The Linux kernel configuration item CONFIG_DRM_CIRRUS_QEMU
has multiple definitions:
drivers/gpu/drm/tiny/Kconfig
The configuration item CONFIG_DRM_CIRRUS_QEMU:
CONFIG_DRM && CONFIG_PCI && CONFIG_MMU
cirrus
, cirrus
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Cirrus is obsolete, the hardware was designed in the 90ies and can't keep up with todays needs.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)
