From a5e6e6505f38f7bce1d3576503a2bffff3fa888c Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 11 May 2018 09:05:04 -0600 Subject: sample: vfio bochs vbe display (host device for bochs-drm) Display device, demo-ing the vfio dmabuf display interface (VFIO_GFX_PLANE_TYPE_DMABUF). Compatible enough to qemu stdvga that bochs-drm.ko can be used as guest driver.
