hv: remove the per-channel workqueue

2015-04-03T14:18:02Z

It's not necessary any longer, since we can safely run the blocking message handlers in vmbus_connection.work_queue now. Signed-off-by: Dexuan Cui Cc: K. Y. Srinivasan Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Drivers: hv: vmbus: Suport an API to send packet with additional control

2015-03-02T03:31:47Z

Implement an API that gives additional control on the what VMBUS flags will be set as well as if the host needs to be signalled. This API will be useful for clients that want to batch up requests to the host. Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Drivers: hv: vmbus: Suport an API to send pagebuffers with additional control

2015-03-02T03:31:47Z

Implement an API for sending pagebuffers that gives more control to the client in terms of setting the vmbus flags as well as deciding when to notify the host. This will be useful for enabling batch processing. Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Drivers: hv: vmbus: Use a round-robin algorithm for picking the outgoing channel

2015-03-02T03:31:47Z

The current algorithm for picking an outgoing channel was not distributing the load well. Implement a simple round-robin scheme to ensure good distribution of the outgoing traffic. Signed-off-by: K. Y. Srinivasan Reviewed-by: Long Li Signed-off-by: Greg Kroah-Hartman

Drivers: hv: vmbus: Introduce a function to remove a rescinded offer

2015-03-02T03:31:02Z

In response to a rescind message, we need to remove the channel and the corresponding device. Cleanup this code path by factoring out the code to remove a channel. Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Drivers: hv: vmbus: Add support for the NetworkDirect GUID

2015-03-02T03:30:08Z

NetworkDirect is a service that supports guest RDMA. Define the GUID for this service. Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

Drivers: hv: vmbus: rename channel work queues

2015-03-02T03:29:05Z

All channel work queues are named 'hv_vmbus_ctl', this makes them indistinguishable in ps output and makes it hard to link to the corresponding vmbus device. Rename them to hv_vmbus_ctl/N and make vmbus device names match, e.g. now vmbus_1 device is served by hv_vmbus_ctl/1 work queue. Signed-off-by: Vitaly Kuznetsov Signed-off-by: K. Y.

Drivers: hv: rename sc_lock to the more generic lock

2015-01-25T17:18:00Z

sc_lock spinlock in struct vmbus_channel is being used to not only protect the sc_list field, e.g. vmbus_open() function uses it to implement test-and-set access to the state field. Rename it to the more generic 'lock' and add the description. Signed-off-by: Vitaly Kuznetsov Signed-off-by: K. Y. Srinivasan Acked-by: Jason Wang Signed-off-by: Greg Kroah-Hartman

Drivers: hv: vmbus: Support a vmbus API for efficiently sending page arrays

2015-01-25T17:17:58Z

Currently, the API for sending a multi-page buffer over VMBUS is limited to a maximum pfn array of MAX_MULTIPAGE_BUFFER_COUNT. This limitation is not imposed by the host and unnecessarily limits the maximum payload that can be sent. Implement an API that does not have this restriction. Signed-off-by: K. Y.

hyperv: Add support for vNIC hot removal

2014-12-09T01:24:11Z

This patch adds proper handling of the vNIC hot removal event, which includes a rescind-channel-offer message from the host side that triggers vNIC close and removal. In this case, the notices to the host during close and removal is not necessary because the channel is rescinded. This patch blocks these unnecessary messages, and lets vNIC removal process complete normally. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller
