Ethernet over PCIe driver for Inter-Processor Communication

2013-08-22 Thread Saravanan S
Hi All, I have a custom board with four MPC8640 nodes connected over a transparent PCI express switch . In this configuration one node is configured as host(Root Complex) and others as agents(End Point) .Thus the legacy PCI software works fine . However the mainline kernel lacks any stan

Standalone SRIO Driver for Linux

2012-07-12 Thread Saravanan S
Hi , Iam currently working on the GE make DSP230 board consisting of Quad PowerPC8640 nodes interconnected by SRIO with Linux 2.6.34 . However the only way to access the SRIO is through rionet facility . Our requirement is to use the SRIO interconnect without the Ethernet overheads. This wo
