From 555e0c1ef7ff49ee5ac3a1eb12de4a2e4722f63d Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Thu, 16 Jul 2015 17:42:29 +0200 Subject: perf: Migrate perf to use new tick dependency mask model Instead of providing asynchronous checks for the nohz subsystem to verify perf event tick dependency, migrate perf to the new mask. Perf needs the tick for two situations: 1) Freq events. We could set the tick dependency when those are installed on a CPU context. But setting a global dependency on top of the global freq events accounting is much easier. If people want that to be optimized, we can still refine that on the per-CPU tick dependency level. This patch dooesn't change the current behaviour anyway. 2) Throttled events: this is a per-cpu dependency.
