From c145624ccc77ffd07a0b4c368c0dfce525e17eac Mon Sep 17 00:00:00 2001 From: Elliot Smith Date: Tue, 8 Mar 2016 11:27:24 +0000 Subject: toaster.bbclass: improve how we gather buildstats for Toaster Clean up the code which gathers buildstats for Toaster, and modify the field names so that the correct parts of the buildstats files are used to derive the CPU usage values. Also derive elapsed time for the build here, rather than in Toaster, as we have ready access to the data in the correct format.
