Power limit notification feature is published in Intel 64 and IA-32 Architectures SDMV Vol 3A 14.5.6 Power Limit Notification. It is implemented first on Intel Sandy Bridge platform. The patch handles notification interrupt. Interrupt handler dumps power limit information in log_buf, logs the event in mce log, and increases the event counters (core_power_limit and package_power_limit). Upper level applications could use the data to detect system health or diagnose functionality/performance issues. In the future, the event could be handled in a more fancy way.
