From 98ae83d5cc73b61826823c915b5c59746c2e85c7 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Wed, 12 Mar 2008 10:39:25 +0000 Subject: gallium: Add TEX_FILTER_ANISO img filter Hardware almost universally expects us to set a special filtering mode when anisotropic filtering is enabled, as opposed to varying a max-aniso values. Do this once in the state tracker & simplify the driver code. --- src/gallium/drivers/i915simple/i915_state.c | 19 ++++++++----------- 1 file changed, 8 insertions(+), 11 deletions(-) (limited to 'src/gallium/drivers/i915simple') diff --git a/src/gallium/drivers/i915simple/i915_state.c b/src/gallium/drivers/i915simple/i915_state.c index d9ab483bfca..57b195ea8d7 100644 --- a/src/gallium/drivers/i915simple/i915_state.c +++ b/src/gallium/drivers/i915simple/i915_state.c @@ -71,6 +71,8 @@ static unsigned translate_img_filter( unsigned filter ) return FILTER_NEAREST; case PIPE_TEX_FILTER_LINEAR: return FILTER_LINEAR; + case PIPE_TEX_FILTER_ANISO: + return FILTER_ANISOTROPIC; default: assert(0); return FILTER_NEAREST; @@ -84,7 +86,7 @@ static unsigned translate_mip_filter( unsigned filter ) return MIPFILTER_NONE; case PIPE_TEX_MIPFILTER_NEAREST: return MIPFILTER_NEAREST; - case PIPE_TEX_FILTER_LINEAR: + case PIPE_TEX_MIPFILTER_LINEAR: return MIPFILTER_LINEAR; default: assert(0); @@ -211,16 +213,11 @@ i915_create_sampler_state(struct pipe_context *pipe, cso->templ = sampler; mipFilt = translate_mip_filter(sampler->min_mip_filter); - if (sampler->max_anisotropy > 1.0) { - minFilt = FILTER_ANISOTROPIC; - magFilt = FILTER_ANISOTROPIC; - if (sampler->max_anisotropy > 2.0) { - cso->state[0] |= SS2_MAX_ANISO_4; - } - } - else { - minFilt = translate_img_filter( sampler->min_img_filter ); - magFilt = translate_img_filter( sampler->mag_img_filter ); + minFilt = translate_img_filter( sampler->min_img_filter ); + magFilt = translate_img_filter( sampler->mag_img_filter ); + + if (sampler->max_anisotropy > 2.0) { + cso->state[0] |= SS2_MAX_ANISO_4; } { -- cgit v1.2.3
