From 724adec33c2491f26f739f285ddca25fca226e48 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Mon, 13 May 2019 13:58:52 -0400 Subject: [PATCH] thermal/x86_pkg_temp_thermal: Support multi-die/package Package temperature sensors are actually implemented in hardware per-die. Thus, the new multi-die/package systems sport mulitple package thermal zones for each package. Update the x86_pkg_temp_thermal to be "multi-die-aware", so it can expose multiple zones per package, instead of just one.
