From aa3113ae20e42b5c519936a5dc565275b1ae3ab2 Mon Sep 17 00:00:00 2001 From: Henri Verbeet Date: Mon, 15 Nov 2010 22:18:12 +0100 Subject: [PATCH] r600g: Evergreen has two extra frac_bits for the sampler LOD state. The (piglit) mipmap_limits test shows the issue very clearly. --- src/gallium/drivers/r600/evergreen_state.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/gallium/drivers/r600/evergreen_state.c b/src/gallium/drivers/r600/evergreen_state.c index 4725b5e75e2..208959dbaac 100644 --- a/src/gallium/drivers/r600/evergreen_state.c +++ b/src/gallium/drivers/r600/evergreen_state.c @@ -323,11 +323,11 @@ static void *evergreen_create_sampler_state(struct pipe_context *ctx, S_03C000_BORDER_COLOR_TYPE(uc.ui ?
