* Removing FreeRTOS/Source in readiness for submoduling.
* Submoduling kernel.
* README.md update due to submoduling.
When releasing, please follow these steps:
1. in local directory, clean directory and check "git status" shows "nothing to commit, working tree clean" for ALL subdirectories.
2. copy source code and instructions only to an empty folder. Git related should not be in this folder -- this covers .git, .gitignore, .github, .gitmodules, gitmessages, ......
3. zip the folder from step 2. (create both .zip and .7z)
4. attach .zip and .7z to the release. (e.g. attach these two in new release -- https://github.com/FreeRTOS/FreeRTOS/releases/new)
5. PLEASE download both, unzip, diff with your local git repo. (should not see any difference other than git related.) And, sanity check a couple of projects.
Make clock setup functions weak symbols in ARMv8-M ports.
Update Cortex-M33 ports to use an interrupt mask in place of globally disabling interrupts, as per the other Cortex-M ports.
For projects depending on either of these two ports, please update your projects according to below:
Wiced_CY -- Use GCC/ARM_CRx_No_GIC instead.
nrf52840-dk -- Use GCC/ARM_CM7/r0p1 instead. Please note that, kernel port shall only take dependency on MCU core, not MCU peripherals. (Please take out RTC related from kernel port.) For low power feature (tickless) in FreeRTOS, please follow this page https://www.freertos.org/low-power-ARM-cortex-rtos.html. In case ARM_CM7/rop1 is missing any feature, reach out to us.
- System calls are now only allowed from kernel code. This change can be turned on
or off using configENFORCE_SYSTEM_CALLS_FROM_KERNEL_ONLY.
- MPU is disabled before reprogramming it and enabled afterwards to be compliant
with ARM recommendations.
Added tests for xTaskAbortDelayFromISR() into Demo/Common/Minimal/AbortDelay.c.
Added tests for ulTaskNotifyValueClear() into Demo/Common/Minimal/TaskNotify.c.
- Added back power static library for GCC and IAR. (Power management related interface definitions are in drivers/fsl_power.h. power.c is empty due to "implementation is in header file and power library")
- Note for GCC link: the command used for linking is `arm-none-eabi-gcc -nostdlib -L<additional lib search path> -Xlinker ... -o "CORTEX_M0+_LPC51U68_LPCXpresso.axf" <all *.o> -lpower`. Per GCC doc, static library name in file system is libpower.a.

Earlier we were using hard-coded addresses for MPU setup which
were ensured to be the same as linker script setup. This change
updates the Keil uVision project for Nuvoton Numaker-PFM-M2351
to use the variables exported from the linker script. This ensures
that the MPU setup never goes out of sync with linker script.
Earlier we were using hard-coded addresses for MPU setup which
were ensured to be the same as linker script setup. This change
updates the Keil Simulator demo to use the variables exported
from the linker script. This ensures that the MPU setup does not
go out of sync with linker script.
IAR produces some warnings which can not be fixed in the source code because
then other compilers start generating warnings. We suppressed those warnings
in the project file before. This change moves the warning suppression from
project files to portmacro.h.
Update RISC-V ports so the interrupt stack is set to a known value before the scheduler is started if the interrupt stack is statically defined rather than re-using the main.c() stack.
Improve commenting in RISC-V GCC port.
Fix IAR RISC-V port so the first task starts with interrupts enabled.
Add references to third party page ref using newlib with FreeRTOS into the tasks.c file in each place newlib is referenced.
Move the position of the traceTASK_DELETE() trace macro in case of use with a memory allocator that writes over freed memory even when inside a critical section.
Efficiency improvement: Make sure xTaskIncrementTick() does not return pdTRUE when the scheduler is locked. This just prevents an unnecessary yield interrupt (unnecessary as it is ignored) when xYieldPending happens to be pdTRUE.
+ Added xTaskCatchUpTicks() which corrects the tick count value after the application code has held interrupts disabled for an extended period.
+ Updated the xTaskResumeAll() implementation so it uses the new xTaskCatchUpTicks() function mentioned above to unwind ticks that were pended while the scheduler was suspended.
+ Various maintenance on the message buffer, stream buffer and abort delay demos.
+ Change type of uxPendedTicks from UBaseType_t to TickType_t to ensure it has same type as variables it is compared to, and therefore also rename the variable xPendingTicks.
