The 2 second sleep can cause the test to fail on very slow network file systems because Perf ends up being killed before it finishes starting up. Fix it by making the leafloop workload end after a fixed time like the other workloads so there is no need to kill it after 2 seconds. Also remove the 1 second start sampling delay because it is similarly fragile. Instead, search through all samples for a matching one, rather than just checking the first sample and hoping it's in the right place.

Needed to add required include directories for the feature detection to succeed. The header tracefs.h is installed either into the include directory /usr/include/tracefs/tracefs.h when using the Makefile, or into /usr/include/libtracefs/tracefs.h when using meson to build libtracefs. The header tracefs.h uses #include <event-parse.h> from libtraceevent, so pkg-config needs to pick the correct include directory for libtracefs and add the one for libtraceevent to succeed. Note that in baa2ca59 the variable LIBTRACEEVENT_DIR was introduced, and now the method to compile against non-standard locations requires PKG_CONFIG_PATH to be set instead, which works for both libtraceevent and libtracefs.

When PMUs have a cpu map in the 'cpus' or 'cpumask' file, perf will try to open events on those CPUs. ARM doesn't remove offline CPUs meaning taking a CPU offline will cause perf commands to fail unless a CPU map is passed on the command line.

The hard-coded metrics is wrongly calculated on the hybrid machine. $ perf stat -e cycles,instructions -a sleep 1 Performance counter stats for 'system wide': 18,205,487 cpu_atom/cycles/ 9,733,603 cpu_core/cycles/ 9,423,111 cpu_atom/instructions/ # 0.52 insn per cycle 4,268,965 cpu_core/instructions/ # 0.23 insn per cycle The insn per cycle for cpu_core should be 4,268,965 / 9,733,603 = 0.44. When finding the metric events, the find_stat() doesn't take the PMU type into account. The cpu_atom/cycles/ is wrongly used to calculate the IPC of the cpu_core. In the hard-coded metrics, the events from a different PMU are only SW_CPU_CLOCK and SW_TASK_CLOCK. They both have the stat type, STAT_NSECS. Except the SW CLOCK events, check the PMU type as well.
