XMK Scheduler Interfaces

Kernel [top]

The kernel API provides the minimum set of methods for creating, running, and synchronizing threads. The specifics of the scheduling algorithm are determined by which scheduler option is specified.

	Header File	xmk/kernel.h
	Config Option	USE_XMK_CORE_KERNEL

System Timer [top]

The system timer provides elapsed time since power-up. Time is measured in system ticks.

	Header File	xmk/tmsys.h
	Config Option	USE_XMK_SYSTEM_TIMER

Sleep [top]

The sleep interface provides a system call to allow threads to suspend themselves for a specified amount of time.

	Header File	xmk/sleep.h
	Config Option	USE_XMK_THREAD_SLEEP or USE_XMK_THREAD_XSLEEP

Dynamic Threads [top]

This interface provides methods for dynamically creating and deleting threads once the kernel has been started.

	Header File	xmk/xthread.h
	Config Option	USE_XMK_EXTENDED_THREADS

Enable/Disable Scheduling [top]

This interface provides methods for temporarily disabling context switching of application threads.

	Header File	xmk/sch_eidi.h
	Config Option	USE_XMK_SCHEDULER_EI_DI_SWITCHING

Semaphores [top]

This interface provides counting Semaphores for resource sharing and synchronization between threads.

	Header File	xmk/sema.h
	Config Option	USE_XMK_SEMAPHORES

Mutexes [top]

This interface provides mutual exclusion primitives for protecting shared data structures from concurrent modifications

	Header File	xmk/mutex.h
	Config Option	USE_XMK_MUTEXES

Thread Specific Data [top]

This interface provides a mechanism for the concept of global or static variables that have different values in different threads.

	Header File	xmk/tsd.h
	Config Option	USE_XMK_TSD
