cyrix - Cyrix video driver
cyrix is an Xorg driver for the Cyrix MediaGX (now Natsemi Geode)
series of processors when using the built in video.
The cyrix driver supports the MediaGX, MediaGXi and MediaGXm
processors, as well as the Natsemi ’Geode’ branded processors. It
supports the CS5510, CS5520, CS5530 and CS5530A companion chips. The
driver supports 4, 8, 15 and 16 bit deep displays with video
compression and acceleration.
The MediaGX run length compresses its shared framebuffer, for the best
performance on a MediaGX machine pick backgrounds that compress well
