Etnaviv is a new open-source project for building a user-space graphics driver for controlling the Vivante GPUs found in some ARM SoCs. The ultimate goal is to create a new Mesa/Gallium3D driver for this graphics core.
At the moment the Etnaviv driver is particularly seeking to support the Vivante GCxxx series of embedded graphics processors. The 3D-capable Vivante GPUs include the GC400, GC500, GC600, GC800, GC1000, GC2000, and GC4000 products. These graphics cores support OpenGL ES 2.0, OpenVG 1.1, EGL 1.4, DirectX 11, and OpenGL 2.1/3.0.
The Vivante GPUs have been found in many ARM SoCs from the low-cost "Chinese tablets." Among the popular devices bearing Vivante graphics include the Google TV, OLPC, CuBox, many Rockchip 2918 tablets, and devices shipping the Freescale i.MX 6 series. Primary development of this driver is being done by Wladimir J. van der Laan and he's using an Android tablet with a Rockchip RK2918 bearing a GC800 GPU.
