Subject: [PATCH v2 3/4] cpufreq: Add strict_target to struct cpufreq_policy
Date: Mon, 09 Nov 2020 17:53:53 +0100 [thread overview]
Message-ID: <2826323.52ZM0ncLkd@kreacher> (raw)
In-Reply-To: <13269660.K2JYd4sGFX@kreacher>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Add a new field to be set when the CPUFREQ_GOV_FLAG_STRICT_TARGET
flag is set for the current governor to struct cpufreq_policy, so
that the drivers needing to check CPUFREQ_GOV_FLAG_STRICT_TARGET do
not have to access the governor object during every frequency
transition.
