Mapping a Virtual Address to PCI Bus Address
When a particular host of one of the root nodes becomes connected to the specified switch, a PCI Configuration Master (PCM), residing in one of the root nodes, is operated to enter a destination identifier or DID into the table. The DID is then appended as an address component, to ...
PCI load/store operations and DMA operations are implemented via work queue pairs in a message-passing, queue-oriented bus architecture. PCI address space is divided into segments and, each segment, in turn, is divided into regions. A separate work queue is assigned to each segment. A first ...
