| Series | [1/3] rtla/osnoise: Use pretty formatting only on interactive tty | expand |
This is a single patch, selected out of a test series. I messed up the subject giving the impression that more patches were to come. Sorry for any inconvenience, Luis On Mon, Jun 10, 2024 at 10:25:28AM -0300, Luis Claudio R.

osnoise top performs background/font color formatting that could make the text output confusing if not on a terminal. Use the changes from commit f5c0cdad6684a ("rtla/timerlat: Use pretty formatting only on interactive tty") as an inspiration to fix this problem. Apply the formatting only if running on a tty, and not in quiet mode.
