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
This commit refactors FreeRTOS Kconfig options as follows:
- Grouped them into Kernel and Port submenus
- Renamed Kernel option promppts to match upstream names
- Simplified some option descriptions
- Added "Todo" markers related to SMP support
`vTaskGetSnapshot` is being used in coredump module to collect diagnostic information.
It is possible that input arguments are invalid and `assert` in this situation is not
correct.
This commit modifies API signature to return pdTRUE in case of success, and pdFALSE
otherwise. Caller can verify return value and then take appropriate decision.
This commit updates how the TLS pointers deletion callbacks are called
during task deletion in the FreeRTOS SMP kernel. The callbacks are now
routed through the portCLEAN_UP_TCB() macro. This commit also adds a
new kconfig option CONFIG_FREERTOS_TLSP_DELETION_CALLBACKS to control
the enablement of the TLSP deletion callbacks.
This commit moves the IDF API additions from task.h/task.c to seperate header/source files.
- Declarations moved to "idf_additions.h"
- Definitions moved to "freertos_task_c_additions.h"
The API descriptions have also been updated.
esp_timer will be added as a dependency to freertos only if
CONFIG_FREERTOS_RUN_TIME_STATS_USING_ESP_TIMER is enabled.
Other components are updated to add esp_timer as public or private
dependency, as needed.
This removes esp_timer from the default list of public dependencies.
Some components were including esp_timer.h without declaring a
dependency on esp_timer component. This used to work due to a
transitive public dependency on esp_timer from freertos component.
Add explicit dependencies where needed.
Also some source files were using esp_timer functions without
including the header file. This used to work because esp_timer.h was
included from freertos port header file. This commit adds esp_timer.h
includes where needed.
Moved the following kconfig options out of the target component:
* CONFIG_ESP*_DEFAULT_CPU_FREQ* -> esp_system
* ESP*_REV_MIN -> esp_hw_support
* ESP*_TIME_SYSCALL -> newlib
* ESP*_RTC_* -> esp_hw_support
Where applicable these target specific konfig names were merged into
a single common config, e.g;
CONFIG_ESP*_DEFAULT_CPU_FREQ -> CONFIG_ESP_DEFAULT_CPU_FREQ_MHZ
This commit disables portUSING_MPU_WRAPPERS for the FreeRTOS SMP xtensa port.
This was previously enabled due to the need to keep a CPSA (coprocessor save
area pointer) in the TCB. The CPSA pointer is now calculated at run time.
This commit updates the usage of idle hooks in SMP FreeRTOS as follows:
- IDF style idle hooks are now called from vApplicationMinimalIdleHook()
- If the user provdies their own vApplicationMinimalIdleHook(), it can be
wrapped using -Wl,--wrap if CONFIG_FREERTOS_USE_MINIMAL_IDLE_HOOK is
enabled.
- SMP port no longer uses vApplicationIdleHook() as it's only called from
the prvIdleTask() and not every prvMinimalIdleTask()
This commit updates the task snapshot unit tests as follows:
- Both uxTaskGetSnapshotAll() and vTaskGetSnapshot() are now both tested
- Test cases are now dependent on CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT
This commit updates task snapshot as follows:
- Refactored implementation to increase readability
- Implementation moved into freertos_tasks_c_additions.h
- freertos_tasks_c_additions.h made a private header
- Support SMP FreeRTOS
- Removed configENABLE_TASK_SNAPSHOT option. CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT
is direclty used instead.
IDF FreeRTOS uses vTaskSuspendAll()/xTaskResumeAll() to stop preemption
on a particular core. However, those functions behave differently in FreeRTOS SMP.
This commit replaces all calls of vTaskSuspendAll()/xTaskResumeAll() with
vTaskPreemptionDisable()/vTaskPreemptionEnable() when compiling with SMP FreeRTOS.
This commit fixes various build errors in IDF (and tests) when compiling
with SMP FreeRTOS:
- Updated usage of xTaskGetIdleTaskHandle()
- Disable sysview tracing macros
- Update some task snapshot functions
- Disabled test_freertos_hooks.c test as vApplicationIdleHook() and
vApplicationTickHook() are used.
This commit updates the copied Xtensa port to support the new porting interfaces
of the FreeRTOS SMP kernel. These modifications are mainly contained in
- FreeRTOSConfig.h
- FreeRTOSConfig_smp.h
- portmacro.h
- port.c
Some porting interfaces have changed in FreeRTOS SMP. In order to allow building
with IDF, compatibility interfaces have been added.
