Kernel Object Utilisation View
[Example Tracealyzer Views]
The number of messages present in a queue or semaphore over time.
Kernel objects used for inter-process communication (IPC) include FreeRTOS queues and the various types of semaphore. The number of items in a queue is incremented each time the queue is successfully written to, and decremented each time the queue is successfully read from. In the same way, the count associated with a semaphore is incremented each time the semaphore is successfully ‘given’, and decremented each time the semaphore is successfully ‘taken’. The kernel object utilisation view shows the count associated with a queue or semaphore over a period of time.
The trace view corresponding to the clicked time is displayed when the view is clicked.
