Yes, on Linux, you will see something like this in lstopo v1.7:

  HostBridge L#0
      PCI 8086:225c
        CoProc L#2 "mic0"

And these contain some attributes saying how many cores and how much
memory there is in the Phi.

lstopo from the host doesn't currently create cache/core/thread objects
inside the Phi but you can also run lstopo inside the Phi if needed.
