68 * augmented_arg: extra payload for syscall pointer arguments
70 * If perf_sample->raw_size is more than what a syscall sys_enter_FOO puts,
71 * then its the arguments contents, so that we can show more than just a
72 * pointer. This will be done initially with eBPF, the start of that is at the
73 * tools/perf/examples/bpf/augmented_syscalls.c example for the openat, but
74 * will eventually be done automagically caching the running kernel tracefs
75 * events data into an eBPF C script, that then gets compiled and its .o file
76 * cached for subsequent use. For char pointers like the ones for 'open' like
77 * syscalls its easy, for the rest we should use DWARF or better, BTF, much
80 * @size: 8 if all we need is an integer, otherwise all of the augmented arg.
81 * @int_arg: will be used for integer like pointer contents, like 'accept's 'upeer_addrlen'
82 * @value: u64 aligned, for structs, pathnames
84 struct augmented_arg {
90 struct syscall_arg_fmt;
93 * @val: value of syscall argument being formatted
94 * @len: for tracepoint dynamic arrays, if fmt->nr_entries == 0, then its not a fixed array, look at arg->len
95 * @args: All the args, use syscall_args__val(arg, nth) to access one
96 * @augmented_args: Extra data that can be collected, for instance, with eBPF for expanding the pathname for open, etc
97 * @augmented_args_size: augmented_args total payload size
98 * @thread: tid state (maps, pid, tid, etc)
99 * @trace: 'perf trace' internals: all threads, etc
100 * @parm: private area, may be an strarray, for instance
101 * @idx: syscall arg idx (is this the first?)
102 * @mask: a syscall arg may mask another arg, see syscall_arg__scnprintf_futex_op
103 * @show_string_prefix: When there is a common prefix in a string table, show it or not
