Allwinner A10 DRM Display Support Being Worked On
This Direct Rendering Manager driver is for the Allwinner A10 and subsequent SoCs. The driver is currently dubbed sun4i-drm. This driver is only about supporting the display block and nothing to do with 3D hardware accelerated graphics support.
The open-source 3D support for this hardware would have to come separately via the stalled Lima driver for supporting the Mali 400 as the GPU found on the Allwinner A1X series. The Allwinner A1X SoCs use single-core Cortex-A8 processors.
