Colin Xu 4ab2932966 drm/i915/gvt: Fix virtual display setup for BXT/APL
commit a5a8ef937cfa79167f4b2a5602092b8d14fd6b9a upstream

Program display related vregs to proper value at initialization, setup
virtual monitor and hotplug.

vGPU virtual display vregs inherit the value from pregs. The virtual DP
monitor is always setup on PORT_B for BXT/APL. However the host may
connect monitor on other PORT or without any monitor connected. Without
properly setup PIPE/DDI/PLL related vregs, guest driver may not setup
the virutal display as expected, and the guest desktop may not be
created.
Since only one virtual display is supported, enable PIPE_A only. And
enable transcoder/DDI/PLL based on which port is setup for BXT/APL.

V2:
Revise commit message.

V3:
set_edid should on PORT_B for BXT.
Inject hpd event for BXT.

V4:
Temporarily disable vfio edid on BXT/APL until issue fixed.

V5:
Rebase to use new HPD define GEN8_DE_PORT_HOTPLUG for BXT.
Put vfio edid disabling on BXT/APL to a separate patch.

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.
