All, Is there an easy way to determine how Linux has remapped a 32 bit physical PCI address on a 64 bit machine(40 bit phys)? Backgrd: Driver running on IA64 machine with PCI H/W that has some 32 bit addressing. IA64 uses I/OTLB to remap 32 to 44 bit address. Driver ported to AMD64 (Debian etch running x86_64). Driver installs and runs. I just need to verify the Machine I am on is really doing address translation in H/W and is not using bounce buffers, which would involve an extra copy. BTW - I use pci_map_single and unmap single to set up the dma. Timothy.ruggles@xxxxxx -- Kernelnewbies: Help each other learn about the Linux kernel.
