This post follows up to https://lkml.org/lkml/2014/8/11/329. During the discussion of that patch, Ingo Molnar commented in https://lkml.org/lkml/2014/8/18/577.
"The softlockup and hardlockup detection control variables should be in separate flags, inside and outside the kernel - they (should) not relate to each other." Please refer to [PATCH v2 7/9] for a description of the proposed changes of the 'user interface' in /proc/sys/kernel and kernel command line parameters. There are no functional changes between the initial version in https://lkml.org/lkml/2014/10/13/313 and v2. The new version is merely a re-base to the following upstream commits. commit 6e7458a6f074c71e74cda31c483114e65ea0f570 Author: Ulrich Obergfell <[email protected]> Date: Mon Oct 13 15:55:35 2014 -0700 kernel/watchdog.c: control hard lockup detection default commit 9919e39a17381058dd0cdef2f78dbf5619e26474 Author: Ulrich Obergfell <[email protected]> Date: Mon Oct 13 15:55:37 2014 -0700 kvm: ensure hard lockup detection is disabled by default Ulrich Obergfell (9): watchdog: new definitions and variables, initialization watchdog: introduce the proc_watchdog_update() function watchdog: move definition of 'watchdog_proc_mutex' outside of proc_dowatchdog() watchdog: introduce the proc_watchdog_common() function watchdog: introduce separate handlers for parameters in /proc/sys/kernel watchdog: implement error handling for failure to set up hardware perf events watchdog: enable the new user interface of the watchdog mechanism watchdog: clean up some function names and arguments watchdog: introduce the hardlockup_detector_disable() function arch/x86/kernel/kvm.c | 2 +- include/linux/nmi.h | 21 ++-- kernel/sysctl.c | 35 +++++-- kernel/watchdog.c | 277 ++++++++++++++++++++++++++++++++++++-------------- 4 files changed, 240 insertions(+), 95 deletions(-) -- 1.7.11.7 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
