From: Yann E. MORIN Date: Sat, 17 Aug 2019 17:18:27 +0000 (+0200) Subject: support/graph-size: add option to change percentage to group in Others X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e9cdabee71378243680ac43b5f1655567483dd1d;p=buildroot.git support/graph-size: add option to change percentage to group in Others Currently, we group packages that contribute less then 1%, into the "Other" category. However, in some cases, there can be a lot of very comparatively small packages, and they may not exceed this limit, and so only the "Others" category would be displayed, which is not nice. Conversely, if there are a lot of packages, most of which only so slightly exceeding this limit, then we get all of them in the graph, which is not nice either. Add a way for the developers to pass a different cut-off limit. As for the dependency graph which has BR2_GRAPH_DEPS_OPTS, add the environment variable BR2_GRAPH_SIZE_OPTS to carry those extra option (in preparation for more to come, later).
