AI Technical Summary
Current technologies face challenges in sharing peripheral devices between multiple hosts with individual root controllers due to complexities and limitations in SR-IOV and MR-IOV implementations, leading to difficulties in combining high-performance SOCs and shared peripheral devices.
A peripheral proxy subsystem is introduced to manage SR-IOV peripheral devices, allowing for the allocation of virtual functions across multiple hosts by mapping physical and virtual functions to endpoints, effectively creating a multi-root I/O virtualization environment without the need for MR-IOV devices or switches.
This solution enables efficient sharing of peripheral devices between multiple hosts, overcoming the limitations of existing SR-IOV and MR-IOV technologies, and facilitates the development of multi-root domains using commonly available SR-IOV devices and non-multi-root aware switches.
