With this we can list the buildids in a perf.data file so that we can pipe them to other, distro specific tools that from the buildids can figure out separate packages (foo-debuginfo) where we can find the matching symtabs so that perf report can do its job. E.g: [acme@doppio linux-2.6-tip]$ perf buildid-list | head -5 8e08b117e5458ad3f85da16d42d0fc5cd21c5869 520c2387a587cc5acfcf881e27dba1caaeab4b1f ec8dd400904ddfcac8b1c343263a790f977159dc 7caedbca5a6d8ab39a7fe44bd28c07d3e14a3f3f 379bb828fd08859dbea73279f04abefabc95a6a3 [acme@doppio linux-2.6-tip]$ perf buildid-list -v | head -5 8e08b117e5458ad3f85da16d42d0fc5cd21c5869 /sbin/init 520c2387a587cc5acfcf881e27dba1caaeab4b1f /lib64/ld-2.10.1.so ec8dd400904ddfcac8b1c343263a790f977159dc /lib64/libc-2.10.1.so 7caedbca5a6d8ab39a7fe44bd28c07d3e14a3f3f /sbin/udevd 379bb828fd08859dbea73279f04abefabc95a6a3 /lib64/libdl-2.10.1.so [acme@doppio linux-2.6-tip]$ Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> LKML-Reference: <1258396365-29217-5-git-send-email-acme@infradead.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
