Hi all,
I recently use perf "-e raw_syscalls:sys_enter -e raw_syscalls:sys_exit" to
trace all the syscall entry and exit.
After i perf script the data, I get result like below:
perf 10258 [013] 260748.823215: sys_exit: NR 0 = 0
perf 10258 [013] 260748.823244: sys_enter: NR 59 (7fffd5b085bf,
7fffd5b0bb10, 12f7030, 3266018240, 65726f632d667265, 2811)
perf 10258 [013] 260748.823280: sys_exit: NR 59 = -2

runspec 10258 [019] 260748.824245: sys_exit: NR 9 = 140288080809984
runspec 10258 [019] 260748.824247: sys_enter: NR 3 (4, c052, 1, 2, 4,
0)
runspec 10258 [019] 260748.824249: sys_exit: NR 3 = 0
I guess that the NR # in the end of the line is defined as the systemcall id,
but i'm confused about how to match the NR id to the exact systemcall name! Is
there any systemcall table or list that I can check the system name accoring to
the NR number?
Best,
Chen
