Add more information about which GPIOs of ESP32-C3/ESP32-C2/ESP32-H2 can wake up the chip from Deep-sleep mode
Closes DOC-4899

* Added a POSIX/Linux simulator that is compatible with the Amazon
FreeRTOS SMP API. Note that the simulator itself is still
single core, like the IDF FreeRTOS POSIX/Linux simulator.
This commit adds the corresponding CreateWithCaps functions for tasks:
- xTaskCreatePinnedToCoreWithCaps()
- xTaskCreateWithCaps()
- vTaskDeleteWithCaps()
Documentation and migraiton guide have been updated accordingly.
Closes https://github.com/espressif/esp-idf/issues/11216
- Remove the size limit for the hash_map array from the CONFIG_HEAP_TRACE_HASH_MAP_SIZE
- Add test case for heap tracing using hashmap
- Update heap_debug.rst to document the newly added configurations in the heap component
Closes https://github.com/espressif/esp-idf/issues/11172
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.
Closes https://github.com/espressif/esp-idf/issues/10929
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:
- Hardware security
- Network security
- Product security
Also added brief explanation about "Security Policy" for ESP-IDF.
Closes IDF-1565
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

The sections details that only 160KB of DRAM can be used for statically allocated data.
Reference this new section in mem_alloc.rst and memory-types.rst.
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.
