The following updates have been made in this commit:
- The commit places ring buffer code in flash memory by default.
- CONFIG_RINGBUF_PLACE_FUNCTIONS_INTO_FLASH has been removed.
- CONFIG_RINGBUF_IN_IRAM is added and can be used to restore the
previous memory placement.
This commit adds an assert check to xRingbufferReceive() and
xRingbufferReceiveFromISR() functions to prevent them from being used to
retrieve items from an allow-split buffer. Corresponding documentation
has also been updated.
This commit fixes an issue with no-split ring buffers where in the the
buffer did not receive items correctly if the acquire pointer wraps
around before items are sent to it.
ESP_STATIC_ANALYZER_CHECK was added to remove some static analyzer warning about
null pointer dereferences that should never happen, but the logic was wrong.
We return pdFALSE if prvReceiveGeneric was called with any of the input pointers
as NULL, but pvItem2 and xItemSize2 will only be non-null for split buffers.
Closes https://github.com/espressif/esp-idf/issues/14905
This commit fixes a bug in the no-split buffer which could receive an
item prematurely if the space on the buffer is acquired until the buffer
is full. The commit also adds a unit test for this scenario.

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.

* All components which won't build (yet) on Linux are excluded.
This enables switching to Linux in an application without
explicitly setting COMPONENTS to main in the main
CMakeLists.txt.
* ESP Timer provides headers for Linux now
* automatically disabling LWIP in Kconfig if it is not available

Fix false positive in coverity where it thinks memory buffers are freed for
statically created ring buffers, leading to a "USE_AFTER_FREE" warning in
vRingbufferDeleteWithCaps().
This commit adds APIS to create a ring buffer with specific memory caps. The
following APIs have been added:
- xRingbufferGetStaticBuffer()
- xRingbufferCreateWithCaps()
- vRingbufferDeleteWithCaps()
When building on linux/host compilers (e.g., GCC), the compiler may add padding
depending on the size and order of the member types.
This commit fixes the ordering or the StaticRingbuffer_t such that it matches
the internal Ringbuffer_t. The "_Static_assert" is always enabled for all
compilers.
Closes https://github.com/espressif/esp-idf/issues/11726
Ring buffers permit sending items of 0 size where:
- No-split/allow-split buffers will send an item (i.e., header) but the item
will have a 0 sized data section
- Byte buffers will simply return pdTRUE
This commit fixes an incorrect assert w.r.t 0 item size in
xRingbufferSendAcquire() and also adds a note to the API descriptions regarding
0 item sizes. A test case has also been added.
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.
xSemaphoreGive won't be executed in configASSERT and semaphore will stay locked if NDEBUG (idf v5) or CONFIG_FREERTOS_ASSERT_DISABLE (idf v3, v4) are defined.
