http://stackoverflow.com/questions/4956206/change-linux-kernel-timer So, is CONFIG_HIGH_RES_TIMERS set in Leap's kernel-default? And if so, does it mean that the various Hz settings are not relevant? # zgrep TIMERS /proc/config.gz CONFIG_HIGH_RES_TIMERS=y
OTOH, uname on Leap lists PREEMPT. So maybe the low latency RT timers are enabled? Even my ancient 12.3 -desktop kernel lists PREEMPT. # zgrep PREEMP /proc/config.gz CONFIG_PREEMPT_RCU=y CONFIG_PREEMPT_NOTIFIERS=y # CONFIG_PREEMPT_NONE is not set # CONFIG_PREEMPT_VOLUNTARY is not set CONFIG_PREEMPT=y CONFIG_PREEMPT_COUNT=y # CONFIG_DEBUG_PREEMPT is not set # CONFIG_PREEMPT_TRACER is not set
The -default kernel didn't used to have PREEMPT, but it was enabled in kernel-default for Leap.
Could you please give the version of the '-default kernel' you state that didn't have 'PREEMPT' set?
Sure: 3.7.10-1.45-default in openSUSE 12.3 for instance. 3.16.7-21-default in openSUSE 13.2 for instance. -- Per Jessen, Zürich (9.9°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
