Hi Mike,
Actually, the EMAN Monitoring MIB now has a table
(similar to ours) that defines the max power (but not
other characteristics) of each state - so PWG vendor
states could be listed.
But it's tail wagging dog for MFDs to force new logic
in power management apps for the whole computer
industry. That's why I think that we should not allow
the reporting of vendor extension states in EMAN.
In DMTF CIM there is NOT a way to insert these
vendor extension states (or their characteristics), so
the EMAN mapping would be of limited utility.
Cheers,
- Ira
