## Chipset Name

* CLE266 
* Castlerock 
* Unichrome 
* [[ProSavage|ProSavage]]-DDR400 

## Status

Alan Cox ported the 3D driver to a more recent version of mesa.  [[ErdiChen|ErdiChen]] put the 3D driver in Mesa cvs.  The cleaned up and improved 2D driver from XFree86 has not yet been integrated into DRI cvs. 


## Specifications

The basics can be deduced from the driver_lite source from VIA. Its a fairly generic "queue up the vertices and fire" type chipset and the most noticable thing about it appears to be the lack of hardware clipping. When its not doing fallbacks performance seems comparable to the onboard intel stuff but its not radeon grade.
