+
+## Announcement:
+
+FreeRTOS SMP feature has been merged into [FreeRTOS-Kernel](https://github.com/FreeRTOS/FreeRTOS-Kernel/commit/ae3a498e435cecdb25b889f2740ea99027dd0cb1) main branch. We recommend you to use the [FreeRTOS-Kernel](https://github.com/FreeRTOS/FreeRTOS-Kernel/commit/ae3a498e435cecdb25b889f2740ea99027dd0cb1) main branch to develop FreeRTOS SMP applications.
+
+The contents of this branch will remain available for certain period but we will no longer provide updates or accept new contributions and pull requests.
+
+Have more questions? Post them in the [FreeRTOS forum](https://forums.freertos.org/).
+
+
+## Migrate port from SMP branch to FreeRTOS v11
+
+The following changes should be applied to migrate a port from this branch to FreeRTOS v11:
+
+* Call `xTaskIncrementTick` in critical section in port
+
+RP2040 example:
+```c
+void xPortSysTickHandler( void )
+{
+    portBASE_TYPE xPreviousMask;
+
+    /* xTaskIncrementTick now must be called in critical section. */
+    xPreviousMask = taskENTER_CRITICAL_FROM_ISR();
+    {
+        /* Increment the RTOS tick. */
+        if( xTaskIncrementTick() != pdFALSE )
+        {
+            /* Pend a context switch. */
+            portNVIC_INT_CTRL_REG = portNVIC_PENDSVSET_BIT;
+        }
+    }
+    taskEXIT_CRITICAL_FROM_ISR( xPreviousMask );
+}
+```
+
+* Rename `configNUM_CORES` to `configNUMBER_OF_CORES`
+
+* Define `portSET/CLEAR_INTERRUPT_MASK` in port
+
+* Define `portENTER/EXIT_CRITICAL_FROM_ISR` for SMP in port
+    * These macros should be implemented with `vTaskEnterCriticalFromISR`/`xTaskExitCriticalFromISR`
+ 
+* Update `portSET/CLEAR_INTERRUPT_MASK_FROM_ISR` implementation in port
+    * SMP-dev doesn<73>t use these macros to enter/exit critical section from ISR. Instead,
+ `portENTER/EXIT_CRITICAL_FROM_ISR` are used. These functions should be implemented as
+ the macro name suggested, set or clear interrupt mask from ISR if nested interrupt are supported.
+
+

 ## Getting started
 This repository contains FreeRTOS kernel source/header files and kernel ports only. This repository is referenced as a submodule in [FreeRTOS/FreeRTOS](https://github.com/FreeRTOS/FreeRTOS) repository, which contains pre-configured demo application projects under ```FreeRTOS/Demo``` directory.

chinglee-iot	0f9e6e5b52	Remove prvSelectHighestPriorityTask call in vTaskSuspend (#610 ) * Remove prvSelectHighestPriorityTask call in vTaskSuspend * Every core starts with an idle task in SMP implementation and taskTASK_IS_RUNNING only return ture when the task is idle task before scheduler started. So prvSelectHighestPriorityTask won't be called in vTaskSuspend before scheduler started. * Update prvSelectHighestPriorityTask to ensure that this function is called only when scheduler started. * Fix kernel checker error	2023-01-24 13:55:36 +05:30

Sudeep Mohanty	2eff037080	Update prvYieldCore() compile warning for single core targets (#505 ) When configNUM_CORES is 1, prvYieldCore() generates an array subscript outofbound error (-Warray-bounds) when compiled with GCC with space optimization enabled (-Os). This commit updates the code flow in prvYieldCore() to compile out the part where yield is needed on the other core which is unnecessary for single-core targets.	2022-06-22 10:03:44 +05:30

Darian	34b8e24d7c	Add support for newlib dynamic reentrancy (#496 ) Previously, newlib's _impure_ptr was updated on every context switch to point to the current task's _reent structure. However, this behavior is no longer valid on multi-core systems due to the fact that multiple cores can switch contexts at the same time, thus leading to the corruption of the _impure_ptr. However, Newlib can be compiled with __DYNAMIC_REENT__ enabled which will cause newlib functions to call __getreent() instead in order to obtain the required reent struct. This commit adds dynamic reentrancy support to FreeRTOS: - Added a configNEWLIB_REENTRANT_IS_DYNAMIC to enable dynamic reentrancy support - _impure_ptr is no longer updated with reentrancy is dynamic - Port must provide their own __getreent() that returns the current task's reent struct	2022-05-31 16:11:02 -07:00
Darian	a97741a08d	Add task creation with affinity functions (#470 ) This commit adds the functions listed below.

Timo Sandmann	4832377117	smp branch: bugfix for race condition on RP2040 (#431 ) * Bugfix for race condition on RP2040 in vPortEnableInterrupts() RP2040 SMP port: Since spin_unlock() re-enables interrupts, pxYieldSpinLock has to be updated first to avoid a possible race condition. * Bugfix for invalid sanity checks on RP2040 RP2040 SMP port: Testing pxYieldSpinLock for NULL does not work reliable in these places, because another/new lock might already be set when configASSERT() is executed.	2021-12-28 12:30:03 -08:00

Michael Bruno	a7092d400c	Fix XCore DP/CP register corruption bug (#352 ) The kernel code that runs within RTOS ISRs requires that DP and CP not be changed from their initial values. If a task changes them and is interrupted while they are changed, then they must be restored for the ISR. This commit implements this.
