|
|
* Description: Test to verify the behavior of mutex, regular and raw spinlocks
|
|
* acquire and release functions. For this purpose, there are 2 threads
|
|
* involved: the regular main thread, and a worker thread.
|
|
*
|
|
* Test Type: Feature
|
|
*
|
|
* Targets: nvgpu_mutex_init, nvgpu_spinlock_init, nvgpu_raw_spinlock_init,

* Input: @param args [in] Type of lock as defined by TYPE_* macros.
|
|
*
|
|
* Steps:
|
|
* - Initialize the lock using the corresponding init function.
|
|
* - Create a semaphore \a worker_sem and set the \a test_shared_flag to false.
|
|
* - Acquire the lock using its corresponding acquire function.
|
|
* - Create the worker thread and wait for it to signal that it is ready thanks
|
|
* to the \a worker_sem.
|
|
* - The worker thread then blocks trying to acquire the lock.
|
|
* - The main thread then releases the lock and wait for a signal from the
|
|
* worker thread via \a worker_sem.
|
|
* - The worker thread should now be able to acquire the lock and update the
|
|
* \a test_shared_flag.
|
|
* - The main thread ensures that the \a test_shared_flag was updated.
|
|
* - Release and destroy the lock and the worker thread.
