* Drivers: hv: remove unused variable in vmbus_recvpacket_raw()Wei Yongjun2013-01-171-2/+0Star
| | | | | | | | The variable userlen is initialized but never used otherwise, so remove the unused variable. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* Drivers: hv: Implement flow management on the send sideK. Y. Srinivasan2013-01-171-2/+10
| | | | | | | | | 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. Signed-off-by: K. Y.

* Drivers: hv: Add state to manage incoming channel interrupt loadK. Y. Srinivasan2013-01-171-1/+1
| | | | | | | | | Add state to bind a channel to a specific VCPU. This will help us better distribute incoming interrupt load. Signed-off-by: K. Y. Srinivasan <kys@microsoft.com> Reviewed-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* Drivers: hv: Change the signature of vmbus_set_event()K. Y. Srinivasan2013-01-171-1/+1
| | | | | | | | | | 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. Signed-off-by: K. Y.

* Staging: hv: move hyperv code out of staging directoryGreg Kroah-Hartman2011-10-111-0/+815
After many years wandering the desert, it is finally time for the Microsoft HyperV code to move out of the staging directory. Or at least the core hyperv bus code, and the utility driver, the rest still have some review to get through by the various subsystem maintainers.
