From 9e28f7a74581204807f20ae46568939038e327aa Mon Sep 17 00:00:00 2001 From: Adrián Larumbe Date: Sat, 20 May 2023 18:00:35 +0100 Subject: OPP: rate-limit debug messages when no change in OPP is required MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Otherwise, when enabling a debug build and dynamic debug in the kernel, it quickly floods the kernel ring buffer and makes debugging of other subsystems almost impossible, unless manually disabled.
