VirtualBox DRM/KMS Graphics Driver Being Prepped For Mainline Kernel
For those using VirtualBox VMs in conjunction with vboxvideo as part of the guest driver collection, it looks like the experience could soon be better. Red Hat's Hans de Goede has been cleaning up the vboxvideo driver for eventual submission into the kernel's staging area. Yes, Red Hat's doing the work but the VirtualBox developers at Oracle at least have blessed the work and promised not to break the user-space ABI in a backwards incompatible manner moving forward.
In cleaning up vboxvideo, Hans de Goede has taken the driver from 52,861 lines of code down to 7,275 lines and then almost half of that remaining portion is OS-independent code for VirtualBox.
Being talked about right now is just vboxvideo but it appears there are plans for cleaning up and mainlining the other VirtualBox guest drivers too. More details via this mailing list post. It will be interesting to see if vboxvideo is accepted for staging in Linux 4.13.
