Provided is a method for scheduling of tasks for an operating system on a multi-core processor. The method includes receiving a system call for initiating a scheduling operation on a second core and invoking a scheduling instance to the second core, and the scheduling instance notifies the scheduling operation of an incoming high priority task. Further, the method includes deferring a switching context instance at the second core, and the deferring the switching context instance at the second core includes unblocking the first core to perform other tasks.

Apparatus and method for deferral scheduling of tasks for operating system on multi-core processor

A method for handling a relative priority based scheduling procedure in an electronic device. The method includes receiving at least one task, from an application, to access a first core from a plurality of cores in the electronic device. Further, the method includes determining a relative priority with at least one second core from the plurality of cores in the electronic device based on the at least one task. Further, the method includes scheduling the at least one task in the first core from the plurality of cores in the electronic device based on the relative priority.

Method and electronic device for handling relative priority based scheduling procedure

The present disclosure provides method and apparatus for managing kernel services in multi-core system. Embodiments herein provide a method for managing kernel services in a multi-core system. The method includes configuring a lock for a kernel and object-specific locks for shared resources of the kernel and parallel processing IPC services for different shared resources on a plurality of cores of the multi-core system using the object-specific locks.

Method and apparatus for managing kernel services in multi-core system

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.
