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
- add hardware stack guard based on assist-debug module
- enable hardware stack guard by default
- disable hardware stack guard for freertos ci.release test
- refactor rtos_int_enter/rtos_int_exit to change SP register inside them
- fix panic_reason.h header for RISC-V
- update docs to include information about the new feature
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.
xTaskRemoveFromUnorderedEventList is a scheduler internal function, thus will
never be called by users. Therefore, the compatbility define is not necessary.
Vanilla FreeRTOS expects applications to use one of the heap implementations
provided by FreeRTOS (i.e., heap_x.c), where functions such as pvPortMalloc()
and vPortFree() are defined in the heap implementation.
However, ESP-IDF already provides its own heap implementation
(i.e., esp_heap_caps.h). Thus, the pvPortMallc()/vPortFree() functions were
previously overriden by macro to call esp_heap functions directly.
This commit refactors the FreeRTOS port's heap as such:
- Added a heap_idf.c that implements all of the heap related functions required
by FreeRTOS source
- All dynamic memory allocated by FreeRTOS is from internal memory. Thus, the
FreeRTOS heap is the internal memory subset of the ESP-IDF heap.
- Removed some old macros to reduce diff from upstream source code.
Macros that need to reteurn a value should use GCC statement expression macro
syntax. This commit fixes the portTRY_ENTER_CRITICAL() in the RISC-V port of
SMP FreeRTOS to be a statement expression macro.
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 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.
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
