The question(s) I don't see answered or addressed:
Is autoshutdown a desired feature for x86 desktops/laptops?
Is autoshutdown a desired feature for sparc/x86 servers?
Or possibly addressed in a different way:
Why is it not a bug that autoshutdown doesn't work on x86?
As specified in the case, autoshutdown is part of the MOU
requirements (including the current MOU5), removing this property
removes the ability of Solaris to configure this feature. And if the
feature is not desired in Solaris, the case should go the distance and
deprecate the feature.
Also, have we also verified that PM_IDLETIME isn't needed anymore?
Currently, the *only* algorithm used by Solaris to transition to lower
power states (including suspend via autoS3) is via idleness. So will
PM_IDLETIME also be needed for auto-suspend?
Cheers!
