 * W: The attribute is writable (attributes may not be writable for
 *    various reasons: they represent static system information, they

 *
 * D: The attribute requires the display mask argument.  The
 *    attributes NV_CTRL_CONNECTED_DISPLAYS and NV_CTRL_ENABLED_DISPLAYS
 *    will be a bitmask of what display devices are connected and what
 *    display devices are enabled for use in X, respectively.  Each bit

/*
 * The NV_CTRL_GVO_* integer attributes are used to configure GVO
 * (Graphics to Video Out).  This functionality is available, for
 * example, on the Quadro FX 4000 SDI graphics board.
 *
 * The following is a typical usage pattern for the GVO attributes:
 *
 * - query NV_CTRL_GVO_SUPPORTED to determine if the X screen supports GV0.
 *
 * - specify NV_CTRL_GVO_SYNC_MODE (one of FREE_RUNNING, GENLOCK, or
 * FRAMELOCK); if you specify GENLOCK or FRAMELOCK, you should also
 * specify NV_CTRL_GVO_SYNC_SOURCE.
 * 
 * - Use NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECTED and
 * NV_CTRL_GVO_SDI_SYNC_INPUT_DETECTED to detect what input syncs are
 * present.
 * 
 * (If no analog sync is detected but it is known that a valid
 * bi-level or tri-level sync is connected set
 * NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECT_MODE appropriately and
 * retest with NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECTED).
 *
 * - if syncing to input sync, query the
 * NV_CTRL_GVO_INPUT_VIDEO_FORMAT attribute; note that Input video
 * format can only be queried after SYNC_SOURCE is specified.
 *
 * - specify the NV_CTRL_GVO_OUTPUT_VIDEO_FORMAT
 *
 * - specify the NV_CTRL_GVO_DATA_FORMAT
 *
 * - if using the GLX_NV_video_out extension to display one or more
 * pbuffers, call glXGetVideoDeviceNV() to lock the GVO output for use
 * by the GLX client; then bind the pbuffer(s) to the GVO output with
 * glXBindVideoImageNV() and send pbuffers to the GVO output with
 * glXSendPbufferToVideoNV(); see the GLX_NV_video_out spec for more
 * details.
 *
 * - if, rather than using the GLX_NV_video_out extension to display
 * GLX pbuffers on the GVO output, you wish display the X screen on
 * the GVO output, set NV_CTRL_GVO_DISPLAY_X_SCREEN to
 * NV_CTRL_GVO_DISPLAY_X_SCREEN_ENABLE.
 *
 * Note that setting most GVO attributes only causes the value to be
 * cached in the X server.  The values will be flushed to the hardware
 * either when NV_CTRL_GVO_DISPLAY_X_SCREEN is enabled, or when a GLX
 * pbuffer is bound to the GVO output (with glXBindVideoImageNV()).
 *
 * Note that GLX_NV_video_out and NV_CTRL_GVO_DISPLAY_X_SCREEN are
 * mutually exclusive.  If NV_CTRL_GVO_DISPLAY_X_SCREEN is enabled,
 * then glXGetVideoDeviceNV will fail.  Similarly, if a GLX client has
 * locked the GVO output (via glXGetVideoDeviceNV), then
 * NV_CTRL_GVO_DISPLAY_X_SCREEN will fail.  The NV_CTRL_GVO_LOCKED
 * event will be sent when a GLX client locks the GVO output.