+ Correct spelling mistake within a comment that was common to all the ARMv7-M ports.
The macro taskRESET_READY_PRIORITY checks if the task being removed from the
ready list is the last one and only then resets the top ready priority
by calling portRESET_READY_PRIORITY. If we already know that it is the
last ready task being removed then there is no need to perform the check
again and the macro portRESET_READY_PRIORITY can be called directly. We were
doing the unnecessary check at two places and this commit fixes them.
This commit also increases the time period of check task to ensure that all
the demo tasks get a chance to run before the check is performed.
We had a copy of ARMCM33_DSP_FP_TZ_config.txt file within the project directory
and it used to get outdated with each release of MDK because of non-backward
compatible changes in MDK. This change removes the copy in the project and
instead uses the one shipped with the MDK installation.
portHAS_STACK_OVERFLOW_CHECKING was getting defined too late before
being used in portable.h for the platforms that do not have stack
overflow checking registers. This commit ensures that it is defined
before it is used.
tskSTATIC_AND_DYNAMIC_ALLOCATION_POSSIBLE was not correctly defined resulting in
dynamically allocated TCB not being freed when MPU was enabled. This commit fixes
the definition to ensure that dynamically allocated RAM (Stack and TCB) is freed
always.
When dynamic allocation is not enabled, vPortFree is not available. The current code used
vPortFree and this resulted in linker error. This commit removes the use of vPortFree when
dynamic allocation is not enabled.
Added the portTASK_FUNCTION_PROTO macros around the timer task, as the macros are already used by the idle task.
Add a PDF of the RISC-V documentation into the repo as the web page is not yet live.
+ Switch positions of the asm functions used to start the kernel and handle traps to enable one to reference to the other.
+ Handle external interrupts (working with Renode emulator).
+ The _sp linker variable is now called __freertos_irq_stack_top.
which was brought into the main download in FreeRTOS V10.0.0. FreeRTOS+TCP can
be configured as a UDP only stack, and FreeRTOS+UDP does not contain the patches
applied to FreeRTOS+TCP.
Update to V2.0.7 of the TCP/IP stack:
+ Multiple security improvements and fixes in packet parsing routines, DNS
caching, and TCP sequence number and ID generation.
+ Disable NBNS and LLMNR by default.
+ Add TCP hang protection by default.
We thank Ori Karliner of Zimperium zLabs Team for reporting these issues.
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.
Ensure tasks that are blocked indefinitely on a direct to task notification return their state as eBlocked, previously was returned as eSuspended - making its behaviour consistent with event objects.
Fix typo in stream_buffer.c where "size_t xBytesAvailable ); PRIVILEGED_FUNCTION" had the semicolon in the wrong place.
Add testing of Stream Buffers to the AbortDelay.c tests.
Guard inclusion of C code when FreeRTOSConfig.h is included from an assembly file in the ARM7_LPC2129_IAR demo.
Fix minor typos in the Windows demo comment blocks.
Update the MingW/Eclipse project to add a code coverage build configuration in addition to the existing Debug build configuration.
Update StreamBufferDemo.c so functions are called directly, rather than via configASSERT(), so their code coverage can be measured when configASSERT() is not defined.
In the Win32 port, replace the call to TerminateProcess() in vPortEndScheduler() with exit( 0 ) - which triggers the writing of the code coverage data to the disk.
Fix bug in ucStreamBufferGetStreamBufferType() - which is only used by the Percepio trace tool.
Update the line within vTaskStartScheduler() that was setting xTickCount to 0 to instead set it to configINITIAL_TICK_COUNT.
Update queue code to allow an overwrite operation on a queue that is in a queue set, and add prvTestQueueOverwriteWithQueueSet() to test function.
Update Eclipse Win32 project to bring it closer the the Visual Studio equivalent.
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().
Correct alignment issue in GCC Cortex-R port that was preventing full floating point usage in interrupts (other ports will be updated likewise).
Update the UltraScale R5 demo to test the GCC Cortex-A9 port layer modification mentioned on the line above.
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.
Add an MPU demo that uses the Keil simulator that also uses the Keil compiler.
Correct a few version numbers for files recently added to the repository.
Add RVDS ARM Cortex-M4F MPU port.
Increase the size of each buffer allocated to pbufs in the Microblaze lwIP demo to prevent pbufs chaining.
