Summary

Glamo3362 is the graphics chip in the Neo FreeRunner. It supports 2D and 3D acceleration, and provides an extra SD interface which is used for the uSD card slot (the other one is used for the Wlan adaptor).

Glamo's 2D engine is currently used to accelerate solid fills and blits in both XGlamo (Kdrive) and X.org (xf86-video-glamo).

The datasheets for the chip are not public, but have been made available (under NDA) to a few community volunteers who are interested in working on accelerated drivers. Please post to the devel mailing list if you are interested in joining in this effort. This mailing list thread has some discussion on the topic.
