| 7 | This is a KMS driver for emulated cirrus device in qemu. |
| 8 | It is *NOT* intended for real cirrus devices. This requires |
| 9 | the modesetting userspace X.org driver. |
| 10 | |
| 11 | Cirrus is obsolete, the hardware was designed in the 90ies |
| 12 | and can't keep up with todays needs. More background: |

| 15 | Better alternatives are: |
| 16 | - stdvga (DRM_BOCHS, qemu -vga std, default in qemu 2.2+) |
| 17 | - qxl (DRM_QXL, qemu -vga qxl, works best with spice) |
| 18 | - virtio (DRM_VIRTIO_GPU), qemu -vga virtio) |
