That was my conclusion as well. It appears that Arjan's patch does just that for the i830. I looked at the DRM code for the i810 and i830 a little bit. There is more overlap between those chips than there is between the R100 & R200! Somebody ought to take a stab at factoring out the common code / data structures into shared source files. It's too bad that we can't make a single i8xx.o DRM module that's used by both the i810 and i830 drivers. :( -- Smile! http://antwrp.gsfc.nasa.gov/apod/ap990315.html ------------------------------------------------------- This sf.net email is sponsored by: With Great Power, Comes Great Responsibility Learn to use your power at OSDN's High Performance Computing Channel http://hpc.devchannel.org/ _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
