# 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().
