Hi all: This series tries to support batched IOTLB updating vhost-vdpa. Currently vhost-vdpa accepts userspace mapping via IOTLB API, and it can only forward one mapping to IOMMU or device through IOMMU API or dma_map(). Though set_map() is deisgend to have the capability to pass an rbtree based mapping to vDPA device, it's still be called at least once for each VHOST_IOTLB_UPDATE or

Hi All: This series introduces API for reporing IOVA range. This is a must for userspace to work correclty: - for the process that uses vhost-vDPA directly to properly allocate IOVA - for VM(qemu), when vIOMMU is not enabled, fail early if GPA is out of range - for VM(qemu), when vIOMMU is enabled, determine a valid guest address width Please review. Thanks Jason Wang (4): vdpa:

Hi, Now that virtio-rpmsg endianness fixes have been merged we can proceed with the next step. v4: - add endianness conversions to comply with the VirtIO standard v3: - address several checkpatch warnings - address comments from Mathieu Poirier v2: - update patch #5 with a correct vhost_dev_init() prototype - drop patch #6 - it depends on a different patch, that is currently an RFC -
