The CONFIG_FREERTOS_PLACE_FUNCTIONS_INTO_FLASH allows some FreeRTOS functions to be placed
into flash, thus saving some IRAM. However, this feature was previously not supported for
SMP FreeRTOS.
This commit adds CONFIG_FREERTOS_PLACE_FUNCTIONS_INTO_FLASH support for SMP FreeRTOS. There
are now separate linker fragment files for IDF FreeRTOS and SMP FreeRTOS, named "linker.lf"
and "linker_smp.lf" respectively.
The TLSP deletion callback feature is not compatible with the CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP
option. However, the "freertos_options" unit test configuration will enable that option.
This commit disables all CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP related features when compiling with
SMP FreeRTOS.
prvYieldCore() leads to an array-out-of-bounds error when compiled with
-Os optimization and configNUM_CORES = 1. This commit avoids this
compile warning by compiling out the part of code which is unnecessary
when configNUM_CORES is 1.
The Xtensa FreeRTOS port does not save the threadptr register when
doing a voluntary yield. This can result in a crash when multiple
tasks used the threadptr register and call "taskYIELD()".
This commit adds the threadptr register to the solicited stack frame.
This commit makes changes to cpu_ll.h, cpu_hal.h, and interrupt_controller_hal.h:
- Moved to esp_hw_support in order to be deprecated in the future
- HAL/LL API now route their calls to esp_cpu.h functions instead
Also updated soc_hal.h as follows:
- Removed __SOC_HAL_..._OTHER_CORES() macros as they dependend on cpu_hal.h
- Made soc_hal.h and soc_ll.h interfaces always inline, and removed soc_hal.c.
This commit also updates the XCHAL_ERRATUM_572 workaround by
- Removing it's HAL function and invoking the workaround it directly the bootloader
- Added missing workaround for the ESP32-S3
Previously the RV port was routing IDF style critical section API to call FreeRTOS style critical section API.
For example, a call to "portENTER_CRITICAL(mux)" would eventually call `vTaskEnterCritical()" via the following call flow:
- portENTER_CRITICAL(mux)
- vPortEnterCritical()
- portSET_INTERRUPT_MASK_FROM_ISR()
- vTaskEnterCritical()
This commit fixes the IDF style critical section by making sure that they are completely orthogonal to FreeRTOS critical sections
This commit fixes the following build errors in SMP FreeRTOS when building with GCC 11:
- "-Wattributes" warning due to conflicting attributes on xPortInterruptedFromISRContext()
- "-Wtype-limits" warning due to taskVALID_CORE_ID() not casting xCoreID
The behavior of vTaskSuspendAll() has changed in SMP FreeRTOS. This commit
disables scheduler suspension related unit tests for SMP FreeRTOS.
The tests will be updated in IDF-5201
SMP FreeRTOS adds support for dynamic reentrancy in the following commit:
34b8e24d7c
This commit does the following:
- Pulls in the upstream changes
- Move __getreent() to "freertos_tasks_c_additions.h"
- Add the required configNEWLIB_REENTRANT_IS_DYNAMIC to SMP FreeRTOS port
The "Test Queue sets thread safety" tests relied on IDF FreeRTOS specific
scheduling behavior, thus resulting in the test getting stuck when running
with SMP FreeRTOS.
This commit updates and refactors the tests to work on both IDF and SMP FreeRTOS.
This commit fixes how SMP FreeRTOS feeds the INT WDT. Previously, the
port used vApplicationTickHook(). Now, all cores will feed the INT WDT
in xPortSysTickHandler().
This commit moidifies the TWDT as follows:
- Adds a feature to allows subscribing arbitrary users to the TWDT
- Changes esp_task_wdt_init() API to accept configuration structure
- Changes esp_task_wdt_init() and esp_task_wdt_deinit() to subscribe/unsubscribe
idle tasks of various cores.
- Adds support for SMP FreeRTOS idle tasks
- Updates startup code TWDT initialization
- Updates API documentation
