Running /usr/share/bcc/tools/runqlat 1 5 gives following error:-
libbpf: failed to find valid kernel BTF
/virtual/main.c:92:15: error: no member named 'state' in 'struct task_struct'
if (prev->state == TASK_RUNNING) {
~~~~ ^
1 error generated.
It is due to the modification of state to __state in latest kernels.
The following commit addressed the issue which checks whether the struct
"task_struct" has __state or state
https://github.com/chenhengqi/bcc/commit/d3cf5dcecfaeb6d8d346e2228626a7dbe506ad38
The above patch requires enabling CONFIG_DEBUG_INFO_BTF in the kernel
and requires pahole.
