This current implementation and usage model isn't what we need moving
forward.  If we decide in the future that autoshutdown is valid and
desirable we can design a better implementation and a better user interface
then.  The Energy Star for Server V2 will probably dictate a lot of the
features for the servers that need to be implemented in the future.

This fast track is to deprecate Auto-Shutdown for Solaris.next. Or are you talking about
deprecating MOU??   There are no plans nor demand for  implementing MOU5
on Sparc workstations (there are no non-EOL'ed ones) or X86 workstations. We went down that route last year for possibly implementing MOU5 on x86; no demand for it.

Thanks

  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!

Hi All,

This is a draft fast track proposal.

Please comment if you see any issues or need clarifications
on anything.

1.0 Introduction

1.1 Project/Component Working Name:

   Auto-Shutdown power management property deprecation

1.2 Purpose

    This project seeks to deprecate two Sparc workstation only property from
power.conf as we move from power.conf to SMF.

2.0 Description

We are in process of moving properties from power.conf to SMF.  As we do so,
we would like to remove properties that are not longer needed or that the
hardware no longer supports.

One such property is autoshutdown and the related property idleness.

Looking at previous ARC cases, there have been quite a few ARC
cases where power management driver ioctls and power.conf properties
have been removed.


3.0 Delivery

Announcement of the deprecation would be in a Solaris 10 update
release with the actual removal of the two properties in Solaris.next.

Deprecation announcement would entail updating the man page for
power.conf and inserting a comment in power.conf stating this
property will be removed in a future Solaris release.

Deprecation of the property would be in a patch release with removal
of the feature in a minor release.

4.0 Technical Description

The two properties in question are Auto-Shutdown and idleness. These
are currently edited by the user in power.conf and then written to the kernel
by executing pmconfig.

# Auto-Shutdown     Idle(min)    Start/Finish(hh:mm)    Behavior
autoshutdown        30          9:00 9:00              noshutdown
                                                       shutdown
                                                      autowakeup
                                                      default
                                                      unconfigured

idleness    ttychars
                 loadaverage
                 diskreads
                 nfsreqs
                  idlecheck  (name of a program of run)

There is also a PM_IDLETIME environment variable that would no longer be
needed.

The idleness property is related to the autoshutdown property to determine
idleness of system and triggers shutdown behavior.

This Auto-Shutdown/idleness feature was implemented only on SPARC
workstations for MOU3 compliance and was never implemented on any x86
boxes.  Furthermore, there doesn't seem to be any plans for further SPARC
workstations or the implementation of the latest MOU5 compliance spec
on any Sun workstation.  Additionally, this feature is not supported on any
SPARC Sun4v servers.

It looks like all Sparc workstations have EOL'ed.  According to
PSARC/2009/572, all of them have been EOF'ed in OpenSolaris
except for SunUltra25 and SunUltra45.  These boxes were FCS'ed
in early 2006.


4.2 Interface Classification

    The project exports the following interfaces:

   Auto-Shutdown           power.conf property        idleness
power.conf property
PM_IDLETIME             environment variable

Current classification of these properties is Evolving, according to the
power.conf man page.  Still looking for the ARC case that exported them.
