  • Publication number: 20190286608
    Abstract: According to an embodiment, a system, a method, and/or a computer program product is provided to allow a choice of allocating resources of a processor host bridge (PHB) at initial setup of a computer system to a group of peripheral component interconnect express (PCI-E) slots via a PCI-E switch, or alternatively to allocate resources of the PHB directly to a single PCI-E slot. The system may include a PHB, a first switch connected to the PHB, where the first switch is a simple circuit, a second switch connected to the first switch, where the second switch is a simple circuit, a PCI-E switch connected to the first switch and connected to the second switch, and a first PCI-E slot connected to the second switch.

  • Patent number: 10387349
    Abstract: Dynamically bypassing a peripheral component interconnect (PCI) switch including preparing, during run time, a PCI host bridge for disconnection from the PCI switch, wherein the PCI host bridge is connected to a first PCI slot via the PCI switch; toggling, during run time, an electrical switch, wherein toggling the electrical switch bypasses the PCI switch and creates a direct connection between the PCI host bridge and the first PCI slot; and configuring, during run time, the PCI host bridge for the direct connection between the PCI host bridge and the first PCI slot.

  • Patent number: 9697166
    Abstract: A method, system and computer program product are provided for implementing health check for optical cable attached Peripheral Component Interconnect Express (PCIE) enclosures in a computer system. System firmware is provided for implementing health check functions. One or more optical cables are connected between a host bridge and a PCIE enclosure. A PCIE link to the PCIE enclosure is reset responsive to a predefined event. After a set delay, a PCIE link health check is performed verifying PCIE link width and speed.
