From 03ecec9ed2099f6e2b62994b33dc948dc731e7b8 Mon Sep 17 00:00:00 2001 From: Kevin Rogovin Date: Mon, 27 Aug 2018 09:54:24 +0300 Subject: [PATCH] i965: Add INTEL_fragment_shader_ordering support. Adds suppport for INTEL_fragment_shader_ordering. We achieve the fragment ordering by using the same instruction as for beginInvocationInterlockARB() which is by issuing a memory fence via sendc.
