This document lists the optional platform interrupt controller API that
|
||
|
|
abstracts the runtime configuration and control of interrupt controller from the
|
||
|
|
generic code. The mandatory APIs are described in the `porting guide`__.

Function: unsigned int plat_ic_get_running_priority(void); [optional]

Argument : void

Return : unsigned int
|

|

|
|
This API should return the priority of the interrupt the PE is currently
|
||
|
|
servicing. This must be be called only after an interrupt has already been
|
||
|
|
acknowledged via. ``plat_ic_acknowledge_interrupt``.
|
||
|
|
|
||
|
|
In the case of ARM standard platforms using GIC, the *Running Priority Register*
|
||
|
|
is read to determine the priority of the interrupt.
