-/**
- * ps3_sys_manager - PS3 system manager driver.
- *
- * The system manager provides an asynchronous system event notification
- * mechanism for reporting events like thermal alert and button presses to
- * guests. It also provides support to control system shutdown and startup.
- *
- * The actual system manager is implemented as an application running in the
- * system policy module in lpar_1. Guests communicate with the system manager
- * through port 2 of the vuart using a simple packet message protocol.
- * Messages are comprised of a fixed field header followed by a message
- * specific payload.
