* An event group is a collection of bits to which an application can assign a
* meaning. For example, an application may create an event group to convey
* the status of various CAN bus related events in which bit 0 might mean "A CAN
* message has been received and is ready for processing", bit 1 might mean "The
* application has queued a message that is ready for sending onto the CAN
* network", and bit 2 might mean "It is time to send a SYNC message onto the
* CAN network" etc. A task can then test the bit values to see which events
* are active, and optionally enter the Blocked state to wait for a specified
* bit or a group of specified bits to be active. To continue the CAN bus
* example, a CAN controlling task can enter the Blocked state (and therefore
* not consume any processing time) until either bit 0, bit 1 or bit 2 are
* active, at which time the bit that was actually active would inform the task
* which action it had to take (process a received message, send a message, or
* send a SYNC).
*
* The event groups implementation contains intelligence to avoid race
* conditions that would otherwise occur were an application to use a simple
* variable for the same purpose. This is particularly important with respect
* to when a bit within an event group is to be cleared, and when bits have to
* be set and then tested atomically - as is the case where event groups are
* used to create a synchronisation point between multiple tasks (a
* 'rendezvous').

* A version of xEventGroupClearBits() that can be called from an interrupt.
*
* Setting bits in an event group is not a deterministic operation because there
* are an unknown number of tasks that may be waiting for the bit or bits being
* set. FreeRTOS does not allow nondeterministic operations to be performed
* while interrupts are disabled, so protects event groups that are accessed
* from tasks by suspending the scheduler rather than disabling interrupts. As
* a result event groups cannot be accessed directly from an interrupt service
* routine. Therefore xEventGroupClearBitsFromISR() sends a message to the
* timer task to have the clear operation performed in the context of the timer
* task.
*
* @note If this function returns pdPASS then the timer task is ready to run
* and a portYIELD_FROM_ISR(pdTRUE) should be executed to perform the needed
* clear on the event group. This behavior is different from
* xEventGroupSetBitsFromISR because the parameter xHigherPriorityTaskWoken is
* not present.
*
* @param xEventGroup The event group in which the bits are to be cleared.
*
* @param uxBitsToClear A bitwise value that indicates the bit or bits to clear.

* and bit 0 set uxBitsToClear to 0x09.
*
* @return If the request to execute the function was posted successfully then
* pdPASS is returned, otherwise pdFALSE is returned. pdFALSE will be returned

*
* A version of xEventGroupSetBits() that can be called from an interrupt.
*
* Setting bits in an event group is not a deterministic operation because there
* are an unknown number of tasks that may be waiting for the bit or bits being
* set. FreeRTOS does not allow nondeterministic operations to be performed in
* interrupts or from critical sections. Therefore xEventGroupSetBitsFromISR()
* sends a message to the timer task to have the set operation performed in the
* context of the timer task - where a scheduler lock is used in place of a
* critical section.
*
* @param xEventGroup The event group in which the bits are to be set.
*
* @param uxBitsToSet A bitwise value that indicates the bit or bits to set.
* For example, to set bit 3 only, set uxBitsToSet to 0x08. To set bit 3
* and bit 0 set uxBitsToSet to 0x09.
*
* @param pxHigherPriorityTaskWoken As mentioned above, calling this function
* will result in a message being sent to the timer daemon task. If the
* priority of the timer daemon task is higher than the priority of the
* currently running task (the task the interrupt interrupted) then
* *pxHigherPriorityTaskWoken will be set to pdTRUE by
* xEventGroupSetBitsFromISR(), indicating that a context switch should be
* requested before the interrupt exits. For that reason
* *pxHigherPriorityTaskWoken must be initialised to pdFALSE. See the
* example code below.
*
* @return If the request to execute the function was posted successfully then
* pdPASS is returned, otherwise pdFALSE is returned. pdFALSE will be returned
* if the timer service queue was full.
*
* Example usage:
* @code{c}
* #define BIT_0 ( 1 << 0 )
* #define BIT_4 ( 1 << 4 )
*
* // An event group which it is assumed has already been created by a call to

* This is the list implementation used by the scheduler. While it is tailored
* heavily for the schedulers needs, it is also available for use by
* application code.
*
* list_ts can only store pointers to list_item_ts. Each ListItem_t contains a
* numeric value (xItemValue). Most of the time the lists are sorted in
* ascending item value order.
*
* Lists are created already containing one list item. The value of this
* item is the maximum possible that can be stored, it is therefore always at
* the end of the list and acts as a marker. The list member pxHead always
* points to this marker - even though it is at the tail of the list. This
* is because the tail contains a wrap back pointer to the true head of
* the list.
*
* In addition to it's value, each list item contains a pointer to the next
* item in the list (pxNext), a pointer to the list it is in (pxContainer)
* and a pointer to back to the object that contains it. These later two
* pointers are included for efficiency of list manipulation. There is
* effectively a two way link between the object containing the list item and
* the list item itself.

