psif (4D)

Name

psif - PCIe Scalable System Interface (PSIF) and Virtual Function InfiniBand (IB) Driver

Description

The psif driver is an IB Architecture-compliant implementation of a host channel adapter (HCA), which operates on Oracle's Infiniband HCA device. These cards are PCIe I/O bus specification compliant. The HCA supports the link and physical layers of the InfiniBand specification, and the driver supports the transport layer.

The psif driver also supports Virtual Functions of HCA when the SR-IOV capability of the HCA is enabled.

The psif driver interfaces with the InfiniBand transport framework (IBTF) and provides an implementation of the channel interfaces that are defined by the framework. The psif driver also enables management applications and agents to access the IB fabric.
