    perf bpf: Add bpf_map dumper · d19f8564
    Arnaldo Carvalho de Melo authored
    At some point I'll suggest moving this to libbpf, for now I'll
    experiment with ways to dump BPF maps set by events in 'perf trace',
    starting with a very basic dumper for the current very limited needs
    of the augmented_raw_syscalls code: dumping booleans.
    
    Having functions that apply to the map keys and values and do table
    lookup in things like syscall id to string tables should come next.
