From 23d5efb4af7603e217ee634a5bb1934c41059106 Mon Sep 17 00:00:00 2001 From: William Cohen <wcohen@redhat.com> Date: Tue, 30 Jan 2018 22:28:13 -0500 Subject: [PATCH 093/105] perf vendor events aarch64: Add JSON metrics for ARM Cortex-A53 Processor Git-commit: 0b7c1528fb741803396da68a9d8d285ff7db731c Patch-mainline: v4.16-rc2 References: fate#326417 Add JSON metrics for ARM Cortex-A53 Processor. Unlike the Intel processors there isn't a script that automatically generated these files. The patch was manually generated from the documentation and the previous oprofile ARM Cortex ac53 event file patch I made. The relevant documentation is in the "12.9 Events" section of the ARM Cortex A53 MPCore Processor Revision: r0p4 Technical Reference Manual. The ARM Cortex A53 manual is available at: http://infocenter.arm.com/help/topic/com.arm.doc.ddi0500g/DDI0500G_cortex_a53_trm.pdf Use that to look for additional information about the events.
