Subject: [patch 0/4] x86/perf/intel/cstate: Fix cpu hotplug handling and make it modular
Date: Sun, 20 Mar 2016 18:59:01 -0000 [thread overview]
Message-ID: <20160320185527.763205536@linutronix.de> (raw)
The perf cstate driver is yet another trainwreck vs. cpu hotplug handling. The
hotplug code is not only disfunctional, it's also a uncomprehensible mess.
The following series fixes the hotplug functionality, sanitizes error handling
and makes the driver modular.
It depends on Kans modularization support for the uncore and rapl drivers:

http://lkml.kernel.org/r/1458462817-2475-2-git-send-email-kan.liang@intel.com
as it uses Kconfig and Makefile which get introduced by those patches.
Thanks,
tglx
