Asynchronous copying of data within memory

A non-transitory, computer-readable medium storing instructions operable when executed to cause at least one processor to perform operations comprising:

• during execution of a software application by a processor, receiving, by a copy processor separate from the processor, a request for an asynchronous data copy operation to copy data, wherein the request includes an indication to the copy processor to pass an interrupt to the copy manager upon completion of the asynchronous data copy operation instead of set a completion flag upon completion of the asynchronous data copy operation;
• in response to the request, initiating, by the copy processor, the asynchronous data copy operation;
• continuing execution of the software application by the processor;
• determining, by the copy processor, that the asynchronous data copy operation has completed;
• and
• in response to determining that the asynchronous data copy operation has completed, selectively notifying based on the indication in the request to pass the interrupt to the copy manager upon completion of the asynchronous data copy operation instead of set the completion flag upon completion of the asynchronous data copy operation, by the copy processor, the software application that the asynchronous data copy operation has completed through the interrupt instead of the completion flag.

A system comprising:

• memory for storing data;
• a processor operable to perform first operations comprising:
• executing a software application;
• and
• a copy processor separate from the processor and communicably coupled to the memory and the processor, operable to perform second operations comprising:
• during execution of the software application by the processor, receiving a request for an asynchronous data copy operation to copy data within the memory accessible by the copy processor, wherein the request is received from a copy manager accessible by the software application in a user space of an operating system managing execution of the software application and includes an indication to the copy processor to pass an interrupt to the copy manager upon completion of the asynchronous data copy operation instead of set a completion flag upon completion of the asynchronous data copy operation;
• in response to receiving the request, initiating the asynchronous data copy operation;
• determining that the asynchronous data copy operation has completed;
• and
• in response to determining that the asynchronous data copy operation has completed, selectively notifying, based on the indication in the request to pass an interrupt to the copy manager upon completion of the asynchronous data copy operation instead of set the completion flag upon completion of the asynchronous data copy operation, the software application that the asynchronous data copy operation has completed through the interrupt instead of the completion flag.
