What is cachyos bore

General

today is turned on my laptop and i found bore option what is that???

It stands for ‘Burst-Oriented Response Enhancer’ (CPU scheduler) to make your system more responsive. It helps to get better performance for gaming and daily use, etc.

You’ve prob. seen this “Linux-CachyOS-BORE”. It’s often the default or recommended kernel.

default recommended kernel atm is linux-cachyos and not linux-cachyos-bore. There’s some contraversial info about the difference between the two. CachyOS wiki also doesn’t (IMO) nicely explain the difference. Does the linux-cachyos use bore as well? If yes, what is the difference between the two? According to some, the difference is in that that linux-cachyos-bore actually lacks some optimizations that are applied to linux-cachyos. If this is indeed the case, the naming convection sucks (The name: linux-cachyos-bore IMO implies that the only difference is the scheduler).

Wiki page: CachyOS Kernel | CachyOS

The way that reads, assuming it’s up to date, I would assume linux-cachyos-bore is the same as linux-cachyos, except guaranteed to be using BORE scheduler.

Contrast to the description of linux-cachyos-lts, which explicitly states it excludes most of the usual patches, in addition to also using BORE.

The page could really be more clear / consistent though.

I don’t think so. I’m pretty sure it’s using EEVDF.

Wiki doesn’t mention anything (perhaps because it changes sometimes?), but this:

zgrep -i config_sched /proc/config.gz

Does not mention BORE or any other scheduler, and so it’s most likely using the default kernel scheduler, which would be EEVDF.

According to linux-cachyos pkgbuild script:

‘cachyos’ - select ‘CachyOS Default Scheduler (BORE)’

: “${_cpusched:=cachyos}”

I must say this naming convention sucks. It appears linux-cachyos also uses bore, plus contains additional optimizations. You can call me crazy, but I am pretty sure everyone and their mom would assume based on the naming scheme that say linux-cachyos-bore is basically same like linux-cachyos aside from the scheduler. They do some nice work, but have somehow managed to pick even weirder names than Arch does (Not necessarily for the kernels but e.g. -S is “sync” but also install. In the and it is just how I feel about it).
