$ trace_event tests attaching BPF program to HW_CPU_CYCLES, SW_CPU_CLOCK, HW_CACHE_L1D and other events. It runs 'dd' in the background while bpf program collects user and kernel stack trace on counter overflow. User space expects to see sys_read and sys_write in the kernel stack. $ tracex6 tests reading of various perf counters from BPF program. Both tests were refactored to increase coverage and be more accurate. Signed-off-by: Teng Qin <qinteng@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.
