 * 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:
 */

#define NV_CTRL_TARGET_TYPE_GPU 1

/*
 * 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().

/*
 * 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.

/*
 * 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.
 *
 * See 'Key to Integer Attribute "Permissions"' at the top of this
 * file for a description of what these permission bits mean.
