> I works about the same way with the 2.6.9-rc3 kernel I'm running. Ditto here, but with gentoo-sources (2.6.10), and the official nvidia drivers. In fact I get a much bigger performance hit with yes+glxgears (glxgears drops to 2fps)... But yes, the point is that something is going mad here... not good :/
I'm still trying to conceptialise the mechanism. Am I right in thinking that the kernel driver will initiate DMA between the card and user process for transporting command data, because pulling the memory using normal methods will be painfull? I suppose one advantage of this method would be that a process wouldn't need any special privelages because it isn't initating the DMA transfers. In fact, this whole idea sounds like SGI's graphics pipe (which I like) :) -Lucas _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
