Re: [libvirt] summary of current vfio mdev upstreaming status

Hi all, In order to have a clear understanding about the VFIO mdev upstreaming status, I'd like to summarize it. Please share your opinions on this, and correct my misunderstandings. The whole vfio mdev series can be logically divided into several parts, they work together to provide the mdev support.

PART 1: mdev core driver [task] - the mdev bus/device support - the utilities of mdev lifecycle management - the physical device register/unregister interfaces [status] - basically agreed by community PART 2: vfio bus driver for mdev [task] - interfaces with vendor drivers - the vfio bus implementation [status] - basically agreed by community PART 3: iommu support for mdev [task] - iommu support for mdev [status] - Kirti's v7 implementation, not yet fully reviewed PART 4: sysfs interfaces for mdev [task] - define the hierarchy of minimal sysfs directories/files - check the validity from vendor drivers, init/de-init them [status] - interfaces are in discussion PART 6: Documentation [task] - clearly document the architecture and interfaces - coding example for vendor drivers [status] - N/A What I'm curious here is 'PART 4', which is needed by other parts to perform further steps, is it possible to accelerate the process somehow? :-) -- Thanks, Jike -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
