Hello, Sorry if the question is dumb but I'm a bit lost about this.
I know that ftrace exists but I think that perf can do this too: I have a userspace application which is calling a libc C function (read) which ends up doing a sys_read. For the sys_read, I'd like to see what's happening in the kernel by displaying the call graph. Can perf do that ? If so, would it be possible to point me out the perf command to use ?
