Abstract
Sideband device management bus messages are filtered using software operations in order to minimize dropped messages and to maintain the bus in an operable state. Redundant sideband device management buses are utilized in order to provide fail-over transmission of messages in scenarios where one of the buses becomes inoperable. Multi-packet messages are transmitted to managed devices via the sideband bus connections. If an inoperable state is detected in a sideband bus connection during transmission of a multi-packet message, the portion of the multi-packet message not received by the managed device is transmitted via a redundant sideband bus connection with the managed device. Software filtering of bus transactions utilizes a circular DMA buffer for storing all incoming transactions. Transactions of interest are copied to buffers associated with specific endpoints for processing.
