I think I have too little context here, but FWIW: RADEON_MC_AGP_LOCATION is the location of the linear AGP aperture as seen by the chip. 0x0 is probably due to at least UniNorth bridges not providing a physically linear view of the aperture to the CPU. > Now i also get texture looking good with r300_demo, i will > look at r300_driver see where is the prob. Maybe r300_demo doesn't use hostdata blits for uploading the texture data? -- Earthling Michel DÃnzer | Debian (powerpc), X and DRI developer Libre software enthusiast | http://svcs.affero.net/rm.php?r=daenzer ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
