Since the AtomBIOS branch appeared for the xf86-video-ati driver and the R500 support for DRM (the announcement
), we've been trying out this open-source software on a variety of different ATI Radeon graphics cards. As we reported a few hours ago, the xf86-video-ati driver is working with the high-end HD 2900XT 512MB
graphics card. We have now tried it out on multiple Radeon X1800 series graphics cards and it was running great there too. Using XAA acceleration was very smooth though with EXA we have ran into a few issues with the DRM R500 branch causing slowdowns. When trying out an ATI Radeon X800XL with the AtomBIOS branch (since the AtomBIOS support goes back to the R400 series) we have ran into TMDS issues. The exploration will continue and we'll report back soon with more findings and possible benchmarks.
