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?
