Hello, I'm trying to see how I could implement Suspend To Ram on my system that embed a SH4 processor. I'm almost completely new to this area so please forgive me if the question is dumb. I read the documentation in Documentation/power and must admit that I don't get all of it :) So my question is that when we suspend the system, it seems that all IRQs are masked and I'm a bit suprise since the event that should wake up the system is an interrupt. This mask is done by arch_suspend_disable_irqs() and none of the arch is overriding this stub. If I'm right, how the system should be waked up ? Anther point is that the device that consumes a lot on the system is the hard drive. I can decrease its power consumption by stopping its motor by using "hdparm" but it still consumes too much. So for now I'm thinking of stopping to power it up completely. But I don't know it's going to be easy to resume the hard drive. Does anybody have another idea or have already experience such trick ?
