Lowering the freq to 4kHz gets me to where I think you was at this point: [root@zoo ~]# perf test -v 21 21: Test object code reading : --- start --- Looking at the vmlinux_path (6 entries long) symsrc__init: cannot get elf header. Using /lib/modules/3.11.0-rc2+/build/vmlinux for symbols Parsing event 'cycles' Reading object code for memory address: 0xffffffff8101ce7d File is: /lib/modules/3.11.0-rc2+/build/vmlinux On file address is: 0xffffffff8101ce7d dso__data_read_offset failed ---- end ---- Test object code reading: FAILED! [root@zoo ~]# I.e. we need the follow on patches to fix this issue, right? I'll merge my changes with your first patch and continue from there. - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
