I don't see any support in streamline_config.pl for Kconfig symbols and/or modules whose names have changed. Trying to do something like that would be a never-ending job (a la job security). At least it gave you a warning that it couldn't find a Kconfig symbol for that module. >From your original email: | I'm going to assume it has something to do with the naming and it's | supposed to be associated with "Intel/AMD rapl performance events | (CONFIG_PERF_EVENTS_INTEL_RAPL)" which I already have set to 'Y'. Yes, commit fd3ae1e1587d64ef8cc8e361903d33625458073e changed the module name since it now supports both Intel and AMD. | Right below that, I also get 'Use of uninitialized value | $ENV{"LMC_KEEP"} in split at ./scripts/kconfig/streamline_config.pl | line 596.', but again that is the sort of thing that may warrant a new | email specific to localmodconfig author(s).
