Next: [PATCH 5/5] perf: Support for task/softirq/hardirq exclusion on tools
From: Frederic Weisbecker on 9 Jun 2010 23:50 Here is the new version of per context exclusion, based on hooks on irq_enter/irq_exit. I haven't observed slowdowns but I haven't actually measured the impact. It's pullable from: git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git perf/exclusion-3 It's against latest tip:perf/core. Thanks.
