The current ULP RISC-V RTC I2C driver got stuck in an infinite loop if
there is a I2C transaction error. This commit amends the driver flow to
abort the read/write operation if met with errors. It also adds a loop
timeout to avoid getting stuck in an infinite loop.The commit also
updates the default bus timing parameters for RTC I2C to be faster.
This commit also adds documentation help to guide users when they meet
with issues while working with the RTC I2C driver on the ULP RISC-V coprocessor.
esp_efuse_utility_load_efuses_from_flash() read emul_efuse
as an encrypted partition, but that is not correct,
this partition was never encrypted.
Need to read it as not encrypted partition.
Fxed the case: If FE is already on then EFUSE VIRT mode can work with it.

FromISR APIs would put an unblocked task on the pending ready list if
the scheduler is suspended on the current core, irrespective of the
task's core affinity and the state of the scheduler on the other core.
This commit updates this behavior by allowing tasks to get scheduled on
a core which has the scheduler running as long as the task's core
affinity allows it.
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.
This commit replaces the existing TX/RX semaphores with FreeRTOS task event
lists (similar to how FreeRTOS queues implement task blocking). Using task
event lists allows the ring buffer object to be smaller and various ring buffer
functions to be faster. The ring buffer queue set impelementation was also
updated as a result.
This commit updates the ESP-IDF FreeRTOS and FreeRTOS Additions to account for
the fact that there are now two implementations of SMP FreeRTOS (i.e., IDF SMP
vs Amazon SMP).
This commit updates "freertos.rst" to act as an overview document of FreeRTOS
in ESP-IDF, outlining the different FreeRTOS implementations (IDF vs Amazon)
and various supplemental features. The details of each implementation will be
separated to their own documents.
This commit renames "freertos-smp" docuemnt to "freertos_idf". This fits better
with the current dual FreeRTOS implementation (i.e., IDF FreeRTOS and Amazon
SMP FreeRTOS), both of which are SMP capable.
Docs: update CN trans for sleep_modes.rst, misc_system_api.rst, migration_guides/peripherals.rst

List down considerations for the following areas:

This commits adds a internal.md file in the heap directory to clarify the idea behind
which functions is placed in IRAM or in flash.
A section in mem_alloc.rst documentation is added to specify which functions from the
heap component API can be used in interrupt handlers.
esp_hw_support: Adds APIs to define user own MAC addresses without generation from the base MAC address

1. Fix deep sleep wakeup IOs can not be unhold issue
2. Correct hold related APIs' description
3. Fix gpio_force_hold_all API
docs: Add GPIO wakeup source to sleep_modes doc for ESP32C3 and C2
This commit fixes a bug wherein an incorrect bit-width of 0 was being
used while reading the RTC_CNTL_LOW_POWER_ST_REG in ulp_fsm example code
while judging whether the system is ready for wakeup. The correct value
should be a bit-width of 1 to read bit#27 (RTC_CNTL_MAIN_STATE_IDLE) of
the RTC_CNTL_LOW_POWER_ST_REG register on esp32.
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.
Due to poor accuracy the ESP32 ULP TSENS instructions is not recommend for use.
We keep the instruction itself to support users which are already using it,
but should remove it from examples and docs to avoid encouring any new usage of it.
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
docs: updated the RTCIO information for esp32c3 target and added a new example for modem sleep

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.
To make the transition from 32-bit time_t to 64-bit time_t smoother,
detect the size of this type in CMake and remove the manual option in
Kconfig.
The information about 64-bit time_t support is moved from Kconfig help
string into the "system time" section of the API reference.
This commit refactors the FreeRTOS documentation as follows:
- Rewrite FreeRTOS SMP changes document (ESP-IDF FreeRTOS SMP)
- Reorganized sections in kernel behavior changes
- Rewrote descriptions of each kernel behavior changes
- Added notes about using ESP-IDF FreeRTOS for single core targets
- Moved TLSP callback section to FreeRTOS Additions document
- Moved FreeRTOS configuration section to FreeRTOS API document
- Added notes about FreeRTOS applications in ESP-IDF
This commit updates the chip independent system chapters of the
programming guide for esp32s3.

Console example doesn't duplicate code in `console` component.
Linenoise has been improved: it now has a parametrized command line
length. It is now possible to paste data efficiently to the console.
Note: this can only be done if the cursor is at the end of the line.
Closes https://github.com/espressif/esp-idf/issues/7057
The reason timeouts would sometimes happen before the abstime deadline was due
to rounding errors converting the timeout to milliseconds, and also because
vTaskDelay(1) only delays until the next tick which is less than one full tick
period.

Supported a new format of efuse description using '.' in the name.
It means that RD_DIS.KEYx belongs to the range of the RD_DIS name.
RD_DIS, EFUSE_BLK0, 32, 7, Read protection
RD_DIS.KEY0, EFUSE_BLK0, 32, 1, Read protection for EFUSE_BLK4.
RD_DIS.KEY1, EFUSE_BLK0, 33, 1, Read protection for EFUSE_BLK5.
I believe that:
esp_create_default_pthread_config
is a typo (no such function exists), the intention was almost certainly to use:
esp_pthread_get_default_config
Closes https://github.com/espressif/esp-idf/pull/6869/
