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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.

Host prints lots of untracked MMIO at 0x4653c when creating linux guest. "gvt: vgpu 2: untracked MMIO 0004653c len 4" GEN9_CLKGATE_DIS_4 (0x4653c) is accessed by i915 for gmbus clockgating. However vgpu doesn't support any clockgating powergating operations on related mmio access trap so need add it to default handler. GEN9_CLKGATE_DIS_4 is accessed in bxt_gmbus_clock_gating() which only applies to GEN9_LP so doens't show the warning on other platforms. The solution is to add it to default handler init_bxt_mmio_info(). Reviewed-by:He, Min <min.he@intel.com> Signed-off-by:
