Hello, I'm looking to get a X600 PCI-E card, which seems to be based on RV380 chipset, which is supposedly almost identical to other R3xx series, but use PCI-e instead. Do you have any idea whether DRI/DRM works on these? I've got a X1550 installed in one of my machines. Works, but I have to disable the IRQ assignment to the card. If I do not do this it will interfere with the NIC using the same IRQ. OpenGL is only version 1.3, I don't know if there is a difference in the X600 driver. Kind regards Markus

DRI/DRM on OpenBSD works on recent intel chips (i855 and up) and on older ATI chips (r200/r300). I don't know if the above was a typo or not, but I do *seem* to have DRI and DRM functioning properly with the i845 chipset. None the less, I'm uncertain if there is actually support for i845 in our DRM driver? I'm still tinkering and testing the new intel(4) driver with the i845 system but it seems I've isolated the major problem that makes X unusable on the i845. The short answer is the driver does Bad Things when you allow it to do DDC2. It works fine with DDC1 enabled. Shutting off DDC2 support solves just about all the problems. Option DDC2 false I do not understand why this works, by my current hunch is it has to do with the rescaling the new intel(4) driver does when faced with fixed resolution LCD's (discovered via DDC2). -- J.C.

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.

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
