Resolution of Symbol Names for Linux-Loadable Kernel Modules

To resolve symbol information for Linux kernel modules,
Intel® VTune™
Profiler
 uses content in the
/sys/module/<module-name>/sections/
 directory during the finalization step.
Default permissions for the
/sys/module/<module-name>/sections/
 directory may allow access only for the root user. In this case,
VTune
Profiler
 reports a warning message. Run
VTune
Profiler
 with root privileges or change permissions for all files in this directory.

Limitations

When you collect data on a remote Linux system,
VTune
Profiler
 does not read
/sys/module/<module-name>/sections/*
 for results. In this case, to resolve symbols properly:
  1. Copy the
    <module-name>/sections
     folder manually from the target system to
    ../<parent directory>/<module-name>/sections
     on the host system.
  2. Add
    <parent directory>
     to VTune search directories for binary and symbol files.
