Hey folks, I'm reading through Linux Device Drivers, 2nd ed., trying to get a feel for how linux driver development works. However, LDD is 2.6-unaware so I've hit a small stumbling block. I know it's possible, with udev/sysfs, to make a /dev node appear as one loads modules implementing the required functionality. My question is, does udev have to explicitly know (presumably in a configuration file) about _every_ kind of device it will encounter? That is, suppose I make a module for some device, do I have to also tell udev somewhere in userspace that that module maps to a specific /dev node? Or can udev extract this information from something in the module itself? If the latter is the case, how do I do it? Thanks, Athul -- Kernelnewbies: Help each other learn about the Linux kernel.
