Hi All, In PPC Linux, to bring a particular IO page onto Linux addressing space, we use ioremap64(). Is my understanding correct? If I want to map this remapped address on user space, I have to use remap_page_range() of kernel in my driver. remap_page_range() takes a 32-bit physical address as argument. But in 440GP, all addresses are 36-bit with respect to processor. Is there any 64-bit equivalent of remap_page_range(). If it exists, how to use it?
Please help me out since I am stuck while mapping an external peripheral registers onto user space. Thanks in advance. Regards, vishwa ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
