From c68d224e5ed15605e651e2482c6ffd95915ddf58 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Mon, 8 Apr 2019 10:32:51 -0700 Subject: perf/core: Add perf_pmu_resched() as global function This patch add perf_pmu_resched() a global function that can be called to force rescheduling of events for a given PMU. The function locks both cpuctx and task_ctx internally. This will be used by a subsequent patch.
