Cacule On Linux 5.16+ Not Being Applied #410

Closed Orangian closed 2 years ago

Orangian commented 2 years ago

Hi, I noticed that the CacULE scheduler was not available for 5.16. It appears that the original repository was archived, however, someone else has maintained it here. If possible, would you all consider using this new fork of CacULE to support it on newer Linux versions?

ptr1337 commented 2 years ago

It was available since 5.15. Also the orginal creator of cacule is back in the team and maintain the cacule patches there.

Orangian commented 2 years ago

Ah, I see. I only did a cursory glance of that repository (and the situation as a whole) so I didn't realize that. If that is the case, is it possible for linux-tkg integrate CacULE for the more recent versions, or is there another issue?

ptr1337 commented 2 years ago

No there is no issue. Maybe add it to the community patches or just use it at userpatch :)

Orangian commented 2 years ago

Alrighty, thanks!

Digging deeper into this is very interesting. In commit #2d603642dab724bf2c059560ab0cf0bc0aa5b1bc it appears that TKG attempted to allow for its use above 5.15, however, when actually going to do so, the script does not properly run, and says that CacULE is not available for anything above 5.15. I think this is due to lines 164-167 in linux-tkg/linux-tkg-config/prepare, which contain the following:

elif [ "$_basever" = "516" ]; then _avail_cpu_scheds=("pds" "bmq" "cfs") elif [ "$_basever" = "517" ]; then _avail_cpu_scheds=("pds" "bmq" "cfs") Marking cacule as being unavailable for 5.16 or 5.17. In addition, line 21 in the README.md should be updated from - CacULE by Hamad Marri: [code repository](https://github.com/hamadmarri/cacule-cpu-scheduler) to - CacULE by Hamad Marri: [code repository](https://github.com/CachyOS/cacule-cpu-scheduler)

I'll make a pull request to fix these issues.
