Power mangement system of FreeBSD needs additional abstract layers to hide underlying PM system like many device driver does for network, storage, etc. >> Specifically, we'd like to support ACPI in a sane manner, which >> includes its power management facilities. Does "support ACPI" means "using ACPI as the abstract layer", or "using ACPI as underlying PM system?" Perhaps this question is pointless because I'm not familiar with ACPI spec, but as far as I remember, ACPI spec is reated not only with power mangement hardware/BIOS, but also with OS support for these features. -- HOSOKAWA, Tatsumi Assistant Manager Information Technology Center, Keio University To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
