RPSTAT1 is an sgunit register and thus doesn't need forcewake.
MTL_MIRROR_TARGET_WP1 is within an "always on" power domain and thus
doesn't require any forcewake to ensure the register is powered
up and usable. When GT is RC6 the actual frequency reported will be 0.
v2:
- Add bspec index (Anshuman)
- %s/GEN12_RPSTAT1/GT_PERF_STATUS as per bspec
v3: Update Fixes tag
Bspec: 51837, 67651
Fixes: dd08ebf6c352 ("drm/xe: Introduce a new DRM driver for Intel GPUs")

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.
