This commit fixes a bug where if an unpinned task is interrupted by a level 1
ISR that users the FPU, the FPU usage will cause the interrupted task to
become pinned to the current core.
Note: This bug was already fixed in SMP FreeRTOS in commit
d69361779e. This commit simply backports the
fix to IDF FreeRTOS.
This commit refactors the pxPortInitialiseStack() function of the riscv
FreeRTOS ports (both IDF and SMP FreeRTOS).
- Each stack area is now separated into their own functions
- Each function will individually
- Push the stack pointer to allocate the stack area
- Initiaze the allocated stack area
- Each stack area's size and usage is now clearly documented in code
This commit refactors the pxPortInitialiseStack() function of the xtensa
FreeRTOS ports (both IDF and SMP FreeRTOS).

* Added port layer from the FreeRTOS POSIX port, added
additional port code for ESP-IDF.
* Created another hello world example using that POSIX
port in tools/test_apps.
* Removed old linux app
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 multiple functions in queue.c with upstream v10.4.3.
Multi-core modifications are then reapplied to these functions. The following
functions were modified:
prvNotifyQueueSetContainer()
xQueueGenericCreateStatic()
xQueueGenericCreate()
xQueueGetMutexHolder()
xQueueCreateCountingSemaphoreStatic()
xQueueCreateCountingSemaphore()
xQueueGenericSend()
xQueueGenericSendFromISR()
xQueueReceiveFromISR()
uxQueueMessagesWaiting()
prvUnlockQueue()
prvIsQueueFull()
xQueueAddToSet()
xQueueRemoveFromSet()
prvNotifyQueueSetContainer()
Note: The SEGGER_SYSVIEW traceQUEUE_SEND() macro was updated as the
xCopyPosition argument is no longer available in scenarios where the
macro is called.
This commit fixes the function declaration naming from esprv_intc_set_threshold()
to esprv_intc_int_set_threshold(), thus allowing the underlying ROM funciton to be
exposed via the header.
This commit removes the riscv_interrupts.h header is it has become redundant. The previously
exposed API has been handled as follows:
- "riscv_interrupt_enable()" and "riscv_interrupt_disable()" have been removed. These functions
were declarations only and never had any implementation.
- "riscv_global_interrupts_enable()" and "riscv_global_interrupts_disable()" renamed to
"rv_utils_intr_global_enable()" and "rv_utils_intr_global_disable()" respectively and now
placed in rv_utils.h
ESP32-C2 has a single group timer, thus it will use it for the interrupt watchdog,
which is more critical than the task watchdog. The latter is implement in
software thanks to the `esp_timer`component.

functions.
The functions updated are:
- xTaskRemoveFromEventList()
- vTaskRemoveFromUnorderedEventList()
The following multi-core macros have been removed as they are no longer
required.
- tskCAN_RUN_HERE()

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()

The description of how the xTaskGenericNotifyWait parameter is handled in the
xTaskGenericNotifyWait() function was inaccurate.
In this commit, the description was updated to match the implementation of xTaskGenericNotifyWait().
This commit marks all functions in interrupt_controller_hal.h, cpu_ll.h and cpu_hal.h as deprecated.
Users should use functions from esp_cpu.h instead.
This function removes the following legacy atomic CAS functions:
From compare_set.h (file removed):
- compare_and_set_native()
- compare_and_set_extram()
From portmacro.h
- uxPortCompareSet()
- uxPortCompareSetExtram()
Users should call esp_cpu_compare_and_set() instead as this function hides the details
of atomic CAS on internal and external RAM addresses.
Due to the removal of compare_set.h, some missing header includes are also fixed in this commit.
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()
This commit fixes the following:
- Fixes a bug wherein the timer status is active for oneshot timers that
expire before they are started.
- Callback calls for periodic timers where made before the timers were
auto-reloaded.
- Timer expiry trace was being set after the timer callback is called.

Idle tick hook that indicates completion of scheduler init must be launched
on other core than the one where main task runs. Earlier it was assumed that
main task shall always run on PRO cpu but that behavior can be changed with
ESP_MAIN_TASK_AFFINITY_CPU1 and hence this fix.

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()
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.
