Subject: [PATCH v4 0/2] powercap/rapl: reduce ipi calls and misc clean up
Date: Fri, 19 Feb 2016 12:37:31 -0800 [thread overview]
Message-ID: <1455914253-18138-1-git-send-email-jacob.jun.pan@linux.intel.com> (raw)
Changes since V3:
- Avoid for_each_online_cpu() search for per package MSR access. This
is achieved by tracking a per package lead cpu via cpumask_xx() calls.
(suggested by Thomas Gleixner <tglx@linutronix.de>)
- Add direct reference of RAPL package for each RAPL domain.
This patch optimize remote IPI calls for MSR access.
