| * augmented_arg: extra payload for syscall pointer arguments |
| |
| * If perf_sample->raw_size is more than what a syscall sys_enter_FOO puts, |
| * then its the arguments contents, so that we can show more than just a |
| * pointer. This will be done initially with eBPF, the start of that is at the |
| * tools/perf/examples/bpf/augmented_syscalls.c example for the openat, but |
| * will eventually be done automagically caching the running kernel tracefs |
| * events data into an eBPF C script, that then gets compiled and its .o file |
| * cached for subsequent use. For char pointers like the ones for 'open' like |
| * syscalls its easy, for the rest we should use DWARF or better, BTF, much |
| * more compact. |
| * |
| * @size: 8 if all we need is an integer, otherwise all of the augmented arg. |
| * @int_arg: will be used for integer like pointer contents, like 'accept's 'upeer_addrlen' |
| * @value: u64 aligned, for structs, pathnames |
