From: Jakob Bornecrantz Date: Tue, 3 Mar 2009 02:22:05 +0000 (+0100) Subject: st/dri2: Add DRI2 a state tracker X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1d060e36f248b2c1d2575d1e2cbd362b8345ae55;p=mesa.git st/dri2: Add DRI2 a state tracker This was based of the unfinnished code that Keith Whitwell started on but never finnished. I moved the code from the glx directory because dri drivers can be used for more things then just glx. --- diff --git a/src/gallium/state_trackers/dri2/Makefile b/src/gallium/state_trackers/dri2/Makefile new file mode 100644 index 00000000000..47750e997e9 --- /dev/null +++ b/src/gallium/state_trackers/dri2/Makefile @@ -0,0 +1,28 @@ +TOP = ../../../.. +include $(TOP)/configs/current + +LIBNAME = dri2drm + +LIBRARY_INCLUDES = \ + -I$(TOP)/include \ + -I$(TOP)/src/mesa \ + -I$(TOP)/src/mesa/drivers/dri/common \ + -I$(TOP)/src/mesa/main \ + $(shell pkg-config --cflags-only-I libdrm) + + +C_SOURCES = \ + dri_context.c \ + dri_screen.c \ + dri_drawable.c \ + dri_extensions.c + +# $(TOP)/src/mesa/drivers/dri/common/utils.c \ + $(TOP)/src/mesa/drivers/dri/common/vblank.c \ + $(TOP)/src/mesa/drivers/dri/common/dri_util.c \ + $(TOP)/src/mesa/drivers/dri/common/xmlconfig.c \ + $(TOP)/src/mesa/drivers/common/driverfuncs.c \ + $(TOP)/src/mesa/drivers/dri/common/texmem.c \ + $(TOP)/src/mesa/drivers/dri/common/drirenderbuffer.c + +include ../../Makefile.template diff --git a/src/gallium/state_trackers/dri2/dri_context.c b/src/gallium/state_trackers/dri2/dri_context.c new file mode 100644 index 00000000000..a8a94be176c --- /dev/null +++ b/src/gallium/state_trackers/dri2/dri_context.c @@ -0,0 +1,168 @@ +/************************************************************************** + * + * Copyright 2009, VMware, Inc. + * 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 VMWARE 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. + * + **************************************************************************/ +/* + * Author: Keith Whitwell + * Author: Jakob Bornecrantz + */ + +#include "dri_screen.h" + +#include "dri_drawable.h" + + +#include "state_tracker/drm_api.h" +#include "state_tracker/st_public.h" +#include "state_tracker/st_context.h" +#include "pipe/p_context.h" + +#include "dri_context.h" + +#include "util/u_memory.h" + + +GLboolean +dri_create_context(const __GLcontextModes *visual, + __DRIcontextPrivate *cPriv, + void *sharedContextPrivate) +{ + __DRIscreenPrivate *sPriv = cPriv->driScreenPriv;
