From 8abee9566b7e8eecf566c4daf6be062a27369890 Mon Sep 17 00:00:00 2001 From: Naveen Krishna Chatradhi Date: Tue, 19 May 2020 21:20:09 +0530 Subject: hwmon: Add amd_energy driver to report energy counters This patch adds hwmon based amd_energy driver support for family 17h processors from AMD. The driver provides following interface to the userspace 1. Reports the per core consumption * file: "energy%d_input", label: "Ecore%03d" 2. Reports per socket energy consumption * file: "energy%d_input", label: "Esocket%d" 3. To, increase the wrap around time of the socket energy counters, a 64bit accumultor is implemented. 4. Reports scaled energy value in Joules.
