What type of DMA page are you using ? The AGP ones ? The DRM in my kernels have hacks to make this work with Apple UniNorth chipset (though I never managed to have AGP operations stable with neither r128 or radeon, the card dies after a while). If it's normal PCI DMA, there should be no difference between x86 and PPC, at least on pmacs What PPC machine is this ? (sorry, I missed the beginning of the thread). On some PPC's like PReP, the mapping between bus addresses and CPU physical addresses on PCI isn't 1:1 and the system RAM is not mapped at 0 for bus mastering PCI devices. If you use the PCI DMA API, things are ok. If you aren't, then some tweaks may be needed. (See the definition of deprecated virt_to_bus in asm-ppc/io.h) Ben. _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
