2013-09-26Drivers: hv: util: Correctly support ws2008R2 and earlierK. Y. Srinivasan
The current code does not correctly negotiate the version numbers for the util driver when hosted on earlier hosts. The version numbers presented by this driver were not compatible with the version numbers supported by Windows Server 2008. Fix this problem. I would like to thank Olaf Hering (ohering@suse.com) for identifying the problem. Reported-by: Olaf Hering <ohering@suse.com> Signed-off-by: K. Y.

2013-09-26hv: use dev_groups for device attributesGreg Kroah-Hartman
This patch is the first in a series that moves the hv bus code to use the dev_groups field instead of dev_attrs, as dev_attrs is going away in future kernel releases. It moves the id sysfs file to the dev_groups structure, and creates the needed show/store functions, instead of relying on one "universal" function for this. By doing this, it removes the need for this to be in a temporary structure. Tested-by: "K. Y.

2013-08-02Drivers: hv: remove HV_DRV_VERSIONOlaf Hering
Remove HV_DRV_VERSION, it has no meaning for upstream drivers. Initially it was supposed to show the "Linux Integration Services" version, now it is not in sync anymore with the out-of-tree drivers available from the MSFT website. The only place where a version string is still required is the KVP command "IntegrationServicesVersion" which is handled by tools/hv/hv_kvp_daemon.c. To satisfy such KVP request from the host pass the current string to the daemon during KVP userland registration. Signed-off-by: Olaf Hering <olaf@aepfle.de> Acked-by: K. Y.

2013-06-03Drivers: hv: vmbus: Implement multi-channel supportK. Y. Srinivasan
Starting with Win8, the host supports multiple sub-channels for a given device. As in the past, the initial channel offer specifies the device and is associated with both the type and the instance GUIDs. For performance critical devices, the host may support multiple sub-channels. The sub-channels share the same type and instance GUID as the primary channel. The number of sub-channels offerrred to the guest depends on the number of virtual CPUs assigned to the guest. The guest can request the creation of these sub-channels and once created and opened, the guest can distribute the traffic across all the channels (the primary and the sub-channels). A request sent on a sub-channel will have the response delivered on the same sub-channel. At channel (sub-channel) creation we bind the channel interrupt to a CPU and with this sub-channel support we will be able to spread the interrupt load of a given device across all available CPUs.

2013-03-15Drivers: hv: Add a new driver to support host initiated backupK. Y. Srinivasan
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.
