US Patent:
20040215847, Oct 28, 2004
Filed:
Apr 25, 2003
Appl. No.:
10/424198
Inventors:
Shelly Dirstine - Rochester MN, US
Naresh Nayar - Rochester MN, US
Gregory Nordstrom - Pine Island MN, US
Assignee:
INTERNATIONAL BUSINESS MACHINES CORPORATION - ARMONK NY
International Classification:
G06F003/00
US Classification:
710/038000
Abstract:
Methods, systems, and articles of manufacture for communicating with an I/O processor (IOP) are provided. Polling of message queue pointers is utilized to detect the occurrence of certain message queue related events, rather than rely on interrupts generated by the IOP. The polling may decrease the disruptive effects of IOP generated interrupts. In an effort to minimize the latency associated with detecting IOP related events, the polling may be initiated frequently by an operating system task dispatcher. In an effort to minimize context switches, the task dispatcher may schedule the processing of upstream messages detected while polling to coincide with naturally occurring task swaps.
