From 6b52f813958648d7ba7ae469cac0c0a53ef1987c Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Tue, 3 Sep 2019 17:29:11 -0700 Subject: [PATCH] intel/eu: Don't set notify descriptor field of gateway barrier message. Apparently this field was removed on SKL, and according to the hardware docs for previous platforms "This field is only valid for a ForwardMsg message. It is ignored for other messages. The BarrierMsg message always increments the N0 notification counter".
