Subject: [Tech Support] question about ARI Device definition<= span lang=3D"en-us">

hello there,

  &nbs= p;  thanks for quick response to my last mail. I have a new question h= ere.

  &nbs= p;  the definition of ARI Device in spec: A Device associated with an = Upstream Port.

If I understand = right, ARI device has an upstream port on the device, while non-ARI device = don`t have.

<= font color=3D"#0070C0" face=3D"Calibri">***********************<= /span>2242<= b> RESPONSE:  An ARI Endpoint and a = non-ARI Endpoint both have an Upstream Port.

But in figure 6-= 13 of PCIe spec 3.1, on ARI device X & Y, don`t see any notation of ups= tream port on it, should they have a notation of upstream port?

<= font color=3D"#0070C0" face=3D"Calibri">***********************<= /span>613 RESPONSE:  it should be obvious that a device connected to a Root Port or switch= Downstream Port must be a device with an Upstream Port.

and also, If I u= nderstand right, ARI device has a upstream port associated, so the main fun= ctionality of upstream port is routing msg to the functions immediately bel= ow the port?

<= font color=3D"#0070C0" face=3D"Calibri">***********************<= /span>2242<= b> RESPONSE:  The main feature of an ARI device is a Function Number field of 8 bits.

If you have any a= dditional questions, please let us know.
