Yes, but all scsiport calls have to be done from within the context of
the scsiport code. Aside from the request processing path where you get
a new srb (scsi request block) to process, you have two choices - the
isr, and a timer callback. Performance with the timer callback is
horrible, for obvious reasons. An isr has to be hooked to an actual irq.
Therein lies the problem...
The more I read about this the more I find other people looking for the
same sort of solution... I may have to abandon the whole scsiport idea,
which would be a shame.
Thanks
James
