Changes between FreeRTOS V11.0.0 and FreeRTOS V11.0.1 released December 21, 2023
+ Updated the SBOM file.
Changes between FreeRTOS V10.6.2 and FreeRTOS V11.0.0 released December 18, 2023
+ 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 @Moral-Hao for their
contribution.
+ Add asserts to validate that the application has correctly installed
FreeRTOS handlers for PendSV and SVCall interrupts on Cortex-M devices.
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 @urutva for their contribution.
+ Add CMake support to allow the application writer to select the RISC-V
chip extension. 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
@karver8 for their contribution.
+ Fix stack end and stack size computation in POSIX port to meet the stack
alignment requirements on MacOS. We thank @tegimeki for their contribution.
+ Update the vTaskPrioritySet implementation to use the new priority when the
task has inherited priority from a mutex it is holding, and the new priority
is bigger than the inherited priority. 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.
Changes between FreeRTOS V10.6.1 and FreeRTOS V10.6.2 released November 29, 2023
+ 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.
Changes between FreeRTOS V10.6.0 and FreeRTOS V10.6.1 released August 17, 2023
+ 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.
Changes between FreeRTOS V10.5.1 and FreeRTOS 10.6.0 released July 13, 2023

from the assembly code in the port files. Therefore, adding a declaration in
header file is not useful as the assembly code will still need to declare it
separately.
- MISRA C:2012 Rule 8.4: A compatible declaration shall be visible when an

pxCurrentTCB(s) is defined with external linkage but it is only
referenced from the assembly code in the port files. Therefore, adding
a declaration in header file is not useful as the assembly code will

_Ref 8.4.2_
- xQueueRegistry is defined with external linkage because it is accessed by the

#### Rule 8.6
MISRA C:2012 Rule 8.6: An identifier with external linkage shall have exactly
one external definition.
_Ref 8.6.1_
- This rule prohibits an identifier with external linkage to have multiple
definitions or no definition. FreeRTOS hook functions are implemented in
the application and therefore, have no definition in the Kernel code.
#### Rule 11.1
MISRA C:2012 Rule 11.1: Conversions shall not be performed between a pointer to

```
_Ref 11.5.1_
- The memory blocks returned by pvPortMalloc() are guaranteed to meet the
architecture alignment requirements specified by portBYTE_ALIGNMENT.
The casting of the pointer to void returned by pvPortMalloc() is,
therefore, safe because it is guaranteed to be aligned.
_Ref 11.5.2_
- The conversion from a pointer to void into a pointer to EventGroup_t is
safe because it is a pointer to EventGroup_t, which is returned to the
application at the time of event group creation for data hiding
purposes.
_Ref 11.5.3_
- The conversion from a pointer to void in list macros for list item owner
is safe because the type of the pointer stored and retrieved is the
same.
_Ref 11.5.4_
- The conversion from a pointer to void into a pointer to EventGroup_t is
safe because it is a pointer to EventGroup_t, which is passed as a
parameter to the xTimerPendFunctionCallFromISR API when the callback is
pended.
_Ref 11.5.5_
- The conversion from a pointer to void into a pointer to uint8_t is safe
because data storage buffers are implemented as uint8_t arrays for the
ease of sizing, alignment and access.
#### Rule 21.6
MISRA C-2012 Rule 21.6: The Standard Library input/output functions shall not
be used.
_Ref 21.6.1_
- The Standard Library function snprintf is used in vTaskListTasks and
vTaskGetRunTimeStatistics APIs, both of which are utility functions only and
are not considered part of core kernel implementation.

# MISRA Compliance for FreeRTOS-Kernel
FreeRTOS-Kernel is MISRA C:2012 compliant. This directory contains a project to
run [Synopsys Coverity](https://www.synopsys.com/software-integrity/security-testing/static-analysis-sast.html)
for checking MISRA compliance.
> **Note**
Coverity version 2022.6.1 incorrectly infers the type of `pdTRUE` and `pdFALSE`
as boolean because of their names, resulting in multiple false positive warnings
about type mismatch. We replace `pdTRUE` with `pdPASS` and `pdFALSE` with
`pdFAIL` to avoid these false positive warnings. This workaround will not be
needed after Coverity fixes the issue of incorrectly inferring the type of
`pdTRUE` and `pdFALSE` as boolean.
Deviations from the MISRA C:2012 guidelines are documented in
[MISRA.md](../../MISRA.md) and [coverity_misra.config](coverity_misra.config)
files.
## Getting Started
### Prerequisites
Coverity can be run on any platform mentioned [here](https://sig-docs.synopsys.com/polaris/topics/c_coverity-compatible-platforms.html).
The following are the prerequisites to generate coverity report:
1. CMake version > 3.13.0 (You can check whether you have this by typing `cmake --version`).
2. GCC compiler.
- See download and installation instructions [here](https://gcc.gnu.org/install/).
3. Clone the repo using the following command:
- `git clone https://github.com/FreeRTOS/FreeRTOS-Kernel.git ./FreeRTOS-Kernel`
### Generating Report
Go to the root directory of the FreeRTOS-Kernel repo and run the following
commands in a terminal:
1. Update the compiler configuration in Coverity:
~~~
cov-configure --force --compiler cc --comptype gcc
~~~
2. Create the build files using CMake in a `build` directory:
~~~
cmake -B build -S examples/coverity
~~~
3. Build the (pseudo) application:
~~~
cd build/
cov-build --emit-complementary-info --dir cov-out make
~~~
4. Go to the Coverity output directory (`cov-out`) and begin Coverity static
analysis:
~~~
cd cov-out/
cov-analyze --dir ./cov-out \
--coding-standard-config ../examples/coverity/coverity_misra.config \
--tu-pattern "file('.*/FreeRTOS/Source/[A-Za-z_]*\.c')
~~~
5. Generate the HTML report:
~~~
cov-format-errors --dir ./cov-out --html-output html-output
~~~
HTML report should now be generated in a directory named `html-output`.
