WARNING: Kernel address maps (/proc/{kallsyms,modules}) are restricted,

Samples in kernel functions may not be resolved if a suitable vmlinux
file is not found in the buildid cache or in the vmlinux path.

Samples in kernel modules won't be resolved at all.

If some relocation was applied (e.g. kexec) symbols may be misresolved
even with a suitable vmlinux or kallsyms file.

Warning:
Kernel address maps (/proc/{kallsyms,modules}) were restricted.

Check /proc/sys/kernel/kptr_restrict before running 'perf record'.

As no suitable kallsyms nor vmlinux was found, kernel samples
can't be resolved.

Samples in kernel modules can't be resolved as well.
