Further cleanup of the vmbus driver: 1) Cleanup the interrupt handler by inlining some code. 2) Ensure message handling is performed on the same CPU that takes the vmbus interrupt. 3) Check for events before messages (from the host). 4) Disable auto eoi for the vmbus interrupt since Linux will eoi the interrupt anyway. 5) Some general cleanup. Regards, K. Y

This group of patches removes all DPRINT from hv_vmbus.ko. It is divided in several patches due to size. All DPRINT calls have been removed, and where needed have been replaced with pr_XX native calls. Many debug DPRINT calls have been removed outright. The amount of clutter this driver prints has been significantly reduced. Signed-off-by: Hank Janssen <hjanssen at microsoft.com>

This patch set removes all un-needed DPRINT and printk calls and replaces the remaining ones with the correct pr_, dev_ and netdev_ calls from hv_vmbus, hv_netvsc, hv_timesource and hv_utils. Several DPRINTS are remaining that will be cleaned up in my next set of patches. They deal with printing out certain debugging that will be implemented slightly differently. The remaining hv_storvsc and

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
