 * 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 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().
 * 
 * NOTE: Unless mentioned otherwise, all attributes may be queried using
 *       an NV_CTRL_TARGET_TYPE_X_SCREEN target type via

 * 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, 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.

/*
 * NV_CTRL_STRING_OPERATION_GVI_CONFIGURE_STREAMS - Configure the streams-
 * to-jack+channel topology for a GVI (Graphics capture board).
 *
 * The string input to GVI_CONFIGURE_STREAMS may be NULL.  If this is the
 * case, then the current topology is returned.
 *
 * If the input string to GVI_CONFIGURE_STREAMS is not NULL, the string
 * is interpreted as a semicolon (";") separated list of comma-separated
 * lists of "option=value" pairs that define a stream's composition.  The
 * available options and their values are:
 *
 *   "stream": Defines which stream this comma-separated list describes.
 *             Valid values are the integers between 0 and
 *             NV_CTRL_GVI_NUM_STREAMS-1 (inclusive).
 *
 *   "linkN":  Defines a jack+channel pair to use for the given link N.
 *             Valid options are the string "linkN", where N is an integer
 *             between 0 and NV_CTRL_GVI_MAX_LINKS_PER_STREAM-1 (inclusive).
 *             Valid values for these options are strings of the form
 *             "jackX" and/or "jackX.Y", where X is an integer between 0 and
 *             NV_CTRL_GVI_NUM_JACKS-1 (inclusive), and Y (optional) is an
 *             integer between 0 and NV_CTRL_GVI_MAX_CHANNELS_PER_JACK-1
 *             (inclusive).
 *
 * An example input string might look like:
 *
 *   "stream=0, link0=jack0, link1=jack1; stream=1, link0=jack2.1"
 * 
 *   This example specifies two streams, stream 0 and stream 1.  Stream 0
 *   is defined to capture link0 data from the first channel (channel 0) of
 *   BNC jack 0 and link1 data from the first channel of BNC jack 1.  The
 *   second stream (Stream 1) is defined to capture link0 data from channel 1
 *   (second channel) of BNC jack 2.
 *
 * This example shows a possible configuration for capturing 3G input:
 *
 *   "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.
 *
 *
 * 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 requires a display mask.
 * 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.
