- * @brief Binary semaphores structures and macros.
- *
- * @addtogroup binary_semaphores
- * @details Binary semaphores related APIs and services.
- *
- * <h2>Operation mode</h2>
- * Binary semaphores are implemented as a set of macros that use the
- * existing counting semaphores primitives. The difference between
- * counting and binary semaphores is that the counter of binary
- * semaphores is not allowed to grow above the value 1. Repeated
- * signal operation are ignored. A binary semaphore can thus have
- * only two defined states:
- * - <b>Taken</b>, when its counter has a value of zero or lower
- * than zero. A negative number represent the number of threads
- * queued on the binary semaphore.
- * - <b>Not taken</b>, when its counter has a value of one.
- * .
- * Binary semaphores are different from mutexes because there is no
- * the concept of ownership, a binary semaphore can be taken by a
- * thread and signaled by another thread or an interrupt handler,
- * mutexes can only be taken and released by the same thread. Another
- * difference is that binary semaphores, unlike mutexes, do not
- * implement the priority inheritance protocol.<br>
- * In order to use the binary semaphores APIs the @p CH_USE_SEMAPHORES
- * option must be enabled in @p chconf.h.

- * Each thread has a mask of pending event flags inside its @p Thread
- * structure.
- * Operations defined for event flags:
- * - <b>Wait</b>, the invoking thread goes to sleep until a certain
- * AND/OR combination of event flags becomes pending.
- * - <b>Clear</b>, a mask of event flags is cleared from the pending
- * events mask, the cleared event flags mask is returned (only the
- * flags that were actually pending and then cleared).
- * - <b>Signal</b>, an event mask is directly ORed to the mask of the
- * signaled thread.
- * - <b>Broadcast</b>, each thread registered on an Event Source is
- * signaled with the event flags specified in its Event Listener.
- * - <b>Dispatch</b>, an events mask is scanned and for each bit set
- * to one an associated handler function is invoked. Bit masks are
- * scanned from bit zero upward.
- * .
- * An Event Source is a special object that can be "broadcasted" by
- * a thread or an interrupt service routine. Broadcasting an Event
- * Source has the effect that all the threads registered on the
- * Event Source will be signaled with an events mask.<br>
- * An unlimited number of Event Sources can exists in a system and
- * each thread can be listening on an unlimited number of
- * them.
- * @pre In order to use the Events APIs the @p CH_USE_EVENTS option must be
- * enabled in @p chconf.h.
- * @post Enabling events requires 1-4 (depending on the architecture)

- * @file chmtx.c
- * @brief Mutexes code.
- *
- * @addtogroup mutexes
- * @details Mutexes related APIs and services.
- *
- * <h2>Operation mode</h2>
- * A mutex is a threads synchronization object that can be in two
- * distinct states:
- * - Not owned (unlocked).
- * - Owned by a thread (locked).
- * .
- * Operations defined for mutexes:
- * - <b>Lock</b>: The mutex is checked, if the mutex is not owned by
- * some other thread then it is associated to the locking thread
- * else the thread is queued on the mutex in a list ordered by
- * priority.
- * - <b>Unlock</b>: The mutex is released by the owner and the highest
- * priority thread waiting in the queue, if any, is resumed and made
- * owner of the mutex.
- * .
- * <h2>Constraints</h2>
- * In ChibiOS/RT the Unlock operations are always performed in
- * lock-reverse order. The unlock API does not even have a parameter,
- * the mutex to unlock is selected from an internal, per-thread, stack
- * of owned mutexes. This both improves the performance and is
- * required for an efficient implementation of the priority
- * inheritance mechanism.
- *
- * <h2>The priority inversion problem</h2>
- * The mutexes in ChibiOS/RT implements the <b>full</b> priority
- * inheritance mechanism in order handle the priority inversion
- * problem.<br>
- * When a thread is queued on a mutex, any thread, directly or
- * indirectly, holding the mutex gains the same priority of the
- * waiting thread (if their priority was not already equal or higher).
- * The mechanism works with any number of nested mutexes and any
- * number of involved threads. The algorithm complexity (worst case)
- * is N with N equal to the number of nested mutexes.
- * @pre In order to use the mutex APIs the @p CH_USE_MUTEXES option
- * must be enabled in @p chconf.h.
- * @post Enabling mutexes requires 5-12 (depending on the architecture)
- * extra bytes in the @p Thread structure.

- *
- * <h2>Operation mode</h2>
- * Semaphores are a flexible synchronization primitive, ChibiOS/RT
- * implements semaphores in their "counting semaphores" variant as
- * defined by Edsger Dijkstra plus several enhancements like:
- * - Wait operation with timeout.
- * - Reset operation.
- * - Atomic wait+signal operation.
- * - Return message from the wait operation (OK, RESET, TIMEOUT).
- * .
- * The binary semaphores variant can be easily implemented using
- * counting semaphores.<br>
- * Operations defined for semaphores:
- * - <b>Signal</b>: The semaphore counter is increased and if the
- * result is non-positive then a waiting thread is removed from
- * the semaphore queue and made ready for execution.
- * - <b>Wait</b>: The semaphore counter is decreased and if the result
- * becomes negative the thread is queued in the semaphore and
- * suspended.
- * - <b>Reset</b>: The semaphore counter is reset to a non-negative
- * value and all the threads in the queue are released.
- * .
- * Semaphores can be used as guards for mutual exclusion zones
- * (note that mutexes are recommended for this kind of use) but
- * also have other uses, queues guards and counters for example.<br>
- * Semaphores usually use a FIFO queuing strategy but it is possible
- * to make them order threads by priority by enabling
- * @p CH_USE_SEMAPHORES_PRIORITY in @p chconf.h.
- * @pre In order to use the semaphore APIs the @p CH_USE_SEMAPHORES
- * option must be enabled in @p chconf.h.
