The MIC COSM bus allows the co-processor state management (COSM) functionality to be shared between multiple generations of Intel MIC products. The COSM driver registers itself on the COSM bus. The base PCIe drivers implement the bus ops and register COSM devices on the bus, resulting in the COSM driver being probed with the COSM devices. COSM bus ops, e.g. start, stop, ready, reset, therefore abstract out common functionality from its specific implementation for individual generations of MIC products.

If you are building a host/card kernel with an Intel MIC device
|

then say M (recommended) or Y, else say N. If unsure say N.
