2016-02-09	misc: mic: Remove MIC X100 card virtio functionality	Sudeep Dutt	1	-76/+0
	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.

2013-11-27	misc: mic: Fix user space namespace pollution from mic_common.h.	Ashutosh Dixit	1	-4/+3
	Avoid declaring ALIGN() and __aligned() in include/uapi/linux/mic_common.h since they pollute user space namespace. Also, mic_aligned_size() can be simply replaced simply by sizeof() since all structures where mic_aligned_size() is used are declared using __attribute__ ((aligned(8))); -- >From mail from H Peter Anvin about this: On Fri, Nov 08, 2013 H Peter Anvin <h.peter.anvin@intel.com> wrote: Subject: Namespace pollution in mic_common.h This puts two macros, ALIGN() and __aligned(), into arbitrary user space namespace. This really isn't safe or acceptable, especially since those symbols are highly generic. ... When these structures are forced-aligned, they will in fact have padding automatically added by the compiler to an 8-byte boundary anyway, so mic_aligned_size() does nothing. ...

2013-09-26	Intel MIC Card Driver Changes for Virtio Devices.	Ashutosh Dixit	1	-0/+77
	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 Co-author: Sudeep Dutt <sudeep.dutt@intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by: Caz Yokoyama <Caz.Yokoyama@intel.com> Signed-off-by: Dasaratharaman Chandramouli <dasaratharaman.chandramouli@intel.com> Signed-off-by: Nikhil Rao <nikhil.rao@intel.com> Signed-off-by: Harshavardhan R Kharche <harshavardhan.r.kharche@intel.com> Signed-off-by: Sudeep Dutt <sudeep.dutt@intel.com> Acked-by: Yaozu (Eddie) Dong <eddie.dong@intel.com> Reviewed-by: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
