commit 13ddc12768ca98d36ec03bfa21a30b3ebc91673d openeuler. The period of the secure timer is set to 3s by BIOS. That means the secure timer interrupt will trigger every 3 seconds. To further decrease the NMI watchdog's effect on performance, this patch set the period of the secure timer base on 'watchdog_thresh'. This variable is initiallized to 10s. We can also set the period at runtime by modifying '/proc/sys/kernel/watchdog_thresh' Signed-off-by: huwentao <huwentao19@h-partners.com> |
