[kernel][thread] Wake up only needed cores #266

Closed vishals4gh closed 3 years ago

vishals4gh commented 4 years ago

This change ensures that during thread scheduling only needed cores are woken up as per the thread's CPU affinity rather than all cores. This would avoid un-necessary wakup for other cores from lower power states without having to execute anything.
