Hi, I want to do the following from a kernel module or kernel code : Read a byte from any page in physical memory. It doesn't matter if that page is being used by a process or not. >From an earlier post someone recommended I use ioremap() to map the pages (build page tables) into the kernel and then read a byte from the page. I wanted to know if its ok for the kernel to map to a page that is being used by a process ? Also is this page any different after the mapping , i.e. does it have any different characteristics when compared to a process' page that has not been mapped by the kernel ? thanks Arjun -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
