This commit replaces the use of portNUM_PROCESSORS and configNUM_CORES
macros in all of ESP-IDF. These macros are needed to realize an SMP
scenario by fetching the number of active cores FreeRTOS is running on.
Instead, a new Kconfig option, CONFIG_FREERTOS_NUMBER_OF_CORES, has been
added as a proxy for the FreeRTOS config option, configNUMBER_OF_CORES.
This new commit is now used to realize an SMP scenario in various places
in ESP-IDF.
[Sudeep Mohanty: Added new Kconfig option CONFIG_FREERTOS_NUMBER_OF_CORES]

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 updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.
This commit does the following:
- Update existing unit tests that use the TWDT to call the new
esp_task_wdt_init() API
- Add a set of dedicate TWDT unit tests
- Updates the TWDT example
Updated main examples README to add missing examples folders and Getting Started links
Updated wifi/fastscan example README
Updated wifi examples README
Updated wifi main examples README
Added instructions and removed obviousness from examples README
Updates on example README in peripherals, system and wifi
Updates on example README in peripherals and added wave form pictures on wave_gen example
Updates and review on example README
Revision on unit style convention
Added the getting started link for each supported version
Readme review and recommended enhancements
Added the default note on the wave form option info
Added the ESP32-C3 support information on the temperature sensor example README
Added Getting Started information for ESP32-S2 and ESP32-C3
Issue fixed on the supported target on README
Resolved merge conflict
This commit reverts the revert on the new task watchdog API. It also
fixes the following bug which caused the reversion.
- sdkconfig TASK_WDT_TIMEOUT_S has been reverted from the unit of ms back to the
unit of seconds. Fixes bug where projects using the new API without rebuilding sdkconfig
would cause the old default value of 5 to be interpreted in ms.
This commit also adds the following features to the task watchdog
- Updated idle hook registration to be compatible with dual core hooks
- Updated dual core hooks to support deregistration for cpu
- Legacy mode has been removed and esp_task_wdt_feed() is now replaced by
esp_task_wdt_reset(). esp_task_wdt_feed() is deprecated
- Idle hooks to reset are now registered/deregistered when the idle tasks are
added/deleted from the Task Watchdog instead of at Task Watchdog init/deinit
- Updated example
Legacy API of task watchdog used the same function esp_task_wdt_feed() to add
and feed a task. This caused issues of implicitly adding a task to the wdt list
if the function was used in shared code.
The new API introduces init, adding, feeding, deleting, deinit functions. Tasks
must now be explicitly added to the task watchdog using their handles. Deletion
must also be explicit using task handles. This resolves the issue of implicit
task additions to the task watchdog due to shared code calling
esp_task_wdt_feed().
Task watchdog is now fully configurable at runtime by calling the init and
deinit functions.
Also added functions to get the handles of idle tasks of the other core. This
helps when adding idle tasks to the watchdog at run time.
Configuring the task watchdog using menu config is still available, however
menu config will only result in calling the init and add functions for idle
tasks shortly after the scheduler starts.
Menu config also allows for using legacy behavior, however the legacy behavior
willcall the new API functions but with slight variations to make them legacy
compatible.
Documentation and example have also been updated
gcov_rtio.c headers updated to prevent error of freertos header files being
included in the wrong order.
Resolves issue TW#13265
