Let me explain the challenge I am facing. A prototype powerpc platform that I work with has the capability to transition memory banks to content-preserving low-power states at a per-socket granularity. What that means is that we can get memory power savings*without* needing to go to full-system-idle, unlike Intel platforms such as Sandybridge.
btw this is not a correct statement even Sandybridge can put memory in low power states (just not self refresh) even if the system is not idle (depending on bios settings to enable this) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
