Abstract: Disclosed herein is a method for providing a fair access to a spinlock to one or more cores in a multicore system. The method includes setting, a spinlock variable by the first core of the one or more cores. The setting of the spinlock variable corresponds to changing a cache state of the spinlock variable in a cache of the first core to MODIFIED. Further, the method includes setting a secondary variable by the second core of the one or more cores. The setting of the secondary variable corresponds to changing a cache state of the secondary variable in a cache of the second core to MODIFIED. Furthermore, the method includes releasing, by the first core, the spinlock after performing one or more operations on the critical section of data. Furthermore, the method includes updating, by the first core, the INVALID secondary variable.

Abstract: A method for preventing a task-signal deadlock arising due to contention for a mutex in a real-time operating system (RTOS) includes detecting, by a processing unit, a signal notification sent to a task for execution of a signal handler; identifying, by the processing unit, a mutex to be acquired by the signal handler, when the signal notification is detected; determining whether the identified mutex has been acquired by the task; and utilizing, by the processing unit, an alternative stack for execution of the signal handler, in response to determining that the mutex has been acquired by the task, for preventing a task-signal deadlock during the execution.
