Hi, I am developing a device driver for a PCI card. I require to map physical address of the buffer to it corresponding virtual address ( something that is inverse of vtophys ). Can anyone tell me how to do it. As I am operating with multiple channels it may not be possible for me to keep a translation of the virtual to physical mapping after I allocate the buffer and do a vtophys operation. I will be glad if anyone can send me a lead on this to vijay@utstar.com Thank you, vijay.
