Use the i915 exported data in /proc/<pid>/fdinfo to show GPU utilization
per DRM client.
Example of the output:
intel-gpu-top: Intel Tigerlake (Gen12) @ /dev/dri/card0 - 220/ 221 MHz
70% RC6; 0.62/ 7.08 W; 760 irqs/s

v2:
* Removed hardcoded array size from client add/update by passing in
drm_fd_info directly.
* Added some asserts and simplified a couple expressions. (Umesh)

Similarly to how top(1) handles SMP, we can default to showing engines of
a same class as a single bar graph entry.
To achieve this a little bit of hackery is employed. PMU sampling is left
as is and only at the presentation layer we create a fake set of engines,
one for each class, summing and normalizing the load respectively.
v2:
* Fix building the aggregated engines.
* Tidy static variable handling.

In intel_gpu_top device path was hard coded for integrated GPU.
With this patch we:
* use igt_device_scan library for device scanning,
* make discrete GPU the default one,
* provided options for card selection.
v2:
* explicitly set ret to EXIT_SUCCESS after all the other uses
* fix use after free of opt_device (Tvrtko)
* use EXIT_FAILURE instead of "1" (Tvrtko)

Two new output modes are added: listing of text data to standard out (-l
on the command line), and dumping of JSON formatted records (-J), also to
standard out.
The first mode is selected automatically when non-interactive standard out
is detected.

intel-gpu-top is a dangerous tool which can hang machines due unsafe mmio
register access. This patch rewrites it to use only PMU.
Only overall command streamer busyness and GPU global data such as power
and frequencies are included in this new version.
For access to more GPU functional unit level data, an OA metric based tool
like gpu-top should be used instead.
v2:
* Sort engines by class and instance.
* Do not wait for one sampling period to display something on screen.
* Move code out of the asserts. (Rinat Ibragimov)
* Continuously adapt to terminal size. (Rinat Ibragimov)
v3:
* Change layout and precision of some field. (Chris Wilson)
Eero Tamminen:
* Use more user friendly engine names.
* Don't error out if a counter is missing.
* Add IMC read/write bandwidth.
* Report minimum required kernel version.
v4:
* Really support 4.16 by skipping of missing engines.
* Simpler and less hacky float printing.
* Preserve copyright header. (Antonio Argenziano)
* Simplify engines_ptr macro. (Rinat Ibragimov)
v5:
* Get RAPL unit from sysfs.
* Consolidate sysfs paths with a macro.
* Tidy error handling by carrying over and reporting errno.
* Check against console height on all prints.
* More readable minimum kernel version message. (Eero Tamminen)
* Column banner for per engine stats. (Eero Tamminen)
v6:
* Man page update. (Eero Tamminen)

intel_reg.rst was the first man page written in reStructuredText. Follow
suit with the rest of the man pages.
Add a generated defs.rst include file for definitions such as
intel-gpu-tools version. This replaces the MAN_SUBSTS sed script
substitutions from xorg-macros for old man pages.
