Now, if you have a VIA graphics chip, things may be better since they recently released an [http://linux.via.com.tw/ open source driver] for both 2D and 3D operations. |

There are virtually no tutorials or datasheets for the 2D acceleration features either, but at least we have open-source code for them. Among other sources, the Xfree drivers, [https://github.com/haiku/haiku/tree/master/src/add-ons/accelerants Haiku (was Open BeOS) accelerants] and [http://www.shawnhargreaves.com/freebe/ FreeBE/AF]. They may provide enough information to reverse-engineer and figure out a model that could be used to program/port for your environment. Some older cards with only 2D acceleration might be documented by the [ |
