Xiong Zhang 65eff27233 drm/i915/gvt: Disable primary/sprite/cursor plane at virtual display initialization
Much error exist in host dmesg during guest boot up with loca display
enabled.
gvt: vgpu 1: invalid range gmadr 0x0 size 0x0

This error happens when qemu get dmabuf info in case that the virtual
display plane is enabled but its base address is an invalid 0, such
case may be true before guest enable its plane. At this moment, its
state is copied from host where the plane may be enabled.

This patch disable primary/sprite/cursor plane at virtual display
initialization, so intel_vgpu_decode_primary/cursor/sprite could
return early as plane is disabled, then plane base check is skipped and
error message disapper.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
