From c262c4a2ff1a19d0136771767ba63f04cf3b83e3 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 23 Sep 2010 14:18:22 +1000 Subject: [PATCH] u_blitter: add a custom blitter call passing a dsa cso reimplement the flush stage added for r300 to allow a custom DSA stage to be used in the pipeline, this allows for r600 hw DB->CB flushes. --- src/gallium/auxiliary/util/u_blitter.c | 45 ++++++++++++++++++-------- src/gallium/auxiliary/util/u_blitter.h | 6 ++++ 2 files changed, 37 insertions(+), 14 deletions(-) diff --git a/src/gallium/auxiliary/util/u_blitter.c b/src/gallium/auxiliary/util/u_blitter.c index f93ef26ae73..c160716e6a7 100644 --- a/src/gallium/auxiliary/util/u_blitter.c +++ b/src/gallium/auxiliary/util/u_blitter.c @@ -964,16 +964,18 @@ void util_blitter_clear_depth_stencil(struct blitter_context *blitter, blitter_restore_CSOs(ctx); } -/* Clear a region of a depth stencil surface. */ -void util_blitter_flush_depth_stencil(struct blitter_context *blitter, - struct pipe_surface *dstsurf) +/* draw a rectangle across a region using a custom dsa stage - for r600g */ +void util_blitter_custom_depth_stencil(struct blitter_context *blitter, + struct pipe_surface *zsurf, + struct pipe_surface *cbsurf, + void *dsa_stage, float depth) { struct blitter_context_priv *ctx = (struct blitter_context_priv*)blitter; struct pipe_context *pipe = ctx->base.pipe; struct pipe_framebuffer_state fb_state; - assert(dstsurf->texture); - if (!dstsurf->texture) + assert(zsurf->texture); + if (!zsurf->texture) return; /* check the saved state */ @@ -981,8 +983,8 @@ void util_blitter_flush_depth_stencil(struct blitter_context *blitter, assert(blitter->saved_fb_state.nr_cbufs != ~0); /* bind CSOs */ - pipe->bind_blend_state(pipe, ctx->blend_keep_color); - pipe->bind_depth_stencil_alpha_state(pipe, ctx->dsa_flush_depth_stencil); + pipe->bind_blend_state(pipe, ctx->blend_write_color); + pipe->bind_depth_stencil_alpha_state(pipe, dsa_stage); pipe->bind_rasterizer_state(pipe, ctx->rs_state); pipe->bind_fs_state(pipe, blitter_get_fs_col(ctx, 0)); @@ -990,15 +992,30 @@ void util_blitter_flush_depth_stencil(struct blitter_context *blitter, pipe->bind_vertex_elements_state(pipe, ctx->velem_state); /* set a framebuffer state */ - fb_state.width = dstsurf->width; - fb_state.height = dstsurf->height; - fb_state.nr_cbufs = 0; - fb_state.cbufs[0] = 0; - fb_state.zsbuf = dstsurf; + fb_state.width = zsurf->width; + fb_state.height = zsurf->height; + fb_state.nr_cbufs = 1; + if (cbsurf) { + fb_state.cbufs[0] = cbsurf; + fb_state.nr_cbufs = 1; + } else { + fb_state.cbufs[0] = NULL; + fb_state.nr_cbufs = 0; + } + fb_state.zsbuf = zsurf; pipe->set_framebuffer_state(pipe, &fb_state); - blitter_set_dst_dimensions(ctx, dstsurf->width, dstsurf->height); - blitter->draw_rectangle(blitter, 0, 0, dstsurf->width, dstsurf->height, 0, + blitter_set_dst_dimensions(ctx, zsurf->width, zsurf->height); + blitter->draw_rectangle(blitter, 0, 0, zsurf->width, zsurf->height, depth, UTIL_BLITTER_ATTRIB_NONE, NULL); blitter_restore_CSOs(ctx); } + +/* flush a region of a depth stencil surface for r300g */ +void util_blitter_flush_depth_stencil(struct blitter_context *blitter, + struct pipe_surface *dstsurf) +{ + struct blitter_context_priv *ctx = (struct blitter_context_priv*)blitter; + util_blitter_custom_depth_stencil(blitter, dstsurf, NULL, + ctx->dsa_flush_depth_stencil, 0.0f); +} diff --git a/src/gallium/auxiliary/util/u_blitter.h b/src/gallium/auxiliary/util/u_blitter.h index e33d2e283f8..f9f96f25c77 100644 --- a/src/gallium/auxiliary/util/u_blitter.h +++ b/src/gallium/auxiliary/util/u_blitter.h @@ -203,6 +203,12 @@ void util_blitter_clear_depth_stencil(struct blitter_context *blitter, void util_blitter_flush_depth_stencil(struct blitter_context *blitter, struct pipe_surface *dstsurf); + +void util_blitter_custom_depth_stencil(struct blitter_context *blitter, + struct pipe_surface *zsurf, + struct pipe_surface *cbsurf, + void *dsa_stage, float depth); + /* The functions below should be used to save currently bound constant state * objects inside a driver.
