Revert "hv_netvsc: report vmbus name in ethtool"

2016-10-29T19:03:14Z

This reverts commit e3f74b841d48 ("hv_netvsc: report vmbus name in ethtool")' because of problem introduced by commit f9a56e5d6a0ba ("Drivers: hv: make VMBus bus ids persistent"). This changed the format of the vmbus name and this new format is too long to fit in the bus_info field of ethtool. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

Drivers: hv: utils: Support TimeSync version 4.0 protocol samples.

2016-09-08T11:53:07Z

This enables support for more accurate TimeSync v4 samples when hosted under Windows Server 2016 and newer hosts. The new time samples include a "vmreferencetime" field that represents the guest's TSC value when the host generated its time sample. This value lets the guest calculate the latency in receiving the time sample. The latency is added to the sample host time prior to updating the clock. Signed-off-by: Alex Ng Signed-off-by: K. Y.

Some VMBus devices are not needed by Linux guest[1][2], and, VMBus channels of Hyper-V Sockets don't really mean usual synthetic devices, so let's suppress the warnings for them.

Revert "Drivers: hv: ring_buffer: count on wrap around mappings in get_next_pkt_raw()"

To deal with the merge conflict between net-next and char-misc trees, revert commit bb08d431a914 from char-misc tree. This commit can be rebased and applied once net-next picks up char-misc changes. Here is the commit log of the reverted patch: "With wrap around mappings in place we can always provide drivers with direct links to packets on the ring buffer, even when they wrap around.

Drivers: hv: Introduce a policy for controlling channel affinity

2016-09-02T15:22:51Z

Introduce a mechanism to control how channels will be affinitized. We will support two policies: 1. HV_BALANCED: All performance critical channels will be dstributed evenly amongst all the available NUMA nodes. Once the Node is assigned, we will assign the CPU based on a simple round robin scheme. 2. HV_LOCALIZED: Only the primary channels are distributed across all NUMA nodes. Sub-channels will be in the same NUMA node as the primary channel. This is the current behaviour. The default policy will be the HV_BALANCED as it can minimize the remote memory access on NUMA machines with applications that span NUMA nodes. Signed-off-by: K. Y.

Drivers: hv: vmbus: Implement a mechanism to tag the channel for low latency

2016-08-31T11:05:41Z

On Hyper-V, performance critical channels use the monitor mechanism to signal the host when the guest posts mesages for the host. This mechanism minimizes the hypervisor intercepts and also makes the host more efficient in that each time the host is woken up, it processes a batch of messages as opposed to just one. The goal here is improve the throughput and this is at the expense of increased latency. Implement a mechanism to let the client driver decide if latency is important. Signed-off-by: K. Y.
