- * \brief Simple preemptive multitasking scheduler.
- *
- * Preemption is explicitly regulated at the exit of each interrupt service
- * routine (ISR). Each task obtains a time quantum as soon as it is scheduled
- * on the CPU and its quantum is decremented at each clock tick. The frequency
- * of the timer determines the system tick granularity and CONFIG_KERN_QUANTUM
- * the time sharing interval.
- *
- * When the quantum expires the handler proc_needPreempt() checks if the
- * preemption is enabled and in this case preempt_schedule() is called, that
- * possibly replaces the current running thread with a different one.
- *
- * The preemption can be disabled or enabled via proc_forbid() and
- * proc_permit() primitives. This is implemented using a global atomic counter.
- * When the counter is greater than 0 the task cannot be preempted; only when
- * the counter reaches 0 the task can be preempted again.
- *
- * Preemption-disabled sections may be nested. The preemption will be
- * re-enabled when the outermost preemption-disabled section completes.
- *
- * The voluntary preemption still happens via proc_switch() or proc_yield().
- * The first one assumes the current process has been already added to a
- * private wait queue (e.g., on a semaphore or a signal), while the second one
- * takes care of adding the process into the ready queue.
- *
- * Context switch is done by CPU-dependent support routines. In case of a
- * voluntary preemption the context switch routine must take care of
- * saving/restoring only the callee-save registers (the voluntary-preemption is
- * actually a function call). The kernel-preemption always happens inside a
- * signal/interrupt context and it must take care of saving all registers. For
- * this, in the entry point of each ISR the caller-save registers must be
- * saved. In the ISR exit point, if the context switch must happen, we switch
- * to user-context and call the same voluntary context switch routine that take
- * care of saving/restoring also the callee-save registers. On resume from the
- * switch, the interrupt exit point moves back to interrupt-context, resumes
- * the caller-save registers (saved in the ISR entry point) and return from the
- * interrupt-context.
- *
- * \note Thread priority (if enabled by CONFIG_KERN_PRI) defines the order in
- * the \p proc_ready_list and the capability to deschedule a running process. A
- * low-priority thread can't preempt a high-priority thread.
- *
- * A high-priority process can preempt a low-priority process immediately (it
- * will be descheduled and replaced in the interrupt exit point). Processes
- * running at the same priority can be descheduled when they expire the time
- * quantum.
- *
- * \note Sleeping while preemption is disabled fallbacks to a busy-wait sleep.
- * Voluntary preemption when preemption is disabled raises a kernel bug.
