misc: mic: SCIF open close bind and listen APIs

2015-05-24T19:13:36+00:00

SCIF character device file operations and kernel APIs for opening and
closing a user and kernel mode SCIF endpoint. This patch also enables
binding to a SCIF port and listening for incoming SCIF connections.

misc: mic: SCIF Hardware Bus

2015-05-24T19:13:36+00:00

The SCIF hardware bus abstracts the low level hardware driver details
like interrupts and mapping remote memory so that the same SCIF driver
can work without any changes with the MIC host or card driver as long
as the hardware bus operations are implemented. The SCIF hardware
device is registered by the host and card drivers on the SCIF hardware
bus resulting in probing the SCIF driver.

misc: mic: add a bus driver for virtual MIC devices

2014-07-12T01:27:56+00:00

This MIC virtual bus driver takes the responsibility of creating all
the virtual devices connected to the PCIe device on the host and the
platform device on the card. The MIC bus hardware operations provide
a way to abstract certain hardware details from the base physical devices.
Examples of devices added on the MIC virtual bus include host DMA and card DMA.
This abstraction enables using a common DMA driver on host and card.

Kconfig: Remove useless "default N" lines

2014-02-20T13:38:06+00:00

A number of Kconfig entries default to (uppercase) "N". It was clearly
intended to use "default n". But since (lowercase) "n" is the default
anyway, these lines might as well be removed.

misc: mic: depend on X86 for both host and card drivers.

2013-09-28T00:20:19+00:00

This fixes build failures seen on certain non X86 architectures.
The card driver should correctly always depend on X86. The host
driver can potentially work on non X86 architectures although
it has never been built or validated in such configurations.
The host driver dependency on X86 can be removed at some point
in the future but this workaround is required for now.

Intel MIC Card Driver Changes for Virtio Devices.

2013-09-26T20:52:24+00:00

This patch introduces the card "Virtio over PCIe" interface for
Intel MIC. It allows virtio drivers on the card to communicate with their
user space backends on the host via a device page. Ring 3 apps on the host
can add, remove and configure virtio devices. A thin MIC specific
virtio_config_ops is implemented which is borrowed heavily from previous
similar implementations in lguest and s390 @
drivers/lguest/lguest_device.c
drivers/s390/kvm/kvm_virtio.c
