26 Add specified kcore file to the cache. For the current host that is
27 /proc/kcore which requires root permissions to read. Be aware that
33 permissions for root only. kcore will not be added if there is already a
34 kcore in the cache (with the same build-id) that has the same modules at

| D | intel-pt.txt | 61 code. A fairly good kernel image is available in /proc/kcore but to get an
62 accurate image a copy of /proc/kcore needs to be made under the same conditions
63 as the data capture. A script perf-with-kcore can do that, but beware that the
64 script makes use of 'sudo' to copy /proc/kcore. If you have perf installed
