[Xen-devel] [PATCH 00/18] arm/altp2m: Introducing altp2m to ARM.

[Sergej Proskurin <proskurin@xxxxxxxxxxxxx>]

Hello together,

Since this is my first contribution to the Xen development mailing list, I
would like to shortly introduce myself. My name is Sergej Proskurin. I am a PhD
Student at the Technical University of Munich. My research areas focus on
Virtual Machine Introspection, Hypervisor/OS Security, and Reverse Engineering.

The following patch series can be found on Github[0] and is part of my
contribution to this year's Google Summer of Code (GSoC)[1]. My project is
managed by the organization The Honeynet Project. As part of GSoC, I am being
supervised by the Xen developer Tamas K. Lengyel <tamas@xxxxxxxxxxxxx>, George
D. Webster, and Steven Maresca.

In this patch series, we provide an implementation of the altp2m subsystem for
ARM. Our implementation is based on the altp2m subsystem for x86, providing
additional --alternate-- views on the guest's physical memory by means of the
ARM 2nd stage translation mechanism. The patches introduce new HVMOPs and
extend the p2m subsystem. We extend libxl to support altp2m on ARM and modify
xen-access to test the suggested functionality.
