This is a KMS driver for the virtual Graphics Card used in
Virtual Box virtual machines.

Although it is possible to build this driver built-in to the
kernel, it is advised to build it as a module, so that it can
be updated independently of the kernel. Select M to build this
driver as a module and add support for these devices via drm/kms
