This would be ideal (and it's broadly what the OLPC guys are aiming for, I think), but on most platforms you're looking at at least a second or so to resume. As far as I know, we're still looking at ~60 ticks a second at best for an average desktop, so that's not going to be a win. -- Matthew Garrett | mjg59@...f.ucam.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
