- 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.
- 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.
+ Support tickless idle when configUSE_PREEMPTION is 0 (previously tickless idle was only supported when the pre-emptive scheduler was being used).
+ If a stack was statically allocated, then don't try freeing it if the TCB cannot be allocated.
+ Remove use of INCLUDE_xEventGroupsSetBitsFromISR() pre-processor macro, as it was not tested anyway.
Demo app changes:
+ Updated SAM4L Atmel Studio project to use Atmel Studio 7.
FreeRTOS+Trace:
- Add trace macros for task notifications.
- Update to the latest trace recorder library.
Demo projects:
- Only include the CLI command to show run time states if configGENERATE_RUN_TIME_STATS is set to 1.
Update WinPCap NetworkInterface.c for FreeRTOS+UDP to correctly store a pointer to the network buffer structure at the beginning of the network buffer.
Remove redundant global definition vPortInstallFreeRTOSVectorTable from the GCC ARM_CA9 portASM.S file.
Ensure correct sequence of start up sequence when the Windows port is used on multi-core Windows machines by starting one thread in the suspended state.
Move initialisation of xNextTaskUnblockTime to the function that starts the scheduler, rather than from where the variable is declared - this fixes a compiler warning in newer IAR compilers.
Fix "elif (SELECTED_PORT == PORT_MICROCHIP_PIC32MX || PORT_MICROCHIP_PIC32MZ)" in the FreeRTOS+Trace trcHardwarePort.h header file.
Add a "query heap" command to the standard sample CLI commands.
Remove casting from configMAX_PRIORITIES setting in Win32 simulator demos as it was preventing a clean build.
Source code changes.
General tidy up and addition of assert points.
+ Made xTaskNotifyGiveFromISR() its own function, rather than a macro that calls xTaskNotifyFromISR() (minor performance improvement).
+ GCC and Keil Cortex-M4F ports now use vPortRaiseBASEPRI() in place of ulPortRaiseBASEPRI() where the return value is not required (minor performance improvement).
Demo changes:
Change the [very basic] FreeRTOS+UDP SAM4E driver to use task notifications rather than a semaphore (execution time now 55% what it was in FreeRTOS V8.1.2!).
Robustness improvements to IntQueue.c standard demo task.h.
Added the latest standard demo tasks, reg test tasks and int q tasks to the SAM4E demo.
+ Optimise Cortex-M4F ports by inlining some critical section macros.
+ Original ports used a #define to set the path to portmacro.h - that method has been obsolete for years and now all the old definitions have been moved into a separate header files called deprecated_definitions.h.
+ Cortex-M port now check the active vector bits against 0xff when determining if a function is called from an interrupt - previously only a subset of the bits (0x1f) were checked.
+ Add in new standard demo/test files TaskNotify.c/h and include the files in the simulator demos.
+ Update trace recorder code, and some demos to use the new version (more to do).
+ Introduce uxTaskPriorityGetFromISR().
+ Minor typo corrections.
+ Update MingW simulator demo to match the MSVC simulator demo.
Correct the check to ensure the application network event hook is not called when the first network down event is sent.
Add in defaults for the Nabto task stack and priority.
