US Patent:

61733415, Jan 9, 2001

Filed:

Aug 26, 1998

Appl. No.:

9/140040

Inventors:

Theodore F. Emerson - Houston TX
Christopher J. McCarty - Spring TX

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

G06F 1300
G06F 300

US Classification:

710 8

Abstract:

A computer system with an Intelligent Input/Output architecture having a plug-and-play control mechanism for assigning and controlling one or more adapters. The computer system comprises at least one host processor for executing a host operating system, the host processor disposed on a host bus, an input/output (I/O) bus operably coupled to the host bus via a host-to-bus bridge, and a plurality of peripheral devices or adapters operably connected to the I/O bus for transferring data in I/O transactions controlled by an IOP resource. Initially, a selected adapter is defaulted to an "assigned" state without changing the interrupt routing associated with the adapter. Upon detecting the presence of a driver module that is executable on the IOP, the assigned adapter is marked as "controlled" and the interrupt routing is configured to deliver interrupts to the IOP. Subsequently, the controlled adapter is rendered "hidden" from the host operating system.

Abstract:

A system for hiding computing devices on a computer bus comprising a computer memory for storing information pertaining to computing devices, a device proxy agent for reserving memory for storing information pertaining to hidden devices and an IOP, which in conjunction with the device proxy agent, assigns the memory space assigned to the device proxy agent to hidden devices. A section of memory is allocated as memory address space for the computer bus. A first portion of the allocated memory address space is assigned to non-hidden computing devices and a second portion of the allocated memory address space is assigned to the device proxy agent. The IOP in conjunction with the device proxy agent assigns the memory address space assigned to the device proxy agent to the hidden devices.
