From 0e64537917a5b27565b8c479fda83508a6da7b86 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 13 Nov 2021 15:17:02 +0100 Subject: [PATCH] utils/genrandconfig: reduce the maximum "size" of random configurations genrandconfig is used by the Buildroot autobuilders to generate semi-random configurations that we build test. As part of this, we use "make randpackageconfig" to randomize the selection of packages, together with a KCONFIG_PROBABILITY value, which indicates the probabibility for each option to be enabled. This probability is itself randomized, between 1% and 30% for every build. However, with our increasing number of packages (over 2900), when we use a 30% probability for options to be enabled, it means a *lot* of options are enabled, causing very large configurations to be tested. These configurations are not very realistic, and they take ages to build on our autobuilders: we have builds that take 4, 5 or even 7 hours to build. In order to test a larger number of configurations and therefore a larger variety of configurations, this commit reduces the maximum probability to 20%.
