Dual-Android on Nexus 10

on YouTube ↗31m

" summary

Nexus 10 runs two Androids on Xen ARM with 1 GB fixed RAM per VM, Dom0 using pass-through drivers and DomU using a paravirtualized GPU backend that time-slices the Mali T604 and forwards 2–4k GPU packets per frame. Targeting 60 fps, interactive workloads hit near-native rates while GLBench 2.1 (Egypt) peaks around 34 fps GLBenchmark, about 70% of Dom0. Work includes a multi-page ring to batch packets, a PV grant reuse bug, and a 99.4% reliable vsync via the event channel.
