This commit adds beta support for the FreeRTOS v10.5.1 kernel which can be
enabled by enabling the CONFIG_FREERTOS_USE_KERNEL_10_5_1 option.
The following changes have been made:
- Updated freertos/CMakeLists.txt to build v10.5.1 kernel with v10.4.3. ports
- Updated existing Xtensa and RISC-V ports to work with V10.5.1
- Modifications to other ESP-IDF components to work with v10.5.1
- Added some ESP-IDF specific tracing changes to v10.5.1 kernel
- Make CONFIG_FREERTOS_USE_KERNEL_10_5_1 a public option
Note: The beta release is missing some minor fixes, performance improvements,
and features. Using this beta release for production is not recommended.

This commit moves/merges the IDF FreeRTOS "PinnedToCore" task creation
functions from tasks.c/task.h to idf_additions.h/freertos_task_c_additions.h.
Also updated FreeRTOS Mock component to provide mocks for "idf_additions.h"
headers for our mock tests.
A weak xTimerCreateTimerTask() was added to tasks.c as a workaround in ESP-IDF
in order to prevent timers.c from being linked when unused.
This commit moves that workaround to `freertos_tasks_c_additions.h`
The following application hook protoypes are defined in task.h from FreeRTOS
V10.4.0 onwwards and no longer need to be declared in tasks.c, thus have been
removed:
- vApplicationStackOverflowHook()
- vApplicationTickHook()
- vApplicationGetIdleTaskMemory()
This function moves ulTaskNotifyTake()/xTaskNotifyWait() from IDF FreeRTOS
`tasks.c` to `freertos_compatibility.c`. These functions were kept for
pre-compiled library compatibilty. Move them reduces the kernel source code
difference when compared to upstream FreeRTOS.
This commit combines various task utility API additions in IDF FreeRTOS and with
their Amazon SMP FreeRTOS addition counterparts. The folloiwng functions have
been moved to freertos_tasks_c_additions.h and idf_additions.h as these API
are considered public:
- xTaskGetCurrentTaskHandleForCPU()
- xTaskGetIdleTaskHandleForCPU()
- xTaskGetAffinity()
- pxTaskGetStackStart()
Also fixed in missing #if macros when vTaskCoreAffinityGet() is called in
Amazon SMP FreerTOS tests.
This commit moves xTaskIncrementTickOtherCores() to freertos_tasks_c_additions.h
and freertos_idf_additions_priv.h (as API is private). This reduces the code
differences cmpared to upstream FreeRTOS.
- The following IDF API additions are moved to freertos_tasks_c_additions.h
(implementation) and freertos_idf_additions_priv.h (declaration) as APIs are
private. This reduces the source code difference from upstream.
- prvENTER_CRITICAL_OR_SUSPEND_ALL()
- prvEXIT_CRITICAL_OR_RESUME_ALL()
- prvENTER_CRITICAL_OR_MASK_ISR()
- prvEXIT_CRITICAL_OR_UNMASK_ISR()
- vTaskTakeKernelLock()
- vTaskReleaseKernelLock()
- Rename vTask[Take/Release]KernelLock() to prv[Take/Release]KernelLock() to
indicate that the this API is private.
This commit adds an implicit inclusion of `idf_additions.h` to `FreeRTOS.h` in
preparation for moving some IDf specific API to `idf_additions.h`.
This implict inclusion allows existing code to be continue using these
relocated APIs without any changes in header inclusions.
Also removed "#pragma once" directive from "freertos_tasks_c_additions.h" since
that header is included as a source file.
Fixed an undiscovered bug with prvENTER_CRITICAL_OR_MASK_ISR() and
prvEXIT_CRITICAL_OR_MASK_ISR() where the `uxInterruptStatus` argument was not
used.
However, all calls of this macro provide a local `uxSavedInterruptStatus`
variable, leading to this bug being hidden.
This commit updates the xPortCanYield() for esp32p4 by correcting the
return condition. Previously, the API would return true if an ISR of
priority 1 was received which is incorrect.
Previously, TLSP deletion callbacks were...
- Stored in a seprate TCB member "pvThreadLocalStoragePointersDelCallback"
- Called separately via multipole prvDeleteTLS() insertions in tasks.c
This commit refactors how TLSP deletion callbacks are stored and called:
- TLSP deletion callbacks are now stored in "pvThreadLocalStoragePointers"
directly. configNUM_THREAD_LOCAL_STORAGE_POINTERS is doubled in size so that
the deletion callbacks are stored in the latter half of the array
- The callbacks are now called via "portCLEAN_UP_TCB()". As such, the
prvDeleteTLS() additions are no longer needed and the function can be removed
- Removed some legacy TLSP tests using the old method of storing the callback
pointers.
This commit reduces the source code diff between IDF FreeRTOS and upstream
vanilla FreeRTOS, in preparation for v10.5.1 upgrade.
portCLEAN_UP_COPROC() was an IDF specific addition to FreeRTOS, where the
macro was called from prvDeleteTCB() to clean up the coprocessor context of a
deleted task.
This commit removes portCLEAN_UP_COPROC(). The coprocessor cleanup routine
(i.e., vPortCleanUpCoprocArea()) is now called via portCLEAN_UP_TCB()->
vPortTCBPreDeleteHook().
This removes a minor code difference between IDF FreeRTOS and upstream.
