Create a fake root directory for /proc/{version,modules,kallsyms} in
/tmp for testing. The kallsyms has a bad symbol in the module and it
causes the main map splitted. The test ensures it only has two maps -
kernel and the module and it finds the initial map after the module
without creating the split maps like [kernel].0 and so on.
$ perf test -vv "split kallsyms"
69: split kallsyms:
--- start ---
test child forked, pid 1016196
try to create fake root directory
create kernel maps from the fake root directory
maps__set_modules_path_dir: cannot open /tmp/perf-test.Zrv6Sy/lib/modules/X.Y.Z dir
Problems setting modules path maps, continuing anyway...
Failed to open /tmp/perf-test.Zrv6Sy/proc/kcore. Note /proc/kcore requires CAP_SYS_RAWIO capability to access.
Using /tmp/perf-test.Zrv6Sy/proc/kallsyms for symbols
kernel map loaded - check symbol and map
