Subject: [PATCH 00/10] cpufreq: Migrate users of policy notifiers to QoS requests
Date: Tue, 16 Jul 2019 15:18:56 +0530	[thread overview]
Message-ID: <cover.1563269894.git.viresh.kumar@linaro.org> (raw)

Hello,

Now that cpufreq core supports taking QoS requests for min/max cpu
frequencies, lets migrate rest of the users to using them instead of the
policy notifiers.

The CPUFREQ_NOTIFY and CPUFREQ_ADJUST events of the policy notifiers are
removed as a result, but we have to add CPUFREQ_CREATE_POLICY and
CPUFREQ_REMOVE_POLICY events to it for the acpi stuff specifically. So
the policy notifiers aren't completely removed.

Boot tested on my x86 PC and ARM hikey board. Nothing looked broken :)

This has already gone through build bot for a few days now.
