AMD Instruction Based Sampling (IBS) is a hardware performance monitoring mechanism that is available on AMD CPUs starting with the Family 10h generation of Instruction-Based Sampling: A New PerformanceAnalysis Technique for AMD Family 10h ProcessorsPaul J. DrongowskiAMD CodeAnalyst ProjectAdvanced Micro Devices CodeAnalyst uses specific hardware profiling techniques which are designed to work with AMD processors, as well as a timer-based profiling technique which Perf integrates both of these methods. Instruction-Based Sampling (AMD64 only). On AMD processors, however, it is mapped to the hardware eventInstruction-Based Sampling (IBS) is a hardware mechanism that improves the accuracy of profiles. IBS is supported by AMD Family 10h processors.
