Shared coprocessor framework requirements

Background

Objectives

Requirements

Functional

The framework shall:

• implement a coprocessor resources sharing between different domains
• support number of coprocessor instances 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
• an interface to integrate different scheduling algorithms implementation

Operation environment

• XEN 4.8+
• ARM based SOC
