Hello, The following patches are a solution to a problem we have encountered when using the Xen hypervisor: - Need Pxx/Cxx states to save on power consumption when using Xen (we do want those datacenters to consume less power!), - Also need to figure out the Turbo mode so that the scheduler can properly boost a core for CPU bound guests. In essence the Xen hypervisor requires that

Further cleanup of the hv drivers: 1) Continue to cleanup our drivers to conform to the Linux Driver Model. 2) Fix some long standing bugs with regards to unloading and reloading the drivers - block, net and stor. 3) VMBUS is an ACPI enumerated device; make VMBUS an ACPI bus driver. 4) Get rid of channel polling code; instead the channel receive paths will be purely interrupt

This is a resend of the patches yet to be applied. This patch-set addresses some of the bus/driver model cleanup that Greg sugested over the last couple of days. In this patch-set we deal with the following issues: 1) Cleanup error handling in the vmbus_probe() and vmbus_child_device_register() functions. Fixed a bug in the probe failure path as part of this cleanup. 2) The Windows

This patch-set addresses some of the bus/driver model cleanup that Greg sugested over the last couple of days. In this patch-set we deal with the following issues: 1) Cleanup unnecessary state in struct hv_device and struct hv_driver to be compliant with the Linux Driver model. 2) Cleanup the vmbus_match() function to conform with the Linux Driver model. 3) Cleanup error

This is a rebase/resend of earlier patches. I skipped the pure cosmetic patches for now. Mostly this is consolidation earlier changes, removing dead code etc. The important part is the change for allowing a vmbus channel to get callback directly in interrupt mode; this is necessary for NAPI support.
