Dear David, the situation is still like it was some time ago: 1) VIA's 3D Xorg driver cannot be released as FOSS since it cotains 3rd party licensed code 2) VIA is very supportive of anybody in the community who will work on a FOSS 3D driver for Chrome9. However, we are not aware of any such project :( 3) VIA has released all the programming documentation that it has for this specific chipset, it is available from http://www.x.org/docs/via/ What is still missing is the pixel shader documentation, which will join those public documents soon. 4) VIA does not have the resources to write an entirely new 3D driver for Chrome9, especially since future products contain a different, incompatible GPU. I think it's much more useful to focus the resources at getting things "right" for those future products. So, as you can see, the situation is far from being perfect. However, it could also be much worse. I would be the first person to argue in favour of having some FOSS userspace code against this DRM kernel driver - but I can also understand the practical constraints. Given that the technical issues (32bit ioctl compat, ...) can be adressed, I would hope the driver can get merged. So far I was not aware that there is an absolute precondition of existing 3D FOSS userspace code to get a DRM driver merged. Yes, we all want it. But is it a strong requirement?
