Subject: [PATCH 00/12] add syscall tracepoints V3

Date: Monday, August 10, 2009 - 1:52 pm

hi,

The following is an implementation of Frederic's syscall tracer on top of
tracepoints. It adds the ability to toggle the entry/exit of each syscall
via the standard events/syscalls/syscall_blah/enable interface. The
implementation is done by adding 2 tracepoints. One on entry and one for exit.

The patchset now also addes 'perf' tool support for counting the number of
syscall events. For example, I did a simple strace of 'cat'ing' a file, and
then verified that 'perf stat' gave a similar count.

For example:

#   perf stat -e syscalls:sys_enter_brk -e syscalls:sys_exit_brk -e syscalls:sys_enter_mmap -e syscalls:sys_enter_mmap -e syscalls:sys_enter_access -e syscalls:sys_exit_access  -e syscalls:sys_enter_close -e syscalls:sys_exit_close -e syscalls:sys_enter_read -e syscalls:sys_exit_read -e syscalls:sys_enter_write -e syscalls:sys_exit_write -e syscalls:sys_enter_mprotect -e syscalls:sys_exit_mprotect -e  syscalls:sys_enter_open -e syscalls:sys_exit_open -e syscalls:sys_enter_newfstat -e syscalls:sys_exit_newfstat -e syscalls:sys_enter_exit_group -e syscalls:sys_exit_exit_group cat /tmp/foo 


 Performance counter stats for 'cat /tmp/foo':

              3  syscalls:sys_enter_brk  
              3  syscalls:sys_exit_brk   
              9  syscalls:sys_enter_mmap 
              9  syscalls:sys_enter_mmap 
              1  syscalls:sys_enter_access
              1  syscalls:sys_exit_access
              6  syscalls:sys_enter_close
              6  syscalls:sys_exit_close 
              3  syscalls:sys_enter_read 
              3  syscalls:sys_exit_read  
              1  syscalls:sys_enter_write
              1  syscalls:sys_exit_write 
              3  syscalls:sys_enter_mprotect
              3  syscalls:sys_exit_mprotect
              4  syscalls:sys_enter_open 
              4  syscalls:sys_exit_open  
              5  syscalls:sys_enter_newfstat
              5  syscalls:sys_exit_newfstat
              1  syscalls:sys_enter_exit_group
              0  syscalls:sys_exit_exit_group

thanks,

-Jason
