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.
- Move vTaskStartSchedulerOtherCores()
- implementation to freertos_tasks_c_additions.h
- declaration to freertos_idf_additions_priv.h as API is private
- Rename vTaskStartSchedulerOtherCores() -> prvStartSchedulerOtherCores() to
indicate that the function 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.
- Uncrustified IDF addition related header/source files
- Reorganized functions into groups
- linker_common.lf updated to adhere to new function organization
Previously, Task Snapshot could be conditionally built based on the
CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT option. However, there is no overhead
with always enabling Task Snapshot functions, as the linker will remove any
functions if they are not called.
This commit...
- removes all ESP-IDF dependencies on the CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT
option so that Task Snapshot functions are always available.
- Makes CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT a hidden option to maintain
compatibility with user code.
- adds documentation regarding Task Snapshot.
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.
