From d60b2c68552a2729dfdb33c2bac4822453cf8ae2 Mon Sep 17 00:00:00 2001 From: Jakob Bornecrantz Date: Wed, 24 Jun 2009 02:42:41 +0200 Subject: identity: Add new identity driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This driver does no transformation of the gallium calls going to the real driver, like the identity matrix. It is intended to be the basis for transforming and/or debug drivers like trace and rbug. Authors of this patch are: Michal Krol, orignal heavy lifting. José Fonesca, object wrapping code stolen from trace. Jakob Bornecrantz, put it all toghether and renamed a stuff. --- src/gallium/drivers/identity/id_objects.c | 182 ++++++++++++++++++++++++++++++ 1 file changed, 182 insertions(+) create mode 100644 src/gallium/drivers/identity/id_objects.c (limited to 'src/gallium/drivers/identity/id_objects.c') diff --git a/src/gallium/drivers/identity/id_objects.c b/src/gallium/drivers/identity/id_objects.c new file mode 100644 index 0000000000..e893e59940 --- /dev/null +++ b/src/gallium/drivers/identity/id_objects.c @@ -0,0 +1,182 @@ +/************************************************************************** + * + * 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. + * + **************************************************************************/ + +#include "util/u_memory.h" + +#include "id_public.h" +#include "id_screen.h" +#include "id_objects.h" + +struct pipe_buffer * +identity_buffer_create(struct identity_screen *id_screen, + struct pipe_buffer *buffer) +{ + struct identity_buffer *id_buffer;