* Message buffers build functionality on top of FreeRTOS stream buffers.
* Whereas stream buffers are used to send a continuous stream of data from one
* task or interrupt to another, message buffers are used to send variable
* length discrete messages from one task or interrupt to another. Their
* implementation is light weight, making them particularly suited for interrupt
* to task and core to core communication scenarios.
*
* ***NOTE***: Uniquely among FreeRTOS objects, the stream buffer
* implementation (so also the message buffer implementation, as message buffers
* are built on top of stream buffers) assumes there is only one task or
* interrupt that will write to the buffer (the writer), and only one task or
* interrupt that will read from the buffer (the reader). It is safe for the
* writer and reader to be different tasks or interrupts, but, unlike other
* FreeRTOS objects, it is not safe to have multiple different writers or
* multiple different readers. If there are to be multiple different writers
* then the application writer must place each call to a writing API function
* (such as xMessageBufferSend()) inside a critical section and set the send
* block time to 0. Likewise, if there are to be multiple different readers
* then the application writer must place each call to a reading API function
* (such as xMessageBufferRead()) inside a critical section and set the receive
* timeout to 0.
*
* Message buffers hold variable length messages. To enable that, when a
* message is written to the message buffer an additional sizeof( size_t ) bytes
* are also written to store the message's length (that happens internally, with
* the API function). sizeof( size_t ) is typically 4 bytes on a 32-bit
* architecture, so writing a 10 byte message to a message buffer on a 32-bit
* architecture will actually reduce the available space in the message buffer
* by 14 bytes (10 byte are used by the message, and 4 bytes to hold the length
* of the message).

* will set *pxHigherPriorityTaskWoken to pdTRUE. If
* xMessageBufferSendFromISR() sets this value to pdTRUE, then normally a
* context switch should be performed before the interrupt is exited. This will

*
* Receives a discrete message from a message buffer. Messages can be of
* variable length and are copied out of the buffer.
*
* ***NOTE***: Uniquely among FreeRTOS objects, the stream buffer
* implementation (so also the message buffer implementation, as message buffers
* are built on top of stream buffers) assumes there is only one task or
* interrupt that will write to the buffer (the writer), and only one task or
* interrupt that will read from the buffer (the reader). It is safe for the
* writer and reader to be different tasks or interrupts, but, unlike other
* FreeRTOS objects, it is not safe to have multiple different writers or
* multiple different readers. If there are to be multiple different writers
* then the application writer must place each call to a writing API function
* (such as xMessageBufferSend()) inside a critical section and set the send
* block time to 0. Likewise, if there are to be multiple different readers
* then the application writer must place each call to a reading API function
* (such as xMessageBufferRead()) inside a critical section and set the receive
* block time to 0.
*
* Use xMessageBufferReceive() to read from a message buffer from a task. Use
* xMessageBufferReceiveFromISR() to read from a message buffer from an
* interrupt service routine (ISR).
*
* @param xMessageBuffer The handle of the message buffer from which a message
* is being received.
*
* @param pvRxData A pointer to the buffer into which the received message is
* to be copied.
*
* @param xBufferLengthBytes The length of the buffer pointed to by the pvRxData
* parameter. This sets the maximum length of the message that can be received.
* If xBufferLengthBytes is too small to hold the next message then the message
* will be left in the message buffer and 0 will be returned.
*
* @param xTicksToWait The maximum amount of time the task should remain in the
* Blocked state to wait for a message, should the message buffer be empty.
* xMessageBufferReceive() will return immediately if xTicksToWait is zero and
* the message buffer is empty. The block time is specified in tick periods, so
* the absolute time it represents is dependent on the tick frequency. The
* macro pdMS_TO_TICKS() can be used to convert a time specified in milliseconds
* into a time specified in ticks. Setting xTicksToWait to portMAX_DELAY will
* cause the task to wait indefinitely (without timing out), provided
* INCLUDE_vTaskSuspend is set to 1 in FreeRTOSConfig.h. Tasks do not use any
* CPU time when they are in the Blocked state.
*
* @return The length, in bytes, of the message read from the message buffer, if
* any. If xMessageBufferReceive() times out before a message became available
* then zero is returned. If the length of the message is greater than
* xBufferLengthBytes then the message will be left in the message buffer and
* zero is returned.
*
* Example use:
* @code{c}
* void vAFunction( MessageBuffer_t xMessageBuffer )
* {
* uint8_t ucRxData[ 20 ];
* size_t xReceivedBytes;
* const TickType_t xBlockTime = pdMS_TO_TICKS( 20 );
*
* // Receive the next message from the message buffer. Wait in the Blocked
* // state (so not using any CPU processing time) for a maximum of 100ms for
* // a message to become available.
* xReceivedBytes = xMessageBufferReceive( xMessageBuffer,
* ( void * ) ucRxData,
* sizeof( ucRxData ),

