From 1a859ecf4a4728cb321b1f68d51491cd285a3c03 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Tue, 9 Feb 2010 21:23:27 +0100 Subject: gallium: don't put stencil ref value in pipe_depth_stencil_alpha_state This will make driver's life a bit harder, however it makes sense that stencil reference value is not part of the pipe_depth_stencil_alpha_state, because it often (there are some algorithms which require this) changes more frequently than the rest of the dsa state. This is also encouraged by some graphic APIs. Treat it similar to pipe_blend_color. --- src/gallium/auxiliary/util/u_blitter.c | 75 +++++++++++++--------------------- 1 file changed, 28 insertions(+), 47 deletions(-) (limited to 'src/gallium/auxiliary/util') diff --git a/src/gallium/auxiliary/util/u_blitter.c b/src/gallium/auxiliary/util/u_blitter.c index f3b4491d175..0504538258d 100644 --- a/src/gallium/auxiliary/util/u_blitter.c +++ b/src/gallium/auxiliary/util/u_blitter.c @@ -60,13 +60,12 @@ struct blitter_context_priv float vertices[4][2][4]; /**< {pos, color} or {pos, texcoord} */ /* Templates for various state objects. */ - struct pipe_depth_stencil_alpha_state template_dsa; struct pipe_sampler_state template_sampler_state; /* Constant state objects. */ /* Vertex shaders. */ void *vs_col; /**< Vertex shader which passes {pos, color} to the output */ - void *vs_tex; /**blend_write_color = pipe->create_blend_state(pipe, &blend); /* depth stencil alpha state objects */ - dsa = &ctx->template_dsa; ctx->dsa_keep_depth_stencil = - pipe->create_depth_stencil_alpha_state(pipe, dsa); + pipe->create_depth_stencil_alpha_state(pipe, &dsa); - dsa->depth.enabled = 1; - dsa->depth.writemask = 1; - dsa->depth.func = PIPE_FUNC_ALWAYS; + dsa.depth.enabled = 1; + dsa.depth.writemask = 1; + dsa.depth.func = PIPE_FUNC_ALWAYS; ctx->dsa_write_depth_keep_stencil = - pipe->create_depth_stencil_alpha_state(pipe, dsa); - - dsa->stencil[0].enabled = 1; - dsa->stencil[0].func = PIPE_FUNC_ALWAYS; - dsa->stencil[0].fail_op = PIPE_STENCIL_OP_REPLACE; - dsa->stencil[0].zpass_op = PIPE_STENCIL_OP_REPLACE; - dsa->stencil[0].zfail_op = PIPE_STENCIL_OP_REPLACE; - dsa->stencil[0].valuemask = 0xff; - dsa->stencil[0].writemask = 0xff; + pipe->create_depth_stencil_alpha_state(pipe, &dsa); + + dsa.stencil[0].enabled = 1; + dsa.stencil[0].func = PIPE_FUNC_ALWAYS; + dsa.stencil[0].fail_op = PIPE_STENCIL_OP_REPLACE; + dsa.stencil[0].zpass_op = PIPE_STENCIL_OP_REPLACE; + dsa.stencil[0].zfail_op = PIPE_STENCIL_OP_REPLACE; + dsa.stencil[0].valuemask = 0xff; + dsa.stencil[0].writemask = 0xff; + ctx->dsa_write_depth_stencil = + pipe->create_depth_stencil_alpha_state(pipe, &dsa); /* The DSA state objects which write depth and stencil are created * on-demand. */ @@ -210,12 +210,8 @@ void util_blitter_destroy(struct blitter_context *blitter) pipe->delete_depth_stencil_alpha_state(pipe, ctx->dsa_keep_depth_stencil); pipe->delete_depth_stencil_alpha_state(pipe, ctx->dsa_write_depth_keep_stencil); - - for (i = 0; i < 0xff; i++) - if (ctx->dsa_write_depth_stencil[i]) - pipe->delete_depth_stencil_alpha_state(pipe, - ctx->dsa_write_depth_stencil[i]); - + pipe->delete_depth_stencil_alpha_state(pipe, ctx->dsa_write_depth_stencil); + pipe->delete_rasterizer_state(pipe, ctx->rs_state); pipe->delete_vs_state(pipe, ctx->vs_col); pipe->delete_vs_state(pipe, ctx->vs_tex); @@ -412,26 +408,6 @@ static void blitter_draw_quad(struct blitter_context_priv *ctx) 2); /* attribs/vert */ } -static INLINE -void *blitter_get_state_write_depth_stencil( - struct blitter_context_priv *ctx, - unsigned stencil) -{ - struct pipe_context *pipe = ctx->pipe; - - stencil &= 0xff; - - /* Create the DSA state on-demand. */ - if (!ctx->dsa_write_depth_stencil[stencil]) { - ctx->template_dsa.stencil[0].ref_value = stencil; - - ctx->dsa_write_depth_stencil[stencil] = - pipe->create_depth_stencil_alpha_state(pipe, &ctx->template_dsa); - } - - return ctx->dsa_write_depth_stencil[stencil]; -} - static INLINE void **blitter_get_sampler_state(struct blitter_context_priv *ctx, int miplevel) @@ -559,9 +535,13 @@ void util_blitter_clear(struct blitter_context *blitter, else pipe->bind_blend_state(pipe, ctx->blend_keep_color); - if (clear_buffers & PIPE_CLEAR_DEPTHSTENCIL) - pipe->bind_depth_stencil_alpha_state(pipe, - blitter_get_state_write_depth_stencil(ctx, stencil)); + if (clear_buffers & PIPE_CLEAR_DEPTHSTENCIL) { + struct pipe_stencil_ref sr; + memset (&sr, 0, sizeof(sr)); + sr.ref_value[0] = stencil & 0xff; + pipe->bind_depth_stencil_alpha_state(pipe, ctx->dsa_write_depth_stencil); + pipe->set_stencil_ref(pipe, &sr); + } else pipe->bind_depth_stencil_alpha_state(pipe, ctx->dsa_keep_depth_stencil); @@ -573,6 +553,7 @@ void util_blitter_clear(struct blitter_context *blitter, blitter_set_rectangle(ctx, 0, 0, width, height, depth); blitter_draw_quad(ctx); blitter_restore_CSOs(ctx); + /* XXX driver's responsibility to restore stencil refs? */ } static boolean -- cgit v1.2.3
