* Enhanced priority dis-inheritance functionality in the case where a task ↵rtel2017-01-161-28/+153
| | | | | | | | | that caused another task to inherit its priority times out before obtain a mutex. 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2478 1d2547de-c912-0410-9cb9-b8ca96c0e9e2
* Update TaskNotify.c to test the condition where a direct to task ↵rtel2016-11-251-10/+33
| | | | | | | | | | | | | notification is sent to a suspended task. 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2473 1d2547de-c912-0410-9cb9-b8ca96c0e9e2

* Changes to core code and port layer:rtel2016-08-161-19/+8
| | | | | | | | | | | | | | + 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2467 1d2547de-c912-0410-9cb9-b8ca96c0e9e2

* Notes: rtel2016-03-221-569/+532
| | | | | | | | | | | | | | | | | | + 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2428 1d2547de-c912-0410-9cb9-b8ca96c0e9e2

* Prepare for a FreeRTOS V9 release candidate:rtel2016-02-181-41/+41
| | | | | | | | | - 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2417 1d2547de-c912-0410-9cb9-b8ca96c0e9e2
* Core kernel code changes:rtel2016-02-141-15/+122
| | | | | | | + 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". git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2416 1d2547de-c912-0410-9cb9-b8ca96c0e9e2
* FreeRTOS source:rtel2016-02-101-340/+167
| | | | | | | | | - 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2415 1d2547de-c912-0410-9cb9-b8ca96c0e9e2

* Add vTaskGetTaskInfo() function that allows a TaskStatus_t structure to be ↵rtel2016-01-281-80/+263
| | | | | | | | | | | | | returned for an individual task (previously information could only be obtained for all the tasks at once). 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2410 1d2547de-c912-0410-9cb9-b8ca96c0e9e2

| | | | | | | | | | | 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. Demo app changes: Updated countsem.c to test the new xSemaphoreGetCount() macro. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2401 1d2547de-c912-0410-9cb9-b8ca96c0e9e2
* Changes to the FreeRTOS code:rtel2015-12-201-68/+129
| | | | | | | | | | | | + 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2397 1d2547de-c912-0410-9cb9-b8ca96c0e9e2
* FreeRTOS source:rtel2015-12-081-18/+29
| | | | | | | | | | | | + 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2396 1d2547de-c912-0410-9cb9-b8ca96c0e9e2
* Kernel changes:rtel2015-11-201-5/+44
| | | | | | | | | | | | | + 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2393 1d2547de-c912-0410-9cb9-b8ca96c0e9e2

| | | | | | | | | | | | | 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2361 1d2547de-c912-0410-9cb9-b8ca96c0e9e2

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.

| | | | | | | | | | | | | | + 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. git-svn-id: http://svn.code.sf.net/p/freertos/code/trunk@2317 1d2547de-c912-0410-9cb9-b8ca96c0e9e2
