Drivers get sysfs attributes by using the driver core (registering a subsystem, defining attributes, etc.).However, if all you want to do is create and remove files under /sys (without using all the driver core), there is no simple way to do so (at least not that I could find). I am assuming that folks will want something that works like /proc does now.I wrote xen_sysfs.c to provide simple sysfs interfaces for non-drivers. It seems as though it would be a crime against nature to write a device driver just to create a file under /sys. Well, here's a question, and I really don't know the answer: It of course makes sense that the kernel maintainers want drivers to install themselves under /sys, and fit in with the whole kobject and hotplug infrastructure. But, for a few odds-and-ends special files that don't really relate to a device, is /proc also out of bounds these days? Seems to me that the kernel proc interfaces were designed to have a few random files thrown at them, in a way that the sysfs interfaces aren't. If the argument is really that random special files are a bad idea, that would continue to hold regardless of whether we move e.g., /proc/xen/privcmd to /sys. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
