Function Documentation

◆ TC_MutexAllocation()

void TC_MutexAllocation ( void )

Test mutex object allocation

◆ TC_MutexCheckTimeout()

void TC_MutexCheckTimeout ( void )

Set time thresholds
Create wakeup thread to acquire and release a mutex after 10 ticks
Wait for a mutex with a defined timeout
Check if the mutex is acquired between the minimum and maximum thresholds
Wait for a mutex with an infinite timeout
Check if the mutex is acquired between the minimum and maximum thresholds

◆ TC_MutexNestedAcquire()

void TC_MutexNestedAcquire ( void )

Create a mutex object
Obtain a mutex object
Create a high priority thread that waits for the same mutex
Recursively acquire and release a mutex object
Release a mutex
Verify that every subsequent call released the mutex
Delete a mutex object
Mutex object must be released after each acquisition

◆ TC_MutexOwnership()

void TC_MutexOwnership ( void )

Create a mutex object
Create a child thread and wait until acquires mutex
Create a child thread that tries to release a mutex
Only thread that obtains a mutex can release it.

◆ TC_MutexPrioInherit()

void TC_MutexPrioInherit ( void )

Test mutex prio inherit attribute

◆ TC_MutexPriorityInversion()

void TC_MutexPriorityInversion ( void )

Set priority of the control thread to normal
Create low priority thread, which will acquire mutex
Wait until low priority thread acquires mutex
Raise priority of the control thread
Create high priority thread, which will wait for a mutex
Allow high priority job to wait for mutex
Create medium priority thread
Set priority of the control thread to be the lowest of all
Wait until all jobs finish
Verify thread execution order
Thread execution order must be: Low, High, Medium

◆ TC_MutexRobust()

void TC_MutexRobust ( void )

Test mutex robust attribute

void TC_osMutexNew_3 ( void )

Call osMutexNew to create a mutex object that uses priority inheritance protocol

◆ TC_osMutexNew_4()

void TC_osMutexNew_4 ( void )

Call osMutexNew to create a robust mutex object

◆ TC_osMutexNew_5()

void TC_osMutexNew_5 ( void )

Call osMutexNew to create mutex object and assign a name to it

◆ TC_osMutexNew_6()

void TC_osMutexNew_6 ( void )

Call osMutexNew to create mutex object by specifying memory for control block in attributes

◆ TC_osMutexRelease_1()

void TC_osMutexRelease_1 ( void )

Call osMutexRelease to release acquired mutex
Call osMutexRelease to release mutex that was not acquired
Call osMutexRelease from ISR
Call osMutexRelease with null mutex object
