Just FYI: the tdfx texture memory management code is different because: 1. It was originally developed before the scheme Keith implemented for the i810 and mga drivers (and later used for the R128 and radeon). 2. There are some idiosynchracies with the Voodoo3 such as two separate banks of TRAM and needing to store alternate mipmap levels in alternate banks. 3. We did everything through the Glide interface, rather than working directly with the hardware. I don't know the history of the gamma's texture memory manager. -Brian _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
