mthca use of dma_sync_single is bogus

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,...

This I don't get - if you do lock down long term mappings performance of the actual get_user_page...

Re: [Xen-smartio] Problem with infiniband on Xen domU

...ise. I was able to get up Dom0 to work with infiniband, but not DomU. I am using Xen 3.0.2 with vmlinuz-2.6.16-xen and initrd-2.6.16-xen.img for DomU kernel and ram image respectively. I am getting the error of "Unknown symbol in module" when i am trying to insert infiniband modules ib_mthca.ko and ib_umad.ko to domU kernel. I made sure that the kernel was configured with infiniband support. However, the dmesg output does not show that domU recognized infiniband hardware at bootup. Should I be specifying anything about infiniband in domain config file? Any help very much appreciated,...
