From 211bb97c67ce704fb40abb6dd9971790652237e3 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Wed, 14 Mar 2018 09:11:20 -0700 Subject: mb/google/eve: Update DPTF parameters 1) Set the critical temperature threshold to 100C to match changes on other boards. This is intended to reduce DPTF-initiated thermal shutdowns before it has had a chance to react. 2) Reduce the CPU passive threshold sample rate from 5 seconds to 1 second so DPTF will react faster to rapid temperature increases.
