perf archive: Add helper script to package files needed to do analysis
It uses 'perf buildid-list --with-hits' to create a tarball with what is needed to have in the destination machine ~/.debug hierarchy to properly decode the perf.data file specified. Here is an example where a perf.data file collected on a x86-64 machine running Fedora 12 is used and then the data is packaged, transferred and decoded on a PARISC64 machine running Debian Testing, 32-bit userspace: [root@doppio linux-2.6-tip]# uname -a Linux doppio.ghostprotocols.net 2.6.33-rc4-tip+ #3 SMP Wed Jan 13 11:58:15 BRST 2010 x86_64 x86_64 x86_64 GNU/Linux [root@doppio linux-2.6-tip]# perf archive [root@doppio linux-2.6-tip]# ls -la perf.data* -rw------- 1 root root 737696 2010-01-14 23:36 perf.data -rw-r--r-- 1 root root 8840025 2010-01-15 12:27 perf.data.tar.bz2 [root@doppio linux-2.6-tip]# scp perf.data.* parisc64:.
