments PVblock interface which allows to mount block devices to the domains.
- Configuration to use either NVME or USB as a DomD rootfs storage.
Testing pvnet connection instruction: linux_pv_domu testing
Below dependencies have to be satisfied before start building project:
mkdir <my_build_dir>
cd <my_build_dir>
curl -O https://raw.githubusercontent.com/xen-troops/meta-xt-prod-devel-rpi5/master/rpi5.yaml
moulin rpi5.yaml
ninja
The build process generates two images:
- SD-card image to be used for boot and by the Zephyr Dom0
zephyr-dom0-xtapplication; - USB-flash image to be used as rootfs by Linux operated driver domain.
For build system with rootfs domd on nvme storage:
moulin rpi5.yaml --DOMD_ROOT nvme
ninja
ninja full.img
or
ninja full.img.bmap
or
ninja full.img.gz
To flash SD-card image run below command:
sudo dd if=./full.img of=/dev/<sd-dev> bs=4M status=progress
NOTE: Be sure to identify correctly which is usually "sda". For SD-card identification
Plug/unplug SD-card and check /dev/ for devices added/removed.
NOTE: Ensure existing SD-card partitions unmounted if auto-mount is enabled.
The SD-card image full.img is created using GPT format and contains two FATFS partitions:
- First: 512Mb bootfs partition. Contains files required for RPI5 to boot.
- Second: 512MB dom0 partition. Exclusively used by Zephyr Dom0
zephyr-dom0-xtapplication and contains guest domains images.
The bootfs partition content is below. Generic RPI 5 files marked as "RPI5". The Xen-Troops RPI 5 Xen demonstration project files (or modified files) marked as "Xen-Troops:":

To flash USB-flash image run below command:
sudo dd if=./rootfs.img of=/dev/<usb-dev> bs=4M status=progress
NOTE: Be sure to identify correctly which could look like "sdc".
For USB-flash identification Plug/unplug USB-flash and check /dev/ for devices added/removed.
NOTE: Ensure existing USB-flash partitions unmounted if auto-mount is enabled.
It also possible to use generated "ext4" image to flash USB-flash which can be found in relative build folder:
yocto/build-domd/tmp/deploy/images/raspberrypi5/rpi5-image-xt-domd-raspberrypi5.rootfs.ext4
Run below command to flash "ext4" image:
dd if=yocto/build-domd/tmp/deploy/images/raspberrypi5/rpi5-image-xt-domd-raspberrypi5.rootfs.ext4 of=<usb-dev> bs=1M
NOTE: In case of "ext4" image usage the media should be properly partitioned,
for example with fdisk command, before writing "ext4" image.
The USB-flash image content is the RPI 5 Linux rootfs based on RPI5 bsp yocto build meta-raspberrypi with Xen tools enabled.
- Create Sd-card with official Ubuntu from Raspberry foundation.
- Copy file yocto/build-domd/tmp/deploy/images/raspberrypi5/rpi5-image-xt-domd-raspberrypi5.rootfs.ext4 to the USB-Flash dongle.
- Boot from Sd card with Ubuntu. Plug USB-Flash dongle to the Raspberry Pi.
- Create partition on nvme storage with command (should be issued from root account):
(
echo o
echo n
echo p
echo 1
echo
echo +32G
echo w
) | fdisk /dev/nvme0n1
- Flash "ext4" image:
dd if=<usb-dev>/rpi5-image-xt-domd-raspberrypi5.rootfs.ext4 of=/dev/nvme0n1p1 bs=1M
This section shows the way to start domains:
To start domains please execute the following commands from control domain console:
- rpi_5_domd
xu create rpi_5_domd
xu console <domain id>
- rpi_5_domu
xu create rpi_5_domu
xu console <domain id>
- helloworld_xen-arm64
xu create helloworld_xen-arm64
xu console <domain id>
- linux_pv_domu
xu create linux_pv_domu
xu console <domain id>
To switch between control domain and driver domain consoles please press "Ctrl + A" 6 times.
Current domain id can be get by using command:
xstat stat
after starting the domain from control domain console.
The rpi_5_domd mockups Driver Domain (DomD) behavior and uses real
RPI5 GPIO HW /soc/gpio@7d517c00. It's based on Zephyr Blinky sample.
Create DomD by using xu create with rpi_5_domd configuration.
NOTE: Look for the line like "domain:2 created" to get Xen domain id which will be passed to to all subsequent commands.

Destroy domain - DomU Unikraft will be destroyed and Xen domain id "4" will not be accessible any more.
uart:~$ xu destroy 4
domain:4 destroyed
The linux_pv_domu is Xen guest domain (Linux minical) which demonstrates connection of the PVnet and PVblock device
Create DomU Unikraft by using xu create with linux_pv_domu.
NOTE: Look for the line like "domain:5 created" to get Xen domain id which will be passed to to all subsequent commands.
Attach to DomU Unikraft console with xu console <domid>, use Ctrl-']' to exit console.
There should be seen Linux boot log:
uart:~$ xu create linux_pv_domu
uart:~$ xu console 5
Attached to a domain console

The following list shows the list of features already implemented and plans for the future release:
- add support to use nvme storage for DomD rootfs;
- OP-TEE integration enhancements;
- u-boot: fix driver initialization when more than 1 PCIe device enabled;
- add vchan test utilities to the DomD;
- add possibility to configure domains XSM security labels (id) for DomU(s) in the Zephyr Dom0 zephyr-dom0-xt application.
- enable scmi server in ARM-TF and port reset and pinctrl drivers;
- implement pinctrl-scmi protocol server in ARM-TF;
- implementation of the SCMI support in Zephyr for reset;
- integration of the SCMI Mediator support in xen. This will allow different domains to access resources;
- add SCMI-Agent permissions support to ARM-TF and Xen SCMI Mediator;
- backport pinctrl-scmi driver from master to the Raspberry PI 5 Linux kernel;
- configure Linux Kernel (in DomD) to use set resets and pinctrl;
- add wlan support to DomD. This requires SCMI to share pinctrl access.

- Sometime rpi boot firmware files are not deployed during build. In this case rpi-bootfiles, rpi-config and rpi-cmdline recipes should be cleaned with yocto command:
cd yocto
. poky/oe-init-build-env build-domd
bitbake -c clean rpi-bootfiles -c clean rpi-config -c clean rpi-cmdline
cd ../..
