Add a new option "--filter <filter_str>" to perf record, and
it should be right after "-e trace_point":
#./perf record -R -f -e irq:irq_handler_entry --filter irq==18
^C
# ./perf trace
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
See Documentation/trace/events.txt for the syntax of filter
expressions.
