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.
Example of text output:
Freq MHz IRQ RC6 Power IMC MiB/s RCS/0
BCS/0 VCS/0 VCS/1 VECS/0
req act /s % W rd wr % se wa %
se wa % se wa % se wa % se wa

Looks nice!
If you add '#' to the start of the header lines, one could use something
like the attached shell script to convert the saved output to SVG graphs
with GnuPlot.
Before including the script to igt, it would need to be modified to
adapt to the number of engines, but maybe intel_gpu_top itself could
generate the gnuplot control file when it exits, if given e.g. --gnuplot
argument?
Hello feature creep! :D
I could add gnuplot output mode later, just to keep this stage simpler.
In that case I would prefer that this mode outputs a single file (or
stdout stream) which could be fed to gnuplot directly. Eg. intel_gpu_top
-g -o file.out && gnuplot file.out, or even, intel_gpu_top -g | gnuplot.
Quick googling shows it should be possible to embed the data in the
"control file", I am only not sure about the output filename in the
second example. But anyway, first example should definitely work.
