guys, i think you are talking about different things here:
1) suspend-to-disk by bios functions:
- needs own partition or contiguous file in (fat) partition
- suspend is serviced by the bios (?)
- wakeup is directly supported by the bios
2) hibernate support in w2k
- does not need anything except w2k installed on a sane partition
- works only in w2k
- suspend is done via mem/reg dump in the w2k kernel to a specific
file on the w2k boot partition
- wakeup is supported by w2k's bootloader which does not use bios
calls or whatever, but reads the mem image, sets up all the
protected mode structures and just starts execution where it
trapstopped where it was told to hibernate
- this is rather a debugger feature ;-)
some generic ideas on portable hibernate support:
- one could use the swap partition (it is used for crashdumps anyway, if
you enabled them)
- this could be implemented in ddb, since it already writes core files
to the swap partition
- resume support has to be built into the bootloader which has to load
the ram core from the swap partition, set up all structures and start
it
peter p: this could be somewhate related with your ideas on what-to-do
with corefiles, too -- thus a cc: to you ;-)
ideas? comments?
