20130159582 | Resource Reservation for an External Device that is Not Available at Startup of a Host Computer - A system and method for reserving resources of a host computer for use by an external device configured to be coupled to an expansion bus of the host computer are described. The host computer may be configured to execute device resource software that operates at a startup of the host computer to reserve one or more resources for the external device. The external device may not be available during the startup of the host computer, e.g., because the external device is not powered on or is not physically connected to the host computer. The device resource software may subsequently detect that the external device becomes available after the startup of the host computer. In response, the device resource software may enable the external device to use the one or more resources that were previously reserved at the startup of the host computer. | 06-20-2013 |
20140372641 | Selectively Transparent Bridge for Peripheral Component Interconnect Express Bus Systems - A selectively transparent bridge facilitates a PCI device presenting itself to the host as a PCI-to-PCI bridge but selectively hiding and isolating hardware from the host bus. PCI configuration may be achieved through the standard PCI Express configuration mechanisms, but instead of configuring devices directly, a configuration processor in the selectively transparent bridge may intercept the configuration packets from the host, and create a virtual configuration to alter how the bus topology appears to the host. Devices are selectively hidden and managed by the configuration processor, resulting in simplified complexity and bus depth. Since the selectively transparent bridge appears to the host as a transparent bridge, no special drivers or resource preallocations are required, although the selectively transparent bridge fully supports special drivers and/or resource preallocations. Devices located/connected downstream of the bridge may therefore function with unmodified drivers. | 12-18-2014 |
20140372657 | Hidden Base Address Register Programming in Peripheral Component Interconnect Express Buses - A mapping and correspondence may be established between a virtual topology and a physical topology of a PCIe subsystem, and a host may be presented with the virtual topology but not the actual physical topology. A semi transparent bridge may couple an upstream host to the PCIe subsystem that includes intermediary bridges and respective PCIe endpoints coupled downstream from the intermediary bridges. The intermediary bridges may be hidden from the host, while the respective PCIe endpoints may be visible to the host. A configuration block may provide to the upstream host, during a setup mode, first memory allocation information corresponding to the intermediary switches, responsive to the upstream host expecting second memory allocation information corresponding to the respective PCIe endpoints. The configuration block may then provide to the upstream host, during a runtime mode, the second memory allocation information, responsive to the upstream host expecting the second memory allocation information. | 12-18-2014 |
20140372741 | Opaque Bridge for Peripheral Component Interconnect Express Bus Systems - A host system may couple to a PCIe subsystem. During setup of the PCIe subsystem, the BIOS in the host system may first be informed that the devices to be coupled are not PCIe devices, and certain amount of memory is required for these devices. The BIOS may therefore not attempt to configure the devices, and may instead allocate the required memory space. When the operating system boots up, it may not attempt to configure the devices, loading a custom driver instead of an existing PCI driver to configure the bus. Once loaded, the custom driver may configure the devices, then inform the OS that there are PCIe devices in the system at the specified addresses, which may cause the OS to load and execute existing PCIe device drivers to operate/use the devices. The proprietary driver may also be used to handle traffic between the PCIe drivers and the OS. | 12-18-2014 |
