From 596f76029ccb6f87c3b049552bd08f5034c41d9c Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Tue, 7 Aug 2018 14:26:20 +0000 Subject: sstate: Add sstate usage summary to the build Currently the user has no indication of how much sstate was already present or that would be used by the build. This change adds some summary information so that the user can see how much reuse is occurring. To fully work it needs some extra information from a recent bitbake commit but this is optional. When combined with bitbake --dry-run this feature can be used to check if sstate would be reused in a build.
