config INTEL_MIC_BUS
tristate "Intel MIC Bus Driver"
depends on 64BIT && PCI && X86
help
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
<http://software.intel.com/en-us/mic-developer>.
config SCIF_BUS
tristate "SCIF Bus Driver"
depends on 64BIT && PCI && X86
help
This option is selected by any driver which registers a
device or driver on the SCIF Bus, such as CONFIG_INTEL_MIC_HOST
and CONFIG_INTEL_MIC_CARD.
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

config VOP_BUS
tristate "VOP Bus Driver"
help
This option is selected by any driver which registers a
device or driver on the VOP Bus, such as CONFIG_INTEL_MIC_HOST
and CONFIG_INTEL_MIC_CARD.
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.

config INTEL_MIC_HOST
tristate "Intel MIC Host Driver"
depends on 64BIT && PCI && X86
depends on INTEL_MIC_BUS && SCIF_BUS && MIC_COSM && VOP_BUS
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.

config INTEL_MIC_CARD
tristate "Intel MIC Card Driver"
depends on 64BIT && X86
depends on INTEL_MIC_BUS && SCIF_BUS && MIC_COSM && VOP_BUS
select VIRTIO
help
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.
If you are building a card kernel for an Intel MIC device then
say M (recommended) or Y, else say N. If unsure say N.

config SCIF
tristate "SCIF Driver"
depends on 64BIT && PCI && X86 && SCIF_BUS && IOMMU_SUPPORT
select IOMMU_IOVA
help
This enables SCIF Driver support for the Intel Many Integrated
Core (MIC) family of PCIe form factor coprocessor devices that
run a 64 bit Linux OS. The Symmetric Communication Interface
(SCIF (pronounced as skiff)) is a low level communications API
across PCIe currently implemented for MIC.
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>.
config MIC_COSM
tristate "Intel MIC Coprocessor State Management (COSM) Drivers"
depends on 64BIT && PCI && X86 && SCIF
help
This enables COSM driver support for the Intel Many
Integrated Core (MIC) family of PCIe form factor coprocessor
devices. COSM drivers implement functions such as boot,
shutdown, reset and reboot of MIC devices.
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

config VOP
tristate "VOP Driver"
depends on VOP_BUS
select VHOST_RING
select VIRTIO
help
This enables VOP (Virtio over PCIe) Driver support for the Intel
Many Integrated Core (MIC) family of PCIe form factor coprocessor
devices. The VOP driver allows virtio drivers, e.g. net, console
and block drivers, on the card connect to user space virtio
devices on the host.
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.
