Changes between FreeRTOS V11.0.1 and FreeRTOS V11.1.0 released April 22, 2024
+ Add ARMv7-R port with Memory Protection Unit (MPU) support.
+ Add Memory Protection Unit (MPU) support to the Cortex-M0 port.
+ Add stream batching buffer. A stream batching buffer differs from a stream
buffer when a task reads from a non-empty buffer:
- The task reading from a non-empty stream buffer returns immediately
regardless of the amount of data in the buffer.
- The task reading from a non-empty steam batching buffer blocks until the
amount of data in the buffer exceeds the trigger level or the block time
expires.
We thank @cperkulator for their contribution.
+ Add the ability to change task notification index for stream buffers. We
thank @glemco for their contribution.
+ Add xStreamBufferResetFromISR and xMessageBufferResetFromISR APIs to reset
stream buffer and message buffer from an Interrupt Service Routine (ISR).
We thank @HagaiMoshe for their contribution.
+ Update all the FreeRTOS APIs to use configSTACK_DEPTH_TYPE for stack type.
We thank @feilipu for their contribution.
+ Update vTaskEndScheduler to delete the timer and idle tasks,
once the scheduler is stopped.
+ Make xTaskGetCurrentTaskHandleForCore() available to the single core
scheduler. We thank @Dazza0 for their contribution.
+ Update uxTaskGetSystemState to not use the pxIndex member of the List_t
structure while iterating ready tasks list. The reason is that pxIndex
member must only used to select next ready task to run. We thank
@gemarcano for their inputs.
+ Add a config option to the FreeRTOS SMP Kernel to set the default core
affinity mask for tasks created without an affinity mask. We thank @go2sh
for their contribution.
+ Add configUSE_EVENT_GROUPS and configUSE_STREAM_BUFFERS configuration
constants to control the inclusion of event group and stream buffer
functionalities.
+ Code changes to comply with MISRA C 2012.
+ Add 64-bit support to the FreeRTOS Windows Simulator port. We thank @watsk
and @josesimoes for their contributions.
+ Add support for 64-bit Microblaze processor to the MicroblazeV9 port. We
thank @mubinsyed for their contribution.
+ Add support for MSP430 Embedded Application Binary Interface (EABI) to
the MSP430F449 port to make it work with both MSP430 GCC and MSPGCC
compilers. We thank @Forty-Bot for their contribution.
+ Update xPortIsAuthorizedToAccessBuffer() on FreeRTOS ports with MPU
support to grant an unprivileged task access to all the memory before the
scheduler is started.
+ Update the POSIX port to pass the FreeRTOS task name to pthread for
readable output in debuggers. We thank @Mixaill for their contribution.
+ Update the POSIX port to ignore the user specified stack memory and only
pass the stack size to the pthread API to avoid errors caused when stack size
is smaller than the minimum. We thank @cmorgnaBE for their
contribution.
+ Update the POSIX port to use a timer thread for tick interrupts instead of
POSIX timers to address issues with signal handling in non-FreeRTOS
pthreads. We thank @cmorgnaBE for their contribution.
+ Update ARM_TFM port to support TF-Mv2.0.0 release of trusted-firmware-m.
We thanks @urutva for their contribution.
+ Remove redundant constant pools in ARMv8 ports. We thank @urutva for their
contribution.
+ Add APIs to reset the internal state of kernel modules. These APIs are
primarily intended to be used in the testing frameworks that restart the
scheduler.
+ Use kernel provided implementations of vApplicationGetIdleTaskMemory() and
vApplicationGetTimerTaskMemory() in the RP2040 port. We thank @dpslwk for
their contribution.
+ Fix atomic enter/exit critical section macro definitions in atomic.h for
ports that support nested interrupts. We thank @sebunger for their
contribution.
+ Fix compiler warnings in the MSP430F449 port when compiled with the
MSP430 GCC compiler. We thank @Forty-Bot for their contribution.
+ Update the scheduler suspension usage in ulTaskGenericNotifyTake and
xTaskGenericNotifyWait() to enhance code readability. We thank @Dazza0 for
their contribution.
+ Add support for latest version of MPU wrappers( mpu_wrappers_v2) in CMake.
We thank @IsaacDynamo for their contribution.
+ Update CMake support to create only one static library containing both the
kernel common code and the kernel port code. We thank @barnatahmed for
their contribution.
