+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)/state
+Date: October 2013
+KernelVersion: 3.13
+Contact: Sudeep Dutt <sudeep.dutt@intel.com>
+Description:
+ When read, this entry provides the current state of an Intel
+ MIC device in the context of the card OS. Possible values that
+ will be read are:
+ "ready" - The MIC device is ready to boot the card OS. On
+ reading this entry after an OSPM resume, a "boot" has to be
+ written to this entry if the card was previously shutdown
+ during OSPM suspend.
+ "booting" - The MIC device has initiated booting a card OS.
+ "online" - The MIC device has completed boot and is online
+ "shutting_down" - The card OS is shutting down.
+ "resetting" - A reset has been initiated for the MIC device
+ "reset_failed" - The MIC device has failed to reset.
+
+ When written, this sysfs entry triggers different state change
+ operations depending upon the current state of the card OS.
+ Acceptable values are:
+ "boot" - Boot the card OS image specified by the combination
+ of firmware, ramdisk, cmdline and bootmode
+ sysfs entries.
+ "reset" - Initiates device reset.
+ "shutdown" - Initiates card OS shutdown.
+
+What: /sys/class/mic/mic(x)/shutdown_status
+Date: October 2013
+KernelVersion: 3.13
+Contact: Sudeep Dutt <sudeep.dutt@intel.com>
+Description:
+ An Intel MIC device runs a Linux OS during its operation. This
+ OS can shutdown because of various reasons. When read, this
+ entry provides the status on why the card OS was shutdown.
+ Possible values are:
+ "nop" - shutdown status is not applicable, when the card OS is
+ "online"
+ "crashed" - Shutdown because of a HW or SW crash.
+ "halted" - Shutdown because of a halt command.
+ "poweroff" - Shutdown because of a poweroff command.
+ "restart" - Shutdown because of a restart command.

+What: /sys/class/mic/mic(x)/cmdline
+Date: October 2013
+KernelVersion: 3.13
+Contact: Sudeep Dutt <sudeep.dutt@intel.com>
+Description:
+ An Intel MIC device runs a Linux OS during its operation. Before
+ booting this card OS, it is possible to pass kernel command line
+ options to configure various features in it, similar to
+ self-bootable machines. When read, this entry provides
+ information about the current kernel command line options set to
+ boot the card OS. This entry can be written to change the
+ existing kernel command line options. Typically, the user would
+ want to read the current command line options, append new ones
+ or modify existing ones and then write the whole kernel command
+ line back to this entry.

+Date: October 2013
+KernelVersion: 3.13
+Contact: Sudeep Dutt <sudeep.dutt@intel.com>
+Description:
+ When read, this sysfs entry provides the path name under
+ /lib/firmware/ where the firmware image to be booted on the
+ card can be found. The entry can be written to change the
+ firmware image location under /lib/firmware/.
+
+What: /sys/class/mic/mic(x)/ramdisk
+Date: October 2013
+KernelVersion: 3.13
+Contact: Sudeep Dutt <sudeep.dutt@intel.com>
+Description:
+ When read, this sysfs entry provides the path name under
+ /lib/firmware/ where the ramdisk image to be used during card
+ OS boot can be found. The entry can be written to change
+ the ramdisk image location under /lib/firmware/.
+
+What: /sys/class/mic/mic(x)/bootmode
+Date: October 2013
+KernelVersion: 3.13
+Contact: Sudeep Dutt <sudeep.dutt@intel.com>
+Description:
+ When read, this sysfs entry provides the current bootmode for
+ the card. This sysfs entry can be written with the following
+ valid strings:
+ a) linux - Boot a Linux image.
+ b) flash - Boot an image for flash updates.
+
+What: /sys/class/mic/mic(x)/log_buf_addr
+Date: October 2013
+KernelVersion: 3.13
+Contact: Sudeep Dutt <sudeep.dutt@intel.com>
+Description:
+ An Intel MIC device runs a Linux OS during its operation. For
+ debugging purpose and early kernel boot messages, the user can
+ access the card OS log buffer via debugfs. When read, this entry
+ provides the kernel virtual address of the buffer where the card
+ OS log buffer can be read. This entry is written by the host
+ configuration daemon to set the log buffer address. The correct
+ log buffer address to be written can be found in the System.map
+ file of the card OS.
+
+What: /sys/class/mic/mic(x)/log_buf_len

+What: /sys/class/mic/mic(x)/heartbeat_enable
+Date: March 2015
+KernelVersion: 4.4
+Contact: Ashutosh Dixit <ashutosh.dixit@intel.com>
+Description:
+ The MIC drivers detect and inform user space about card crashes
+ via a heartbeat mechanism (see the description of
+ shutdown_status above). User space can turn off this
+ notification by setting heartbeat_enable to 0 and enable it by
+ setting this entry to 1. If this notification is disabled it is
+ the responsibility of user space to detect card crashes via
+ alternative means such as a network ping. This setting is
+ enabled by default.
