Xen ARM with Virtualization Extensions/Arndale

Jump to navigationJump to search

The work for Xen on the Arndale Development board is on his way. So don't expect to have a usable dom0 yet.

Preparing the board

The bootloader provided with the Arndale does not let Xen boot in hypervisor mode, so we will use the u-boot provided by Linaro.

Follow the step on the Linaro wiki, to build and install u-boot.

Building Xen and Linux

First, will build Linux for dom0, to have a device tree to provide to Xen.

You can get a tree from xenbits which is built on top of Linaro's tree [1].

Use this config file and add anything you need. 

 git clone git://xenbits.xen.org/people/aperard/linux-arndale.git linux
 cd linux
 wget -O .config 'http://xenbits.xen.org/gitweb/?p=people/aperard/linux-arndale.git;a=blob_plain;f=.config;hb=refs/heads/config'
 make uImage
 make dtbs

Use arch/arm/boot/exynos5250-arndale.dtb as a device tree provided to Xen at compile time.

To Build, get the source tree from the repo, which contain branches (last one is exynos5250-2013-03-22) with patches to get serial and other device working on the board. 

 git clone --branch exynos5250-2013-03-22 git://xenbits.xen.org/people/aperard/xen-arm.git

Then, Build Xen on ARM, with CONFIG_DTB_FILE=$linux_tree/arch/arm/boot/exynos5250-arndale.dtb passed to make.
