Drivers: hv: vmbus: Don't timeout during the initial connection with host

2014-02-22T21:34:53+00:00

commit 269f979467cf49f2ea8132316c1f00f8c9678f7c upstream.

When the guest attempts to connect with the host when there may already be a
connection with the host (as would be the case during the kdump/kexec path),
it is difficult to guarantee timely response from the host. Starting with
WS2012 R2, the host supports this ability to re-connect with the host
(explicitly to support kexec). Prior to responding to the guest, the host
needs to ensure that device states based on the previous connection to
the host have been properly torn down. This may introduce unbounded delays.
To deal with this issue, don't do a timed wait during the initial connect
with the host.

Drivers: hv: vmbus: Specify the target CPU that should receive notification

2014-02-22T21:34:53+00:00

commit e28bab4828354583bb66ac09021ca69b341a7db4 upstream.

During the initial VMBUS connect phase, starting with WS2012 R2, we should
specify the VPCU in the guest that should receive the notification. Fix this
issue. This fix is required to properly connect to the host in the kexeced
kernel.

drivers: hv: Fix wrong check for synic_event_page

2013-10-16T21:00:09+00:00

The check for calling free_page() on hv_context.synic_event_page[cpu] is the
same for hv_context.synic_message_page[cpu], like a copy-paste error.

Drivers: hv: vmbus: Terminate vmbus version negotiation on timeout

2013-09-26T21:20:22+00:00

commit 666b9adc801ef012612c4e43e0f44b2cdc1979cf terminated vmbus
version negotiation incorrectly. We need to terminate the version
negotiation only if the current negotiation were to timeout.

Drivers: hv: util: Correctly support ws2008R2 and earlier

2013-09-26T21:20:21+00:00

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.

hv: move ringbuffer bus attributes to dev_groups

2013-09-26T16:01:17+00:00

This moves the ringbuffer bus attributes to the dev_groups structure,
deletes the now unneeded struct hv_device_info, and removes some now
unused functions, and variables as everything is now moved to the
dev_groups structure, dev_attrs is no longer needed.

hv: delete struct hv_dev_port_info

2013-09-26T16:01:17+00:00

It's no longer needed, and the struct hv_ring_buffer_debug_info
structure shouldn't be "global" so move it to the local .h file instead.
