Also, I'd like to investigate whether ARM will require a set of platform_hibernation_ops - Samsung's patch from last December,
http://www.spinics.net/lists/arm-kernel/msg108565.html
Hi FrankH,
The patch seems has connection with this
www.kernel.org/doc/ols/2010/ols2010-pages-9-18.pdf
You can see the section 4.3 fast device reactivation.
It does the similar thing as STR, but drivers status are kept in hibernation image instead of main memory.
I guess this is why this patch comes out.
In the current device driver model, there are no appropriate handling specific to
hibernation_suspend/hibernation_resume ops.
So they make their own interface/platform drivers.
seems to indicate that they believe it's necessary at least on some ARM hardware. OMAP has similar functions to that, it'd be great to unify.
FrankH.
