Power Management and Delivery
The 82583V supports the Advanced Configuration and Power Interface (ACPI 2.0)
specification as well as Advanced Power Management (APM). This section describes
how power management is implemented in the 82583V.
Implementation requirements were obtained from the following documents:
• PCI Bus Power Management Interface Specification .................................Rev 1.1
• PCI Express Base Specification .............................................................Rev.1.1
• ACPI Specification ...............................................................................Rev 2.0
• PCI Express Card Electromechanical Specification ....................................Rev 1.1
Assumptions
The following assumptions apply to the implementation of power management for the
82583V.
• The software device driver sets up the filters prior to the system transition of the
82583V to a D3 state.
• Prior to transition from D0 to the D3 state, the operating system ensures that the
software device driver has been disabled. See Section 8.4.4.2.3 for the 82583V
behavior on D3 entry.
• No wake up capability, except APM wake up if enabled in the NVM, is required after
the system puts the 82583V in D3 state and then returns the 82583V to D0.
• If the APMPME bit in the Wake Up Control (WUC) register is 1b, it is permissible to
assert PE_WAKE_N even when PME_En is 0b.
Power Consumption
Table 16 and Table 17 list power consumption in various modes (see Section 3.5). The
following sections describe the requirements in specific power states.
