Reading samples without invoking kernel-space code should be much faster. Thanks @deater for the info!

Research direction
The issue names no file, test, or entry point. Start by locating the Libpfm sample-reading path and understanding where kernel-space code is invoked; then review how rdpmc() could replace that path. Done means samples are read through the user-space function without kernel-space calls, with the expected behavior preserved.
