Colin Xu 28e53acd30 drm/i915/gvt: Fix vfio_edid issue for BXT/APL
commit 4ceb06e7c336f4a8d3f3b6ac9a4fea2e9c97dc07 upstream

BXT/APL has different isr/irr/hpd regs compared with other GEN9. If not
setting these regs bits correctly according to the emulated monitor
(currently a DP on PORT_B), although gvt still triggers a virtual HPD
event, the guest driver won't detect a valid HPD pulse thus no full
display detection will be executed to read the updated EDID.

With this patch, the vfio_edid is enabled again on BXT/APL, which is
previously disabled.

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.
