It provides a +DRM interface for GEM, which is basically sufficient to have DRI2 +working. But it does not provide KMS. And interface to 2d and 3d +cores is via different other devices (/dev/kgsl-*). This is not +quite how I'd write a DRM driver, but at this stage it is useful for +xf86-video-freedreno and fdre (and eventual gallium driver) to be +able to work on existing kernel driver from QCOM, to allow to +capture cmdstream dumps from the binary blob drivers without having +to reboot. So libdrm_freedreno attempts to hide most of the crazy. +The intention is that when there is a proper kernel driver, it will +be mostly just changes in libdrm_freedreno to adapt the gallium +driver and xf86-video-freedreno (ignoring the fbdev->KMS changes). + +So don't look at freedreno as an example of how to write a libdrm +module or a DRM driver.. it is just an attempt to paper over a non- +standard kernel driver architecture. diff --git a/freedreno/freedreno_bo.c b/freedreno/freedreno_bo.c new file mode 100644 index 00000000..4f566e10 --- /dev/null +++ b/freedreno/freedreno_bo.c @@ -0,0 +1,274 @@ +/* -*- mode: C; c-file-style: "k&r"; tab-width 4; indent-tabs-mode: t; -*- */ + +/* + * Copyright (C) 2012 Rob Clark <robclark@freedesktop.org> + * + * 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, sublicense, + * 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 NONINFRINGEMENT.
