gallatin 537bde557a Alter isa interrupt behaviour on alpha. Rather than send a non-specific ... EOI after the ithread runs, send the EOI when we get the interrupt and disable the source. After the ithread is run, the source is renabled. Also, add isa_handle_fast_intr() which handles fast interrupts by sending an EOI after the handler is run. This fixes the chronic missing interrupt problems under heavy NFS load on my UP1000 and should result in greater stability for alphas which route all irqs through an isa pic. Discussed with: jhb, bde (sending non-specific EOIs early was bde's idea)		2000-12-01 22:28:04 +00:00
