Description

Several proposals have been tried to change the policy of the wake up path regarding the selection of an idle CPU in the scheduler:
- Consider new topology levels
- Speedup and optimize idle cores and/or CPUs selection
- Better estimate how much effort worth spending to look for an idle CPUs
- and more others
This talk will summarize the current ongoing proposals and discuss the best way to move forward

I agree to abide by the anti-harassment policy I agree
