How fast is Xen on ARM, really?

With Xen on ARM getting out of the early preview phase and becoming more mature, it is time to run a few benchmarks to check that the design choices paid out, the architecture is sound and the code base is solid. It is time to find out how much is the overhead introduced by Xen [...]

Mirage v2.0: a recap of the new features

The first release of Mirage back in December 2013 introduced the prototype of the unikernel concept, which realised the promise of a safe, flexible mechanism to build highly optimized software stacks purpose-built for deployment in the public cloud (more background on this). Since then, we've been hard at work using and extending Mirage for real projects and the community has been steadily growing. We're thrilled to announce the release of Mirage OS v2.0 today! Over the past few weeks the team has been hard at work blogging about all the new features in this latest release, coordinated by the tireless...

Building an ARMy of Xen unikernels

Mirage has just gained the ability to compile unikernels for the Xen/arm32 platform, allowing Mirage guests to run under the Xen hypervisor on ARM devices such as the Cubieboard 2 and CubieTruck. Introduction The ARMv7 architecture introduced the (optional) Virtualization Extensions, providing hardware support for running virtual machines on ARM devices, and Xen's ARM Hypervisor uses this to support hardware accelerated ARM guests. Mini-OS is a tiny OS kernel designed specifically for running under Xen. It provides code to initialise the CPU, display messages on the console, allocate memory (malloc), and not much else. It is used as the low-level core of Mirage's Xen implementation. Mirage...

sunxi-tools now available in Debian

I've recently packaged the sunxi tools for Debian. These are a set of tools produce by the Linux Sunxi project for working with the Allwinner "sunxi" family of processors. See the package page for details. Thanks to Steve McIntyre for sponsoring the initial upload. The most interesting component of the package are the tools for working with the Allwinner processors' FEL mode. This is a low-level processor mode which implements a simple USB protocol allowing for initial programming of the device and recovery which can be entered on boot (usually be pressing a special 'FEL button' somewhere on the device). It is thanks to FEL mode that most sunxi based devices are pretty much...
