|
|
* NOTE1:
|
|
* QF_TX_PRIO_OFFSET specifies the number of highest-urgency ThreadX
|
|
* priorities not available to QP active objects. These highest-urgency
|
|
* priorities might be used by ThreadX threads that run "above" QP active
|
|
* objects.
|
|
*
|
|
* Because the ThreadX priority numbering is "upside down" compared
|
|
* to the QP priority numbering, the ThreadX priority for an active object
|
|
* thread is calculated as follows:
|
|
* tx_prio = QF_TX_PRIO_OFFSET + QF_MAX_ACTIVE - qp_prio
|
|
*
|
|
* NOTE2:
|
|
* The maximum number of active objects in QP can be increased to 63,
|
|
* inclusive, but it can be reduced to save some memory. Also, the number of
|
|
* active objects cannot exceed the number of TreadX thread priorities
|
|
* TX_MAX_PRIORITIES, because each QP active object requires a unique
|
|
* priority level. Due to the artificial limitations of the ThreadX demo
|
|
* for Windows, QF_MAX_ACTIVE is set here lower to not exceed the total
|
|
* available priority levels.
|
|
*
|
|
* NOTE3:
|
|
* The ThreadX critical section must be able to nest, which is the case with
|
|
* the tx_interrupt_control() API.
