/proc/kcore which requires root permissions to read. Be aware that
running 'perf buildid-cache' as root may update root's build-id cache
not the user's. Use the -v option to see where the file is created.
Note that the copied file contains only code sections not the whole core
image. Note also that files "kallsyms" and "modules" must also be in the
same directory and are also copied. All 3 files are created with read
permissions for root only. kcore will not be added if there is already a
kcore in the cache (with the same build-id) that has the same modules at
the same addresses. Use the -v option to see if a copy of kcore is
actually made.

DESCRIPTION
-----------
@ -16,9 +17,14 @@ This command will show the events associated with the target, initially
syscalls, but other system events like pagefaults, task lifetime events,
scheduling events, etc.
Initially this is a live mode only tool, but eventually will work with
perf.data files like the other tools, allowing a detached 'record' from
analysis phases.
This is a live mode tool in addition to working with perf.data files like
the other perf tools. Files can be generated using the 'perf record' command
but the session needs to include the raw_syscalls events (-e 'raw_syscalls:*').
Alernatively, the 'perf trace record' can be used as a shortcut to
automatically include the raw_syscalls events when writing events to a file.
The following options apply to perf trace; options to perf trace record are
found in the perf record man page.
