From 4da1cdf78fa3b954840650fa46cf72da5daf149f Mon Sep 17 00:00:00 2001 From: Brian Date: Tue, 12 Feb 2008 14:53:25 -0700 Subject: gallium: clean-up, simplification of mipmapped textures Remove pipe_texture->first_level (always implicitly zero). This means there's never any unused mipmap levels at the top. In the state tracker, we no longer re-layout mipmapped textures if the MinLod/MaxLod texture parameters change. It's up to the driver to obey the pipe_sampler->min/max_lod clamps. --- src/mesa/pipe/i915simple/i915_state.c | 7 ++++++ src/mesa/pipe/i915simple/i915_state_sampler.c | 2 +- src/mesa/pipe/i915simple/i915_texture.c | 30 ++++++++++++------------- src/mesa/pipe/i965simple/brw_tex_layout.c | 8 +++---- src/mesa/pipe/i965simple/brw_wm_surface_state.c | 2 +- src/mesa/pipe/p_state.h | 14 ++++-------- src/mesa/pipe/softpipe/sp_state_sampler.c | 4 ++++ src/mesa/pipe/softpipe/sp_tex_sample.c | 18 +++++---------- src/mesa/pipe/softpipe/sp_texture.c | 4 +++- 9 files changed, 44 insertions(+), 45 deletions(-) (limited to 'src/mesa/pipe') diff --git a/src/mesa/pipe/i915simple/i915_state.c b/src/mesa/pipe/i915simple/i915_state.c index 950ea52d601..abd5571b885 100644 --- a/src/mesa/pipe/i915simple/i915_state.c +++ b/src/mesa/pipe/i915simple/i915_state.c @@ -250,6 +250,13 @@ i915_create_sampler_state(struct pipe_context *pipe, if (sampler->normalized_coords) cso->state[1] |= SS3_NORMALIZED_COORDS; + if (0) /* XXX not tested yet */ + { + int minlod = (int) (16.0 * sampler->min_lod); + minlod = CLAMP(minlod, 0, 16 * 11); + cso->state[1] |= (minlod << SS3_MIN_LOD_SHIFT); + } + { ubyte r = float_to_ubyte(sampler->border_color[0]); ubyte g = float_to_ubyte(sampler->border_color[1]); diff --git a/src/mesa/pipe/i915simple/i915_state_sampler.c b/src/mesa/pipe/i915simple/i915_state_sampler.c index 0dbbc5241d5..9c1a5bbbd65 100644 --- a/src/mesa/pipe/i915simple/i915_state_sampler.c +++ b/src/mesa/pipe/i915simple/i915_state_sampler.c @@ -185,7 +185,7 @@ i915_update_texture(struct i915_context *i915, uint unit, const struct pipe_texture *pt = &tex->base; uint format, pitch; const uint width = pt->width[0], height = pt->height[0], depth = pt->depth[0]; - const uint num_levels = pt->last_level - pt->first_level; + const uint num_levels = pt->last_level; assert(tex); assert(width); diff --git a/src/mesa/pipe/i915simple/i915_texture.c b/src/mesa/pipe/i915simple/i915_texture.c index 6faeab134ab..6d37ae3d747 100644 --- a/src/mesa/pipe/i915simple/i915_texture.c +++ b/src/mesa/pipe/i915simple/i915_texture.c @@ -118,11 +118,11 @@ i945_miptree_layout_2d( struct i915_texture *tex ) tex->pitch = pt->width[0]; /* May need to adjust pitch to accomodate the placement of - * the 2nd mipmap.
