+ New feature added: Task notifications.

Browse source 
+ 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.

* - TRACE_STORE_MODE_STOP_WHEN_FULL
* Default is TRACE_STORE_MODE_RING_BUFFER.
*
* With TRACE_RECORDER_STORE_MODE set to TRACE_STORE_MODE_RING_BUFFER, the events are
* stored in a ring buffer, i.e., where the oldest events are overwritten when
* the buffer becomes full. This allows you to get the last events leading up
* to an interesting state, e.g., an error, without having a large trace buffer
* for string the whole run since startup. In this mode, the recorder can run
* "forever" as the buffer never gets full, i.e., in the sense that it always
* has room for more events.
*
* To fetch the trace in mode TRACE_STORE_MODE_RING_BUFFER, you need to first halt the
* system using your debugger and then do a RAM dump, or to explicitly stop the
* recorder using vTraceStop() and then store/upload the trace data using a
* task that you need to provide yourself. The trace data is found in the struct
* RecorderData, initialized in trcBase.c.
*
* Note that, if you upload the trace using a RAM dump, i.e., when the system is
* halted on a breakpoint or by a debugger command, there is no need to stop the
* recorder first.
*
* When TRACE_RECORDER_STORE_MODE is TRACE_STORE_MODE_STOP_WHEN_FULL, the recording is
* stopped when the buffer becomes full. When the recorder stops itself this way
* vTracePortEnd() is called which allows for custom actions, such as triggering
* a task that stores the trace buffer, i.e., in case taking a RAM dump
* using an on-chip debugger is not possible. In the Windows port, vTracePortEnd
* saves the trace to file directly, but this is not recommended in a real-time
* system since the scheduler is blocked during the processing of vTracePortEnd.

/******************************************************************************
* USE_IMPLICIT_IFE_RULES
*
* Macro which should be defined as either zero (0) or one (1).
* Default is 1.
*
* ### Instance Finish Events (IFE) ###
*
* For tasks with "infinite" main loops (non-terminating tasks), the concept
* of a task instance has no clear definition, it is an application-specific
* thing. Tracealyzer allows you to define Instance Finish Events (IFEs),
* which marks the point in a cyclic task when the "task instance" ends.
* The IFE is a blocking kernel call, typically in the main loop of a task
* which typically reads a message queue, waits for a semaphore or performs
* an explicit delay.
*
* If USE_IMPLICIT_IFE_RULES is one (1), the kernel macros (trcKernelPort.h)
* will define what kernel calls are considered by default to be IFEs.
*
* However, Implicit IFEs only applies to blocking kernel calls. If a
* service reads a message without blocking, it does not create a new
* instance since no blocking occurred.
*
* Moreover, the actual IFE might sometimes be another blocking call. We
* therefore allow for user-defined Explicit IFEs by calling
*
* vTraceTaskInstanceIsFinished()
*
* right before the kernel call considered as IFE. This does not create an
* additional event but instead stores the service code and object handle
* of the IFE call as properties of the task.
*
* If using Explicit IFEs and the task also calls an Implicit IFE, this may
* result in additional incorrect task instances.
* This is solved by disabling the Implicit IFEs for the task, by adding
* a call to
*
* vTraceTaskSkipDefaultInstanceFinishedEvents()
*
* in the very beginning of that task. This allows you to combine Explicit IFEs
* for some tasks with Implicit IFEs for the rest of the tasks, if
* USE_IMPLICIT_IFE_RULES is 1.
*
* By setting USE_IMPLICIT_IFE_RULES to zero (0), the implicit IFEs are disabled
* for all tasks. Tasks will then be considered to have a single instance only,
* covering all execution fragments, unless you define an explicit IFE in each
* task by calling vTraceTaskInstanceIsFinished before the blocking call.

* objects such as tasks and queues. This limits the supported number of
* concurrently active objects to 255 of each type (object class).
*
* If set to 1 (one), the recorder uses 16-bit handles to identify kernel
* objects such as tasks and queues. This limits the supported number of
* concurrent objects to 65535 of each type (object class). However, since the
* object property table is limited to 64 KB, the practical limit is about
* 3000 objects in total.
*
* NOTE: An object with a high ID (> 255) will generate an extra event
* (= 4 byte) in the event buffer.
*
* NOTE: Some internal tables in the recorder gets larger when using 16-bit
* handles. The additional RAM usage is 5-10 byte plus 1 byte per kernel object
*, i.e., task, queue, semaphore, mutex, etc.

