     * 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.
     *
     *    Alternatively, NV-CONTROL versions 1.27 and greater allow these
     *    attributes to be accessed via display target types, in which case
     *    the display_mask 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 XNVCTRLQueryTargetAttribute().
     *
     * I: The attribute may be queried using an NV_CTRL_TARGET_TYPE_GVI target type
     *    via XNVCTRLQueryTargetAttribute().
     *
     * Q: The attribute is a 64-bit integer attribute;  use the 64-bit versions
     *    of the appropriate query interfaces.
     *
     * C: The attribute may be queried using an NV_CTRL_TARGET_TYPE_COOLER target
     *    type via XNVCTRLQueryTargetAttribute().
     *
     * S: The attribute may be queried using an NV_CTRL_TARGET_TYPE_THERMAL_SENSOR
     *    target type via XNVCTRLQueryTargetAttribute().
     *
     * T: The attribute may be queried using an
     *    NV_CTRL_TARGET_TYPE_3D_VISION_PRO_TRANSCEIVER target type
     *    via XNVCTRLQueryTargetAttribute().
     *
     * NOTE: Unless mentioned otherwise, all attributes may be queried using

     * 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_GVIO_DETECTED_VIDEO_FORMAT attribute; note that Input video
     * format can only be queried after SYNC_SOURCE is specified.
     *
     * - specify the NV_CTRL_GVIO_REQUESTED_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 using the GLX_NV_present_video extension, call
     * glXBindVideoDeviceNV() to bind the GVO video device to current
     * OpenGL context.
     *
     * 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 the next MetaMode is set that uses the GVO display
     * device, or when a GLX pbuffer is bound to the GVO output (with
     * glXBindVideoImageNV()).
     *
     * Note that GLX_NV_video_out/GLX_NV_present_video and X screen use
     * are mutually exclusive.  If a MetaMode is currently using the GVO
     * device, then glXGetVideoDeviceNV and glXBindVideoImageNV() will
     * fail.  Similarly, if a GLX client has locked the GVO output (via
     * glXGetVideoDeviceNV or glXBindVideoImageNV), then setting a
     * MetaMode that uses the GVO device will fail.  The
     * NV_CTRL_GVO_GLX_LOCKED event will be sent when a GLX client locks
     * the GVO output.

     *   "stream=0, link0=jack0.0, link1=jack0.1"
     *
     * Applications should query the following attributes to determine
     * possible combinations:
     *
     *   NV_CTRL_GVI_MAX_STREAMS
     *   NV_CTRL_GVI_MAX_LINKS_PER_STREAM
     *   NV_CTRL_GVI_NUM_JACKS
     *   NV_CTRL_GVI_MAX_CHANNELS_PER_JACK
     *
     * Note: A jack+channel pair can only be tied to one link/stream.
     *
     * Upon successful configuration or querying of this attribute, a string
     * representing the current topology for all known streams on the device
     * will be returned.  On failure, NULL is returned.
     *
     * Note: Setting this attribute may also result in the following
     *       NV-CONTROL attributes being reset on the GVI device (to ensure
     *       the configuration remains valid):
     *           NV_CTRL_GVIO_REQUESTED_VIDEO_FORMAT
     *           NV_CTRL_GVI_REQUESTED_STREAM_BITS_PER_COMPONENT
     *           NV_CTRL_GVI_REQUESTED_STREAM_COMPONENT_SAMPLING

     * CTRLAttributeValidValuesRec -
     *
     * structure and related defines used by
     * XNVCTRLQueryValidAttributeValues() to describe the valid values of
     * a particular attribute.  The type field will be one of:
     *
     * ATTRIBUTE_TYPE_INTEGER : the attribute is an integer value; there
     * is no fixed range of valid values.
     *
     * ATTRIBUTE_TYPE_BITMASK : the attribute is an integer value,
     * interpretted as a bitmask.
     *
     * ATTRIBUTE_TYPE_BOOL : the attribute is a boolean, valid values are
     * either 1 (on/true) or 0 (off/false).
     *
     * ATTRIBUTE_TYPE_RANGE : the attribute can have any integer value
     * between NVCTRLAttributeValidValues.u.range.min and
     * NVCTRLAttributeValidValues.u.range.max (inclusive).
     *
     * ATTRIBUTE_TYPE_INT_BITS : the attribute can only have certain
     * integer values, indicated by which bits in
     * NVCTRLAttributeValidValues.u.bits.ints are on (for example: if bit
     * 0 is on, then 0 is a valid value; if bit 5 is on, then 5 is a valid
     * value, etc).  This is useful for attributes like NV_CTRL_FSAA_MODE,
     * which can only have certain values, depending on GPU.
     *
     * ATTRIBUTE_TYPE_64BIT_INTEGER : the attribute is a 64 bit integer value;
     * there is no fixed range of valid values.
     *
     * ATTRIBUTE_TYPE_STRING : the attribute is a string value; there is no fixed
     * range of valid values.
     *
     * ATTRIBUTE_TYPE_BINARY_DATA : the attribute is binary data; there is
     * no fixed range of valid values.
     *
     * ATTRIBUTE_TYPE_STRING_OPERATION : the attribute is a string; there is
     * no fixed range of valid values.
     *
     *
     * The permissions field of NVCTRLAttributeValidValuesRec is a bitmask
     * that may contain:
     *
     * ATTRIBUTE_TYPE_READ      - Attribute may be read (queried.)
     * ATTRIBUTE_TYPE_WRITE     - Attribute may be written to (set.)
     * ATTRIBUTE_TYPE_DISPLAY   - Attribute is valid for display target types
     *                            (requires a display_mask if queried via
     *                            a GPU or X screen.)
     * ATTRIBUTE_TYPE_GPU       - Attribute is valid for GPU target types.
     * ATTRIBUTE_TYPE_FRAMELOCK - Attribute is valid for Frame Lock target types.
     * ATTRIBUTE_TYPE_X_SCREEN  - Attribute is valid for X Screen target types.
     * ATTRIBUTE_TYPE_XINERAMA  - Attribute will be made consistent for all
     *                            X Screens when the Xinerama extension is enabled.
     * ATTRIBUTE_TYPE_VCSC      - Attribute is valid for Visual Computing System
     *                            target types.
     * ATTRIBUTE_TYPE_GVI       - Attribute is valid for Graphics Video In target
     *                            types.
     * ATTRIBUTE_TYPE_COOLER    - Attribute is valid for Cooler target types.
     * ATTRIBUTE_TYPE_3D_VISION_PRO_TRANSCEIVER - Attribute is valid for 3D Vision
     *                                            Pro Transceiver target types.
