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Cirrus is obsolete, the hardware was designed in the 90ies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:

|

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)
