I'm currently using CentOS 5.5 with Xen 4.0.1 but open for any recommendation on different linux dist. The first blocking issue that I have is my CX2 doesn't have the SR-IOV extended capability in the PCI config dump as mentioned in the specification. What are the additional firmware/driver that is required in order to have the SR-IOV support in CX2? If SR-IOV is currently not supported, how can I enable PCI-bypass for CX2 in Xen? 02:00.0 InfiniBand: Mellanox Technologies MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE] (rev b0) Subsystem: Mellanox Technologies Device 0017 Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at fbd00000 (64-bit, non-prefetchable) [size=1M] Memory at f9800000 (64-bit, prefetchable) [size=8M] Capabilities: [40] Power Management version 3 Capabilities: [48] Vital Product Data Capabilities: [9c] MSI-X: Enable+ Count=256 Masked- Capabilities: [60] Express Endpoint, MSI 00 Capabilities: [100] Alternative Routing-ID Interpretation (ARI) Kernel driver in use: mlx4_core Kernel modules: mlx4_core Thanks, Wei Lin -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
