hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IBC4SJ -------------------------------- The uncore frequency adjustment configuration takes effect at the millisecond level, and the status of devices within the uncore range fluctuates greatly. Increase the polling interval to reduce the impact of the frequency adjustment effective time and smooth the device status fluctuation.
