Drivers: hv: vmbus: Negotiate version 3.0 when running on ws2012r2 hosts

2014-06-07T20:25:35Z

commit 03367ef5ea811475187a0732aada068919e14d61 upstream. Only ws2012r2 hosts support the ability to reconnect to the host on VMBUS. This functionality is needed by kexec in Linux. To use this functionality we need to negotiate version 3.0 of the VMBUS protocol. Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

drivers/video: add Hyper-V Synthetic Video Frame Buffer Driver

2013-04-29T22:54:26Z

This is the driver for the Hyper-V Synthetic Video, which supports screen resolution up to Full HD 1920x1080 on Windows Server 2012 host, and 1600x1200 on Windows Server 2008 R2 or earlier. It also solves the double mouse cursor issue of the emulated video mode. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y.

Drivers: hv: Add a new driver to support host initiated backup

2013-03-15T19:12:36Z

This driver supports host initiated backup of the guest. On Windows guests, the host can generate application consistent backups using the Windows VSS framework. On Linux, we ensure that the backup will be file system consistent. This driver allows the host to initiate a "Freeze" operation on all the mounted file systems in the guest. Once the mounted file systems in the guest are frozen, the host snapshots the guest's file systems. Once this is done, the guest's file systems are "thawed". This driver has a user-level component (daemon) that invokes the appropriate operation on all the mounted file systems in response to the requests from the host. The duration for which the guest is frozen is very short - a few seconds. During this interval, the diff disk is comitted. In this version of the patch I have addressed the feedback from Olaf Herring. Also, some of the connector related issues have been fixed. Signed-off-by: K. Y.

Drivers: hv: vmbus: Consolidate all offer GUID definitions in hyperv.h

2013-01-25T19:17:31Z

Consolidate all GUID definitions in hyperv.h and use these definitions in implementing channel bindings (as far as interrupt delivery goes). Signed-off-by: K. Y. Srinivasan Reviewed-by: Haiyang Zhang Signed-off-by: Greg Kroah-Hartman

Drivers: hv: Enable protocol negotiation with win8 hosts

2013-01-17T19:41:49Z

Now that we have implemented all of the Win8 (WS2012) functionality, negotiate Win8 protocol with the host. Signed-off-by: K. Y. Srinivasan Reviewed-by: Haiyang Zhang Signed-off-by: Greg Kroah-Hartman

Drivers: hv: Add state to manage incoming channel interrupt load

2013-01-17T19:39:14Z

Add state to bind a channel to a specific VCPU. This will help us better distribute incoming interrupt load. Signed-off-by: K. Y. Srinivasan Reviewed-by: Haiyang Zhang Signed-off-by: Greg Kroah-Hartman

Drivers: hv: Manage signaling state on a per-connection basis

2013-01-17T19:34:37Z

The current code has a global handle for supporting signaling of the host from guest. Make this a per-channel attribute as on some versions of the host we can signal on per-channel handle. Signed-off-by: K. Y. Srinivasan Reviewed-by: Haiyang Zhang Signed-off-by: Greg Kroah-Hartman

2013-01-17T19:34:36Z

The "offfer" message sent by the host has been extended in win7 (ws2008 R2). Add/modify state to reflect this extension. All these changes are backward compatible. Signed-off-by: K. Y. Srinivasan Reviewed-by: Haiyang Zhang Signed-off-by: Greg Kroah-Hartman