*
* @param pxHigherPriorityTaskWoken It is possible that a message buffer will
* have a task blocked on it waiting for space to become available. Calling
* xMessageBufferReceiveFromISR() can make space available, and so cause a task
* that is waiting for space to leave the Blocked state. If calling
* xMessageBufferReceiveFromISR() causes a task to leave the Blocked state, and
* the unblocked task has a priority higher than the currently executing task
* (the task that was interrupted), then, internally,
* xMessageBufferReceiveFromISR() will set *pxHigherPriorityTaskWoken to pdTRUE.
* If xMessageBufferReceiveFromISR() sets this value to pdTRUE, then normally a
* context switch should be performed before the interrupt is exited. That will
* ensure the interrupt returns directly to the highest priority Ready state
* task. *pxHigherPriorityTaskWoken should be set to pdFALSE before it is
* passed into the function. See the code example below for an example.
*
* @return The length, in bytes, of the message read from the message buffer, if

* Interrupt safe version of the API function that sends a stream of bytes to
* the stream buffer.
*
* ***NOTE***: Uniquely among FreeRTOS objects, the stream buffer
* implementation (so also the message buffer implementation, as message buffers
* are built on top of stream buffers) assumes there is only one task or
* interrupt that will write to the buffer (the writer), and only one task or
* interrupt that will read from the buffer (the reader). It is safe for the
* writer and reader to be different tasks or interrupts, but, unlike other
* FreeRTOS objects, it is not safe to have multiple different writers or
* multiple different readers. If there are to be multiple different writers
* then the application writer must place each call to a writing API function
* (such as xStreamBufferSend()) inside a critical section and set the send
* block time to 0. Likewise, if there are to be multiple different readers
* then the application writer must place each call to a reading API function
* (such as xStreamBufferReceive()) inside a critical section and set the receive
* block time to 0.
*
* Use xStreamBufferSend() to write to a stream buffer from a task. Use
* xStreamBufferSendFromISR() to write to a stream buffer from an interrupt
* service routine (ISR).
*
* @param xStreamBuffer The handle of the stream buffer to which a stream is
* being sent.
*
* @param pvTxData A pointer to the data that is to be copied into the stream
* buffer.
*
* @param xDataLengthBytes The maximum number of bytes to copy from pvTxData
* into the stream buffer.
*
* @param pxHigherPriorityTaskWoken It is possible that a stream buffer will
* have a task blocked on it waiting for data. Calling
* xStreamBufferSendFromISR() can make data available, and so cause a task that
* was waiting for data to leave the Blocked state. If calling
* xStreamBufferSendFromISR() causes a task to leave the Blocked state, and the
* unblocked task has a priority higher than the currently executing task (the
* task that was interrupted), then, internally, xStreamBufferSendFromISR()
* will set *pxHigherPriorityTaskWoken to pdTRUE. If
* xStreamBufferSendFromISR() sets this value to pdTRUE, then normally a
* context switch should be performed before the interrupt is exited. This will
* ensure that the interrupt returns directly to the highest priority Ready
* state task. *pxHigherPriorityTaskWoken should be set to pdFALSE before it
* is passed into the function. See the example code below for an example.
*
* @return The number of bytes actually written to the stream buffer, which will
* be less than xDataLengthBytes if the stream buffer didn't have enough free
* space for all the bytes to be written.
*
* Example use:
* @code{c}
* // A stream buffer that has already been created.
* StreamBufferHandle_t xStreamBuffer;
*
* void vAnInterruptServiceRoutine( void )
* {
* size_t xBytesSent;

*
* if( xBytesSent != strlen( pcStringToSend ) )
* {
* // There was not enough free space in the stream buffer for the entire
* // string to be written, ut xBytesSent bytes were written.
* }
*
* // If xHigherPriorityTaskWoken was set to pdTRUE inside
* // xStreamBufferSendFromISR() then a task that has a priority above the
* // priority of the currently executing task was unblocked and a context
* // switch should be performed to ensure the ISR returns to the unblocked

* 3) Calling an API function from within a critical section or when
* the scheduler is suspended, or calling an API function that does
* not end in "FromISR" from an interrupt.
* 4) Using a queue or semaphore before it has been initialised or
* before the scheduler has been started (are interrupts firing
* before vTaskStartScheduler() has been called?).
* 5) If the FreeRTOS port supports interrupt nesting then ensure that

* The FreeRTOS kernel's RISC-V port is split between the the code that is

*
* + The code that is common to all RISC-V chips is implemented in
* FreeRTOS\Source\portable\GCC\RISC-V-RV32\portASM.S. There is only one
* portASM.S file because the same file is used no matter which RISC-V chip is
* in use.

* + The code that tailors the kernel's RISC-V port to a specific RISC-V
* chip is implemented in freertos_risc_v_chip_specific_extensions.h. There
* is one freertos_risc_v_chip_specific_extensions.h that can be used with any
* RISC-V chip that both includes a standard CLINT and does not add to the
* base set of RISC-V registers. There are additional

* that do not include a standard CLINT or do add to the base set of RISC-V
* registers.
*

* freertos_risc_v_chip_specific_extensions.h HEADER FILE FOR THE CHIP
* IN USE. To include the correct freertos_risc_v_chip_specific_extensions.h

- Updated logic to determine whether sleep is possible in SMP by checking the status of both cores.
- `prvCheckTasksWaitingTermination()`
- Updated logic so that we don't delete tasks on `xTasksWaitingTermination` which are still currently running on the other core.
- `xTaskGetCurrentTaskHandle()`
- In SMP, the function will now disables interrupts to ensure that the calling task does not switch cores while fetching the current core's TCB.
- `xTaskGetSchedulerState()`
- In SMP, the function now disables interrupts to ensure that the calling task does not switch cores while checking its own copy of `uxSchedulerSuspended`.
- `prvAddCurrentTaskToDelayedList()`
- Added extra check to see if current blocking task has already been deleted by the other core.

- Extended critical section so that SMP can check for yields while still inside critical section
- `vTaskStepTick()`
- Extended critical section so that SMP can access `xTickCount` while still inside critical section
## Header File & Doxygen Changes
List of changes made to Vanilla FreeRTOS V10.5.1 header files to allow for building in ESP-IDF documentation build system.
- Removed leading header name line (e.g., `xxx.h`) in doxygen comment blocks. For example:
```c
/**
* xxx.h
*
* Documentation from some func
*/
void some_func(void);
```
- Removed leading `@code{c}` blocks in containing redundant function prototypes. For example:
```c
/**
* @code{c}
* void some_func(int var_a, int var_b);
* @endcode
*
* Documentation from some func
*/
void some_func(int var_a, int var_b);
```
- Added `/** @cond !DOC_EXCLUDE_HEADER_SECTION */` and `/** @endcond */` labels to exclude various doxygen sections from being included into documentation builds. These excluded sections include:
- In doxygen blocks that describe multiple related set of functions/macros, only the function/macro that matches the doxygen blocks parameters is included. For example:
```c
/**
* Description that covers both some_func() and some_func_extra()
*
* @param var_a var_a description
* @param var_b var_b description
*/
/** @cond !DOC_EXCLUDE_HEADER_SECTION */
#define some_func(var_a) #define some_func_generic(var_a, NULL)
/** @endcond */
#define some_func_extra(var_a, var_b) #define some_func_generic(var_a, var_b)
```
- In functions/macros that are not meant to be directly called by users (i.e., internal), such as the various `Generic` variants of functions
- Some types/functions/macros are manually documented, thus are documented with regular comment blocks (i.e., `/* */`) instead of doxygen comment blocks (i.e., `/** */`). Some of these blocks are changed into doxygen blocks.

* The macro's crQUEUE_SEND_FROM_ISR() and crQUEUE_RECEIVE_FROM_ISR() are the

* pvBuffer.
*
* @param pxCoRoutineWoken A co-routine may be blocked waiting for space to become

@ -10,7 +10,7 @@ Overview
The original FreeRTOS (hereinafter referred to as Vanilla FreeRTOS) is a compact and efficient real-time operating system supported on many single-core MCUs and SoCs. However, to support numerous dual-core ESP targets, such as ESP32, ESP32-S3, and ESP32-P4, ESP-IDF provides an implementation of FreeRTOS with dual-core symmetric multiprocessing (SMP) capabilities (hereinafter referred to as ESP-IDF FreeRTOS).
ESP-IDF FreeRTOS is based on Vanilla FreeRTOS v10.4.3 but contains significant modifications to both API and kernel behavior in order to support dual-core SMP. This document describes the API and behavioral differences between Vanilla FreeRTOS and ESP-IDF FreeRTOS.
