Patent ID: 7877643

Claim:
A system within a logical partitioned data processing system for providing a host bridge that implements extended error handling in logical partitioned data processing systems, the system comprising: the host bridge, wherein the host bridge enables extended error handling when all devices coupled below the host bridge implement extended error handling; wherein the host bridge disables extended error handling in the host bridge when at least one of the devices coupled below the host bridge does not implement extended error handling, wherein at least one of the devices is allocated to a first partition, wherein at least one device in the devices coupled below the host bridge is allocated to a second partition, and wherein the host bridge is shared by the first and second partition; the first and second partition is terminated when extended error handling is disabled in the host bridge when an error occurs in one of the devices; and the first and second partitions continue operating when extended error handling is enabled in the host bridge in response to an error occurring in the one of the devices.
