A mechanism for enumerating Peripheral Component interconnect (PCI) Express (PCIe) devices within a data processing system is provided. Responsive to a reset of the data processing system, Peripheral Component interconnect (PCI) enumeration information for a set of PCIe devices coupled to the data processing system is read from a processor register. The PCI enumeration information is stored in an address space. PCI enumeration of the PCIe devices is skipped and the PCI enumeration information stored in the address space is presented to the operating system (OS) of the data processing system in order that the OS maintaining the PCIe devices using the PCI enumeration information.

Intelligent certificate discovery in physical and virtualized networks

A mechanism is provided in a data processing system for transferring failure data from a processing unit to a management device. In response to detecting a failure of the processing unit, a computing device within the data processing system gathers failure information from machine check registers of the processing unit. The computing device generates a time stamp command communicating a time and date of the failure information and sends the time stamp command to the management device. The computing device generates at least one error data command communicating error data derived from the failure information and sends the at least one error data command to the management device.
