Method for handling kernel service request for interrupt routines in multi-core environment and electronic device thereof

A method for handling kernel services for interrupt routines in a multi-core processor of an electronic device, the method comprising:

• receiving an interrupt on a first core of the multi-core processor, wherein the interrupt includes a plurality of kernel service requests and a plurality of non-kernel service requests;
• determining that a worker queue is empty and that a kernel service lock for at least one first kernel service request from the plurality of kernel service requests is available;
• determining that the worker queue is not empty and that a kernel service lock for at least one second kernel service request from the plurality of kernel service requests is unavailable;
• queuing the at least one second kernel service request for which the kernel service lock is unavailable into the worker queue for later execution inside a context-less worker thread;
• and
• executing at least one non-kernel service request and the at least one first kernel service request of the interrupt on the first core of the multi-core processor.

An electronic device for handling kernel services for interrupt routines in a multi-core processor, the electronic device comprising:

• a memory configured to store information about kernel services;
• a multi-core processor comprising a plurality of cores and configured to:
• receive a first interrupt on a first core of the multi-core processor, wherein the first interrupt includes at least one kernel service request and at least one non-kernel service request;
• determine whether a worker queue of the first core of the multi-core processor is empty;
• determine whether a kernel service lock for the at least one kernel service request is acquired by one of the first core or at least one second core of the multi-core processor;
• and
• execute the at least one non-kernel service request of the first interrupt on the first core of the multi-core processor;
• and
• wherein the electronic device is configured to perform one of:
• queue the at least one kernel service request, in response to determining that the worker queue is empty and the kernel service lock for the at least one kernel service request is unavailable, into the worker queue of the first core of the multi-core processor for later execution inside a context-less worker thread;
• or
• queue the at least one kernel service request, in response to determining the worker queue of the first core of the multi-core processor is not empty.
