/*
 * Attribute Targets
 *
 * Targets define attribute groups.  For example, some attributes are only
 * valid to set on a GPU, others are only valid when talking about an
 * X Screen.  Target types are then what is used to identify the target
 * group of the attribute you wish to set/query.
 *
 * Here are the supported target types:

/*
 * Attributes
 *
 * Some attributes may only be read; some may require a display_mask
 * argument and others may be valid only for specific target types.
 * This information is encoded in the "permission" comment after each
 * attribute #define, and can be queried at run time with
 * XNVCTRLQueryValidAttributeValues() and/or
 * XNVCTRLQueryValidTargetAttributeValues()
 *
 * Key to Integer Attribute "Permissions":
 *
 * R: The attribute is readable (in general, all attributes will be
 *    readable)
 *
 * W: The attribute is writable (attributes may not be writable for
 *    various reasons: they represent static system information, they
 *    can only be changed by changing an XF86Config option, etc).
 *
 * 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
 *    in the bitmask represents a display device; it is these bits which
 *    should be used as the display_mask when dealing with attributes
 *    designated with "D" below.  For attributes that do not require the
 *    display mask, the argument is ignored.
 *
 * G: The attribute may be queried using an NV_CTRL_TARGET_TYPE_GPU
 *    target type via XNVCTRLQueryTargetAttribute().
 *
 * F: The attribute may be queried using an NV_CTRL_TARGET_TYPE_FRAMELOCK
 *    target type via XNVCTRLQueryTargetAttribute().
 *
 * X: When Xinerama is enabled, this attribute is kept consistent across
 *    all Physical X Screens;  Assignment of this attribute will be
 *    broadcast by the NVIDIA X Driver to all X Screens.
 *
 * V: The attribute may be queried using an NV_CTRL_TARGET_TYPE_VCSC
 *    target type via XNVCTRLQueryTargetXXXAttribute().
 * 
 * NOTE: Unless mentioned otherwise, all attributes may be queried using
 *       an NV_CTRL_TARGET_TYPE_X_SCREEN target type via

 * - 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 knownthat a valid
 * bi-level or tri-level sync is connected set
 * NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECT_MODEappropriately 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
 *
 * - specify any custom Color Space Conversion (CSC) matrix, offset,
 * and scale with XNVCTRLSetGvoColorConversion().
 *
 * - 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_GLX_LOCKED
 * event will be sent when a GLX client locks the GVO output.
