Summary: AGP KMS x11 video perf problem. Product: DRI Version: XOrg CVS Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.sourceforge.net ReportedBy: li...@andyfurniss.entadsl.com RV670 AGP running git ddx, xserver, libdrm and drt + nopat/AGP ttm caching fix patch. Problem is not new. I think there is a caching problem with KMS that does not happen with UMS which makes video that doesn't use xv like flash or mplayer -vo x11 eat too much Cpu. A partial work around can be achieved by disabling accel UTS, but it's still not as good as UMS. Some top figures - this is with mplayer -vo x11 704x...@25fps Cpu is single core 2.1GHz.
