From 635fe3e1927f812a69a68ec3e03d9ab7a2c3a5d9 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Sun, 28 Nov 2010 03:29:55 +0800 Subject: st/vega: vg_manager should care about only the color buffer. Move depth/stencil buffer, blend texture view, and alpha mask view creation to vg_context.c. --- src/gallium/state_trackers/vega/vg_manager.c | 182 --------------------------- 1 file changed, 182 deletions(-) (limited to 'src/gallium/state_trackers/vega/vg_manager.c') diff --git a/src/gallium/state_trackers/vega/vg_manager.c b/src/gallium/state_trackers/vega/vg_manager.c index 9254d7d1cf..03c8d22ba8 100644 --- a/src/gallium/state_trackers/vega/vg_manager.c +++ b/src/gallium/state_trackers/vega/vg_manager.c @@ -33,189 +33,14 @@ #include "pipe/p_screen.h" #include "util/u_memory.h" #include "util/u_inlines.h" -#include "util/u_format.h" #include "util/u_sampler.h" #include "vg_api.h" #include "vg_manager.h" #include "vg_context.h" #include "image.h" -#include "mask.h" #include "api.h" -static struct pipe_resource * -create_texture(struct pipe_context *pipe, enum pipe_format format, - VGint width, VGint height) -{ - struct pipe_resource templ; - - memset(&templ, 0, sizeof(templ)); - - if (format != PIPE_FORMAT_NONE) { - templ.format = format; - } - else { - templ.format = PIPE_FORMAT_B8G8R8A8_UNORM; - } - - templ.target = PIPE_TEXTURE_2D; - templ.width0 = width; - templ.height0 = height; - templ.depth0 = 1; - templ.last_level = 0; - - if (util_format_get_component_bits(format, UTIL_FORMAT_COLORSPACE_ZS, 1)) { - templ.bind = PIPE_BIND_DEPTH_STENCIL; - } else { - templ.bind = (PIPE_BIND_DISPLAY_TARGET | - PIPE_BIND_RENDER_TARGET | - PIPE_BIND_SAMPLER_VIEW); - } - - return pipe->screen->resource_create(pipe->screen, &templ); -} - -static struct pipe_sampler_view * -create_tex_and_view(struct pipe_context *pipe, enum pipe_format format, - VGint width, VGint height) -{ - struct pipe_resource *texture; - struct pipe_sampler_view view_templ; - struct pipe_sampler_view *view; - - texture = create_texture(pipe, format, width, height); - - if (!texture) - return NULL; - - u_sampler_view_default_template(&view_templ, texture, texture->format); - view = pipe->create_sampler_view(pipe, texture, &view_templ); - /* want the texture to go away if the view is freed */ - pipe_resource_reference(&texture, NULL); - - return view; -} - -static void -vg_context_update_alpha_mask_view(struct vg_context *ctx, - uint width, uint height) -{ - struct st_framebuffer *stfb = ctx->draw_buffer; - struct pipe_sampler_view *old_sampler_view = stfb->alpha_mask_view; - struct pipe_context *pipe = ctx->pipe; - - if (old_sampler_view && - old_sampler_view->texture->width0 == width && - old_sampler_view->texture->height0 == height) - return; - - /* - we use PIPE_FORMAT_B8G8R8A8_UNORM because we want to render to - this texture and use it as a sampler, so while this wastes some - space it makes both of those a lot simpler - */ - stfb->alpha_mask_view = create_tex_and_view(pipe, - PIPE_FORMAT_B8G8R8A8_UNORM, width, height); - - if (!stfb->alpha_mask_view) { - if (old_sampler_view) - pipe_sampler_view_reference(&old_sampler_view, NULL); - return; - } - - /* XXX could this call be avoided?
