There is no reliable list of supported cards, because things changes too fast and the marketing stuff that put random names on boxes make the maintaince of such a list an almost impossible task. > Are there a list of graphic-chips where i could see which chipsets support > the DRI/DRM-feature under OpenBSD? DRI/DRM on OpenBSD works on recent intel chips (i855 and up) and on older ATI chips (r200/r300). > Did the support depends in the xorg-driver or at the OpenBSD kernel > implementation of DRI? It depends on 3 things: - support of it in Mesa - support for it in the xorg driver - support of it in the drm module in the kernel. For the first 2 points it's relatively OS neutral (there aren't too many OS dependant stuff there and its relatively easy to track upstreams releases). For the in-kernel driver there is a lot more work involved. Thanks to Owain OpenBSD has done a lot of progress in this area, but there are still chipsets that are not supported here because the kernel driver almost need a full rewrite to be adapted from Linux to the OpenBSD kernel. And also in Xorg and Mesa the only active developpement that is done is on Intel and ATI chips,. Other chips (VIA, and nVidia --nouveau--) are beeing worked on too, but a much slower rate mainly because of the lack of documentation. -- Matthieu Herrb
