|
* This is the list implementation used by the scheduler. While it is tailored
|
|
* heavily for the schedulers needs, it is also available for use by
|
|
* application code.
|
|
*
|
|
* list_ts can only store pointers to list_item_ts. Each ListItem_t contains a
|
|
* numeric value (xItemValue). Most of the time the lists are sorted in
|
|
* descending item value order.
|
|
*
|
|
* Lists are created already containing one list item. The value of this
|
|
* item is the maximum possible that can be stored, it is therefore always at
|
|
* the end of the list and acts as a marker. The list member pxHead always
|
|
* points to this marker - even though it is at the tail of the list. This
|
|
* is because the tail contains a wrap back pointer to the true head of
|
|
* the list.
|
|
*
|
|
* In addition to it's value, each list item contains a pointer to the next
|
|
* item in the list (pxNext), a pointer to the list it is in (pxContainer)
|
|
* and a pointer to back to the object that contains it. These later two
|
|
* pointers are included for efficiency of list manipulation. There is
|
|
* effectively a two way link between the object containing the list item and
|
|
* the list item itself.

* The list structure members are modified from within interrupts, and therefore
|
|
* by rights should be declared volatile. However, they are only modified in a
|
|
* functionally atomic way (within critical sections of with the scheduler
|
|
* suspended) and are either passed by reference into a function or indexed via
|
|
* a volatile variable. Therefore, in all use cases tested so far, the volatile
|
|
* qualifier can be omitted in order to provide a moderate performance
|
|
* improvement without adversely affecting functional behaviour. The assembly
|
|
* instructions generated by the IAR, ARM and GCC compilers when the respective
|
|
* compiler's options were set for maximum optimisation has been inspected and
|
|
* deemed to be as intended. That said, as compiler technology advances, and
|
|
* especially if aggressive cross module optimisation is used (a use case that
|
|
* has not been exercised to any great extend) then it is feasible that the
|
|
* volatile qualifier will be needed for correct optimisation. It is expected
|
|
* that a compiler removing essential code because, without the volatile
|
|
* qualifier on the list structure members and with aggressive cross module
|
|
* optimisation, the compiler deemed the code unnecessary will result in
|
|
* complete and obvious failure of the scheduler. If this is ever experienced
|
|
* then the volatile qualifier can be inserted in the relevant places within the
|
|
* list structures by simply defining configLIST_VOLATILE to volatile in
|
|
* FreeRTOSConfig.h (as per the example at the bottom of this comment block).
|
|
* If configLIST_VOLATILE is not defined then the preprocessor directives below
|
|
* will simply #define configLIST_VOLATILE away completely.
|
|
*
|
|
* To use volatile list structure members then add the following line to
|
|
* FreeRTOSConfig.h (without the quotes):
