From mboxrd@z Thu Jan 1 00:00:00 1970 From: Petr Mladek Subject: [PATCH 0/3] thermal/intel_powerclamp: Conversion to kthread worker API and new CPU hotplug state Date: Mon, 17 Oct 2016 14:32:49 +0200 Message-ID: <1476707572-32215-1-git-send-email-pmladek@suse.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Jacob Pan , Zhang Rui , Thomas Gleixner Cc: Sebastian Andrzej Siewior , Eduardo Valentin , Tejun Heo , Peter Zijlstra , linux-pm@vger.kernel.org, linux-kernel@vger.kernel.org, Petr Mladek List-Id: linux-pm@vger.kernel.org The kthread worker API enhancements are in 4.9-rc1. Therefore we could finally convert the intel_powerclamp kthreads to it. The API hides a rather tricky code for the sleeping, freezing, and exiting checks. It should help to avoid races and maintain these operations. Sebastian asked me to send also the conversion to the new CPU hotplug state machine on top of the kthread conversion. IMPORTANT: I have tested this on top of 4.9-rc1. But I needed to add ("sched/fair: Fix sched domains NULL deference in select_idle_sibling()") from linux-tip, see https://lkml.kernel.org/r/tip-9cfb38a7ba5a9c27c1af8093fb1af4b699c0a441@git.kernel.org Otherwise, the CPU hotplug failed very often.
