Drivers: hv: Add Hyper-V balloon driver

2012-11-15T23:42:09Z

Add the basic balloon driver. Windows hosts dynamically manage the guest memory allocation via a combination memory hot add and ballooning. Memory hot add is used to grow the guest memory upto the maximum memory that can be allocatted to the guest. Ballooning is used to both shrink as well as expand up to the max memory. Supporting hot add needs additional support from the host. We will support hot add when this support is available. For now, by setting the VM startup memory to the VM max memory, we can use ballooning alone to dynamically manage memory allocation amongst competing guests on a given host. Signed-off-by: K. Y.

Drivers: hv: kvp: Copy the address family information

2012-09-05T19:12:38Z

This is part of the IP injection protocol in that the host expects this field to reflect what addresses (address families) are currently bound to the interface. The KVP daemon is currently collecting this information and sending it to the kernel component. I had overlooked copying this and sending it back to the host. This patch addresses this issue.

hv: vmbus_drv: detect hyperv through x86_hyper

2012-09-04T22:55:34Z

There are two reasons we need to use x86_hyper instead of query_hypervisor_presence(): - Not only hyperv but also other hypervisors such as kvm would set X86_FEATURE_HYTPERVISOR, so query_hypervisor_presence() will return true even in kvm. This may cause extra delay of 5 seconds before failing the probing in kvm guest. - The hypervisor has been detected in init_hypervisor(), so no need to do the work again.
