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.

hv: make "monitor_pages" a "real" pointer array

2013-09-26T16:01:16+00:00

monitor_pages was a void pointer, containing an unknown number of arrays that
we just "knew" were a child and parent array of a specific size.  Instead of
that implicit knowledge, let's make them a real pointer, allowing us to have
type safety, and a semblance of sane addressing schemes.

drivers: hv: allocate synic structures before hv_synic_init()

2013-06-24T23:24:17+00:00

We currently allocate synic structures in hv_sync_init(), but there's no way for
the driver to know about the allocation failure and it may continue to use the
uninitialized pointers. Solve this by introducing helpers for allocating and
freeing and doing the allocation before the on_each_cpu() call in
vmbus_bus_init().

Drivers: hv: Capture the host build information

2013-01-17T19:41:49+00:00

Capture the host build information so it can be presented along with the
negotiated vmbus version information.

Drivers: hv: Implement flow management on the send side

2013-01-17T19:41:49+00:00

Implement flow management on the send side. When the sender is blocked, the reader
can potentially signal the sender to indicate there is now room to send.

Drivers: hv: Manage event tasklets on per-cpu basis

2013-01-17T19:39:15+00:00

Now that we can potentially take vmbus interrupts on any CPU, make the
tasklets per-CPU.

Drivers: hv: Get rid of the unused global signaling state

2013-01-17T19:39:15+00:00

Now that we have implemented a per-connection signaling mechanism, get rid
of the global signaling state. For hosts that don't support per-connection
signaling handle, we have moved the global state to be a per-channel state.

Drivers: hv: Setup a mapping for Hyper-V's notion cpu ID

2013-01-17T19:34:37+00:00

On win8 (ws2012), incoming vmbus interrupt load can be spread across all
available VCPUs in the guest. On a per-channel basis, the interrupts can
be bound to specific CPUs. The Linux notion of cpu ID may be different
from that of the hypervisor's. Setup a mapping structure.

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

2013-01-17T19:34:37+00:00

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.

Drivers: hv: Change the signature of vmbus_set_event()

2013-01-17T19:34:36+00:00

In preparation for supporting a per-connection signaling mechanism,
change the signature of vmbus_set_event(). This change is also
needed to implement other aspects of the signaling optimization.
