└─>Intel MIC Host Driver
In linux kernel since version 3.10 (release Date: 2013-06-30)  
This enables Host Driver support for the Intel Many Integrated
Core (MIC) family of PCIe form factor coprocessor devices that
run a 64 bit Linux OS. The driver manages card OS state and
enables communication between host and card. Intel MIC X100
devices are currently supported.

If you are building a host kernel with an Intel MIC device then
say M (recommended) or Y, else say N. If unsure say N.

More information about the Intel MIC family as well as the Linux
OS and tools for MIC to use with this driver are available from
