The write-up below is the first draft of a proposal for how the kernel can expose platform devices to user space using vfio. In short, I'm proposing a new ioctl VFIO_DEVICE_GET_DEVTREE_INFO which allows user space to correlate regions and interrupts to the corresponding device tree node structure that is defined for most platform devices.
