From 97450eb909658573dcacc1063b06d3d08642c0c1 Mon Sep 17 00:00:00 2001 From: Vincent Guittot Date: Tue, 26 Mar 2024 10:16:16 +0100 Subject: sched/pelt: Remove shift of thermal clock The optional shift of the clock used by thermal/hw load avg has been introduced to handle case where the signal was not always a high frequency hw signal. Now that cpufreq provides a signal for firmware and SW pressure, we can remove this exception and always keep this PELT signal aligned with other signals.
