Routine Description:
|
|||
|
|
|
|||
|
|
This routine is used to request a software interrupt to the
|
|||
|
|
system. Also, this routine calls the SSC function
|
|||
|
|
SscGenerateInterrupt() to request the simulator to deliver
|
|||
|
|
the specified interrupt. As a result, the associated bit in
|
|||
|
|
the EIRR will be set.
|
|||
|
|
|
|||
|
|
Arguments:
|
|||
|
|
|
|||
|
|
RequestIrql - Supplies the request IRQL value
|
|||
|
|
|

|
Return Value:

|||
|

|
|||
|
|
None.

Routine Description:

|
|
This routine is used to clear a possible pending software interrupt.

|

The kernel has already cleared the corresponding bit in the EIRR.

|
|
The support for this function is optional, depending on the external

interrupt control.
