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).

- Initiaze the allocated stack area
- Each stack area's size and usage is now clearly documented in code
* 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 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.

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, 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()
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.

Closes IDFGH-7705
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.
This commit makes changes to cpu_ll.h, cpu_hal.h, and interrupt_controller_hal.h:
- Moved to esp_hw_support in order to be deprecated in the future
- HAL/LL API now route their calls to esp_cpu.h functions instead
Also updated soc_hal.h as follows:
- Removed __SOC_HAL_..._OTHER_CORES() macros as they dependend on cpu_hal.h
- Made soc_hal.h and soc_ll.h interfaces always inline, and removed soc_hal.c.
This commit also updates the XCHAL_ERRATUM_572 workaround by
- Removing it's HAL function and invoking the workaround it directly the bootloader
- Added missing workaround for the ESP32-S3
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
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 updates the visibility of various header files and cleans up
some unnecessary inclusions. Also, this commit removes certain header
include paths which were maintained for backward compatibility.
This commit refactors the FreeRTOS configuration headers as follows:
- Layout is now similar to FreeRTOSConfig.h found in other upstream demos
- Separate out Vanilla FreeRTOS configurations and ESP-IDF additions
- Move/remove some irrelevant/unused macros and configurations
This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.
