on XO-1 and XO-1.5, we were able to discover the model of the laptop from the information under /sys/class/dmi/id. the DMI schema comes from the PC world, and we can't expect it to exist on ARM.
there was also information to be found in /ofw on those machines, like serial number, and uuid. the hex model designator found there was used as a fallback if the dmi tree wasn't there (on older XO-1 firmware). on 1.75, there's no dmi tree, and /ofw has moved to /proc/device-tree, so we need to modify a lot of places that try and dig up platform info. (see #11116) so i'm floating the attached script, tentatively named olpc-hwinfo, as a strawman. i think it gives access to the most often needed info, and can obviously be expanded if needed. it would go in olpc-utils, which would put it in /usr/sbin (since some clients live in /usr/sbin). thoughts/comments? better approaches? obvious additions? paul =--------------------- paul fox, p...@laptop.org
