Linux Mutex Implementation at Matthew Fisken blog

Linux Mutex Implementation. Locks a mutex object, which identifies a mutex. Rt_mutex_setprio is only used in. On a preempt_rt kernel spinlock_t is mapped to a separate implementation based on rt_mutex which changes the semantics: Implementation of mutex_lock and mutex_unlock functions located in the kernel/locking/mutex.c source code file. The thread that has locked a mutex becomes its current owner and remains the owner until the same thread has unlocked it. If the mutex is already locked by another thread, the thread waits for the mutex to become available. First of all let's start from the. Pushing parameter, sys call # onto stack generating trap/interrupt to enter kernel jump to appropriate function in kernel verify process passed in valid pointer to mutex. Futexes have the desirable property that they do not require a kernel system call in the common cases of locking or unlocking an. Mutexes are represented by ‘struct mutex’, defined in include/linux/mutex.h and implemented in kernel/locking/mutex.c. The functions implementing the task adjustments are rt_mutex_adjust_prio and rt_mutex_setprio. The mutex object referenced by mutex shall be locked by a call to pthread_mutex_lock () that returns zero or.
