Intel 2.18 Linux视频驱动发布
二月24日，Chris Wilson 宣布，Intel 2.18 Linux视频驱动已可以下载。
为了使所有的掩码、目的地址和源地址都能同时被映射到光圈中，Intel 2.18 视频驱动对最大对象的体积作了限制。
该驱动从版本2.15.901 开始出现的一个错误地剪除多边形的退化，以及在持续渲染过程中处理用户输入时出现等待等问题均已被修复。
“正如你可能已经注意到的，我们现在又新增了两个实验性后端，SNA和Glamor。SNA是传统DDX模型的延续，拥有专业的渲染器以尝试与挖掘硬件可提供的极限。”
“Glamor则是另一个选择，可将所有渲染传递到一个新的库，该库试图操纵OpenGL加速绘图操作。”
“二者都要求你拥有最新的图像栈（ Glamor 还对你所编译的mesa以及sxerver有所限制）并已选择以 --enable-sna 或--enable-glamor 的方式编译。” 邮件列表声明 中的Chris Wilson 表示。
最后但同样重要的是，为了避免触及每进程的VMA（有效存储地址）的极限，VMA的数量也有限制。

Intel 2.18 Video Driver for Linux Released
Chris Wilson announced a few minutes ago, February 24th, that version 2.18.0 of the xf86-video-intel graphics driver for Linux is available for download.
Intel 2.18 video driver brings a limit to maximum object size in order for all of the mask, destination and source to be simultaneously mapped into the aperture.
A regression from version 2.15.901 of the Intel driver, that incorrectly clipped polygons was fixed, as well as the latency in processing user-input during continuous rendering.
" As you may have noticed, we now have two additional experimental acceleration backends, SNA and Glamor. SNA is a continuation of the traditional DDX model and has a specialised renderer to try and exploit the full limits of the available hardware."
" Glamor is an alternate that hands over all the rendering to a new library that tries to leverage OpenGL to accelerate the drawing operations."
" Both require you to have an uptodate graphics stack (with additional restrictions on how you have compiled mesa and the xserver for glamor) and to opt in by either compiling with --enable-sna or with --enable-glamor." - said Chris Wilson in the mailing-list announcement.
Last but not least, in order to avoid hitting the per-process VMA limit, the number of VMA cached was limited.
