This commit updates how configTHREAD_LOCAL_STORAGE_DELETE_CALLBACKS is defined
by default it to 0 if not defined elsewhere. Dependent code now check for
"configTHREAD_LOCAL_STORAGE_DELETE_CALLBACKS == 1" instead.
This commit synchronize the cosmetic differences of IDF FreeRTOS to upstream
Vanilla v10.4.3. Comsetic differences include:
- Out of date doxygen API descriptions
- Misnamed parameters
- Missing examples
- Fixed/added missing @cond/@code directives
- Extra/missing comments/lines
- Code formatting (uncrustify)
Other changes:
- Some ESP_PLATFORM directives were also removed
- xTaskIncrementTickOtherCores() now depends on "configNUM_CORES > 1"
- Updated some multi-core dummy variable names in FreeRTOS.h
The following changes have been made in this commit:
1. configMINIMAL_STACK_SIZE is now defined as CONFIG_FREERTOS_IDLE_TASK_STACKSIZE.
2. Removed configIDLE_TASK_STACK_SIZE config as it was redundant.
3. Updates the order of allocating the TCB and stack memory to avoid the
stack memory overriding the TCB memory when the stack grows downwards.
4. CONFIG_FREERTOS_IDLE_TASK_STACKSIZE is now incorporated into the
FreeRTOSConfig_smp.h to configure the IDLE0 stack size.
This commit synchronizes multiple functions in tasks.c with upstream v10.4.3
that contain minor differences.
The following functions have had their parameter names or code formatting
updated:
- xTaskCreateStaticPinnedToCore()
- xTaskCreatePinnedToCore()
- prvInitialiseNewTask()
- prvTaskIsTaskSuspended()
- vTaskStartScheduler()
- xTaskResumeAll()
- xTaskCheckForTimeOut()
- uxTaskResetEventItemValue()
The following functions have had their missing "xAlreadyYielded" restored
- xTaskDelayUntil()
- vTaskDelay()
The following functions have had their critical section/interrupt disdable
usage update
- vTaskSuspendAll()
- xTaskGetTickCountFromISR()
- xTaskGetApplicationTaskTagFromISR()
This commit synchronizes multiple functions that contain major differences with
upstream v10.4.3. Multi-core modifications are then reapplied to the function.
Vanilla code uses "pxTCB == pxCurrentTCB" to check whether a task is currently
running. This commit adds the following macros instead.
- taskIS_CURRENTLY_RUNNING()
- taskIS_CURRENTLY_RUNNING_ON_CORE()
The following functions have been updated to use those macros instead.
- eTaskGetState()
- vTaskPrioritySet()
- vTaskResume()
The following functions have been synchronized with upstream v10.4.3.
Multi-core modifications are then reapplied.
- vTaskSuspend()
- vTaskDelete()
- prvGetExpectedIdleTime()

