Deep Sleep, aka Hibernate finaly comes to osx86

Yeah, it works, my hackbook pro jsut woke up from deep sleep, with pcefi v9 beta.

thx to Turbo for support.

pcefi v9 comes some time later, with x86_64 kernels support and deep sleep support.

althought, some mobo fails to make sleepimage and goes to s3 sleep instead of deep sleep, like gigabyte, asus.

i hope it can be fixed.

here is log from dmesg

gigabyte ga-ep35-ds3p just woke up from sleep, with less then 4gb ram, 4gb causes some fails(32-bit integer overflow), working on fixing it.

    Good job netkas!
    you don’t need me to restate how important you are to the osx86 community
    This release really helps PC EFI against Chameleon…

    W00t, very good work, Netkas ๐Ÿ™‚


    ‘against Chameleon’?

    In case you didn’t notice: We’re all in the same gang, it doesn’t matter who is first and it is important to have more than one project.

    Are you EVER going to allow passing in the boot device so we don’t have to hit keys and type in a non-sensical number on EVERY DAMN BOOT?

    You know, what people have been asking about for over a year?

    Hmm…X86_64 support? That should mean that given a Snow Leopard kernel…we’ll be able to use the 64-bit mode…
    Question: For your Snow Leopard setups, have you had to strip off the 32-bit kernel binary from the Universal to force it to boot 64-bit?
    nice work!

    I just want to know,where can i get the pcefi v9.

    When will we put hands on a 64 bit kernel? Iยดm anxious for it.

    4gb problem on YOUR (ep35-dsr3p) machine might be related to Jmicron IDE controller? Not the (e)sata ports with AHCI, but the IDE ports of the jmicron controller… it’s only the IDE ports that needs a patched jmicron.kext to let IDE work with LESS than 2/3gb of memory, WHEN 4gb random kernel panics

    Otherwise it might be the 889a audio codec.

    But maybe you tried waking from sleep without these devices enabled in bios…

    I’d take it as a great new, if I only had the classic sleep working, before thinking about the deep one.

    Can it be that a GUID partition table (GPT) formatted disk is required for this to work? Or does anyone have this working on a traditional MBR-style disk?
