This patch does the following: a) Initializes the Intel MIC X100 platform device and driver. b) Sets up support to handle shutdown requests from the host. c) Maps the device page after obtaining the device page address from the scratchpad registers updated by the host. d) Informs the host upon a card crash by registering a panic notifier. e) Informs the host upon a poweroff/halt event.

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
