[PATCH v6 0/4] powercap/rapl: reduce ipi calls and misc clean up
From: Jacob Pan
Date: Wed Feb 24 2016 - 16:33:38 EST
Changes since v5:
- Split changes into seprate patches. No code change.
Changes since V4:
- Deleted unnecessary cpumask_any_and() call, assign first cpu as lead
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@xxxxxxxxxxxxx>)
- Add direct reference of RAPL package for each RAPL domain.
Jacob Pan (4):
cpumask: export cpumask_any_but
powercap/rapl: reduce ipi calls
powercap/rapl: add package reference per domain
powercap/rapl: track lead cpu per package