Previously, if CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP was enabled, users
would provide a definition for a vPortCleanUpTCB() hook function that is called
right before a task's memory is freed in prvDeleteTCB(). However,
vPortCleanUpTCB() will be reclaimed by ESP-IDF for internal use in v6.0.
This commit introduces the following changes...
Introduced a new CONFIG_FREERTOS_TASK_PRE_DELETION_HOOK option:
- Provides the same pre-deletion hook functionality. But users now define
vTaskPreDeletionHook() instead.
- CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP still exists, but is marked as
deprecated. This is to maintain compatibility with existing applications
that already define vPortCleanUpTCB().
- Removed redundant --wl --wrap workaround with vPortCleanUpTCB()
- Added todo notes to remove support for user defined vPortCleanUpTCB()
completely in v6.0.
- Updated test cases to use new CONFIG_FREERTOS_TASK_PRE_DELETION_HOOK option
Freed up portCLEAN_UP_TCB() to call a new internal vPortTCBPreDeleteHook():
- vPortTCBPreDeleteHook() now replaces the previous "wrapped" implementation
of vPortCleanUpTCB().
- vPortTCBPreDeleteHook() is an internal task pre-delete hook for IDF FreeRTOS
ports to inject some pre-deletion operations.
- Internal pre-delete hook now invokes user provided vTaskPreDeletionHook()
if enabled.
- Relocated vPortTCBPreDeleteHook() to correct section in port.c
This commit optimizes xTaskRemoveFromEventList() by removing the
listLIST_IS_EMPTY() check from single core builds. The scenario of the event
list being empty when the function is called can only occur on multi-core
builds.
This commit fixes and optimizes vTaskRemoveFromUnorderedEventList() in the
following ways:
- Fixed bug in single core builds where the unblocked task would be placed on
xPendingReadyList.
- If an ISR occurs while accessing xPendingReadyList, and the ISR also
accesses the xPendingReadyList, xPendingReadyList would be corrupted.
- In single core builds, this function is only called from event groups with
the scheduler suspended. Thus the function should have exclusive access to
pxReadyTasksLists instead of xPendingReadyList.
- The function's single core logic has now been updated to match upstream
behavior, by always placing the unblocked task on pxReadyTasksLists.
- Optimized the function for single core builds by removing the
taskCAN_BE_SCHEDULED() check.
- In single core builds, given that the function is always called with the
scheduler suspended
- Thus, the taskCAN_BE_SCHEDULED (and the subsequent routine to place the
unblocked task on the xPendingReadyList) is not necessary for single core
builds.
- The function now matches upstream behavior in single core builds.

freertos: Updated vTaskRemoveFromUnorderedEventList() to consider scheduler state before adding task to ready list
Closes IDF-5785
See merge request espressif/esp-idf!23482
vTaskRemoveFromUnorderedEventList() runs under the assumption that the
scheduler is suspended during the call. However, for IDF FreeRTOS, this
is not true. When dual-core system is active, this API call is made in
a critical section but without suspending the scheduler. This commit
updates the vTaskRemoveFromUnorderedEventList() function to now consider
the scheduler state on either cores before adding a task to the ready list.
This commit fixes a bug in xTaskRemoveFromEvenetList() where in the
check for scheduler suspension did not account for nested suspensions.
Additionally, this commit updates all checks for scheduler
suspension to follow a uniform way.
* Added a POSIX/Linux simulator that is compatible with the Amazon
FreeRTOS SMP API. Note that the simulator itself is still
single core, like the IDF FreeRTOS POSIX/Linux simulator.
When porting an RTOS to the Xtensa architecture, there are a few files that
are common to all Xtensa RTOS ports. These files form the Xtensa RTOS porting
layer (e.g., "xtensa_vectors.S", "xtensa_context.S"). An Xtensa RTOS port is
expected to provide an RTOS specific "xtensa_rtos.h" header to interface with
the Xtensa RTOS porting layer.
Previously, the Xtensa RTOS porting layer files were placed in the FreeRTOS
component. This commit does the following:
1. Moves the Xtensa RTOS porting layer files from the `freertos` component to
the `xtensa` component. The following files were moved:
- xtensa_asm_utils.h
- xtensa_context.S
- xtensa_loadstore_handler.S
- xtensa_vectors.S
2. Refactored xtensa component include paths to separate Xtensa RTOS porting
layer headers.
- Xtensa HAL headers included via `#include <xtensa/...h>`
- Xtensa RTOS porting layer headers included via `#include <...h>`
Note: The xtensa files in the Amazon SMP FreeRTOS port are not moved/deleted in
this commit to ensure the moved files retain a clean diff history.
This commit merges the "FreeRTOSConfig_smp.h" file into the "FreeRTOSConfig.h".
The configurations for all FreeRTOS implementations are now stored in a single
file.
FromISR APIs would put an unblocked task on the pending ready list if
the scheduler is suspended on the current core, irrespective of the
task's core affinity and the state of the scheduler on the other core.
This commit updates this behavior by allowing tasks to get scheduled on
a core which has the scheduler running as long as the task's core
affinity allows it.
The default implementation of some xtensa vectors were previously moved to
"xtensa_vector_defaults.S" as weak functions so that they could be overriden.
This commit moves these default vectors back into "xtensa_vectors.S" in
preparation for further refactoring of the xtensa component.
