Abstract:
A method of resource allocation failure recovery is disclosed. The method generally includes steps (A) to (E). Step (A) may generate a plurality of resource requests from a plurality of driver modules to a manager module executed by a processor. Step (B) may generate a plurality of first calls from the manager module to a plurality of allocation modules in response to the resource requests. Step (C) may allocate a plurality of resources to the driver modules using the allocation modules in response to the first calls. Step (D) may allocate a portion of a memory pool to a particular recovery packet using the manager module in response to the allocation modules signaling a failed allocation of a particular one of the resources. Step (E) may recover from the failed allocation using the particular recovery packet.
