I've reappeared - sort of. Current weather forecasts suggest that some skiing time before school restarts may be mandatory. If I understand this patch, it's a means for exporting the firmware's view of the hardware to user space. I can pretty well guarantee that any implementation based on /proc is not going to get into the mainline kernel. I, personally, would not even post it. Sysfs is more possible. Some thoughts on that: - Sysfs already implements a representation of the device tree. It's worth pondering whether that representation can be extended to contain the desired information. - There are some firm rules about sysfs files; among other things, each must contain exactly one value in a textual representation. So some of the /proc/device-tree files would have to be reworked to meet those expectations. An alternative which may be worth considering is simply creating a new virtual filesystem. We could create olpcfs, put anything we want into it, and there should be few complaints. It could be mounted on /olpc or wherever. And it would all be pretty easy to do. Just a thought. jon _______________________________________________ Devel mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/devel
