| H A D | perf-kwork.txt | 4f8ae962 Fri Jul 08 20:50:18 CDT 2022 Yang Jihong <yangjihong1@huawei.com> perf kwork: Add irq kwork record support
Record interrupt events irq:irq_handler_entry & irq_handler_exit
Test cases:
# perf kwork record -o perf_kwork.date -- sleep 1
[ perf record: Woken up 0 times to write data ]
[ perf record: Captured and wrote 0.556 MB perf_kwork.date ]
#
# perf evlist -i perf_kwork.date
irq:irq_handler_entry
irq:irq_handler_exit
dummy:HG
# Tip: use 'perf evlist --trace-fields' to show fields for tracepoint events
