Question: CacULE scheduler by default

[RiverOnVenus]

Hey, I saw this commit today, will the zen kernel always or for a long time have the CacULE scheduler as default?

CONFIG_CACULE_SCHED=y
CONFIG_CACULE_RDB=y
CONFIG_RDB_INTERVAL=19

Regards.

We modified CacULE so it's not enabled by default:

config CACULE_SCHED
        bool "CacULE CPU scheduler"
        default n
        help
          The CacULE CPU scheduler is based on interactivity score mechanism.
          The interactivity score is inspired by the ULE scheduler (FreeBSD
          scheduler).

          If unsure, say N here.

So I'm assuming that enabling CacULE is deliberate and probably a good choice. @heftig can you confirm?

I started using CacULE about three months ago, I can tell that CacULE works so nice on my PC.

Why add CacULE when its repository is archived/unmaintained? Maybe consider BMQ/PDS from project C.

[heftig]

It wasn't unmaintained when we evaluated it.

I will not be using a non-CFS scheduler for linux-zen as I require cgroup scheduling.

[RiverOnVenus]

It is not unmaintained, ptr1337 is continuing to maintain it.

See here.

CacULE has some issues, see #245 .
