From ce3dedc26b9080399c44d86e14aa1704f7bf563a Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 18 Aug 2024 11:03:43 +0200 Subject: [PATCH] utils/genrandconfig: improve logging Right now, genrandconfig just spits out the random messages from the different make invocations, which isn't terribly useful. Instead, let's redirect the output of make invocations to oblivion, and add some more high level logging. As part of this logging, we're interested to see how many iterations were needed to find a valid configuration, so changed the loop logic to count from 0 to 100 instead of from 100 to 0 so that we can easily show the iteration number.
