Hi Alex, Thank you very much for running the below benchmark on blocked_load+runnable_load:) Just a few queries. How did you do the wake up balancing? Did you iterate over the L3 package looking for an idle cpu? Or did you just query the L2 package for an idle cpu? I think when you are using bloc

Btw, not sure if any of you have seen the 0-day kbuild setup that intel has.. https://lists.01.org/mailman/listinfo/kbuild runs various builds for different archs on every commit with different configs, randconfig, etc. And various checks with sparse, smatch, etc. Seems kinda useful, and would
