perf vendor events aarch64: Add JSON metrics for ARM Cortex-A53 Processor
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.
