SVEN = „System Visible Event Nexus“ • Infrastructure for low overhead software event tracing • Based on SW instrumentation using an TX-API – Inserted code to indicate what is happening when • SoC/Platform scope, collects traces for – multiple cores (IA, DSP, ...) – user and kernel code Think of SVEN as the SW analog to an airplane black box recorder 9 Copyright© 2013, Intel Corporation. All rights reserved. *Other brands and names are the property of their respective owners. What is a SVEN event • 32 byte in size • Indicates good or poor health of the module timestamp • Standardized set of events ! mod u typ sub • User defined module or API events p a y l o a d 10 Copyright© 2013, Intel Corporation.
