| |
Add a test for hyphenated events that are common with Intel's icelake topdown events.
Try to tidy the existing cputopo code and make it more consistent with the sysfs ABI. Refactor the #smt_on literal parsing into a general literal token that we can use for more literals. This is then used for num_cpus, num_cores, num_dies and num_packages literals that use the existing topology code. Finally, a source_count function is added which is used to determine the number of events contributing to an aggregate event. The intent for these new literals and function is for them to be used in upcoming metrics.
v2. Split the handle_id function refactor out of adding the source_count function as suggested-by Jiri Olsa <jolsa@kernel.org>.
