From 0645ab15ed0bf5b17ad510bd72ef589cda542795 Mon Sep 17 00:00:00 2001 From: Nitin Rawat Date: Thu, 20 Jul 2023 15:04:46 +0530 Subject: [PATCH] scsi: ufs: ufs-qcom: Change UFS devfreq timer to delayed Devfreq uses the default DEVFREQ_TIMER_DEFERRABLE mode which uses the deferred timer for scheduling the devfreq load monitor function. This causes the load monitoring to be done only with non-idle CPUs and not making use of the idle CPUs. Hence, use the DEVFREQ_TIMER_DELAYED mode which uses the delayed timer thereby making use of idle CPUs as well for load monitoring.
