From c281afe24fc51691e65f59ea66eefa14cbdfa0e7 Mon Sep 17 00:00:00 2001 From: Vincent Guittot Date: Tue, 26 Mar 2024 10:16:14 +0100 Subject: [PATCH] thermal/cpufreq: Remove arch_update_thermal_pressure() arch_update_thermal_pressure() aims to update fast changing signal which should be averaged using PELT filtering before being provided to the scheduler which can't make smart use of fast changing signal. cpufreq now provides the maximum freq_qos pressure on the capacity to the scheduler, which includes cpufreq cooling device. Remove the call to arch_update_thermal_pressure() in cpufreq cooling device as this is handled by cpufreq_get_pressure().
