MSOP_INTR_TASKPRI(D2psm)
MSOP_INTR_TASKPRI --
change the task priority for a CPU
Synopsis
void pfxintr_taskpri(unsigned int taskpri)
Description
MSOP_INTR_TASKPRI is called to inform the PSM that
the task priority for the calling CPU has changed. The
task priority is used as a hint to help choose to which CPU
to deliver an interrupt when all else (that is, task masking) is equal. CPUs
with lower task priority values are preferred. Task priority and task
priority numbering are unrelated to interrupt masking, ordered or otherwise.
The PSM may ignore the task priority, but its use is recommended if
it can be implemented easily.
The task priority taskpri must not be greater than
MSPARAM_INTR_TASKPRI_MAX. See
os_set_msparam(D3psm)
for details.
Arguments
taskpri-
the priority level of the interrupt controller
Return values
None.
Usage
Hardware applicability
Platforms that have a priority-based interrupt controller.
