@ -2,28 +2,106 @@ Changes between FreeRTOS V10.4.6 and TBD
|

|
||||
Documentation and download available at https://www.FreeRTOS.org/
|
||||
|
||||
+ Changed uxAutoReload parameter in timer functions to xAutoReload. The
|
||||
type is now BaseType_t. This matches the type of pdTRUE and pdFALSE.
|
||||
The new function xTimerGetAutoReload() provides the auto-reload state as
|
||||
a BaseType_t. The legacy function uxTimerGetAutoReload is retained with the
|
||||
original UBaseType_t return value.
|
||||
+ Add support for ARM Cortex-M55.
|
||||
+ Add vectored mode interrupt support to the RISC-V port.
|
||||
+ Heap improvements:
|
||||
- Add a check to heap_2 to track if a memory block is allocated to
|
||||
the application or not. The MSB of the size field is used for this
|
||||
purpose. The same check already exists in heap_4 and heap_5. This
|
||||
check prevents double free errors.
|
||||
- Add a new flag configHEAP_CLEAR_MEMORY_ON_FREE to heap_2, heap_4
|
||||
and heap_5. If the flag is set in FreeRTOSConfig.h then memory freed using
|
||||
vPortFree() is automatically cleared to zero.
|
||||
- Add a new API pvPortCalloc to heap_2, heap_4 and heap_5 which has the same
|
||||
signature as the standard library calloc function.
|
||||
+ Add the ability to override send and receive completed callbacks for each
|
||||
instance of a stream buffer or message buffer. Earlier there could be
|
||||
one send and one receive callback for all instances of stream and message
|
||||
buffers. Having separate callbacks per instance allows different message
|
||||
and stream buffers to be used differently - for example, some for inter core
|
||||
communication and others for same core communication.
|
||||
The feature can be controlled by setting the configuration option
|
||||
configUSE_SB_COMPLETED_CALLBACK in FreeRTOSConfig.h. When the option is set to 1,
|
||||
APIs xStreamBufferCreateWithCallback() or xStreamBufferCreateStaticWithCallback()
|
||||
(and likewise APIs for message buffer) can be used to create a stream buffer
|
||||
or message buffer instance with application provided callback overrides. When
|
||||
the option is set to 0, then the default callbacks as defined by
|
||||
sbSEND_COMPLETED() and sbRECEIVE_COMPLETED() macros are invoked. To maintain
|
||||
backwards compatibility, configUSE_SB_COMPLETED_CALLBACK defaults to 0. The
|
||||
functionality is currently not supported for MPU enabled ports.
|
||||
+ Add support to build and link FreeRTOS using CMake build system. Contributed
|
||||
by @yhsb2k.
|
||||
+ Add support to generate Software Bill of Materials (SBOM) for every release.
|
||||
+ Add support for 16 MPU regions to the GCC Cortex-M33 ports.
|
||||
+ Add ARM Cortex-M7 r0p0/r0p1 Errata 837070 workaround to ARM CM4 MPU ports.
|
||||
The application writer needs to define configENABLE_ERRATA_837070_WORKAROUND
|
||||
when using CM4 MPU ports on a Cortex-M7 r0p0/r0p1 core.
|
||||
+ Add configSYSTICK_CLOCK_HZ to Cortex-M0 ports. This is needed to support
|
||||
the case when the SysTick timer is not clocked from the same source as the CPU.
|
||||
+ Add hardware stack protection support to MicroBlazeV9 port. This ensures that
|
||||
the CPU immediately raises Stack Protection Violation exception as soon as any
|
||||
task violates its stack limits. Contributed by @uecasm.
|
||||
+ Introduce the configUSE_MINI_LIST_ITEM configuration option. When this
|
||||
option is set to 1, ListItem_t and MiniLitItem_t remain separate types.
|
||||
However, when configUSE_MINI_LIST_ITEM == 0, MiniLitItem_t and ListItem_t
|
||||
are both typedefs of the same struct xLIST_ITEM. This addresses some issues
|
||||
observed when strict-aliasing and link time optimization are enabled.
|
||||
To maintain backwards compatibility, configUSE_MINI_LIST_ITEM defaults to 1.
|
||||
+ Add the ability to override send and receive completed callbacks for each
|
||||
instance of a stream buffer or message buffer. The feature can be controlled
|
||||
by setting the configuration option configUSE_SB_COMPLETED_CALLBACK in
|
||||
FreeRTOSConfig.h. When the option is set to 1, APIs
|
||||
xStreamBufferCreateWithCallback() or xStreamBufferCreateStaticWithCallback()
|
||||
(and likewise APIs from message buffer) can be used to create a stream buffer
|
||||
or message buffer instance with application provided callback overrides. When
|
||||
the option is set to 0, then the default callbacks as defined by
|
||||
sbSEND_COMPLETED() and sbRECEIVE_COMPLETED() macros are invoked. To maintain
|
||||
backwards compatibility, configUSE_SB_COMPLETED_CALLBACK defaults to 0. The
|
||||
functionaility is currently not supported for MPU enabled ports.
