[igt-dev] [IGT] tools/intel_gpu_top: Add support for stdout logging
Tvrtko Ursulin
tvrtko.ursulin at linux.intel.com
Fri Feb 8 10:26:12 UTC 2019
From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>
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.
