- Managing coprocessors for Linux PV domains by running a Xen hypervisor on ARM platforms by Andrii Tseglytskyi 2015-01-14, GlobalLogic
As modern ARM SoCs become faster and faster, they are now capable of performing the same highload tasks that desktop PCs were performing a few years ago, such as HD video playback and highspeed graphic rendering. The structure of an ARM SoC is also now quite complicated. In addition to containing a CPU module or modules, it also includes several peripheral modules (e.g., UARTs, Wireless, HDMI ports, etc.) and coprocessors that are designed to help with highload tasks like Graphic Processor Unit (GPU) or Video Processor Unit (VPU) are assembled together with the main CPU on almost all modern ARM SoCs that are designed for mobile and automotive markets. The article will cover few aspects of sharing such coprocessors when running Xen on embedded SoC.
