Contact:	Sudeep Dutt <sudeep.dutt@intel.com>

Description:

		The mic class directory belongs to Intel MIC devices and

		provides information per MIC device. An Intel MIC device is a

		PCIe form factor add-in Coprocessor card based on the Intel Many

		Integrated Core (MIC) architecture that runs a Linux OS.



What:		/sys/class/mic/mic(x)

KernelVersion:	3.11

Contact:	Sudeep Dutt <sudeep.dutt@intel.com>

Description:

		The directories /sys/class/mic/mic0, /sys/class/mic/mic1 etc.,

		represent MIC devices (0,1,..etc). Each directory has

		information specific to that MIC device.



What:		/sys/class/mic/mic(x)/family

Date:		August 2013

KernelVersion:	3.11

Contact:	Sudeep Dutt <sudeep.dutt@intel.com>

Description:

		Provides information about the Coprocessor family for an Intel

		MIC device. For example - "x100"



What:		/sys/class/mic/mic(x)/stepping

Date:		August 2013

KernelVersion:	3.11

Contact:	Sudeep Dutt <sudeep.dutt@intel.com>

Description:

		Provides information about the silicon stepping for an Intel

		MIC device. For example - "A0" or "B0"

	default N

	help

	  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

	  <http://software.intel.com/en-us/mic-developer>.
