PCIe: Which devices supports more then one Virtual Channel (VC)?

Currently Intel FPGAs only support one VC. None of the device offers the optional 7 VCs. Regards, Nathan

Hie, My apologies for the delayed response, as I missed your last questions. Please check my replies: Question: What I don't get is, why then, in all the documentations for the Avalon Interface the 7 VCs are mentioned? Answer: The 7 VCs are only mentioned in the Address Map of Hard IP Configuration Space Registers. The address mapping of config space registers allocated memory space for optional features as well in the event the features are to be added in later revisions. Question: They always describe the "Address Map of Hard IP Configuration Space Registers", where VC0-VC7 is mentioned. Is there any way to access to this configuration space registers? Answer: As mentioned above, only the memory space is allocated. However, currently accessing the configuration space will not enable the VC feature as the equivalent arbitration logic is not available in the Hard IP. Question: Which Intel FPGAs/SoCs supports more than one TC (Traffic Class)? Answer: For now Arria V, Arria 10, Cyclone V, Cyclone 10, Stratix V and Stratix 10 devices support more than one TC.
