Be prepared to be flamed for that on lkml, using /proc for stuff like that (i.e. driver specifix settings) is depricated these days. It should go to sysfs instead. I can come up with a patch for that, might take some days though as I'm busy with some non-xen stuff at the moment. cheers, Gerd btw: can whoever runs the changelog list (rik?) please add the repository (2.0, unstable, ...) to to subject line please? And while you are at it: -p1 for the diffstat would be cool as well, especially for one-file commits, there are -- for example -- plenty of page.h files in the tree.

This should happen when xenbus is implemented -- it can create a virtual bus in sysfs and then virtual device info and parameters can hang off of that. I think someone from Redhat (possibly Jeremy Katz) was going to look into implementing xenbus. For the time being I don't see any reason for them not to hang out in /proc. We probably want xenbus before going into mainline anyway. -- Keir ^ permalink raw reply [flat|nested] 2+ messages in thread
