Shared coprocessor framework requirements

Background

TBD

Objectives

TBD

Requirements

Functional

The framework shall:

• provide a coprocessor resources sharing between different domains
• support a number of coprocessor instances shared between domains in runtime
• support configurable on system startup shareable coprocessors configuration (number of instances, type of instances, scheduling algorithm per coprocessor instance, etc)
• support configurable on domain startup list of coprocessors shared to this particular domain
• support runtime configuration of scheduling algorithm per instance of shared coprocessor

Non-functional

• The framework will provide an interface to integrate different coprocessor support implementation
• The framework will provide an interface to integrate different scheduling algorithms implementation
• (Optional) The coprocessor firmware and drivers should not be changed in order to support the sharing.

Operation environment

• XEN 4.8+

Assumptions and dependencies

• MMU-enabled SoC with MMU-protected coprocessor(s)
