--- Comment #23 from XiongZhang <xiong.y.zhang at intel.com> ---
LPT pch and LPT_LP pch have different SBI registers, but real pch isn't passed
through to guest in GVT-d, then guest i915 couldn't correctly identify LPT and
LPT_LP pch. Currently guest i915 guess the pch type according to processor
type. This guess may be wrong if ULT/ULX processor with LPT PCH or normal
processor with LPT_LP pch.
In order to fix these corner case, real pch id should be passed from host to
guest, but this isn't a standard, hacker method is needed in QEMU and i915, and
kinds of hacker are rejected by QEMU.
