Abstract
A method for handling kernel services for interrupt routines in a multi-core processor in an electronic device. The method comprises receiving 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. The method further determines whether a worker queue of the first core in empty and whether a kernel service lock for the at least one kernel service request is acquired by at least one second core of the multi-core processor, in response to determining that the worker queue of the first core is empty. The method further comprises executing the at least one non-kernel service request of the first interrupt on the first core. The pending kernel service request are queued in the worker queue based on whether worker queue is empty or not and availability of kernel lock.
