From: Keith Whitwell Date: Wed, 8 Aug 2007 08:28:57 +0000 (+0100) Subject: Checkpoint of a super-simplified i915 driver in the pipe model. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=01c35b52a1fccbe4253a96b9c0506ef6c991e44f;p=mesa.git Checkpoint of a super-simplified i915 driver in the pipe model. Doesn't yet compile, but when it does, it will only draw gouraud tris and even those will be as simple as possible. Needs some 'winsys' support also before that can happen. --- diff --git a/src/mesa/pipe/i915simple/Makefile b/src/mesa/pipe/i915simple/Makefile new file mode 100644 index 00000000000..4170349893c --- /dev/null +++ b/src/mesa/pipe/i915simple/Makefile @@ -0,0 +1,31 @@ + +TOP = ../../../.. +include $(TOP)/configs/current + +LIBNAME = i915simple + +DRIVER_SOURCES = \ + i915_blit.c \ + i915_buffer.c \ + i915_clear.c \ + i915_context.c \ + i915_context.c \ + i915_debug.c \ + i915_regions.c \ + i915_state.c \ + i915_state_derived.c \ + i915_state_emit.c \ + i915_state_fragprog.c \ + i915_prim_emit.c \ + i915_surface.c + +C_SOURCES = \ + $(COMMON_SOURCES) \ + $(DRIVER_SOURCES) + +ASM_SOURCES = + +include ../Makefile.template + +symlinks: + diff --git a/src/mesa/pipe/i915simple/i915_batch.h b/src/mesa/pipe/i915simple/i915_batch.h new file mode 100644 index 00000000000..77008eee140 --- /dev/null +++ b/src/mesa/pipe/i915simple/i915_batch.h @@ -0,0 +1,44 @@ +/************************************************************************** + * + * Copyright 2007 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. + * + **************************************************************************/ + +#ifndef I915_BATCH_H +#define I915_BATCH_H + +#define BATCH_LOCALS + +#define BEGIN_BATCH( dwords, relocs ) \ + i915->winsys->batch_start( i915->winsys, dwords, relocs ) + +#define OUT_BATCH( dword ) \ + i915->winsys->batch_dword( i915->winsys, dword ) + +#define OUT_RELOC( buf, flags, delta ) \ + i915->winsys->batch_reloc( i915->winsys, buf, flags, delta ) + +#define ADVANCE_BATCH() + +#endif diff --git a/src/mesa/pipe/i915simple/i915_blit.c b/src/mesa/pipe/i915simple/i915_blit.c new file mode 100644 index 00000000000..c4eafa71d45 --- /dev/null +++ b/src/mesa/pipe/i915simple/i915_blit.c @@ -0,0 +1,157 @@ +/************************************************************************** + * + * 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 + +#include "mtypes.h" + +#include "i915_context.h" +#include "i915_winsys.h" +#include "i915_blit.h" +#include "i915_reg.h" +#include "i915_batch.h" + + +void +i915_fill_blit(struct i915_context *i915, + GLuint cpp, + GLshort dst_pitch, + struct pipe_buffer_handle *dst_buffer, + GLuint dst_offset, + GLshort x, GLshort y, + GLshort w, GLshort h, + GLuint color) +{ + GLuint BR13, CMD;
