^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) 	ptwrite, power) at the beginning. This is useful to ignore initialization code.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) 	will not be reported. Each flag must be preceded by either '+' or '-'.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) 	The flags are:

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58) 	If supported, the 'd' option may be followed by flags which affect what
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59) 	debug messages will or will not be logged. Each flag must be preceded
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 60) 	by either '+' or '-'. The flags are:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 61) 		a	all perf events
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 62)
