This commit backports the following features from FreeRTOS v9.0.0
- uxSemaphoreGetCount()
- vTimerSetTimerId(), xTimerGetPeriod(), xTimerGetExpiryTime()
- xTimerCreateStatic()
- xEventGroupCreateStatic()
- uxSemaphoreGetCount()
Functions backported previously
- xTaskCreateStatic()
- xQueueCreateStatic()
- xSemaphoreCreateBinaryStatic(), xSemaphoreCreateCountingStatic()
- xSemaphoreCreateMutexStatic(), xSemaphoreCreateRecursiveMutexStatic()
- pcQueueGetName()
- vTaskSetThreadLocalStoragePointer()
- pvTaskGetThreadLocalStoragePointer()
Unit tests were also written for the functions above (except for pcQueueGetName
which is tested in a separate Queue Registry MR). The original tlsp and del cb test case
was deleted and integrated into the test cases of this MR.
Previously if multiple tasks had been added to xPendingReadyList for the CPU, only the first one was resumed.
Includes a test case for resuming multiple (pending) tasks on xTaskResumeAll().
Document the limitation that while scheduler is suspended on one CPU, it can't wake tasks on either CPU.
Added documentation about the ESP-IDF changes to FreeRTOS.
The documentation covers changes to the following FreeRTOS aspects.
- Task Creation
- Affects on scheduling (Task skipping, scheduler suspension, tick synchronicity)
- Critical sections and disabling interrupts
- Thread Local Storage Pointers and deletion callbacks
- Configuring ESP-IDF FreeRTOS
