Created an attachment (id=1182)
--> (http://defect.opensolaris.org/bz/attachment.cgi?id=1182)
choose next idle type according to the cpu utilization
This is the new one against 8099.
With c-state enabled, while p-state is disabled from BIOS,
on pad-gate head, I got:
===========================
Target Load | Actual Load | ssj_ops | Average Power |
| | | (W) |
------------- | ------------- | ------------- | ------------- | -------------
100% | 98.9% | 93,437 | 205 | 456
90% | 89.9% | 84,853 | 192 | 443
80% | 79.8% | 75,352 | 183 | 412

20% | 19.8% | 18,708 | 151 | 124
10% | 10.3% | 9,687 | 147 | 66.0
Active Idle | 0 | 140 | 0
sum of ssj_ops / sum of power = | 280
=========================
And with this patch, SPECpower result shows:
=========================
