> TSC Frequency For All: Better Profiling and Benchmarking

Have you ever tried using LLVM’s X-Ray profiling tools to make some flame graphs, but gotten obscure errors like: ==65892==Unable to determine CPU frequency for TSC accounting. ==65892==Unable to determine CPU frequency. Or worse, have you profiled every function in an application, only to find the sum of all function runtimes accounted for ~15 minutes […]
