Y= ou can either download the debuginfo package of the corresponding kernel which should place the vmlinux in the required place or even having the "vmlinux" with debug symbols in the same directory as where you are running perf probe shall do. Also, once this error is resolved you *might* encounter something like " Er= ror: Failed to show lines." To fix it you can install the kernel source code pac= kage or just use the -s flag to point to the source code. (Example of how I use = it): sudo perf probe -s ~/workspace/9p -a "ext4_mb_find_good_group_avg_frag_lists order" Let me know if it still doesn't work. Thanks!
