Description
31:27 RO
19h
PME Support:
This field indicates the power states in which this device may
indicate PME wake via PCI Express messaging. D0, D3hot, and D3cold. This
device is not required to do anything to support D3hot and D3cold; it simply must
report that those states are supported. Refer to the PCI Power Management 1.1
specification for encoding explanation and other power management details.
26 RO
0b
D2:
Hardwired to 0 to indicate that the D2 power management state is NOT
supported.
25 RO
0b
D1:
Hardwired to 0 to indicate that the D1 power management state is NOT
supported.
24:22 RO
000b
Auxiliary Current:
Hardwired to 0 to indicate that there are no 3.3Vaux auxiliary
current requirements.
21 RO
0 b
Device Specific Initialization (DSI):
Hardwired to 0 to indicate that special
initialization of this device is NOT required before generic class device driver is to
use it.
20 RO
0b
Auxiliary Power Source (APS):
Hardwired to 0.
19 RO
0b
PME Clock:
Hardwired to 0 to indicate this device does NOT support PME#
generation.
18:16 RO
010b
PCI PM CAP Version:
Hardwired to 02h to indicate there are 4 bytes of power
management registers implemented and that this device complies with revision
1.1 of the
PCI Power Management Interface Specification
.
15:8 RO
90h
or
A0h
Pointer to Next Capability:
This field contains a pointer to the next item in the
capabilities list. If MSICH (CAPL[0] @ 7Fh) is 0, then the next item in the
capabilities list is the Message Signaled Interrupts (MSI) capability at 90h. If
MSICH (CAPL[0] @ 7Fh) is 1, then the next item in the capabilities list is the PCI
Express* capability at A0h.
7:0 RO
01h
Capability ID:
Value of 01h identifies this linked list item (capability structure) as
being for PCI Power Management registers.