This commit synchronizes the following xTaskRemoveFrom...EventList() with
upstream v10.4.3. Multi-core modifications are then reapplied to the
functions.
The functions updated are:
- xTaskRemoveFromEventList()
- vTaskRemoveFromUnorderedEventList()
The following multi-core macros have been removed as they are no longer
required.
- tskCAN_RUN_HERE()
- taskYIELD_OTHER_CORE()
This commit synchronizes the following vTaskPlaceOnEventList...() with
upstream v10.4.3.
The functions updated are:
- vTaskPlaceOnEventList()
- vTaskPlaceOnUnorderedEventList()
- vTaskPlaceOnEventListRestricted()
The traceTASK_DELAY_UNTIL() macro has also been updated.
This commit reverts the previous "taskENTER_CRTIICAL();" so that the argument
is now provided for better code readability. The names of the spinlocks have
also been updated.
This commit updates various FreeRTOS functions to call the newly added
prvCheckForYield() and prvCheckForYieldUsingPriority() when checking for
yielding. This allows the source code to match upstream more closely.
When a FreeRTOS function unblocks a task, that function will check whether
the unblocked task requires a yield to be called. This is currently done by
having each function individually check if the unblocked task has a higher
priority than the both cores, and yielding the appropriate core.
This commit adds the macros list below to abstract away the yielding checking
procedure. This will allow the code to match upstream more closely.
- prvCheckForYield()
- prvCheckForYieldUsingPriority()
This commit fixes vTaskSuspendAll() and xTaskResumeAll() in the following ways.
- For vTaskSuspendAll()
- Sync function source code with upstream single core version
- Clearly mark IDF additions
- For xTaskResumeAll()
- Sync function source code with upstream single core version
- Clearly mark IDF additions
- Fix bug where cores other than core 0 were allowed to unwind pended ticks
This commit fixes the following issues:
- Clearly mark IDF additions in vTaskStepTick() and xTaskCatchUpTicks()
- Add back vTaskSuspendAll()/xTaskResumeAll() to xTaskCatchUpTicks(). Scheduler
suspension and resumption is required to unwind the pended ticks.
Previously, xTaskIncrementTick() would always trigger a yield (i.e., return pdTRUE)
when called on core 1. This would mean core 1 would call vTaskSwitchContext() on
every tick, leading to uneccesary CPU overhead.
This commit fixes xTaskIncrementTick() in the following ways:
- Clearly mark IDF additions in xTaskIncrementTick()
- Moved esp_vApplicationTickHook() to be called direclty in xPortSysTickHandler() in order to
simplify xTaskIncrementTick().
- Only core 0 calls xTaskIncrementTick() in order to simplify the function's logic. Core 0 is
solely responsible for managing xTickCount and xPendedTicks
- All other cores call xTaskIncrementTickOtherCores() instead which is a simplified version of
xTaskIncrementTick() and handles the following:
- Check if core 0 has unblocked a higher priority task to run
- Check if the current core requires time slicing
- Call vApplicationTickHook()
FreeRTOS synchronization primitives (e.g., queues, eventgroups) use various event lists (i.e., task lists) to track what
tasks are blocked on a current primitive. Usually these event lists are accessed via one of the event lists functions
(such as vTask[PlaceOn|RemoveFrom]UnorderedEventList()), which in turn ensure that the global task list spinlock
(xTaskQueueMutex) is taken when accessing these lists.
However, some functions in event_groups.c manually traverse their event lists. Thus if a tick interrupt occurs on
another core during traversal and that tick interrupt unblocks a task on the event list being traversed, the event list
will be corrupted.
This commit modifies the following event_groups.c functions so that they take the global task list lock before
traversing their event list.
- xEventGroupSetBits()
- vEventGroupDelete()
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
This commit does the following:
- Adds SPDX license identifiers to FreeRTOS sources. Remove those FreeRTOS sources from
the copyright ignore list.
- Update xtensa port files to match FreeRTOS v10.4.3. Added SPDX license identifiers
to the port files.
- Fixed some improperly licensed files
- Removed portbenchmark.h from RISC-V port
This commit updates the handles for the timer, task and event_group
modules to struct type. This matches upstream freertos source.

This issue was earlier fixed in commit 79e74e5d5f
but during migration to newer FreeRTOS release, it got introduced again.
This commit fixes thread safety issues with configASSERT() calls
regarding the value of uxSchedulerSuspended. A false negative
occurs if a context switch to the opposite core occurs in between
the getting the core ID and the assesment.

The previous SMP freertos round robin would skip over tasks when
time slicing. This commit implements a Best Effort Round Robin
where selected tasks are put to the back of the list, thus
makes the time slicing more fair.
- Documentation has been updated accordingly.
- Tidy up vTaskSwitchContext() to match v10.4.3 more
- Increased esp_ipc task stack size to avoid overflow
Closes https://github.com/espressif/esp-idf/issues/7256

3. All port files are now placed in freertos/FreeRTOS-Kernel/portable.
4. All additions/customizations are placed in freertos/esp_additions.
5. All other miscellaneous files (README, License files etc.) are moved to

6. Updated esp-cryptoauthlib to latest commit to resolve FreeRTOS
include dependencies.
