So it recommends to run perf buildid-cache to install proper vmlinux image. But running perf buildid-cache -av vmlinux as the message gives me a following error: $ perf buildid-cache -av /home/namhyung/build/kernel/vmlinux Couldn't add v: No such file or directory Since the -a option receives a parameter, 'v' should not be after the option. In addition -a option is not work for this case since the build-id cache already has a kallsyms with same build-id so it'll fail with EEXIST. Use recently added -u (--update) option for it.
