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
Closes DOC-4272
See merge request espressif/esp-idf!21617
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.
