+# Basic idea stolen from here
+# https://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/amd-linux/918649-underclocking-undervolting-the-rx-470-with-amdgpu-pro-success
+#
+# After this I came to my own downclock idea.
+# It working with a little mess in pp_dpm_sclk output,
+# but unfortunately it seems that compiling downclock ratio
+# gives much better power saving.
+#
+# This tool modify amd gpu kernel module.
+# It allows you to undervolt and underclock your AMD RXxx GPUs under linux with amdgpu latest driver.
+#
+# COMPATIBILE with 17.20.* 17.30.* and 17.40.* amdgpu drivers
+# 17.40.* drivers require HWE kernel for Ubuntu 16.04
+#
+# BE CAREFULL!
+# I DO NOT FULLY UDERSTAND HOW DOES IT WORK AND WFT I'M DOING
