hi,
some of the events in ftrace have dynamic array fields. Like :
field:__data_loc char[] arg1; offset:24; size:4; signed:1;
If i am sampling this particular event using perf_event_open(), how do
i read this field
i tried:
#define get_str(field) (char *)get_dynamic_array(field)
#define get_dynamic_array(field) \
((void *)data + (data->__data_loc_##field & 0xffff))
as done in include/trace/ftrace,h
But it gives garble data.
TID:28578 PID:28578 TIME:258203626722378 CPU:4 Filename: ^\~@b�^O~H��^H�^?
Will appreciate any help.
Thanks
-sahil
