This trys to make 'kvmgt' module as self loadable instead of loading by i915/gvt device model. So hypervisor specific module could be stand-alone, e.g only after loading hypervisor specific module, GVT feature could be enabled via specific hypervisor interface, e.g VFIO/mdev. So this trys to use hypervisor module register/unregister interface for that. Hypervisor module needs to take care of module reference itself when working for hypervisor interface, e.g for VFIO/mdev, hypervisor module would reference counting mdev when open and release. This makes 'kvmgt' module really split from GVT device model. User needs to load 'kvmgt' to enable VFIO/mdev interface. v6: - remove unused variable v5: - put module reference in register error path v4: - fix checkpatch warning v3: - Fix module reference handling for device open and release. Unused mdev devices would be cleaned up in device unregister when module unload. v2: - Fix kvmgt order after i915 for built-in case Cc: "Yuan, Hang" <hang.yuan@intel.com> Cc: Alex Williamson <alex.williamson@redhat.com> Cc: "He, Min" <min.he@intel.com> Reviewed-by: Yuan, Hang <hang.yuan@intel.com> Acked-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
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.
