ARM suspend to disk?
Quoted 6 lines · Kevin Hilman
What do you expect to gain from suspend-to-disk + snapshot boot that you don't already get from suspend-to-RAM using off-mode?
On OMAP, with off-mode enabled, a suspend to RAM puts the entire OMAP into full-chip off, and essentially reboots the ARM when waking up from suspend (or idle) already.
A long dead thread, but what you can do with suspend to disk, is suspend to disk, swap batteries to a spare, and resume where you were. I'm specifically thinking about my Nokia N900 cell phone.
Other reasons I would have liked it,
- When the battery level gets critical, suspend to disk rather than killing it when the battery drains, when I'm not at a place to charge.
- Swapping SIM cards (it's under the battery).
- Airlines, "yes we really mean OFF not (fill in the blank)"
