Wysocki" Hi all, The ata port runtime PM support patches have been merged. Now I move on to ahci controller runtime PM support. My test enviroment is: 1. use nfsroot, so disk is not mounted. AHCI controller can be runtime suspended. 2. use eSATA to test if hot plug works with port/controller runtime suspended. I send these RFC patches to get feedbacks. Any comment is much appriciated.
