[PATCH 1/6] cpufreq: Remove per-CPU QoS constraint

From: Pierre Gondois

Date: Mon Jan 26 2026 - 05:21:36 EST


policy->max_freq_req represents the maximum allowed frequency as
requested by the policyX/scaling_max_freq sysfs file. This request
applies to all CPUs of the policy. It is not possible to request
a per-CPU maximum frequency.

Thus, the interaction between the policy boost and scaling_max_freq
settings should be handled by adding a boost specific QoS constraint.
This will be handled in the following patches.

This patch reverts of:
commit 1608f0230510 ("cpufreq: Fix re-boost issue after hotplugging
a CPU")
