405 | * tracepoint_string - register constant persistent string to trace system | |
406 | * @str - a constant persistent string that will be referenced in tracepoints | |
407 | * | |
408 | * If constant strings are being used in tracepoints, it is faster and | |
409 | * more efficient to just save the pointer to the string and reference | |
410 | * that with a printf "%s" instead of saving the string in the ring buffer | |
411 | * and wasting space and time. | |
412 | * | |
413 | * The problem with the above approach is that userspace tools that read | |
414 | * the binary output of the trace buffers do not have access to the string. | |
415 | * Instead they just show the address of the string which is not very | |
416 | * useful to users. | |
417 | * | |
418 | * With tracepoint_string(), the string will be registered to the tracing | |
419 | * system and exported to userspace via the debugfs/tracing/printk_formats | |
420 | * file that maps the string address to the string text. This way userspace | |
421 | * tools that read the binary buffers have a way to map the pointers to | |
422 | * the ASCII strings they represent. | |
423 | * | |
424 | * The @str used must be a constant string and persistent as it would not | |
425 | * make sense to show a string that no longer exists. But it is still fine | |
426 | * to be used with modules, because when modules are unloaded, if they | |
427 | * had tracepoints, the ring buffers are cleared too. As long as the string | |
428 | * does not change during the life of the module, it is fine to use | |
429 | * tracepoint_string() within a module. | |
