Northbridge or host bridge for PowerPC CPU is an Integrated Circuit (IC) for interfacing PowerPC CPU with memory, and Southbridge IC. Some Northbridge also provide interface for Accelerated Graphics Ports (AGP) bus, Peripheral Component Interconnect (PCI), PCI-X, PCI Express, or Hypertransport bus. Specific Northbridge IC must be used for ...
A typical north/southbridge layout (2015) A typical north/southbridge layout (2007) In computing, a northbridge (also host bridge, or memory controller hub) is a microchip that comprises the core logic chipset architecture on motherboards to handle high-performance tasks, especially for older personal computers.
The PCIe Root Complex holds a master copy of a 'Type 1 Configuration Table' that defines the host memory space that is accessible from each Endpoint device. In addition, each PCIe Endpoint device holds a master copy of their own memory space map in the host system memory as a 'Type 0 Configuration Table', this configuration table in each device ...
This provides a convenient development environment for PowerPC-based real-time, embedded systems. Power.org has a Power Architecture Platform Reference (PAPR) that provides the foundation for development of Power ISA-based computers running the Linux operating system. PAPR was released in the fourth quarter of 2006.
QEMU integrates several services to allow the host and guest systems to communicate for example: an integrated SMB server and network-port redirection (to allow incoming connections to the virtual machine). It can also boot Linux kernels without a bootloader. QEMU does not depend on the presence of graphical output methods on the host system.
The mapping of PCI interrupt lines onto system interrupt lines, through the PCI host bridge, is implementation-dependent. Platform-specific firmware or operating system code is meant to know this, and set the "interrupt line" field in each device's configuration space indicating which IRQ it is connected to. PCI interrupt lines are level-triggered.
Using lspci -v, lspci -vv, or lspci -vvv will display increasingly verbose details for all devices.-d [<vendor>]:[<device>] option specifies the vendor and device ID of the devices to display.
HyperTransport also facilitates power management as it is compliant with the Advanced Configuration and Power Interface specification. This means that changes in processor sleep states (C states) can signal changes in device states (D states), e.g. powering off disks when the CPU goes to sleep.
