From 1a82d9648b3db780e58e4966924157542d148c58 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 7 May 2008 16:44:33 -0600 Subject: [PATCH] gallium: fix some render to texture bugs Before, we were sometimes rendering into a stale texture because st_finalize_texture() would discard the old texture and create a new one. Moved st_update_framebuffer atom after texture validation so that we can create a new renderbuffer surface if the texture changes. Also, split texture validation into two parts: finalize_textures and update_textures. Do finalize_textures first to avoid getting into the situtation where we're doing a pipe->surface_copy() mid-way through state validation. Some debug code still in place, but disabled... --- src/mesa/state_tracker/st_atom.c | 3 +- src/mesa/state_tracker/st_atom.h | 1 + src/mesa/state_tracker/st_atom_framebuffer.c | 60 ++++++++++++++- src/mesa/state_tracker/st_atom_shader.c | 26 ++++++- src/mesa/state_tracker/st_atom_texture.c | 80 ++++++++++++-------- src/mesa/state_tracker/st_cb_fbo.c | 34 +++++++-- src/mesa/state_tracker/st_cb_fbo.h | 3 + src/mesa/state_tracker/st_cb_readpixels.c | 2 + src/mesa/state_tracker/st_cb_texture.c | 1 + src/mesa/state_tracker/st_context.h | 3 + src/mesa/state_tracker/st_texture.c | 16 ++++ 11 files changed, 189 insertions(+), 40 deletions(-) diff --git a/src/mesa/state_tracker/st_atom.c b/src/mesa/state_tracker/st_atom.c index 18063adc79c..ecfd1179189 100644 --- a/src/mesa/state_tracker/st_atom.c +++ b/src/mesa/state_tracker/st_atom.c @@ -45,10 +45,10 @@ */ static const struct st_tracked_state *atoms[] = { - &st_update_framebuffer, &st_update_depth_stencil_alpha, &st_update_clip, + &st_finalize_textures, &st_update_shader, &st_update_rasterizer, @@ -58,6 +58,7 @@ static const struct st_tracked_state *atoms[] = &st_update_blend, &st_update_sampler, &st_update_texture, + &st_update_framebuffer, &st_update_vs_constants, &st_update_fs_constants, &st_update_pixel_transfer diff --git a/src/mesa/state_tracker/st_atom.h b/src/mesa/state_tracker/st_atom.h index c6c6eba8121..c7cffd85c8a 100644 --- a/src/mesa/state_tracker/st_atom.h +++ b/src/mesa/state_tracker/st_atom.h @@ -55,6 +55,7 @@ extern const struct st_tracked_state st_update_scissor;
