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. --- .../drivers/i965simple/brw_wm_sampler_state.c | 38 +++++++++++----------- 1 file changed, 19 insertions(+), 19 deletions(-) (limited to 'src/gallium/drivers/i965simple') diff --git a/src/gallium/drivers/i965simple/brw_wm_sampler_state.c b/src/gallium/drivers/i965simple/brw_wm_sampler_state.c index ff5ba7e7c7a..b9eaee56ee8 100644 --- a/src/gallium/drivers/i965simple/brw_wm_sampler_state.c +++ b/src/gallium/drivers/i965simple/brw_wm_sampler_state.c @@ -136,6 +136,9 @@ static void brw_update_sampler_state( const struct pipe_sampler_state *pipe_samp case PIPE_TEX_FILTER_LINEAR: sampler->ss0.min_filter = BRW_MAPFILTER_LINEAR; break; + case PIPE_TEX_FILTER_ANISO: + sampler->ss0.min_filter = BRW_MAPFILTER_ANISOTROPIC; + break; default: break; } @@ -155,26 +158,23 @@ static void brw_update_sampler_state( const struct pipe_sampler_state *pipe_samp } /* Set Anisotropy: */ - if (pipe_sampler->max_anisotropy > 1.0) { - sampler->ss0.min_filter = BRW_MAPFILTER_ANISOTROPIC; - sampler->ss0.mag_filter = BRW_MAPFILTER_ANISOTROPIC; - - if (pipe_sampler->max_anisotropy > 2.0) { - sampler->ss3.max_aniso = MAX2((pipe_sampler->max_anisotropy - 2) / 2, - BRW_ANISORATIO_16); - } + switch (pipe_sampler->mag_img_filter) { + case PIPE_TEX_FILTER_NEAREST: + sampler->ss0.mag_filter = BRW_MAPFILTER_NEAREST; + break; + case PIPE_TEX_FILTER_LINEAR: + sampler->ss0.mag_filter = BRW_MAPFILTER_LINEAR; + break; + case PIPE_TEX_FILTER_ANISO: + sampler->ss0.mag_filter = BRW_MAPFILTER_LINEAR; + break; + default: + break; } - else { - switch (pipe_sampler->mag_img_filter) { - case PIPE_TEX_FILTER_NEAREST: - sampler->ss0.mag_filter = BRW_MAPFILTER_NEAREST; - break; - case PIPE_TEX_FILTER_LINEAR: - sampler->ss0.mag_filter = BRW_MAPFILTER_LINEAR; - break; - default: - break; - } + + if (pipe_sampler->max_anisotropy > 2.0) { + sampler->ss3.max_aniso = MAX2((pipe_sampler->max_anisotropy - 2) / 2, + BRW_ANISORATIO_16); } sampler->ss1.s_wrap_mode = translate_wrap_mode(pipe_sampler->wrap_s); -- cgit v1.2.3
