##repository of my analysis on tracepoints currently in the linux kernel. how static tracepoints are add to the linux kernel? i first started by looking inside the kernel to know how tracepoint were added. ###how to add a tracepoint in the kernel to add a tracepoint, one has to use that macro [trace_event] the use of this macro is shown in the next code snippet. in this example, we can see that the event declared is the sched_switch which is a very commun event. ~sh. /* * tracepoint for task switches, performed by the scheduler: */ trace_event(sched_switch,. #1 tp_proto(struct task_struct *prev, struct task_struct *next),. #3 tp_structentry( array( char, prev_comm, task_comm_len ) field( pid_t, prev_pid ) field( int, prev_prio ) field( long, prev_state ) array( char, next_comm, task_comm_len ) field( pid_t, next_pid ) field( int, next_prio ) ),. #4 tp_fast_assign( memcpy(entry→next_comm, next→comm, task_comm_len); entry→prev_pid = prev→pid; entry→prev_prio = prev→prio; entry→prev_state = trace_sched_switch_state(prev); memcpy(entry→prev_comm, prev→comm, task_comm_len); entry→next_pid = next→pid; entry→next_prio = next→prio; ),. #5 tp_printk( "prev_comm=%s prev_pid=%d prev_prio=%d prev_state=%s%s =⇒ next_comm=%s next_pid=%d next_prio=%d", entry→prev_comm, entry→prev_pid, entry→prev_prio, entry→prev_state & (task_state_max-1) ? print_flags(entry→prev_state & (task_state_max-1), "|", { 1, "s"} , { 2, "d" }, { 4, "t" }, { 8, "t" }, { 16, "z" }, { 32, "x" }, { 64, "x" }, { 128, "w" }) : "r", entry→prev_state & task_state_max ? "+" : "", entry→next_comm, entry→next_pid, entry→next_prio) ); ~ here i will explain the five macro calls that are the arguments of this tracepoint
