    If AMD EPYC support PCIe AtomicOps host-to-device transactions?

    kangm

      PCIe spec defined 3 types of AtomicOps transactions:

      "AtomicOps are architected for device-to-host, device-to-device, and host-to-device transactions."

       

      If AMD EPYC support PCIe AtomicOps host-to-device transactions using ISA instructions? or only support device-to-host, device-to-device transactions?
