* 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
