Since the "new" DRM has been integrated in current by the end of April, I've been unable to use DRI with my ATI card. The X server starts and apparently works, then suddenly (when scrolling an xterm or doing some memory-intensive operation like 3D rendering) enters a busy loop. After an awful lot of searching and attempting to debug the code, I've finally been able to find out that the server loops on an ioctl(DRM_IOCTL_DMA) returning EBUSY, which means that the DRM driver can't get a free buffer from radeon_cp.c:radeon_freelist_get(). My XFree server is the latest version of the package (XFree86-Server-4.3.0_8). Earlier versions exhibited the same behaviour. Does anyone have a clue on where to investigate some more and fix that? -- Pierre Beyssac pb@fasterix.frmug.org pb@fasterix.freenix.org Free domains: http://www.eu.org/ or mail dns-manager@EU.org
