Hi all, this patch series introduces support for running Linux on top of Xen inside a virtual machine with virtio devices (nested virt scenario). The problem is that Linux virtio drivers use virt_to_phys to get the guest pseudo-physical addresses to pass to the backend, which doesn't work as expected on Xen. Switching the virtio drivers to the dma APIs (dma_alloc_coherent,

Changes in v6: - check for dev->dma_mask being NULL in dma_capable; - update the comments and the hypercalls structures; - add a xen_dma_info entry to the rbtree in xen_swiotlb_alloc_coherent to keep track of the new mapping. Free the entry in xen_swiotlb_free_coherent; - rename xen_dma_seg to dma_info in xen_swiotlb_alloc/free_coherent to avoid confusions; - introduce and export xen_dma_ops; - call xen_mm_init from as arch_initcall; - call __get_dma_ops to get the native dma_ops pointe...

Hi, I''m doing some testing on Ubuntu 12.04 Alpha. All sounds comes out as static on the Dom0 system. (I can PCI passthrough the audio card to a DomU and that works). Native sound works fine. Linux kronos 3.2.0-8-generic-pae #15-Ubuntu SMP Wed Jan 11 15:34:57 UTC 2012 i686 i686 i386 GNU/Linux Here is the "ubuntu-bug audio" generated report:

Hi, This is third approach (complete this time) for replacing struct dma_attrs with unsigned long. The main patch (2/45) doing the change is split into many subpatches for easier review (3-43). They should be squashed together when applying. *Important:* Patchset is *only* build tested on allyesconfigs: ARM, ARM64, i386, x86_64 and powerpc. Please provide reviewes and tests for other
