Updated pvContainer member of list items to List_t * rather than void * as they are always contained in a list if anywhere.
Made EventGroupHandle_t typesafe pointer to forward referenced struct rather than void pointer.
Made TaskHandle_t typesafe pointer to forward referenced struct, rather than a void pointer.
Correct definition of StaticTask_t in the case that portUSE_MPU_WRAPPERS is set to 1.
prvTaskCheckFreeStackSpace() now returns configSTACK_DEPTH_TYPE to allow return values greater than max uint16_t value if required.
xStreamBufferSend() and xStreamBufferReceive() no longer clear task notification bits - clearing was unnecessary as only the task notification state is used.
FreeRTOS+TCP: Improve print output when using WinPCap to assist in selecting the correct network interface.
FreeRTOS kernel: Fix extern "C" { in stream_buffer.h.
FreeRTOS kernel: Correct tskKERNEL_VERSION_NUMBER and tskKERNEL_VERSION_MAJOR constants for V10.
Ensure the currently executing task is printed correctly in vTaskList().
Added test code to GenQTest to test the new priority dis-inheritance functionality.
Allow the default names given to the Idle and Timer tasks to be overwridden by definitions in FreeRTOSConfig.h.
Introduce configSTACK_DEPTH_TYPE so the application writer change the type used to specify a stack size from uint16_t to whatever they like. Defaults to uint16_t if not defined.
Introduce configINITIAL_TICK_COUNT to allow users to start the tick count at something other than 0. Used for testing, but overflows can be better tested by setting configUSE_16_BIT_TICKS to 1.
Split xQueueGenericReceive() into xQueueReceive(), xQueuePeek() and xQueueSemaphoreTake() as the first step in refactoring xQueueGenericReceive().
Add Cortex-M3 port layer for Code Composer Studio - previously there was only a Cortex-M4F port.
Introduce configPRE_SUPPRESS_TICKS_AND_SLEEP_PROCESSING() to allow applications to prevent portSUPPRESS_TICKS_AND_SLEEP() being called. Previously the portPRE_SLEEP_PROCESSING() macro could only be used to abort entry into sleep time after clocks had been re-programmed for the distant wake time.
Introduce configINCLUDE_FREERTOS_TASK_C_ADDITIONS_H, which allows a user provided header file to be included at the bottom of the tasks.c source file, which can add user functions and access file scope data.
Replace global on/off switches used for lint errors with save/restore switches.
+ Add configASSERT() into ARM Cortex-M ports to check the number of priority
bit settings.
+ Clear the 'control' register before starting ARM Cortex-M4F ports in case
the FPU is used before the scheduler is started. This just saves a few
bytes on the main stack as it prevents space being left for a later save
of FPU registers.
+ Added xSemaphoreGetMutexHolderFromISR().
+ Corrected use of portNVIC_PENDSVSET to portNVIC_PENDSVSET_BIT in MPU ports.
- Clear the SysTick current value register before starting the SysTick (only required if something uses SysTick before starting the scheduler).
- Ensure atomic operations are thread safe by executing clrex in the context switch.
+ Set flash wait states on MSP432 demos.
+ Remove use of obsolete IO library in PIC32 demos.
+ Remove obsolete item left on stack of first task to run in the Cortex-M0 ports.
+ Correct IA32 GCC vPortExitCritical() implementation when configMAX_API_CALL_INTERRUPT_PRIORITY == portMAX_PRIORITY.
Tidy up CEC1302 demo.
Ensure bit 0 of the task address is clear when setting up stack of initial Cortex-M3/4/7 stacks (for strict compliance, although not practically necessary).
vTaskGetTaskInfo() changed to vTaskGetInfo() - with a macro added for backward compatibility.
Reduce the number of xTaskCreateStatic() parameters by having the function return the task handle, rather than pass the task handle out using a parameter. This is also consistent with other objectCreate() functions.
+ The MPU port is not supported in this revision number.
+ The documentation for the static allocation functions in the header files has not yet been updated for this revision.
Kernel updates:
+ Simplify the static allocation of objects implementation.
+ Introduce configSUPPORT_DYNAMIC_ALLOCATION in addition to the existing configSUPPORT_STATIC_ALLOCATION so FreeRTOS can be built without providing a heap at all.
Demo application updates:
+ Update the demos to take into account the new configSUPPORT_DYNAMIC_ALLOCATION constant.
+ Add an MSVC demo that only uses static allocation, and does not include a FreeRTOS heap.
+ Update the MSVC project to use both configSUPPORT_STATIC_ALLOCATION and configSUPPORT_DYNAMIC_ALLOCATION.
+ Update the MingW project to use only configSUPPORT_DYNAMIC_ALLOCATION.
Fix build error when configSUPPORT_STATIC_ALLOCATION and configNUM_THREAD_LOCAL_STORAGE_POINTERS were greater than zero at the same time.
Allow the pdMS_TO_TICKS macro to be overridden by a definition in FreeRTOSConfig.h.
- Remove the standard demo files that used the [long since deprecated] alternative API.
- Add standard demo task that tests the new xTaskAbortDelay() function.
- Update the Win32 Visual Studio project to use Visual Studio 2015 Community Edition.
- Rename the xGenericListItem TCB member to xStateListItem as it better describes the member's purpose.
+ Added xTaskAbortDelay() function, which causes a task to exit the Blocked state even before the timeout has expired or the event the task is waiting for has occurred.
+ For efficiency and code size reasons on some architectures, replace many instances of "== pdTRUE" with "!= pdFALSE".
- Major refactor to consolidate the multiple places where a task is removed from a ready list and placed in a delay list into a single function, reducing code size, and enabling the easy addition of up-coming functionality.
- Replace the enum used for task notification states with a uint8_t to reduce the TCB struct size with some compilers, and allow additional members to be added without increasing its size.
- Rearrange FreeRTOS.h so all INCLUDE_ defaults are grouped together.
Add a member to the TaskStatus_t structure that is used to return the base address of the stack used by the task being queried.
Add xTaskGetTaskHandle() that allows the handle of a task to be looked up from the task's text name.
Continue to document the macros that allow RTOS objects to be created using statically allocated memory.
Introduced vApplicationDaemonTaskStartupHook(), which allows initialisation that that needs to be executed after the scheduler has been started to be executed from the RTOS daemon task.
Call prvResetNextTaskUnblockTime() in xTaskResumeAll() if a task is moved from the pending ready list - this can prevent an unnecessary wake from sleep mode if a task is unblocked by an interrupt while in a low power tickless state.
