In linux kernel since version 3.1 (release Date: 2011-10-24)  
This is a KMS driver for emulated cirrus device in qemu.
It is *NOT* intended for real cirrus devices. This requires
the modesetting userspace driver.

Cirrus is obsolete, the hardware was designed in the 90ies
and can't keep up with todays needs. More background:

Better alternatives are:
- stdvga (DRM_BOCHS, qemu -vga std, default in qemu 2.2+)
- qxl (DRM_QXL, qemu -vga qxl, works best with spice)
- virtio (DRM_VIRTIO_GPU), qemu -vga virtio)
