Intel scalable Switch IP

[Priyanshi]

Is there any means by which I can get the default values of the capability registers implemented in the configuration space of intel's gen 5 scalable switch IP ???

[Priyanshi]

The PCI-SIG's base spec lists the default values of each capability register. I am planning to refer that only. But is there any other resource specific to intel's switch IP for the same ?  It would help better.

Hi Priyanshi,

Thanks for reaching out.

I would recommend you refer to the Scalable Switch Intel® FPGA IP for PCI Express* User Guide for the methods to read the configuration space registers. Here are some useful sections from the user guide:

1.Scalable Switch IP Debug Toolkit:

You can use the Debug Toolkit to read configuration space registers, such as the PCI Express Capability Structure. For instructions on enabling and launching the Debug Toolkit, see Section 4.8.3 Debug Toolkit, in the user guide.

2.Register Access Interface (RAI):

The RAI allows you to read registers of the Scalable Switch IP in Upstream Port Type and Tile, including configuration space registers. Refer to Section 5.6, "Register Access Interface," for details on how to use the RAI, and Section 7 for a list of accessible registers.
