Samsung will present the challenges of creating a dual-Android platform on the Nexus 10 (Cortex A15 based) using Xen on ARM.
Samsung has been endeavoring to run XEN on ARM based mobile devices using para-virtualization for CortexA9 devices earlier and now with virtualization extensions on cortexA15 devices.
The primary end user use case is BYOD(Bring Your Own Device), where two isolated OSs run simultaneously. One OS would be “personal” OS and the other a “work” OS. The user experience should not deteriorate in either of the OSs and GPU is the biggest hurdle in achieving this. Samsung would present its approach in virtualization of the GPU within the context of XEN and discuss the challenges encountered in achieving a good FPS(frames per second) in both OSs (two Androids in this case).
The main points would be stress the following points
* Virtualization on mobile devices and user experience importance for its success.
* GPU virtualization is achievable with very good performance using XEN.
* XEN and open source collaboration from Samsung.
* Paravirtualization cahllenges of IO/peripheral devices on a typical Mobile device with virtualization extension support for CPU and Memory.
