Q: What is the meaning of the VPD keyword "New Capabilities" (CP)?




Hello,

our adapter supports the "New Capabilities" VPD and Power Management.
The PCI VPD ECR (from October 16, 1997) defines a new VPD keyword
"Extended Capability" (CP) which identifies the capabilities Control/Status
register in the device's address space.

The Power Management Control/Status register of our adapter can be read
(but not be written) in the device's address space.

Q: It is mandatory to define the CP keyword if any "New Capabilities"
   are supported?

Q: Why should 'someone' access the capabilities control/status register
   in the device address space although it can be read/written in config space?

----

Q: Are there any new VPD keywords defined until today?

TIA
