Re: old Mach32 and Mach64 servers
some mach64 mobility chips had a second crtc that was never supported. same thing with rage 128. I'm not sure about the accel engine on mach32, but I think mach64 is fairly well accelerated. If you want the databooks, register as a developer with ATI and request them (be patient). Also the old xfree86 3.x servers are a good reference for old cards.

One DRI developer makes a Xv/DRI merged driver available as well on his website (can't remember where off of the top of my head). This is the driver I use for my Mach64 and I think also the driver with the best support for the Mach64 chipsets. It would be very nice to see the Xv+DRI merged drivers made available for X. If only some important soul within the XFree86 project with the correct privileges has time to oversee the mergin off code into the XFree86 main branch how nice that would be!

I don't have access to the docs, but there are many chipsets with the mach64 core, going from (iirc) isa to agp (or at least gart). Also iirc it is used on laptop chipsets released after the radeon (ATI Mobility M1 springs to mind, but I can't easily confirm). Since these are based on the Mach64 they all use the mach64 driver although there possess very different features.

Same thing with most of the Savage chips, because I couldn't see an easy way to support it. Is this double-headed feature now common enough that there should be some kind of architectural support for it? I'm not sure what that support would look like, but implementing it today seems an awful lot like a hack. -- - Tim Roberts, [EMAIL PROTECTED] Providenza Boekelheide, Inc. ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
