Interrupt Handling Flow Change to Prevent Deadlock
- Previously the End of Interrupt (EOI) message was
sent after the registered interrupt handler completed
handling of the defect. Instead of this, now the INTRP
will immediately mask the current interrupt source and
issue the HW EOI to allow other interrupt sources to
present.
- Later when the registered interrupt handler sends INTRP
its EOI message the INTRP will unmask the source and
issue the necessary HW EOI to fully clear the interrupt
