We would like to avoid adding more custom events like these. They were very convenient but they steal the kernel event type space. They are deemed for removal in the long term. Another idea to achieve what you want would be to create a new perf event header feature, like HEADER_TRACE_INFO or HEADER_BUILD_ID are. Then use that to create a space in the perf file to save that couple of clocks initial values. -- To unsubscribe from this list: send the line "unsubscribe linux-perf-users" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
