If you want to build a kernel, you might also want to care about the tickles config and the timers config. $ zgrep -i no_hz /proc/config.gz CONFIG_NO_HZ_COMMON=y CONFIG_NO_HZ_IDLE=y # CONFIG_NO_HZ_FULL is not set CONFIG_NO_HZ=y >https://wiki.linuxaudio.org/wiki/system_configuration#cpu_frequency_scaling It doesn't harm to care about the governor, since it could improve performance. I don't think you need a loop to set the governor for all cores. >https://wiki.linuxaudio.org/wiki/system_configuration#hardware_timers This most likely is outdated. $ zgrep -i timer /proc/config.gz # Timers subsystem CONFIG_HIGH_RES_TIMERS=y CONFIG_POSIX_TIMERS=y CONFIG_TIMERFD=y CONFIG_OPROFILE_NMI_TIMER=y CONFIG_HPET_TIMER=y CONFIG_X86_PM_TIMER=y CONFIG_NETFILTER_XT_TARGET_IDLETIMER=m CONFIG_HW_RANDOM_TIMERIOMEM=m CONFIG_HANGCHECK_TIMER=m CONFIG_PPS_CLIENT_KTIMER=m CONFIG_SND_TIMER=m CONFIG_SND_PCM_TIMER=y CONFIG_SND_HRTIMER=m CONFIG_SND_SEQ_HRTIMER_DEFAULT=y CONFIG_LEDS_TRIGGER_TIMER=m CONFIG_IIO_HRTIMER_TRIGGER=m >My new system runs the 4.17.17 kernel along with the rest of Fedora-27. /etc/rc.d/ most likely is an outdated location. What kind of computer are you using, that you care about swappiness? Maybe you distro migrated from the 'audio' group to a 'realtime' group. "@realtime - rtprio 99 @realtime - memlock unlimited" - http://jackaudio.org/faq/linux_rt_config.html 'rtprio 99' sometimes is discussed, but 'memlock unlimited' usually isn't discussed. YMMV! -- pacman -Q linux{,-rt{-pussytoes,-cornflower,,-securityink}}|cut -d\ -f2 4.18.3.arch1-1 4.18_rc8_rt1-1 4.16.18_rt12-1 4.16.18_rt11-1 4.16.18_rt10-1 _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
