--- Comment #5 from Marco Leise <Marco.Leise at gmx dot de> --- I use this for callgraphs: operf --vmlinux /usr/src/linux/vmlinux --callgraph ./app_to_be_profiled opreport -c%g -t=0.1% -p=/lib/modules/`uname -r`/kernel/,/lib/modules/`uname -r`/video/ And this for detailed samples: operf --vmlinux /usr/src/linux/vmlinux ./app_to_be_profiled opreport -gd%rl -t=1% -p=/lib/modules/`uname -r`/kernel/,/lib/modules/`uname -r`/video/ The app needs no instrumentation other than - of course - debug information and should dynamically link with libc. (OProfile also displays time spent in the kernel, so I added the path to the uncompressed vmlinux and modules.) Hope that helps! -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
