Configuring an RT Kernel

English Open Chat
1

Hello Everyone,

I was trying to find someone who knows how to compile and configure an rt kernel for Leap 42.1. I’m familiar with this process on Debian, but it appears there are several differences as far as the placement of things. I’m trying to use this for audio.

I was looking at rt.wiki.kernel.org, but was wondering if there’s anything specific needed for openSUSE.

Thanks,

Zen

Hi and welcome to the openSUSE Forum
AFAIK, most of this is in the default kernel these days. Have a browse through /boot/config-4.1.<your_kernel>-default

eg;


cat /boot/config-4.1.13-5-default |grep "TIMERS\|HZ"
CONFIG_NO_HZ_COMMON=y
# CONFIG_HZ_PERIODIC is not set
CONFIG_NO_HZ_IDLE=y
# CONFIG_NO_HZ_FULL is not set
CONFIG_NO_HZ=y
CONFIG_HIGH_RES_TIMERS=y
CONFIG_RCU_FAST_NO_HZ=y
# CONFIG_HZ_100 is not set
CONFIG_HZ_250=y
# CONFIG_HZ_300 is not set
# CONFIG_HZ_1000 is not set
CONFIG_HZ=250
CONFIG_MACHZ_WDT=m

I have also found only this.

Hi
That’s for older releases, you could confirm also via the openSUSE Kernel Mailing List;
https://en.opensuse.org/Communicate

Or search the archive;
