Add the flags EVENT_FL_NOHANDLE and EVENT_FL_PRINTRAW to the event flags
to have the event either ignore the register handler or to ignore the
handler and also print the raw format respectively.
This allows a tool to force a raw format or non handle for

If setup_browser() called earlier than option parsing, the actual error
message can be discarded during the terminal reset. So move it after
setup_sorting() checks whether the sort keys are valid.

Current option parser outputs whole option help string when it failed to
parse an option. However this is not good for user if the command has
many option, she might feel hard which one is related easily.
Fix it by just showing the help message of the

There is a debug print (at verbose level 2) for each call to
perf_event_open. Add another debug print if the call fails, and print
the error number.

Instead of cropping off the '' and '\n' from a printk format every
time it is referenced, do it when it's added. This makes it easier to
reference a printk_map and should speed things up a little.

Add the pevent_print_func_field() that will look up a field that is
expected to be a function pointer, and it will print the function name
and offset of the address given by the field.

Always use perf_evsel__set_sample_bit() rather than just setting the

The -s (--sort) option was processed after normal option parsing so that
it cannot call the parse_options_usage() automatically. Currently it
calls usage_with_options() which shows entire help messages for event
option. Fix it by showing just -s options.

The trace_bprintk() in the kernel looks like:

If the format string of TP_printk() contains a %s, and the argument is
not a string, check if the argument is a pointer that might match the
printk_formats that were stored.