Use _start as the top of the stack for each Microblaze task, rather than NULL, as NULL was causing the Xilinx SDK to try and unwind the stack too far.
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.
+ Added xPortIsInsideInterrupt() to RVDS ARM CM4F port - the same will get added to other ports in time.
Demo application code:
+ Added first pass Microchip CEC1302 demo for Keil.
+ Harden the new StaticAllocation.c standard demo tasks against integer promotion rules causing problems on 16-bit architectures.
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.
Move structures used for static allocation of tasks and queues into FreeRTOS.h from their individual API header files.
Add SAME70 Xplained Atmel Studio project.
Update SAMV71 Atmel Studio project to use Studio 7.
Revert some changes to GenQTest.c standard demo task which only function correctly when a queue registry was used.
Minor change to xQueueGenericReceive() to catch the extreme case of data being placed into a queue between a task timing out and leaving the xQueueGenericReceive() function.
Added xSemaphoreGetCount() macro.

+ Introduced xTaskCreateStatic() to allow tasks to be created without any dynamic memory allocation.
+ When a task notification is used to unblock a task from an ISR, but the xHigherPriorityTaskWoken parameter is not used, then pend a context switch to occur during the next tick interrupt.
Demo application changes:
+ Updated TaskNotify.c to test the case where a task is unblocked by an ISR, but does not use its xHigherPriorityTaskWoken parameter.
+ Updated the Win32 MSVC project to test statically allocated tasks being created and deleted.
+ Introduced StaticAllocation.c standard demo task.
+ Previously, if a task was deleted, the memory allocated to the task by the RTOS was freed in the Idle task. Now if a task deletes another task the memory is freed immediately. The idle task is however still responsible for freeing the memory when a task deletes itself.
+ Added pcQueueGetQueueName() function to return the name of a queue from its handle, assuming the queue is registers.
Demo application:
+ Update GenQTest to exercise the new pcQueueGetQueueName() function.
+ Delete workspaces from old Eclipse examples, leaving just the projects.
+ Rework comments in the MSVC simply blinky demo.
+ Updated all ARM Cortex-M0 ports to include an additional ISB instruction as the scheduler is started.
Demo app files:
+ Fixex build issues in XMC1000 demos.
+ heap_1.c and heap_2.c now support configAPPLICATION_ALLOCATED_HEAP (heap_4.c already did) which allows the heap to be placed by the user rather than the linker.
Demo app changes:
+ SAMD20 project has been updated to use Atmel Studio 7.
+ 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.

Demo apps:
+ Demo/Rename the CORTEX_R4F_T_GCC_IAR_ARM directory to just Rename the CORTEX_R4F_T_GCC_IAR.
+ Add IAR project for the RX113.
+ Add RX231 e2studio projects for the RX231.
- Remove configASSERT() if a queue cannot be created, malloc failed hook will be called anyway.
Demo apps:
- RZ/T blinky demo working, but still lots to do to improve the port.
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.
- Back out changes that allow mutexes to be given from a semaphore after tests showed issues that would not be fast to fix.
Demo projects:
- Update the Microblaze Kintex 7 project and BSP to use version 2015.2 of the Xilinx SDK.
Zynq ZC702 demo application:
Update the memcpy, memset and memcmp implementations so they don't err with -O3 optimisation.
Update to use the 2015.2 version of the SDK.
Kernel changes:
- Remove an assert that was preventing xQueueSendFromISR() being used to give a mutex from an ISR (mutexes cannot be given using xSemaphoreGiveFromISR()).
- Introduce xTaskNotifyAndQueryFromISR() as the interrupt safe version of xTaskNotifyAndQuery().
Common demo task changes:
- Update IntSemTest.c to prove the theory that it is safe to give a mutex type semaphore from an interrupt using xQueueSendFromISR() instead of xSemaphoreGiveFromISR().
- Update TaskNotify.c to test the new xTaskNotifyAndQuery() from ISR fuction.
Add additional NOPs as required by hardware manual.
Microblaze:
Previously a task inherited the exception enable state from the context from which xTaskCreate() was called. Now tasks all have exceptions enabled if they are enabled in the hardware.
Windows/GCC:
Improve the implementation of portGET_HIGHEST_PRIORITY.
