+ SMP merged into the mainline: While FreeRTOS introduced Asymmetric Multiprocessing (AMP) support in 2017, FreeRTOS Version 11.0.0 is the first to merge Symmetric Multiprocessing (SMP) support into the mainline release. SMP enables one instance of the FreeRTOS Kernel to schedule tasks across multiple identical processor cores. We thank Mike Bruno and Jerry McCarthy of XMOS and, Darian Liang, Sudeep Mohanty and Zim Kalinowski of Espressif Systems for their contributions. + Switch MISRA compliance checking from PC Lint to Coverity, and update from MISRA C:2004 to MISRA C:2012. + Add a template FreeRTOSConfig.h, inclusive of an abbreviated explanation of each configuration item. Application writers can use this template as a starting point to create the FreeRTOSConfig.h file for their application. + Add a template FreeRTOS port which can be used as a starting point for developing a new FreeRTOS port. + Add bounds checking and obfuscation to internal heap block pointers in heap_4.c and heap_5.c to help catch pointer corruptions. The application can enable these checks by setting configENABLE_HEAP_PROTECTOR to 1 in their FreeRTOSConfig.h. We thank @oliverlavery for their contribution. + Update vTaskList and vTaskGetRunTimeStats APIs to replace the use of sprintf with snprintf. + Add trace macros to ports that enable tracing the interaction of ISRs with scheduler events. We thank @conara for their contribution. + Add trace macros that enable tracing of entering and exiting all APIs. We thank @Techcore123 for their contribution. + Add uxTaskBasePriorityGet and uxTaskBasePriorityGetFromISR APIs to get the base priority of a task. The base priority of a task is the priority that was last assigned to the task - which due to priority inheritance, may not be the current priority of the task. + Add pdTICKS_TO_MS macro to convert time in FreeRTOS ticks to time in milliseconds. We thank @Dazza0 for their contribution. + Add default implementations of vApplicationGetIdleTaskMemory and vApplicationGetTimerTaskMemory. The application can enable these default implementations by setting configKERNEL_PROVIDED_STATIC_MEMORY to 1 in their FreeRTOSConfig.h. We thank @mdnr-g for their contribution. + Update vTaskGetInfo to include start and end of the stack whenever both values are available. We thank @vinceburns for their contribution. + Prevent tasks waiting for a notification from being resumed by calls to vTaskResume or vTaskResumeFromISR.

We thank @jefftenney for their contribution. + Rename ARM_CA53_64_BIT and ARM_CA53_64_BIT_SRE ports to Arm_AARCH64 and Arm_AARCH64_SRE respectively as these ports are applicable to all AArch64 architecture.

We thank @JoeBenczarski for their contribution. + Add CMake support to allow the application writer to build an application with static allocation only. We thank @conara for their contribution. + Make taskYIELD available to unprivileged tasks for ARMv8-M ports. + Update Cortex-M23 ports to not use PSPLIM_NS. We thank @urutva for their contribution. + Update the SysTick setup code for ARMv8-M ports to first configure the clock source and then enable SysTick. This is needed to address a bug in QEMU versions older than 7.0.0, which causes an emulation error if SysTick is enabled without first selecting a valid clock source. We thank @jefftenney for their contribution. + Add the port-optimized task selection algorithm optionally available for ARMv7-M ports to the ARMv8-M ports. We thank @jefftenney for their contribution. + Improve the speed of pvPortMalloc in heap_4.c and heap_5.c by removing unnecessary steps while splitting a large memory block into two. We thank @Moral-Hao for their contribution. + Shorten the critical section in pvPortMalloc in heap_2.c, heap_4.c and heap_5.c by moving the size calculation out of the critical section. We thank @Moral-Hao for their contribution. + Update xTaskNotifyWait and ulTaskNotifyTake to remove the non-deterministic operation of traversing a linked link from a critical section.

We thank @Moral-Hao for their contribution. + Add stack alignment adjustment if stack grows upwards. We thank @ivq for their contribution. + Fix pxTopOfStack calculation in configINIT_TLS_BLOCK when picolib C is selected as the C library implementation to ensure that pxPortInitialiseStack does not overwrite the data in the TLS block portion of the stack. We thank @bebebib-rs for their contribution. + Fix vPortEndScheduler() for the MSVC port so that the function prvProcessSimulatedInterrupts is not stuck in an infinite loop when the scheduler is stopped. We thank @Ju1He1 for their contribution. + Add the Pull Request (PR) Process explaining the stages a PR goes through. 

+ Add the following improvements to the new MPU wrapper (mpu_wrappers_v2.c) introduced in version 10.6.0: - Introduce Access Control List (ACL) feature to allow the application writer to control an unprivileged task’s access to kernel objects. - Update the system call entry mechanism to only require one Supervisor Call (SVC) instruction. - Wrap parameters for system calls with more than four parameters in a struct to avoid special handling during system call entry. - Fix 2 possible integer overflows. - Convert some asserts to run time parameter checks. 

+ Add runtime parameter checks to functions in mpu_wrappers_v2.c file. The same checks are already performed in API implementations using asserts. We thank the following people for their inputs in these changes: - Lan Luo, Zixia Liu of School of Computer Science and Technology, Anhui University of Technology, China. - Xinwen Fu of Department of Computer Science, University of Massachusetts Lowell, USA. - Xinhui Shao, Yumeng Wei, Huaiyu Yan, Zhen Ling of School of Computer Science and Engineering, Southeast University, China. 

+ Add a new MPU wrapper that places additional restrictions on unprivileged tasks. The following is the list of changes introduced with the new MPU wrapper: 1. Opaque and indirectly verifiable integers for kernel object handles: All the kernel object handles (for example, queue handles) are now opaque integers. Previously object handles were raw pointers. 2. Save the task context in Task Control Block (TCB): When a task is swapped out by the scheduler, the task's context is now saved in its TCB. Previously the task's context was saved on its stack. 3. Execute system calls on a separate privileged only stack: FreeRTOS system calls, which execute with elevated privilege, now use a separate privileged only stack. Previously system calls used the calling task's stack. The application writer can control the size of the system call stack using new configSYSTEM_CALL_STACK_SIZE config macro. 4. Memory bounds checks: FreeRTOS system calls which accept a pointer and de-reference it, now verify that the calling task has required permissions to access the memory location referenced by the pointer. 5. System calls restrictions: The following system calls are no longer available to unprivileged tasks: - vQueueDelete - xQueueCreateMutex - xQueueCreateMutexStatic - xQueueCreateCountingSemaphore - xQueueCreateCountingSemaphoreStatic - xQueueGenericCreate - xQueueGenericCreateStatic - xQueueCreateSet - xQueueRemoveFromSet - xQueueGenericReset - xTaskCreate - xTaskCreateStatic - vTaskDelete - vTaskPrioritySet - vTaskSuspendAll - xTaskResumeAll - xTaskGetHandle - xTaskCallApplicationTaskHook - vTaskList - vTaskGetRunTimeStats - xTaskCatchUpTicks - xEventGroupCreate - xEventGroupCreateStatic - vEventGroupDelete - xStreamBufferGenericCreate - xStreamBufferGenericCreateStatic - vStreamBufferDelete - xStreamBufferReset Also,...
