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

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 patch-set fixes the following issues in the vmbus driver (vmbus_drv.c): Make vmbus driver a platform pci device and cleanup root device management and irq allocation (patches 1/12 through 3/12): 1) Make vmbus driver a platform pci driver. 2) Cleanup root device management. 3) Leverage the pci model for allocating irq. General cleanup of vmbus driver (patches 4/12 though 12/12): 1)

I just took a quick look at the vmbus code, and have the following comments: - why is count_hv_channel() even a function? - your .h files need to be consolidated and renamed. You will need a single hyperv.h file for include/linux/ that will contain some of what the vmbus*.h files have in it, but not all. Please merge things together to have: - include/linux/hyperv.h What is

Further cleanup of the hv drivers. 1) Cleanup reference counting. 2) Handle all block devices using the storvsc driver. I have modified the implementation here based on Christoph's feedback on my earlier implementation. 3) Fix bugs. 4) Accomodate some host side scsi emulation bugs. 5) In case of scsi errors off-line the device. This patch-set further reduces the size of

Greg, A few days ago you applied all the outstanding patches for the Hyper-V drivers. With these patches, I have addressed all of the known review comments for the vmbus driver (and a lot of comments/issues in other drivers as well). I am still hoping I can address whatever other issues/comments there might be with the intention to get the vmbus driver out of staging in the current window.
