I don't think it's stupid. I think that *ATM* it shouldn't be implemented for the reasons you explained. I agree that CONFIG_TIMER_STATS should never be in the official kernel, but I hope that CONFIG_USB_SUSPEND will someday, when software problems are fixed, make it. In particular, I'd like to comment on the two points I don't fully agree with: > - 1w is nothing. It's not worth saving given the above downsides, that > could even cost more battery Here, have fun: http://www.crhc.uiuc.edu/~mahesri/classes/project_report_cs497yyz.pdf :-) (first result for "laptop power consumption" in google). A brief summary: a modern laptop system consumes between 7.5 and 30 Watts (figure 3). One watt so is between 3.3 and 13.3% of the total power consumption. This means that for an office/desktop use you should gain *at least* 5% more battery life taking other precautions. If we take 3 hours of full battery life (it could be even more on recent systems), then we could extend it of 9 minutes. That, if not much, is still something in terms of office productivity. The minimum/maximum calculated on this back-of-an-envelope analysis is 6/24 minutes of work. Not bad, I think. > - You could save the aforementioned 1w, just by unloading your usb > driver. Far better solution than a kludgy config option. Yes. And you wouldn't charge your phone/ipod/whatever. I'd rather put that 1W in my ipod than wasting it. bardo _______________________________________________ arch mailing list [email protected] http://archlinux.org/mailman/listinfo/arch
