Date: Thu, 13 Mar 2014 14:22:13 -0700 From: Andi Kleen <andi@...stfloor.org> To: mingo@...nel.org Cc: linux-kernel@...r.kernel.org, peterz@...radead.org, eranian@...gle.com, acme@...hat.com, namhyung@...nel.org, jolsa@...hat.com, Andi Kleen <ak@...ux.intel.com> Subject: [PATCH 2/2] perf, x86: Don't mark DataLA addresses as store From: Andi Kleen <ak@...ux.intel.com> Haswell supports reporting the data address for a range of events, including UOPS_RETIRED.ALL and some load events. Currently these addresses were always marked as stores, which is wrong, as they could be loads too. Change it to NA instead.
