misc: mic: MIC host and card driver changes to enable VOP

2016-02-10T01:32:37+00:00

This patch modifies the MIC host and card drivers to start using the
VOP driver. The MIC host and card drivers now implement the VOP bus
operations and register a VOP device on the VOP bus. MIC driver stack
documentation is also updated to include the new VOP driver.

misc: mic: Remove MIC X100 card virtio functionality

2016-02-10T01:32:37+00:00

This patch deletes the virtio functionality from the MIC X100 card
driver. A subsequent patch will re-enable this functionality by
consolidating the hardware independent logic in a new Virtio over PCIe
(VOP) driver.

misc: mic: Remove COSM functionality from the MIC card driver

2015-10-04T11:46:06+00:00

Since card side COSM functionality, to trigger MIC device shutdowns
and communicate shutdown status to the host, is now moved into a
separate COSM client driver, this patch removes this functionality
from the base MIC card driver. The mic_bus driver is also updated to
use the device index provided by COSM rather than maintain its own
device index.

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

Intel MIC Card Driver for X100 family.

2013-09-26T20:50:56+00:00

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.
