Hi Lorenzo,
I think, you are referring to statement,
"The Completion ID field is not meaningful prior to the software
initialization and configuration of the completing device (using at
least one Configuration Write Request), and for this case the
Requester must ignore the value returned in

Hi Lorenzo,
Yes that's true..
My question is: what if EP function default completer ID means BDF has
values = 0(meaning B = 0, D = 0, f = 0) and Root complex requester ID
also has same BDF, that is 0.
Is that valid case as per PCIe standard, as in this case, requester ID
and completion ID
Hi Lorenzo,
Yes that's true..
My question is: what if EP function default completer ID means BDF has
values = 0(meaning B = 0, D = 0, f = 0) and Root complex requester ID
also has same BDF, that is 0.
Is that valid case as per PCIe standard, as in this case, requester ID
and completion ID

Hi Lorenzo,
Thank you very much for reply.
As you mentioned I noted that, "If a Function must generate a Completion
prior to the initial device Configuration Write Request, 0’s must be
entered into the Bus Number and Device Number fields"
By above statement this means that completion ID

Hi All,
I was referring Linux code for PCIe enumeration and I have one doubt
w.r.t to very first operation that must be done on device.
Currently while scanning for device, we directly read vendor ID from
device. But PCIE base specification
Hi All,
I was referring Linux code for PCIe enumeration and I have one doubt
w.r.t to very first operation that must be done on device.
Currently while scanning for device, we directly read vendor ID from
device. But PCIE base specification
