However, I think my colleague Chris Ball will be there, so I have CC'd him. He has a long history of power management work at OLPC. Anyway, I think you have an understanding of the issues facing OLPC's power management model at the moment. We'd like to move to your wakeup events architecture and really nail our opportunistic suspend model, but upstreaming the support needed at the architectural level has been a challenge that I've been working on for over a year, and still isn't done. I think I see some influence of our remaining issues in the list of topics you wrote below, so that's great. > The topics I, personally, would like to discuss include: > - Per-device PM QoS > - Propagation of wakeup events to user space vs system suspend > - Possibility of representing dependencies between devices through > "device links" (i.e. objects representing master-slave links between > devices) > - Idea of common "platform" bus type that may cover ACPI devices (like > battery, fans etc.), PNP devices and current platform devices in a > consistent way > - Freezer improvements cheers, Daniel -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
