Hi,
[For review during our WIMS WG session next week at PWG F2F]
Based on review during WIMS teleconferences and email, an updated
PWG Power Management Model is posted at:
ftp://ftp.pwg.org/pub/pwg/wims/wd/wd-wimspower10-20091007.pdf / doc
- Clean version with line numbers
ftp://ftp.pwg.org/pub/pwg/wims/wd/wd-wimspower10-20091007-rev.pdf / doc
- Redlined version with line numbers
This version defines all intended content - minor issues of
conformance requirements remain - also, more use cases
would be desirable.
Cheers,
- Ira
