Adding arch support for hibernation to arm64 should be fairly simple, it is not top priority at the moment simply because there are not compelling use-cases (on the PM side most features revolve around CPUidle and suspend-to-idle and S2R). To answer your question, yes I have planned to support it, I just do not want to add it to the kernel for no particular reason, if there are compelling requirements (I guess you are asking for a specific reason) it can be done fairly quickly. Thanks, Lorenzo ^ permalink raw reply [flat|nested] 4+ messages in thread

Thanks for the information. Could you please CCed me the hiberation patches when you send them to list. I can help test it. :-) Cheers, Baozi. ^ permalink raw reply [flat|nested] 4+ messages in thread

Perone @ 2015-05-27 18:51 UTC (permalink / raw) To: linux-arm-kernel Thanks for the reply Lorenzo and Chen. I asked because it seems that someone tried before and failed [1] due to some page faults while calling copy_page(). I'm also interested in testing the patches.
