Hmm, the start/stop latencies are clearly properties of the hardware, but the save/restore latencies seem to be a function of the driver. e.g., some drivers may keep a shadow copy of their registers in memory so the save time is minimized. I don't have too strong of an opinion on this, but probably the drivers should just add their own values to the start/stop latencies to add the linux specific overhead.
