INPUT/OUTPUT CONTROL DEVICE, INFORMATION PROCESSING APPARATUS, AND CONTROL METHOD OF THE INPUT/OUTPUT CONTROL DEVICE

摘要

A PCIe processing unit is connected to a PCI device. A BDF information extracting unit specifies, in response to an occurrence notification of an error, a PCI device in which the error has occurred. An AER address searching unit detects the AER address that is the storage location of error information related to the error held by the PCI device specified by the BDF information extracting unit. An error information acquiring unit collects error information from the AER address that is stored in the PCI device and that is detected by the AER address searching unit. An interrupt determination unit transmits the error information collected by the error information acquiring unit to a core.

1. An input/output control device connected to a processing unit, the input/output control device comprising:
a specifying unit that specifies, in response to an occurrence notification of an error, a processing unit in which the error has occurred; a detecting unit that detects a storage location of error information related to the error held by the processing unit specified by the specifying unit; a collecting unit that collects the error information from the storage location that is stored in the processing unit and that is detected by the detecting unit; and a transmission unit that transmits the error information collected by the collecting unit to an arithmetic processing device.
