GuC provides support to read engine counters to calculate the
engine activity. KMD exposes two counters via the PMU interface to
calculate engine activity
Engine Active Ticks(engine-active-ticks) - active ticks of engine
Engine Total Ticks (engine-total-ticks) - total ticks of engine
Engine activity percentage can be calculated as below
Engine activity % = (engine active ticks/engine total ticks) * 100.
v2: fix cosmetic review comments
add forcewake for gpm_ts (Umesh)
v3: fix CI hooks error
change function parameters and unpin bo on error
of allocate_activity_buffers
fix kernel-doc (Umesh)
use engine activity (Umesh, Lucas)
rename xe_engine_activity to xe_guc_engine_*
fix commit message to use engine activity (Lucas, Umesh)
v4: add forcewake in PMU layer
v5: fix makefile
use drmm_kcalloc instead of kmalloc_array
remove managed bo
skip init for VF
fix cosmetic review comments (Michal)

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 reStructuredText 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.
