[Qemu-devel] vhost-user breaks after 96a3d98.

Hi, While I was testing vhost-user using OVS 2.5 and DPDK 2.2.0 in the host and testpmd dpdk 2.2.0 in the guest, I found that the commit below breaks the environment and no packets gets into the guest. dpdk port --> OVS --> vhost-user --> guest --> testpmd ^--- drops

[Qemu-devel] [PATCH V4 04/10] exec: introduce address_space_get_iotlb_entry()

This patch introduces a helper to query the iotlb entry for a possible iova. This will be used by later device IOTLB API to enable the capability for a dataplane (e.g vhost) to query the IOTLB. Cc: Paolo Bonzini Cc: Peter Crosthwaite Cc: Richard

[Qemu-devel] [PATCH V4 00/10] vhost device IOTLB support

Hi all: As the userspace vitio driver became popular, more and more request were received for secure DMA environemt (DMAR). So this series tries to make DMAR works for virtio/vhost. The idea is let virtio/vhost co-work with userspace iommu implememtation. This is done through: - for virtio, when

[Qemu-devel] [PATCH V4 01/10] virtio: convert to use DMA api

Currently, all virtio devices bypass IOMMU completely. This is because address_space_memory is assumed and used during DMA emulation. This patch converts the virtio core API to use DMA API. This idea is - introducing a new transport specific helper to query the dma address space. (only pci
