We've gotten access to a Haswell system. How do we get perf with LBR support? It looks like it hasn't been merged into the main line kernel. Are there binaries anywhere? Do we need to upgrade the entire kernel, or just the perf utility? -- 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
