[Xen-users] Problem with debug symbols on xen kernel in xenoprofile
Hi, I have a strange problem when trying profilling domU (dom0 and domU on Debian 4.0). I use vmlinuz-2.6.18-6-xen-amd64 and for debug symbols vmlinux-2.6.18-6-xen-amd64. I installed oprofile with xen patch (http://www.xen.org/files/summit_3/xenoprof_tutorial.pdf). I get debug symbols from kernel, but don''t get debug symbols from xen kernel witch is xen-3.2-1-amd64.gz and uncompressed xen-3.2-1-amd64-syms. I get uncompressed xen kernel when I take uncompressed xen kernel from ./xen-3-3.2.1/debian/build/build-hypervisor_amd64_amd64/xen/xen-syms. I have no idea what can i do more. Compressed and uncompressed kernel are the same, compressed and uncompressed xen kernel ar also the same, but still I get no debug symbols when oprofilling: warning: /ext3 could not be found. warning: /ipv6 could not be found. warning: /jbd could not be found. warning: /oprofile could not be found. warning: /reiserfs could not be found. warning: /xen-unknown could not be found. 942547 23.6077 xen-unknown (no symbols) 104076 2.6068 libstdc++.so.6.0.8 (no symbols) 97680 2.4466 bash (no symbols) 27199 0.6812 syslog-ng (no symbols) 25012 0.6265 spread (no symbols) 18279 0.4578 libndbclient.so.4.0.0 (no symbols) 17654 0.4422 oprofile (no symbols) 11101 0.2780 reiserfs (no symbols) 5558 0.1392 libnetsnmp.so.9.0.1 (no symbols) 4006 0.1003 libcrypto.so.0.9.8 (no symbols) 2971 0.0744 libboost_thread-gcc41-mt-1_34_1.so.1.34.1 (no symbols) 2824 0.0707 libspread.so.2.0 (no symbols) 2273 0.0569 sed (no symbols) 2156 0.0540 php5 (no symbols) 2137 0.0535 mawk (no symbols) 1971 0.0494 ext3 (no symbols) 1759 0.0441 libdb-4.3.so (no symbols) 1617 0.0405 libodbc.so.1.0.0 (no symbols) 1446 0.0362 libz.so.1.2.3 (no symbols) 1341 0.0336 jbd (no symbols) 1306 0.0327 grep (no symbols) 1184 0.0297 libnetsnmpagent.so.9.0.1 (no symbols) 1118 0.0280 libmysqlclient_r.so.15.0.0 (no symbols) 1047 0.0262 monit (no symbols) 1020 0.0255 libbfd-2.17.so (no symbols) 719 0.0180 libncurses.so.5.5 (no symbols) ...