|
||||
+ Simplify prvInitialiseNewTask to memset newly allocated TCB structures
|
||||
to zero, and remove code that set individual structure members to zero.
|
||||
+ Add prototype for prvPortYieldFromISR to the POSIX port so that it builds
|
||||
without any warning with -Wmissing-prototypes compiler option.
|
||||
+ Add top of stack and end of stack to the task info report obtained using
|
||||
vTaskGetInfo(). Contributed by @shreyasbharath.
|
||||
+ Add a cap to the cRxLock and cTxLock members of the queue data structure.
|
||||
These locks count the number items received and sent to the queue while
|
||||
the queue was locked. These are later used to unblock tasks waiting on
|
||||
the queue when the queue is unlocked. This PR caps the values of the
|
||||
cRxLock and cTxLock to the number of tasks in the system because we cannot
|
||||
unblock more tasks than there are in the system. Note that the same assert
|
||||
could still be triggered is the application creates more than 127 tasks.
|
||||
+ Changed uxAutoReload parameter in timer functions to xAutoReload. The
|
||||
type is now BaseType_t. This matches the type of pdTRUE and pdFALSE.
|
||||
The new function xTimerGetAutoReload() provides the auto-reload state as
|
||||
a BaseType_t. The legacy function uxTimerGetAutoReload is retained with the
|
||||
original UBaseType_t return value.
|
||||
+ Fix support for user implementations of tickless idle that call
|
||||
vTaskStepTick() with xExpectedIdleTime ticks to step. The new code
|
||||
ensures xTickCount reaches xNextTaskUnblockTime inside xTaskIncrementTick()
|
||||
instead of inside vTaskStepTick(). This fixes the typical case where a task
|
||||
wakes up one tick late and a rare case assertion failure when xTickCount\
|
||||
rolls over. Contributed by @jefftenney.
|
||||
+ Fix deadlock in event groups when pvPortMalloc and vPortFree functions
|
||||
are protected with a mutex. Contributed by @clemenskresser.
|
||||
+ Fix a warning in tasks.c when compiled with -Wduplicated-branches
|
||||
GCC option. Contributed by @pierrenoel-bouteville-act.
|
||||
+ Fix compilation error in tasks.c when configSUPPORT_DYNAMIC_ALLOCATION
|
||||
is set to zero. Contributed by @rdpoor.
|
||||
+ Fix prvWriteMessageToBuffer() function in stream_buffer.c so that it correctly
|
||||
copies length on big endian platforms too.
|
||||
+ Remove the need for INCLUDE_vTaskSuspend to be set to 1
|
||||
when configUSE_TICKLESS_IDLE is enabled. Contributed by @pramithkv.
|
||||
+ Update the RL78 IAR port to the latest version of IAR which uses the
|
||||
industry standard ELF format as opposed to earlier UBROF object format.
|
||||
Contributed by @felipe-iar.
|
||||
+ Add tick type is atomic flag when tick count is 16-bit to PIC24 port. This
|
||||
allows the PIC24 family of 16 bit processors to read the tick count without
|
||||
a critical section when the tick count is also 16 bits.
|
||||
+ Fix offset-out-of-range errors for GCC CM3/CM4 mpu ports when
|
||||
Link Time Optimization is enabled. Contributed by @niniemann.
|
||||
+ Remove #error when RISC-V port is compiled on a 64-bit RISC-V platform.
|
||||
Contributed by @cmdrf.
|
||||
+ Fix ullPortInterruptNesting alignment in Cortex-A53 port so that it is
|
||||
8-byte aligned. This fixes the unaligned access exception. Contributed
|
||||
by @Atomar25.
|
||||
+ Fix Interrupt Handler Register Function and Exception Process in NiosII
|
||||
Port. Contributed by @ghost.
|
||||
+ Change FreeRTOS IRQ Handler for Cortex-A53 SRE port to store and restore
|
||||
interrupt acknowledge register. This ensures that the SRE port behavior
|
||||
matches the Memory Mapped IO port. Contributed by @sviaunxp.
|
||||
+ Update the uncrustify config file to match the version of the uncrustify
|
||||
used in the CI Action. Also, pin the version of uncrustify in CI. Contributed
|
||||
by @swaldhoer.
