-/*
- * Debug Store (DS) support
- *
- * This provides a low-level interface to the hardware's Debug Store
- * feature that is used for last branch recording (LBR) and
- * precise-event based sampling (PEBS).
- *
- * Different architectures use a different DS layout/pointer size.
- * The below functions therefore work on a void*.
- *
- *
- * Since there is no user for PEBS, yet, only LBR (or branch
- * trace store, BTS) is supported.
