- Create skeleton and add basic functionality for the Hyper-V compute device driver (dxgkrnl). - Register for PCI and VMBus driver notifications and handle initialization of VMBus channels. - Connect the dxgkrnl module to the drivers/hv/ Makefile and Kconfig - Create a MAINTAINERS entry A VMBus channel is a communication interface between the Hyper-V guest and the host. The are two type of VMBus channels, used in the driver: - the global channel - per virtual compute device channel A PCI device is created for each virtual compute device, projected by the host. The device vendor is PCI_VENDOR_ID_MICROSOFT and device id is PCI_DEVICE_ID_VIRTUAL_RENDER. dxg_pci_probe_device handles arrival of such devices. The PCI config space of the virtual compute device has luid of the corresponding virtual compute device VM bus channel. This is how the compute device adapter objects are linked to VMBus channels. VMBus interface version is exchanged by reading/writing the PCI config space of the virtual compute device. The IO space is used to handle CPU accessible compute device allocations. Hyper-V allocates IO space for the global VMBus channel. Signed-off-by: Iouri Tarassov <iourit@linux.microsoft.com> |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
