Core Reserved
Not Applicable or Implemented. Hard wired to 0.
0b Core PME Status (PMESTS)
Indicates that this device does not support PMEB generation from
D3cold.
00b Core Data Scale (DSCALE)
Indicates that this device does not support the power
management data register.
0h Core Data Select (DSEL)
Indicates that this device does not support the power
management data register.
0b Core PME Enable (PMEE)
Indicates that this device does not generate PMEB assertion from
any D-state.0:PMEB generation not possible from any D State
1 = PMEB generation enabled from any D State
The setting of this bit has no effect on hardware.See
PM_CAP[15:11]
Core Reserved
1b Core No Soft Reset (NSR)
When set to 1 this bit indicates that the device is transitioning
from D3hot to D0 because the power state commands do not
perform an internal reset. Config context is preserved. Upon
transition no additional operating sys intervention is required to
preserve configuration context beyond writing the power state
bits.
When clear the devices do not perform an internal reset upon
transitioning from D3hot to D0 via software control of the power
state bits.
Regardless of this bit, the devices that transition from a D3hot to
D0 by a system or bus segment reset will return to the device
state D0 un-initialized with only PME context preserved if PME is
supported and enabled.
