Arbitrating resource acquisition for applications of a multi-processor mobile communications device

A method of operating a concurrency manager client application executed by a second operating system on a second processor system of a multi-processor mobile communications device, the concurrency manager client application interacting with a concurrency manager server application executed by a first operating system that is different from the second operating system on a first processor system of the multi-processor mobile communications device, comprising:

• receiving, by the concurrency manager client application from the concurrency manager server application, priority levels related to access to at least one resource for a first set of applications that execute on the first operating system and a second set of applications that execute on the second operating system, wherein the received priority levels correspond to a set of priority levels determined at the concurrency manager server application and maintained at the concurrency manager server application in a master list that includes a listing of the first and second sets of applications and the set of priority levels, wherein the first and second sets of applications each include a plurality of applications, wherein each resource among the at least one resource is a shared resource that can be accessed by the first and second sets of applications;
• executing, by the concurrency manager server application, a resource arbitration function by which access to each resource among the at least one resource for applications among the first set of applications is autonomously granted or rejected based on the set of priority levels in the master list and based at least in part upon one or more notifications sent by the concurrency manager client application to the concurrency manager server application indicating whether one or more applications among the second set of applications start and/or stop accessing the at least one resource;
• receiving, by the concurrency manager client application in parallel with the resource arbitration function executed by the concurrency manager server application, a request from a first application from among the second set of applications to access a given resource among the at least one resource;
• and
• rejecting, by the concurrency manager client application, the request in response to a notification from the concurrency manager server application indicating that a higher priority application among the first set of applications is currently accessing the given resource, or granting, by the concurrency manager client application, the request based on a determination that no higher priority application among either the first or second sets of applications is currently accessing the given resource.
