From 4fac9500100273424450b5687c4e04dfd066d08e Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 9 Dec 2015 21:42:21 -0800 Subject: [PATCH] i965: Force VS -> TCS varyings to use the SSO VUE map layout. The compact VUE map only works when varying packing is in use. Unfortunately, varying packing is disabled for TCS inputs. This is needed to fix Piglit's tcs-input-read-array-interface test. v2: Make lines fit in 80 columns (caught by Jordan Justen).
