Allow the stats formatting functions to be built in without stdio.h being included inside tasks.c.
Kernel port code:
- Slight change to the Cortex-A GIC-less port to move all non portable code to the application level.
SAMA5D4 demo project:
- Update the Atmel provided library to V1.1.
- Create a DDR build configuration.
- Ensure interrupts are all edge sensitive.
- Update the regtest code to use all 32 flop registers.
+ Change how queues are allocated and deleted so only one pvPortMalloc() or vPortFree() is required in place of the previous 2.
+ Where the TCB is allocated in relation to the stack is now dependent on the stack growth direction. The stack will not grow into the TCB.
+ Introduce the configAPPLICATION_ALLOCATED_HEAP constant to allow the application to provide the array used by heap_4.c as its heap. This allows the application writer to use qualifiers on the array to, for example, force the memory into faster RAM.
Demo application:
+ Add demo for SAMA5D4 using IAR.
+ Introduce xSemaphoreGenericGiveFromISR() as an optimisation when giving semaphores and mutexes from an interrupt.
Demo applications:
+ Update IntSemTest.c to provide more code coverage in xSemaphoreGenericGiveFromISR().
+ Ensure the MMU is turned on in the RZ IAR demo. It was already on in the RZ ARM demo.
- Re-introduce the ability to give a mutex from an ISR.
Common demo code:
- Add additional tests into the GenQTest files for priority inheritance and using a mutex from an ISR.
Add additional asserts to the Keil CM3 and CM4F ports (other CM3/4 ports already updated).
Add the additional yield necessitated by the mutex held count to the case when configUSE_QUEUE_SETS is 0.
Helper updates to allow a count of the number of mutexes held to be added.
Updates to the CCS Cortex-R4 implementation necessitated by a change in compiler semantics.
Update PIC32MX and MZ ports to assert if a non ISR safe function is called from an ISR.
Fix issue in and simplify the xTaskRemoveFromUnorderedEventList() function. The function is new to the V8 release candidates so does not effect official released code.
Replace LDMFD with POP instructions in IAR and RVDS Cortex-A9 ports.
Replace branch to address with indirect branch and exchange to address in register in the IAR and RVDS Cortex-A9 ports.
Change INCLUDE_xTimerPendFunctionCallFromISR to INCLUDE_xTimerPendFunctionCall
Update event group trace macros to match the new trace recorder code.
Ensure parameter name consistency by renaming any occurrences of xBlockTime and xBlockTimeTicks to xTicksToWait.
Continue work on GCC/RL78 port - still a work in progress.
Adjust how the critical section was used in xQueueAddToSet.
Remove obsolete extern declaration of vTaskSwitchContext() from the MPX430X IAR portmacro.h (other older portmacro.h header files contain the same declaration).
When a task is unblocked the need for a context switch is only signalled if the unblocked task has a priority higher than the currently running task, instead of higher than or equal to the priority of the currently running task.
Replace #define types with typedefs.
Rename all typedefs to have a _t extension.
Add #defines to automatically convert old FreeRTOS specific types to their new names (with the _t).
Introduce xPortRunning variable into Win32 simulator port layer.
Add port optimised task selection macro for the GCC Win32 port layer (the MSVC version has had one for a while).
Ensure the event list item value does not get modified by code in tasks.c (priority inheritance, or priority change) when it is in use by the event group implementation.
Reset the expected block time variable when a task is suspended or deleted in case the value held in the variables was associated with the task just suspended or deleted.
Add a task pre-delete hook to allow the insertion of any port specific clean up when a task is deleted.
Increase use of 'const' qualifiers.
Add vPortCloseRunningThread() into the Win32 port layer to attempt to allow Windows threads to be closed more gracefully when a task deletes itself.
