This commit fixes the following build errors in SMP FreeRTOS when building with GCC 11:
- "-Wattributes" warning due to conflicting attributes on xPortInterruptedFromISRContext()
- "-Wtype-limits" warning due to taskVALID_CORE_ID() not casting xCoreID
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 fixes how SMP FreeRTOS feeds the INT WDT. Previously, the
port used vApplicationTickHook(). Now, all cores will feed the INT WDT
in xPortSysTickHandler().
This commit moidifies the TWDT as follows:
- Adds a feature to allows subscribing arbitrary users to the TWDT
- Changes esp_task_wdt_init() API to accept configuration structure
- Changes esp_task_wdt_init() and esp_task_wdt_deinit() to subscribe/unsubscribe
idle tasks of various cores.
- Adds support for SMP FreeRTOS idle tasks
- Updates startup code TWDT initialization
- Updates API documentation
This commit updates how the TLS pointers deletion callbacks are called
during task deletion in the FreeRTOS SMP kernel. The callbacks are now
routed through the portCLEAN_UP_TCB() macro. This commit also adds a
new kconfig option CONFIG_FREERTOS_TLSP_DELETION_CALLBACKS to control
the enablement of the TLSP deletion callbacks.
esp_timer will be added as a dependency to freertos only if
CONFIG_FREERTOS_RUN_TIME_STATS_USING_ESP_TIMER is enabled.
Other components are updated to add esp_timer as public or private
dependency, as needed.
This removes esp_timer from the default list of public dependencies.
Moved the following kconfig options out of the target component:
* CONFIG_ESP*_DEFAULT_CPU_FREQ* -> esp_system
* ESP*_REV_MIN -> esp_hw_support
* ESP*_TIME_SYSCALL -> newlib
* ESP*_RTC_* -> esp_hw_support
Where applicable these target specific konfig names were merged into
a single common config, e.g;
CONFIG_ESP*_DEFAULT_CPU_FREQ -> CONFIG_ESP_DEFAULT_CPU_FREQ_MHZ
This commit disables portUSING_MPU_WRAPPERS for the FreeRTOS SMP xtensa port.
This was previously enabled due to the need to keep a CPSA (coprocessor save
area pointer) in the TCB. The CPSA pointer is now calculated at run time.
This commit updates the usage of idle hooks in SMP FreeRTOS as follows:
- IDF style idle hooks are now called from vApplicationMinimalIdleHook()
- If the user provdies their own vApplicationMinimalIdleHook(), it can be
wrapped using -Wl,--wrap if CONFIG_FREERTOS_USE_MINIMAL_IDLE_HOOK is
enabled.
- SMP port no longer uses vApplicationIdleHook() as it's only called from
the prvIdleTask() and not every prvMinimalIdleTask()
This commit updates task snapshot as follows:
- Refactored implementation to increase readability
- Implementation moved into freertos_tasks_c_additions.h
- freertos_tasks_c_additions.h made a private header
- Support SMP FreeRTOS
- Removed configENABLE_TASK_SNAPSHOT option. CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT
is direclty used instead.
This commit updates the copied Xtensa port to support the new porting interfaces
of the FreeRTOS SMP kernel. These modifications are mainly contained in
- FreeRTOSConfig.h
- FreeRTOSConfig_smp.h
- portmacro.h
- port.c
Some porting interfaces have changed in FreeRTOS SMP. In order to allow building
with IDF, compatibility interfaces have been added.
This commit copies over ESP-IDF Xtensa portable files to the
FreeRTOS-Kernel-SMP directory. No changes were made, this commit
only copies the portable source files.
Notes:
- This commit WILL NOT compile
- Some SPDX header dates were updated to pass pre-commit check
