| 2024-08-21 | perf bpf: Remove redundant check that map is NULL | Yang Ruibin | 1 | -3/+0 | |
| The check that map is NULL is already done in the bpf_map__fd(map) and returns an errno, which does not run further checks. In addition, even if the check for map is run, the return is a pointer, which is not consistent with the err_number returned by bpf_map__fd(map).

| 2019-02-19 | perf bpf: Add bpf_map dumper | Arnaldo Carvalho de Melo | 1 | -0/+72 | |
| 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.
