Please correct me if I'm wrong about anything. When a perf_event is attached to a BPF program and the BPF program is going to do processing and then output what is the significant of wakeup_events or wakeup_watermark for the original perf_event?
To me it seem like it BPF program will always run, but in the absence of mmap buffer in original perf_event does it matter? Then also, what should I set my BPF_OUTPUT wakeup to? Should I set to large number? How can I get notified in my BPF OUTPUT (not the original perf) after every 5 seconds? Is that possible? -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
