From f00da2a3ff59c1a7104ac25a1c6eba5a6050ad68 Mon Sep 17 00:00:00 2001 From: Jakob Bornecrantz Date: Tue, 29 Sep 2009 16:07:11 -0700 Subject: i915g: Drop the simple sufix None of the other driver have a silly sufix, so just drop it. Nothing new added in this commit or any other commit but this is better marketing. --- src/gallium/drivers/i915/i915_context.c | 244 ++++++++++++++++++++++++++++++++ 1 file changed, 244 insertions(+) create mode 100644 src/gallium/drivers/i915/i915_context.c (limited to 'src/gallium/drivers/i915/i915_context.c') diff --git a/src/gallium/drivers/i915/i915_context.c b/src/gallium/drivers/i915/i915_context.c new file mode 100644 index 0000000000..e745f3342d --- /dev/null +++ b/src/gallium/drivers/i915/i915_context.c @@ -0,0 +1,244 @@ +/************************************************************************** + * + * Copyright 2003 Tungsten Graphics, Inc., Cedar Park, Texas. + * All Rights Reserved. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the + * "Software"), to deal in the Software without restriction, including + * without limitation the rights to use, copy, modify, merge, publish, + * distribute, sub license, and/or sell copies of the Software, and to + * permit persons to whom the Software is furnished to do so, subject to + * the following conditions: + * + * The above copyright notice and this permission notice (including the + * next paragraph) shall be included in all copies or substantial portions + * of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS + * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. + * IN NO EVENT SHALL TUNGSTEN GRAPHICS AND/OR ITS SUPPLIERS BE LIABLE FOR + * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, + * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE + * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + * + **************************************************************************/ + +#include "i915_context.h" +#include "i915_state.h" +#include "i915_screen.h" +#include "i915_batch.h" +#include "i915_texture.h" +#include "i915_reg.h" + +#include "draw/draw_context.h" +#include "pipe/p_defines.h" +#include "pipe/internal/p_winsys_screen.h" +#include "pipe/p_inlines.h" +#include "util/u_memory.h" +#include "pipe/p_screen.h" + + +/* + * Draw functions + */ + + +static boolean +i915_draw_range_elements(struct pipe_context *pipe, + struct pipe_buffer *indexBuffer, + unsigned indexSize, + unsigned min_index, + unsigned max_index, + unsigned prim, unsigned start, unsigned count) +{ + struct i915_context *i915 = i915_context(pipe); + struct draw_context *draw = i915->draw; + unsigned i; + + if (i915->dirty) + i915_update_derived(i915); + + /* + * Map vertex buffers + */ + for (i = 0; i < i915->num_vertex_buffers; i++) { + void *buf = pipe_buffer_map(pipe->screen, i915->vertex_buffer[i].buffer, + PIPE_BUFFER_USAGE_CPU_READ); + draw_set_mapped_vertex_buffer(draw, i, buf); + } + + /* + * Map index buffer, if present + */ + if (indexBuffer) { + void *mapped_indexes = pipe_buffer_map(pipe->screen, indexBuffer, + PIPE_BUFFER_USAGE_CPU_READ); + draw_set_mapped_element_buffer_range(draw, indexSize, + min_index, + max_index, + mapped_indexes); + } else { + draw_set_mapped_element_buffer(draw, 0, NULL); + } + + + draw_set_mapped_constant_buffer(draw, + i915->current.constants[PIPE_SHADER_VERTEX], + (i915->current.num_user_constants[PIPE_SHADER_VERTEX] * + 4 * sizeof(float))); + + /* + * Do the drawing + */ + draw_arrays(i915->draw, prim, start, count); + + /* + * unmap vertex/index buffers + */ + for (i = 0; i < i915->num_vertex_buffers; i++) { + pipe_buffer_unmap(pipe->screen, i915->vertex_buffer[i].buffer); + draw_set_mapped_vertex_buffer(draw, i, NULL); + } + + if (indexBuffer) { + pipe_buffer_unmap(pipe->screen, indexBuffer); + draw_set_mapped_element_buffer_range(draw, 0, start, start + count - 1, NULL); + } + + return TRUE; +} + +static boolean +i915_draw_elements(struct pipe_context *pipe, + struct pipe_buffer *indexBuffer, + unsigned indexSize, + unsigned prim, unsigned start, unsigned count) +{ + return i915_draw_range_elements(pipe, indexBuffer, + indexSize, + 0, 0xffffffff, + prim, start, count); +} + +static boolean +i915_draw_arrays(struct pipe_context *pipe, + unsigned prim, unsigned start, unsigned count) +{ + return i915_draw_elements(pipe, NULL, 0, prim, start, count); +} + + +/* + * Is referenced functions + */ + + +static unsigned int +i915_is_texture_referenced(struct pipe_context *pipe, + struct pipe_texture *texture, + unsigned face, unsigned level) +{ + /** + * FIXME: Return the corrent result.
