From 58a57ea7d6cd2313989ee9c9759d4270b0bd675d Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Mon, 20 Mar 2017 15:25:21 -0700 Subject: [PATCH] i965/sf: make brw_sf_prog_key::interp_mode an array Having it be a pointer means that we end up caching clip programs based on a pointer to wm_prog_data rather than the actual interpolation modes. We've been caching one clip program per FS ever since 91d61fbf7cb61a44a where Timothy rewrote brw_setup_vue_interpolation().
