From 76ac8275f296b49c58f684825543bf4eb85d43d0 Mon Sep 17 00:00:00 2001 From: "Chen, Gong" <gong.chen@linux.intel.com> Date: Wed, 11 Jun 2014 13:54:04 -0700 Subject: [PATCH] trace, RAS: Add basic RAS trace event To avoid confuision and conflict of usage for RAS related trace event, add an unified RAS trace event stub. Start a RAS subsystem menu which will be fleshed out in time, when more features get added to it.
