Scsiport Timers

NTDEV
1

If I ask SCSIPort to notify me on a timer, does the timer depend on a DPC to run? i.e., if the
IRQL is DISPATCH_LEVEL in some other context, and stays there, and I take an interrupt
and ask to be notified after some timeout, but the other context never drops the IRQL, will I still be notified?
Or does the SCSIPort timer require a DPC to run?

Thanks,

Yes, this is usual KeSetTimer thing.
SCSIPORT also uses Io timer in the device object for 1-second pinging.
