From d2e7da5149679b501cdb4b8449bf15e7ae1c0bdb Mon Sep 17 00:00:00 2001 From: Andrey Konovalov Date: Thu, 11 Apr 2013 16:44:26 +0400 Subject: configs: Move CONFIG_PROVE_LOCKING from linaro-base.conf to debug.conf CONFIG_PROVE_LOCKING is an expensive option which adds significant overhead to lock operations. The examples are 5% power consumption increase for vexpress with this option enabled, and improving netperf on the loopback results by ~200% after disabling DEBUG_MUTEXES (DEBUG_MUTEXES is selected by PROVE_LOCKING). Move CONFIG_PROVE_LOCKING to a separate debug.conf fragment, so that it could be enabled only when it is needed.
