From 5cc51c08cd44e2749f4a27775cefffd4b91e0a50 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 7 Mar 2013 14:06:43 -0800 Subject: lynxpoint: Add function for checking for LP chipset Add a helper function pch_is_lp() that will return 1 if the current chipset is of the new "low power" variant used with Haswell ULT. Additionally these functions are added to SMM so it can be used there.
