Subject: [PATCH 0/6] perf trace: Add filter support
Date: Mon, 07 Sep 2009 16:11:57 +0800 [thread overview]
Message-ID: <4AA4C04D.1050201@cn.fujitsu.com> (raw)
This patchset adds filter support for perf counter, so not all
profile events are recorded but only those match the filters
we set.
An example:
#./perf record -f -e irq:irq_handler_entry:irq==18:record
or
#./perf record -f -e irq:irq_handler_entry:irq==18 -R
^C
# ./perf trace
version = 0.5
perf-4303 ... irq_handler_entry: irq=18 handler=eth0
init-0 ... irq_handler_entry: irq=18 handler=eth0
init-0 ... irq_handler_entry: irq=18 handler=eth0
init-0 ... irq_handler_entry: irq=18 handler=eth0
init-0 ... irq_handler_entry: irq=18 handler=eth0
