Description:

I noticed that CONFIG_SCHED_THERMAL_PRESSURE was unset on the 5.7 master branch. I believe this is worth having it on, based on https://lwn.net/Articles/788380/ (especially for laptops) and Internet gossips of improved performance. Thanks in advance!

The thermal pressure is always 0 on non-ARM platforms.

Thanks for a quick reply! Thanks, I didn't know that. I glanced through git repo (https://github.com/torvalds/linux/blob/0fe5f9ca223573167c4c4156903d751d2c8e160e/include/linux/sched/topology.h#L230 ?) and sadly, you're right. Thank you very much and sorry to have bothered you!
