(app-o)附录O: PROC接口
__________________________________________________________________________
proc 文件系统接口能使你得知驱动的运行时间,NVIDIA显卡和AGP的状态

这些信息保存在/proc/driver/nvidia的几个文件中.下面是对这些文件的简单介绍：

o version
列出已安装驱动的升级修正和建立在linux核心组件上的GUN C编辑器的版本

o cards/0...3
提供每一个已安装的NVIDIA图形适配器的信息 (型号名称, IRQ中断, BIOS 版本, 总线类型). 请注意,BIOS版本信息只有在X系统运行的时候才能发挥作用。

o agp/card
关于AGP接口的AGP性能方面的信息.

o agp/host-bridge
关于桥接方面的信息 (版本和AGP的性能).

o agp/status
当前的AGP状态. 当你的系统打开了AGP性能支持后,AGP驱动才能运行。这将显示出AGP的速率和状态信息的快速写入，以及Side BAND寻址。

这种AGP驱动是NVIDIA驱动（NVIDIA内置AGP驱动）或AGGART驱动（linux核心的agpgart.o驱动）的其中一个. 如果你看到"inactive"在AGPGART前面, 这表示这个 AGP 芯片组是AGPGART驱动的,但是当前并没有运作.

SBA和快速写入显示出是否每一个功能当前都在运作. 有几个因素决定这些功能是否在运作. 最主要的，AGP接口和桥接必须支持这些功能. 即使支持, 考虑到系统稳定性，驱动也不一定会打开这些功能. 最明显的就是AGP的快速写入。

__________________________________________________________________________

(app-p)附录P: XVMC支持
__________________________________________________________________________

X-Video Motion Compensation(XvMC)版本1.0 API（应用编程接口）的支持只有GeForce4并且只有only GeForce4系列产品.
现在适合dlopening的有静态连接库"libXvMCNVIDIA.a"和动态连接库
"libXvMCNVIDIA_dynamic.so"。
GeForce4 MX产品支持XvMC's "IDCT"和"motion-compensation"（动态补偿）
的加速性能. GeForce4 Ti 系列产品只支持motion-compensation（动态补偿）.
AI44 and IA44 subpictures
are supported. 4:2:0 Surfaces up to 2032x2032 are supported.

libXvMCNVIDIA监视环境变量XVMC_DEBUG,同时将一些调试信息(debug)输出到stderr（标准错误流），前提是设置了
相应的整数值。
'0' 禁止输出调试信息。
'1' 在失败的情况下输出调试信息。
'2' 或者进一步输出警告消息。

(app-q)附录Q: GLX支持
__________________________________________________________________________

GLX 1.2版本的性能支持有以下的扩展
GLX_EXT_visual_info
GLX_EXT_visual_rating
GLX_SGIX_fbconfig
GLX_SGIX_pbuffer
GLX_ARB_get_proc_address

对于以上扩展性能的描述, 请在下面站点察看OpenGL extension registry

GLX 1.3还没有被支持.

英文原文：

__________________________________________________________________________

(app-o) APPENDIX O: PROC INTERFACE
__________________________________________________________________________

The /proc filesystem interface allows you to obtain run-time information
about the driver, any installed NVIDIA graphics cards and the AGP status.

This information is held by several files in /proc/driver/nvidia. This is
a brief description for each one of these files:

  o version
      Lists the installed driver revision and the version of the GNU C
      compiler used to build the Linux kernel module.

  o cards/0...3
      Provides information about each of the installed NVIDIA graphics
      adapters (model name, IRQ, BIOS version, Bus Type). Please note
      that the BIOS version is only available while X is running.

  o agp/card
      Information about the installed AGP card's AGP capabilities.

  o agp/host-bridge
      Information about the host bridge (model and AGP capabilities).

  o agp/status
      The current AGP status. If AGP support has been enabled on your
      system, the AGP driver being used, the AGP rate and information
      about the status of AGP Fast Writes and Side Band Addressing is
      shown.

      The AGP driver is either one of NVIDIA (NVIDIA's built-in AGP
      driver) or AGPGART (the Linux kernel's agpgart.o driver). If
      you see "inactive" next to AGPGART, then this means that the
      AGP chipset was programmed by AGPGART, but is not currently in
      use.

      SBA and Fast Writes indicate whether either one of the features
      is currently in use. Please note that several factors decide if
      support for either will be enabled. First of all, both the AGP
      card and the host bridge must support the feature. Even if both
      do support it, the driver may decide not to use it in favor of
      system stability. This is particularly true of AGP Fast Writes.

__________________________________________________________________________

(app-p) APPENDIX P: XVMC SUPPORT
__________________________________________________________________________

This release includes support for the X-Video Motion Compensation
(XvMC) version 1.0 API on GeForce4 and only GeForce4 products.
There is a static library "libXvMCNVIDIA.a" and a dynamic one
"libXvMCNVIDIA_dynamic.so" which is suitable for dlopening.
GeForce4 MX products support both XvMC's "IDCT" and "motion-compensation"
levels of acceleration.  GeForce4 Ti products only support
the motion-compensation level.  AI44 and IA44 subpictures
are supported.  4:2:0 Surfaces up to 2032x2032 are supported.

libXvMCNVIDIA observes the XVMC_DEBUG environment variable and will
provide some debug output to stderr when set to an appropriate integer
value.  '0' disables debug output.  '1' enables debug output for failure
conditions.  '2' or higher enables output of warning messages.

__________________________________________________________________________

(app-q) APPENDIX Q: GLX SUPPORT
__________________________________________________________________________

This release supports GLX 1.2 with the following extensions
GLX_EXT_visual_info
GLX_EXT_visual_rating
GLX_SGIX_fbconfig
GLX_SGIX_pbuffer
GLX_ARB_get_proc_address

For a description of these extensions, please see the OpenGL extension
registry at http://oss.sgi.com/projects/ogl-sample/registry/index.html

GLX 1.3 is not yet supported.

flynng兄翻译的相当流畅，仅有以下几个小地方建议调整：

1、Lists the installed driver revision and the version of the GNU C
compiler used to build the Linux kernel module改为：列出已安装驱动的升级修正以及用来编译内核模块的GNU C编译器的版本。

2、the AGP rate and information
about the status of AGP Fast Writes and Side Band Addressing is
shown.改为：...将显示AGP Fast Writes（AGP快速写入）以及Side Band Addressing（边带寻址）状态的相关信息。

3、This release includes support for the X-Video Motion Compensation
(XvMC) version 1.0 API on GeForce4 and only GeForce4 products.
倒一下：有且仅有GeForce4 系列产品支持X-Video Motion Compensation(XvMC)1.0 API（应用编程接口）

4、AI44 and IA44 subpictures
are supported. 4:2:0 Surfaces up to 2032x2032 are supported.这句最麻烦，只能这样理解：此版本的驱动支持AI44及IA44 subpictures、4:2:0的YUV色彩空间转换、最高到2032x2032 分辨率的高级曲面（Higher Order Surfaces）。具体可以看看：
http://www.beareyes.com/2/lib/200202/19/20020219034.htm

5、'2' or higher enables output of warning messages改为：'2'或者更高的整数值启用警告消息输出
