This little series adds three drivers, for demo-ing and testing vfio display interface code. There is one mdev device for each interface type (mdpy.ko for region and mbochs.ko for dmabuf). mdpy-fb.ko is guest driver for mdpy.ko (guest driver is not required, without guest driver mdpy.ko simply shows a static test image). mbochs.ko is compatible with bochs-drm.ko on the guest side. v2: - all: various codestyle / checkpatch cleanups. - mdpy-fb: use pci_info() & friends. - mdpy,mbochs: add read/write support for memory bars. - mdpy: get a pci id from qemu range, use that. - mdpy: wrap pci config space registers into vandor capability.
