From 63f8c0af4ba934f0a9eaefaed6ae411404962196 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 10 Dec 2015 01:00:54 -0800 Subject: [PATCH] intel/skylake: Add elog event for THERMTRIP The THERMTRIP status bit is in GBLRST_CAUSE instead of GEN_PMCON like the EDSv1 indicates. Read this status bit and add an elog event if THERMTRIP has fired.
