Hi,

Can anyone who linux pcie driver knowledge can explain how to initiate vendor defined messages from root complex to the endpoint.

And how to receive vendor defined messages in the driver if root complex receives a vdm.

    Hi Chaitanya,

    Is this related to a specific TI product?  If so, would you mind giving more information about which one you are using?

    If this is a general question, then this forum may not be the best place for this issue.  Much of the expertise on this forum applies to TI products and not full systems.

    That being said, would it be possible for you to use Python and the pynvme library in order to send the vender-defined messages from root complex to endpoint?
