Mar 10, 2018 · 所谓的i2c总线协议的软件模拟实现方法，就是用软件控制gpio的输入、输出和高低电平变化，来模拟i2c总线通讯过程中scl、sda的电平变化来实现的。.

We missed a spin_lock_init() in ath9k_wmi_event_tasklet() when the wmi event is WMI_TXSTATUS_EVENTID. Placing this init here instead of ath9k_init_wmi() is fine mainly because we need this spinlock when the event is WMI_TXSTATUS_EVENTID and hence it should be initialized when it.

Generate the skeleton for the task named 2-sched-spin and browse the contents of the sched-spin.c file. Compile the source code and load the module, according the above info: ( make build and make copy) Notice that it is waiting for 5 seconds until the insertion order is complete. Unload the kernel module.

Spin_lock_init - produces initialization of the given spinlock; spin_lock - acquires given spinlock; spin_lock_bh - disables software interrupts and acquire given spinlock; spin_lock_irqsave and spin_lock_irq - disable interrupts on local processor and preserve/not preserve previous interrupt state in the flags.

Pthread_spin_lock() - QNX.
The aim of this series is to provide easy and practical examples that anyone can understand. This is the Spinlock in Linux Kernel Part 1 – Linux Device Driver Tutorial Part 23. You can also read mutex , read-write spinlock, seqlock, interrupts, Procfs , Workqueue , Completion , Softirq, and threaded IRQ in the Linux device driver. Prerequisites. To do the latter, the patches: 1. move the sess_cmd_lock to tcm_qla2xxx since it was the only driver using the sess_cmd_list. 2. makes the execution lock/list per cpu'ish. I just allocate nr_cpu_ids's worth of lock/lists then make sure we complete the cmd on the cpu it was started on. With the patches I'm seeing a 25% improvement in IOPs for.

Pthread_spin_init() Initialize a thread spinlock. Synopsis: #include <pthread.h> int pthread_spin_init( pthread_spinlock_t * spinner, int pshared); Arguments: spinner A pointer to the pthread_spinlock_t object that you want to initialize. pshared The value that you want to use for the process-shared attribute of the spinlock.

Other Spin Lock Methods. The method spin_lock_init() can be used to initialize a dynamically created spin lock (a spinlock_t that you do not have a direct reference to, just a pointer). The method spin_trylock() attempts to obtain the given spin lock. If the lock is contended, rather than spin and wait for the lock to be released, the function. Locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Signed-off-by: Ingo Molnar <mingo@xxxxxxx> Signed-off-by: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx>. Void spin_lock_init(spinlock_t *lock); Before entering a critical section, your code must obtain the requisite lock with: void spin_lock(spinlock_t *lock); Note that all spinlock waits are, by their nature, uninterruptible. Once you call spin_lock, you will spin until the lock becomes available. To release a lock that you have obtained, pass it to.
Spin Locks.
Void spin_lock_init(spinlock_t *lock) Initializes given spinlock int spin_trylock(spinlock_t *lock) Tries to acquire specified lock; returns nonzero if lock is currently held and zero otherwise int spin_is_locked(spinlock_t *lock) Returns nonzero if lock is currently held and zero otherwise Table 6.4 Linux Spinlocks. The pthread_spin_lock() function locks the thread spinlock specified by spinner. If spinner isn't immediately available, pthread_spin_lock() blocks until spinner can be locked. If a thread attempts to lock a spinlock that's already locked via pthread_spin_lock() or pthread_spin_trylock(), the thread returns EDEADLK. Returns: EOK Success. EAGAIN. Spin lock & Semaphore • Semaphore: - When init value is 1, it can be a mutex lock to prevent compromise of critical section, just like spin lock. - Different from spin lock, thread goes sleep for waiting lock when failed to get the lock.

The results are undefined if pthread_spin_init () is called specifying an already initialized spin lock. The results are undefined if a spin lock is used without first being initialized. If the pthread_spin_init () function fails, the lock is not initialized and the contents of lock are undefined. Only the object referenced by lock can be used. Real-Time Linux with PREEMPT_RT.
