Subject: [PATCH] cpufreq/schedutil: When updating limitations, frequency modulation interval not become invalid.
Date: Sun, 4 Feb 2024 06:09:28 -0800 [thread overview]
Message-ID: <20240204140928.2865-1-sensor1010@163.com> (raw)
If the current frequency scaling policy is schedutil.
echo schedutil > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
This would result in an invalid frequency modulation interval.
In sugov_limit(), sg_policy->limits_changed is set to true.
