Subject: can the idle value of /proc/stat decrease?
Date: Mon, 28 Dec 2020 15:54:12 +0800	[thread overview]
Message-ID: <a32dfe3c-8821-77c3-23dd-809b659d2e4f@huawei.com> (raw)
In-Reply-To: <1ad49a62-41dd-cdcc-2f8c-b7a2ad67c3b6@huawei.com>

Our recent test shows that the idle value of /proc/stat can decrease.
Is this an unreported bug? or it has been reported and the solution is 
waiting to get merged.

The results of the two readings from /proc/stat are shown as below, the 
interval between the two readings is 150 ms:

cat /proc/stat
cpu0 5536 10 14160 4118960 0 0 227128 0 0 0

cat /proc/stat
cpu0 5536 10 14160 4118959 0 0 227143 0 0 0
