[PATCH 0/4] perf: Tasks and irq exclusion

From: Frederic Weisbecker
Date: Fri May 21 2010 - 10:05:47 EST


The new task and irq exclusion handling can let you
confine tracing and profiling to about everything you

May be the only class of event I haven't tested yet is the
breakpoints and non-tracepoint software events.
Otherwise it works fine for hardware and tracepoints.


(Can be pulled there if you think it's fine:

Frederic Weisbecker (4):
irq: Support to compute context on top of a given preempt_count
perf: Add exclude_task perf event attribute
perf: Support for irq exclusion
perf: Support for task/softirq/hardirq exclusion on tools
