"The min_granularity setting was renamed to base_slice in this commit in v6 kernel.
The comment says it scales with CPU count and the comment is incorrect. I wonder whether kernel developers are aware of that mistake as they are rewriting the scheduler!
- Official comments in the code says it’s scaling with log2(1+cores) but it doesn’t.
- All the comments in the code are incorrect.
- Official documentation and man pages are incorrect.
- Every blog article, stack overflow answer and guide ever published about the scheduler is incorrect."
this is a very misleading headline and does not reflect reality. the linux kernel absolutely uses more than 8 cores. there may be some timing changes that cap out at 8 cores. it’s really not the big deal the headline and article suggests.
