- This is a KMS driver for emulated cirrus device in qemu.
- It is *NOT* intended for real cirrus devices. This requires
- the modesetting userspace X.org driver.
- Cirrus is obsolete, the hardware was designed in the 90ies
- and can't keep up with todays needs. More background:
- https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/
- 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)
