Default timeout for interrupt WDT was increased by default
on ESP32, due to some heap integrity check APIs taking a long
time on large PSRAMs and causing timeouts.
But this adjustment was only done for ESP32, not later chips,
even though they may experience the same issue.
Adjusted to have the same behavior on all chips with PSRAM
enabled, making it consistant with the docs.
Closes https://github.com/espressif/esp-idf/issues/18360
Updated the watchdog timer API reference guide to improve explanation
of some existing points.
Also added two new sections in the document:
1. Timeout Stages
2. Common error logs when WDT triggers and possible resolutions
Previously, documentation sections that were only meant for multicore ESP
targets would use tags that depend on CONFIG_FREERTOS_UNICORE or
CONFIG_ESP_SYSTEM_SINGLE_CORE_MODE. This is not ideal as project configuration
can be changed by the user.
This commit updates those tags to use SOC_HP_CPU_HAS_MULTIPLE_CORES which is
always defined in multicore targets regardless of project configuration.
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 updates the watchdog documentation as follows:
- Removes IWDT API reference as it is now considered private API
- Rewrite IWDT section
- Fix headers, types, and formatting
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
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
