Trying to test this with 'perf trace', i.e. to shortcircuit record + analysis: [root@jouet bpf]# perf trace -a --ev bpf-output/no-inherit,name=evt/ --ev ./test_bpf_output_3.c/map:channel.event=evt/ --ev 'perf_bpf_probe:*' usleep 100000 Failed to set filter "common_pid != 23954" on event evt with 22 (Invalid argument) Can't we set tracepoint filters on these events? - Arnaldo
