The first part with refactoring of vdpa_sim has already been merged. The patches are based on Max Gurtovoy's work and extend the block simulator to have a ramdisk behaviour. As mentioned in the v1 there was 2 issues and I fixed them in this series: 1. The identical mapping in the IOMMU used until now in vdpa_sim created issues when mapping different virtual pages with the same physical address. Fixed by patch "vdpa_sim: use iova module to allocate IOVA addresses" 2. There was a race accessing the IOMMU between the vdpasim_blk_work() and the device driver that map/unmap DMA regions. Fixed by patch "vringh: add 'iotlb_lock' to synchronize iotlb accesses" I used the Xie's patch coming from VDUSE series to allow vhost-vdpa to use block devices, and I added get_config_size() callback to allow any device in vhost-vdpa. The series also includes small fixes for vringh, vdpa, and vdpa_sim that I discovered while implementing and testing the block simulator.
