Pat, can we have a set of configuration options to disable a lot of the generic (!) code in kernel/power/*.c which isn't useful on embedded platforms? I'm looking at stuff like the swsusp infrastructure for clearing out memory, suspending to disk, the PM state management, etc? This type of stuff isn't at all useful on embedded platforms. On these platforms, you'd typically suspend all the devices except for a select few which would cause wake-up, put the RAM into self-refresh mode, and send the CPU to sleep and put the whole device into a low power "off" state. This requires none of the swsusp-like infrastructure, so I don't need most of the "generic" power code in kernel/power which I get for free just by enabling CONFIG_PM. -- Russell King (rmk@arm.linux.org.uk) The developer of ARM Linux http://www.arm.linux.org.uk/personal/aboutme.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
