This option is selected by any driver which registers a
|
|
device or driver on the MIC Bus, such as CONFIG_INTEL_MIC_HOST,
|
|
CONFIG_INTEL_MIC_CARD, CONFIG_INTEL_MIC_X100_DMA etc.

|
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.
|
|
|
|
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

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.

This enables card driver support for the Intel Many Integrated

Core (MIC) device family. The card driver communicates shutdown/

crash events to the host and allows registration/configuration of

virtio devices. Intel MIC X100 devices are currently supported.
