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.
