[Intel-gfx] [PATCH i-g-t 0/3] More intel_gpu_top improvements

[Intel-gfx] [PATCH i-g-t 0/3] More intel_gpu_top improvements

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Suggestion was received to omit repeating header lines when outputting to a file
and also to add the CVS mode for easy parsing. We have JSON but I guess CVS can
definitely be easier for some use cases.

Tvrtko Ursulin (3):
  intel_gpu_top: Do not repeat header lines in non-interactive output
  intel_gpu_top: Rename STDOUT to TEXT
  intel_gpu_top: Add CVS output format

[Intel-gfx] [PATCH i-g-t 1/3] intel_gpu_top: Do not repeat header lines in non-interactive output

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

If output is redirected to a file, or a pipe, lets not repeat the headers
because that can usually mean user is trying to parse the data later and
so repeated headers are a hindrance.

Hi Tvrtko,

one small nit, see below.

----------------------------------- ^
Remove this initialization (use checkpatch from Linux kernel).

Please correct and resend (you can keep my r-b).

[Intel-gfx] [PATCH i-g-t 2/3] intel_gpu_top: Rename STDOUT to TEXT

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Internal cleanup only - the name text is more accurate given the output
can also go to a file.
