From 8987152ac16153999c972f08b6864c5e5ec9bdfb Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 2 May 2019 15:42:10 -0700 Subject: [PATCH] iris: Resolve textures used by the program, not merely bound textures st/mesa's PBO upload path binds a vertex shader that doesn't use any textures, but leaves the existing sampler views bound in place. This was tricking us into thinking the PBO destination might be bound for texturing in some cases. In Civilization VI, this fixes a false self- dependency issue that was preventing CCS_E compression on upload. Fixing this slightly improves frame times. --- src/gallium/drivers/iris/iris_resolve.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/src/gallium/drivers/iris/iris_resolve.c b/src/gallium/drivers/iris/iris_resolve.c index db82afb3530..ac2676cce0d 100644 --- a/src/gallium/drivers/iris/iris_resolve.c +++ b/src/gallium/drivers/iris/iris_resolve.c @@ -83,10 +83,11 @@ static void resolve_sampler_views(struct iris_context *ice, struct iris_batch *batch, struct iris_shader_state *shs, + const struct shader_info *info, bool *draw_aux_buffer_disabled, bool consider_framebuffer) { - uint32_t views = shs->bound_sampler_views; + uint32_t views = info ?
