- VFIO updates for v4.10 primarily include a new Mediated Device
interface, which essentially allows software defined devices to be
exposed to users through VFIO. The host vendor driver providing
this virtual device polices, or mediates user access to the device.
These devices often incorporate portions of real devices, for
instance the primary initial users of this interface expose vGPUs
which allow the user to map mediated devices, or mdevs, to a
portion of a physical GPU. QEMU composes these mdevs into PCI
representations using the existing VFIO user API. This enables
both Intel KVM-GT support, which is also expected to arrive into
Linux mainline during the v4.10 merge window, as well as NVIDIA
vGPU, and also Channel I/O devices (aka CCW devices) for s390
virtualization support. (Kirti Wankhede, Neo Jia)
- Drop unnecessary uses of pcibios_err_to_errno() (Cao Jin)
- Fixes to VFIO capability chain handling (Eric Auger)
- Error handling fixes for fallout from mdev (Christophe JAILLET)
- Notifiers to expose struct kvm to mdev vendor drivers (Jike Song)
- type1 IOMMU model search fixes (Kirti Wankhede, Neo Jia)