Common code:
Simplify the pointer use in xQueueGenericCreate()
Demo apps:
Remove jpg images that were used to create web pages.
Fix capitalisation issues in some demos where some header files are incldued with the wrong case, preventing building on Linux.
Remove the Microblaze demos that are using obsolete tools.
Update main_blinky for the Windows port demo to include a software timer example.
Windows port: Add code to ensure Windows threads are truely suspended before resuming another thread.
Typo correction to the task notification standard demo task.
Correct case of some include file names to fix build issues on Linux.
+ The timer task now blocks indefinitely if there are no timers active, allowing eTaskConfirmSleepModeStatus to return eNoTasksWaitingTimeout when configUSE_TIMERS is set to 1.
+ The next unblock time is calculated automatically after a task unblocks when waiting for a notification, allowing deep sleep to be entered earlier.
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.
Exclude the entire croutine.c file when configUSE_CO_ROUTINES is 0.
New ports:
Added Cortex-M7 IAR and Keil port layers that include a minor errata workaround r0p1 Cortex-M7 devices.
Added Cortex-M4F port layer for CCS.
New demo applications:
Added demo application for STM32F7.
Added demo application for SAMv71.
+ Added mtCOVERAGE_TEST_DELAY() macro to facilitate getting better code coverage during testing.
+ Update prvNotifyQueueSetContainer() so it does not call xTaskRemoveFromEventList() if it is called from an interrupt, and the queue is locked.
Demo apps:
Added QueueSetPolling.c/h demo/test functions.
+ Added vTimerSetTimerID() to compliment vTimerGetTimerID(). Now the timer ID can be used as timer local storage.

PIC24/dsPIC port:
+ Added NOP after disable interrupt instruction.
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.
+ Do not attempt to free the stack of a deleted task if the stack was statically allocated.
+ Introduce configUSE_LIST_DATA_INTEGRITY_CHECK_BYTES - which optionally writes known values into the list and list item data structures in order to assist with the detection of memory corruptions.
Microblase port:
+Change occurrences of #if XPAR_MICROBLAZE_0_USE_FPU == 1 to #if XPAR_MICROBLAZE_0_USE_FPU != 0 as the value can also be 2 or 3.
Demo app modifications:
+ Update Zynq project to use the 2014.4 tools and add in tests for the new task notification feature.
+ Update SAM4S project to include tests for the new task notification feature.
+ Fix a few compiler warnings.
+ Add TickType_t specific critical sections so critical sections are not used when accessing the tick count in cases where the access is atomic (32-bit tick count, 32-bit architecture).
+ 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.
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.
+ Update the RZ IAR project so it targets the RZ RSK rather than custom hardware.
+ Update the RZ ARM/DS-5 project so it targets the RZ RSK rather than custom hardware.
+ Updated RX64M demos to use the new iodefine.h naming.
Cortex-A9 port related:
+ Update IAR, ARM and GCC Cortex-A9 port layers to include a 'task exit error' function which is called if a task attempts to incorrectly exit its implementing function.
+ Moved the instruction which switches into system mode out of the restore context macro, as it is only needed when starting the first task.
Core kernel files related:
+ Ensure there are no references to the mutexes held count when mutexes are excluded from the build.
- Add additional tests to GenQTest.c to test the updated priority inheritance mechanism.
- Slightly increase some delays in recmutex.c to prevent it reporting false errors in high load test cases.
SAMA5D3 Xplained IAR demo:
- Remove space being allocated for stacks that are not used.
- Remove explicit enabling of interrupts in ISR handers as this is now done from the central ISR callback before the individual handers are invoked.
- Reduce both the allocated heap size and the stack allocated to each task.
- Enable I cache.
- Slight improvement to the save context macro.
- Remove some #warning remarks.
- Enable interrupts before calling the ISR handler rather than in the ISR handler.
- Add in the assert when a task attempts to exit its implementing function without deleting itself.
- Remove obsolete code from the context switch asm code (obsoleted by the fact that there is no mask register).
- Attempt to make code more generic by using definitions for additional register addresses.
- Add full interrupt nesting tests.
- Add additional critical section/context switching tests.
- Set interrupt priorities so everything can run at once without any software watchdog errors.
- Re-enable interrupts in each IRQ handler.
- Add in run-time stats.
Add additional asserts to the Keil CM3 and CM4F ports (other CM3/4 ports already updated).
