From fddcc67f5cb41f70d1d11827eb9190a5caec13c5 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 14 Dec 2012 10:47:46 -0700 Subject: [PATCH] softpipe: fix up FS variant unbinding / deletion The old call to tgsi_exec_machine_bind_shader() in softpipe_delete_fs_state() was never called since the shader's original tokens are never passed to the tgsi interpreter (only shader _variant_ tokens are). Now, unbind the variant's tokens from the tgsi interpreter when we free the variant. This doesn't fix any known bugs but it's the right thing to do. Note: This is a candidate for the stable branches. --- src/gallium/drivers/softpipe/sp_fs_exec.c | 7 ++++++- src/gallium/drivers/softpipe/sp_state.h | 3 ++- src/gallium/drivers/softpipe/sp_state_shader.c | 10 +--------- 3 files changed, 9 insertions(+), 11 deletions(-) diff --git a/src/gallium/drivers/softpipe/sp_fs_exec.c b/src/gallium/drivers/softpipe/sp_fs_exec.c index f5344924a1d..3793d9b3613 100644 --- a/src/gallium/drivers/softpipe/sp_fs_exec.c +++ b/src/gallium/drivers/softpipe/sp_fs_exec.c @@ -177,8 +177,13 @@ exec_run( const struct sp_fragment_shader_variant *var, static void -exec_delete( struct sp_fragment_shader_variant *var ) +exec_delete(struct sp_fragment_shader_variant *var, + struct tgsi_exec_machine *machine) { + if (machine->Tokens == var->tokens) { + tgsi_exec_machine_bind_shader(machine, NULL, 0, NULL); + } + FREE( (void *) var->tokens ); FREE(var); } diff --git a/src/gallium/drivers/softpipe/sp_state.h b/src/gallium/drivers/softpipe/sp_state.h index eb85b0689ea..fa8654fe976 100644 --- a/src/gallium/drivers/softpipe/sp_state.h +++ b/src/gallium/drivers/softpipe/sp_state.h @@ -88,7 +88,8 @@ struct sp_fragment_shader_variant struct quad_header *quad); /* Deletes this instance of the object */ - void (*delete)(struct sp_fragment_shader_variant *shader); + void (*delete)(struct sp_fragment_shader_variant *shader, + struct tgsi_exec_machine *machine); struct sp_fragment_shader_variant *next; }; diff --git a/src/gallium/drivers/softpipe/sp_state_shader.c b/src/gallium/drivers/softpipe/sp_state_shader.c index 1e64431344b..40d32a4dfb0 100644 --- a/src/gallium/drivers/softpipe/sp_state_shader.c +++ b/src/gallium/drivers/softpipe/sp_state_shader.c @@ -38,7 +38,6 @@ #include "draw/draw_vs.h" #include "draw/draw_gs.h" #include "tgsi/tgsi_dump.h" -#include "tgsi/tgsi_exec.h" #include "tgsi/tgsi_scan.h" #include "tgsi/tgsi_parse.h" @@ -182,13 +181,6 @@ softpipe_delete_fs_state(struct pipe_context *pipe, void *fs) assert(fs != softpipe->fs); - if (softpipe->fs_machine->Tokens == state->shader.tokens) { - /* unbind the shader from the tgsi executor if we're - * deleting it. - */ - tgsi_exec_machine_bind_shader(softpipe->fs_machine, NULL, 0, NULL); - } - /* delete variants */ for (var = state->variants; var; var = next_var) { next_var = var->next; @@ -200,7 +192,7 @@ softpipe_delete_fs_state(struct pipe_context *pipe, void *fs) draw_delete_fragment_shader(softpipe->draw, var->draw_shader); #endif - var->delete(var); + var->delete(var, softpipe->fs_machine); } draw_delete_fragment_shader(softpipe->draw, state->draw_shader); -- 2.30.2
