Is the suspend be the job of OS instead of firmware?
That's an interesting question. Proprietary BIOSes used to do suspend to disk
- I had a laptop 7 years ago that did it (HP Omnibook XE2). Every laptop I've
owned since then does not have a suspend feature.
Would having the BIOS do suspend require a BIOS callback? What was described in this thread made it sound like a callback is necessary.
Suspend to RAM currently appears to be something that the OS cannot do alone. At least because cpu wakeup has to go through the BIOS.
Beyond that I think you are likely to get a lot more users and a lot more debugging and testing if you put the work in the OS.
