What do you mean about physical address and what do you need it for ? Again on the bus itself, it's at 0 (overlapping RAM for AGP cycles only though) which is what you put in AGP_BASE_ADDR, but the engine "sees" it at MC_FB_LOCATION which is usually set right above the framebuffer. > > > 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? > > > No and this why this work :) It use the linear AGP. Can you explain more ? You can't just map the linear AGP from it's physical address on uninorth.