* TRACE_RECORDER_STORE_MODE
*
* Macro which should be defined as one of:
* - TRACE_STORE_MODE_RING_BUFFER
* - TRACE_STORE_MODE_STOP_WHEN_FULL
* Default is TRACE_STORE_MODE_RING_BUFFER.
*
* With TRACE_RECORDER_STORE_MODE set to TRACE_STORE_MODE_RING_BUFFER, the events are
* stored in a ring buffer, i.e., where the oldest events are overwritten when
* the buffer becomes full. This allows you to get the last events leading up
* to an interesting state, e.g., an error, without having a large trace buffer
* for string the whole run since startup. In this mode, the recorder can run
* "forever" as the buffer never gets full, i.e., in the sense that it always
* has room for more events.
*
* To fetch the trace in mode TRACE_STORE_MODE_RING_BUFFER, you need to first halt the
* system using your debugger and then do a RAM dump, or to explicitly stop the
* recorder using vTraceStop() and then store/upload the trace data using a
* task that you need to provide yourself. The trace data is found in the struct
* RecorderData, initialized in trcBase.c.
*
* Note that, if you upload the trace using a RAM dump, i.e., when the system is
* halted on a breakpoint or by a debugger command, there is no need to stop the
* recorder first.
*
* When TRACE_RECORDER_STORE_MODE is TRACE_STORE_MODE_STOP_WHEN_FULL, the recording is
* stopped when the buffer becomes full. When the recorder stops itself this way
* vTracePortEnd() is called which allows for custom actions, such as triggering
* a task that stores the trace buffer, i.e., in case taking a RAM dump
* using an on-chip debugger is not possible. In the Windows port, vTracePortEnd
* saves the trace to file directly, but this is not recommended in a real-time
* system since the scheduler is blocked during the processing of vTracePortEnd.

* the specified number of events has been observed. This value can be larger
* than the buffer size, to allow for test of the "wrapping around" that occurs
* in ring buffer mode . A negative value (or no definition of this macro)
* disables this feature.
*****************************************************************************/
#define STOP_AFTER_N_EVENTS -1
/******************************************************************************
* USE_IMPLICIT_IFE_RULES
*
* Macro which should be defined as either zero (0) or one (1).
* Default is 1.
*
* ### Instance Finish Events (IFE) ###
*
* For tasks with "infinite" main loops (non-terminating tasks), the concept
* of a task instance has no clear definition, it is an application-specific
* thing. Tracealyzer allows you to define Instance Finish Events (IFEs),
* which marks the point in a cyclic task when the "task instance" ends.
* The IFE is a blocking kernel call, typically in the main loop of a task
* which typically reads a message queue, waits for a semaphore or performs
* an explicit delay.
*
* If USE_IMPLICIT_IFE_RULES is one (1), the kernel macros (trcKernelPort.h)
* will define what kernel calls are considered by default to be IFEs.
*
* However, Implicit IFEs only applies to blocking kernel calls. If a
* service reads a message without blocking, it does not create a new
* instance since no blocking occurred.
*
* Moreover, the actual IFE might sometimes be another blocking call. We
* therefore allow for user-defined Explicit IFEs by calling
*
* vTraceTaskInstanceIsFinished()
*
* right before the kernel call considered as IFE. This does not create an
* additional event but instead stores the service code and object handle
* of the IFE call as properties of the task.
*
* If using Explicit IFEs and the task also calls an Implicit IFE, this may
* result in additional incorrect task instances.
* This is solved by disabling the Implicit IFEs for the task, by adding
* a call to
*
* vTraceTaskSkipDefaultInstanceFinishedEvents()
*
* in the very beginning of that task. This allows you to combine Explicit IFEs
* for some tasks with Implicit IFEs for the rest of the tasks, if
* USE_IMPLICIT_IFE_RULES is 1.
*
* By setting USE_IMPLICIT_IFE_RULES to zero (0), the implicit IFEs are disabled
* for all tasks. Tasks will then be considered to have a single instance only,
* covering all execution fragments, unless you define an explicit IFE in each
* task by calling vTraceTaskInstanceIsFinished before the blocking call.
*****************************************************************************/

/******************************************************************************
* USE_16BIT_OBJECT_HANDLES
*
* Macro which should be defined as either zero (0) or one (1).
* Default is 0.
*
* If set to 0 (zero), the recorder uses 8-bit handles to identify kernel
* objects such as tasks and queues. This limits the supported number of
* concurrently active objects to 255 of each type (object class).
*
* If set to 1 (one), the recorder uses 16-bit handles to identify kernel
* objects such as tasks and queues. This limits the supported number of
* concurrent objects to 65535 of each type (object class). However, since the
* object property table is limited to 64 KB, the practical limit is about
* 3000 objects in total.
*
* NOTE: An object with a high ID (> 255) will generate an extra event
* (= 4 byte) in the event buffer.
*
* NOTE: Some internal tables in the recorder gets larger when using 16-bit
* handles. The additional RAM usage is 5-10 byte plus 1 byte per kernel object
*, i.e., task, queue, semaphore, mutex, etc.

Interrupts that are above the maximum system call priority are keep
permanently enabled, even when the RTOS kernel is in a critical section,
but cannot make any calls to FreeRTOS API functions. If configASSERT()
is defined in FreeRTOSConfig.h then
portASSERT_IF_INTERRUPT_PRIORITY_INVALID() will result in an assertion
failure if a FreeRTOS API function is called from an interrupt that has
been assigned a priority above the configured maximum system call
priority. Only FreeRTOS functions that end in FromISR can be called
from interrupts that have been assigned a priority at or (logically)
below the maximum system call interrupt priority. FreeRTOS maintains a
separate interrupt safe API to ensure interrupt entry is as fast and as
simple as possible. More information (albeit Cortex-M specific) is
provided on the following link:
http://www.freertos.org/RTOS-Cortex-M3-M4.html */
