From 6f5ea752d7c95ba426ca21a6588cae8812bb3e7c Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Fri, 16 Jun 2023 11:18:05 +0200 Subject: [PATCH] ipq806x: set PERFORMANCE as the default cpufreq governor MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Move default cpufreq governor from ONDEMAND to PERFORMANCE. The temp increase is just 2°C and Watt usage the change is minimal in the order of additional millwatt. The SoC and krait in general looks to suffer for some problem with cache scaling. To have better system stability, force cpu freq and cache freq to the max value supported by the system. This follows mvebu platform where cpufreq is broken and cause minimal temp/watt increase. User can still tweak the governor to ondemand using sysfs entry if needed.
