Hello,This is the 6th revision of the vfio-user client implementation. It is the first patch series (the previous revisions were RFCs) First of all, thank you for your time reviewing the RFC versions. The vfio-user framework consists of 3 parts: 1) The VFIO user protocol specification. 2) A client - the VFIO device in QEMU that encapsulates VFIO messages and sends them to the server. 3) A server - a remote process that emulates a device. This patchset implements parts 1 and 2. The libvfio-user project (https://github.com/nutanix/libvfio-user) can be used by a remote process to handle the protocol to implement the third part. We also have upstreamed a patch series that implement a server using QEMU.
