It seems the problems running mthca in a Xen domU have uncovered a bug in mthca: mthca uses dma_sync_single in mthca_arbel_write_mtt_seg() and mthca_arbel_map_phys_fmr() to sync the MTTs that get written. However, Documentation/DMA-API.txt says: void dma_sync_single(struct device *dev, dma_addr_t dma_handle, size_t size, enum dma_data_direction direction) synchronise a single

Greetings, Following patches are intended to support SR-IOV capability in the Linux kernel. With these patches, people can turn a PCI device with the capability into multiple ones from software perspective, which will benefit KVM and achieve other purposes such as QoS, security, and etc. Changes from v5 to v6: 1, update ABI document to include SR-IOV sysfs entries (Greg KH) 2, fix two coding
