We've seen some reproducibility issues on the autobuilder in perf where the size of the python module varies slightly between systems. After some head scratching and removing the --quiet option to the python module build, you can see it using -Lrecipe-sysroot-native in the linking commandline for the module. This means it is linking against the native library on systems where that works, skipping it and using the target one otherwise, probably with warnings in logs we've not seen. The fix is to inherit the python3targetconfig class which ensures that the target sysroot is used, then the byte differences between the builds go away and things are sane(r) again.

DESCRIPTION = "Performance counters for Linux are a new kernel-based \
|
|
subsystem that provide a framework for all things \
|
|
performance analysis. It covers hardware level \
|
|
(CPU/PMU, Performance Monitoring Unit) features \
|
|
and software features (software counters, tracepoints) \
|
|
as well."
