I also notice this in the dom0 dmesg.PCI-DMA: Disabling IOMMU. WARNING more than 4GB of memory but IOMMU not compiled in. WARNING 32bit PCI may malfunction. You might want to enable CONFIG_GART_IOMMU Memory: 5868412k/6071120k available (3553k kernel code, 202040k reserved, 1376k data, 300k init) That is harmless. In fact our SWIOTLB probably is enabled (look at the lines just above the ones you posted). It's because we don't properly (yet) respect the new plug-n-play dma_ops structures in x86_64. I've checked in a temporary fix to remove the above misleading lines. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
