xf86-video-fbturbo

Xorg DDX driver for ARM devices (Allwinner, RPi and others)

Video driver, primarily optimized for the devices powered by the Allwinner SoC (A10, A13, A20). It can use some of the 2D/3D hardware acceleration features. And because this driver is based on xf86-video-fbdev (with none of the original features stripped), it actually supports all the same hardware as xf86-video-fbdev. Essentially, xf86-video-fbturbo can be just used as a drop-in replacement and run on practically any Linux system. There will be no real difference on x86, but any ARM based system should see better performance thanks to some additional optimizations (the elimination of ShadowFB layer, ARM NEON/VFP code for dealing with uncached framebuffer reads, automatic backing store management for faster window moves).
