We therefore also reset the --** resume state machine to VC_RESUME_IDLE in this state. --** --** VC_SUSPEND_SUSPENDED - Suspend has completed successfully. Also call --** complete_all on the suspend completion to notify --** anything waiting for suspend to happen. --** --** VC_SUSPEND_REJECTED - Videocore rejected suspend. Videocore will also --** initiate resume, so no need to alter resume state. --** We call complete_all on the suspend completion to notify --** of suspend rejection. --** --** VC_SUSPEND_FAILED - We failed to initiate videocore suspend. We notify the --** suspend completion and reset the resume state machine. --** --** VC_RESUME_IDLE - Initialise the resume completion at the same time. The --** resume completion is in it's 'done' state whenever --** videcore is running. Therfore, the VC_RESUME_IDLE state --** implies that videocore is suspended. --** Hence, any thread which needs to wait until videocore is --** running can wait on this completion - it will only block --** if videocore is suspended. --** --** VC_RESUME_RESUMED - Resume has completed successfully. Videocore is running. --** Call complete_all on the resume completion to unblock --** any threads waiting for resume.

The only exceptions -+ * are creation functions (which might fail due to lack of resources) and functions that -+ * might timeout or fail due to lack of space. Errors that might be reported by the underlying -+ * OS API (e.g. invalid mutex) are treated as a programming error, and are merely asserted on. -+ * -+ * \section thread_synch Threads and synchronisation -+ * -+ * \subsection thread Threads -+ * -+ * The thread API is somewhat different to that found in Nucleus. In particular, threads -+ * cannot just be destroyed at arbitrary times and nor can they merely exit. This is so -+ * that the same API can be implemented across all interesting platforms without too much -+ * difficulty. See vcos_thread.h for details. Thread attributes are configured via -+ * the VCOS_THREAD_ATTR_T structure, found in vcos_thread_attr.h. -+ * -+ * \subsection sema Semaphores -+ * -+ * Counted semaphores (c.f. Nucleus NU_SEMAPHORE) are created with VCOS_SEMAPHORE_T. -+ * Under ThreadX on VideoCore, semaphores are implemented using VideoCore spinlocks, and -+ * so are quite a lot faster than ordinary ThreadX semaphores. See vcos_semaphore.h. -+ * -+ * \subsection mtx Mutexes -+ * -+ * Mutexes are used for locking. Attempts to take a mutex twice, or to unlock it -+ * in a different thread to the one in which it was locked should be expected to fail. -+ * Mutexes are not re-entrant (see vcos_reentrant_mutex.h for a slightly slower -+ * re-entrant mutex). -+ * -+ * \subsection evflags Event flags -+ * -+ * Event flags (the ThreadX name - also known as event groups under Nucleus) provide -+ * 32 flags which can be waited on by multiple clients, and signalled by multiple clients. -+ * A timeout can be specified. See vcos_event_flags.h. An alternative to this is the -+ * VCOS_EVENT_T (see vcos_event.h) which is akin to the Win32 auto-reset event, or a -+ * saturating counted semaphore. -+ * -+ * \subsection event Events -+ * -+ * A VCOS_EVENT_T is a bit like a saturating semaphore. No matter how many times it -+ * is signalled, the waiter will only wake up once. See vcos_event.h. You might think this -+ * is useful if you suspect that the cost of reading the semaphore count (perhaps via a -+ * system call) is expensive on your platform. -+ * -+ * \subsection tls Thread local storage -+ * -+ * Thread local storage is supported using vcos_tls.h. This is emulated on Nucleus -+ * and ThreadX. -+ * -+ * \section int Interrupts -+ * -+ * The legacy LISR/HISR scheme found in Nucleus is supported via the legacy ISR API, -+ * which is also supported on ThreadX. New code should avoid this, and old code should -+ * be migrated away from it, since it is slow. See vcos_legacy_isr.h. -+ * -+ * Registering an interrupt handler, and disabling/restoring interrupts, is handled -+ * using the functions in vcos_isr.h. -+ * -+ */ -+ -+/** -+ * \file vcos.h -+ * -+ * This is the top level header file. Clients include this.
