From ef627f855d5409051567ddbf3cba7d9be1ab4979 Mon Sep 17 00:00:00 2001 From: Scott Rifenbark Date: Fri, 21 Mar 2014 06:38:21 -0600 Subject: yocto-project-qs, ref-manual: Fixed core number defaults Fixes [YOCTO #2528] The defaults for BB_NUMBER_THREADS and PARALLEL_MAKE are now automatically set to the build host's number of processor cores. I updated the "Building and Image" section in the Quick Start to state that. I also updated the PARALLEL_MAKE variable.
