#### Constructors

###### fwupd_bios_setting_new

Creates a new bios setting.

since: 1.8.4

#### Instance methods

###### fwupd_bios_setting_add_possible_value

Adds a possible value to the attribute. This indicates one of the values the kernel driver will accept from userspace.

since: 1.8.4

###### fwupd_bios_setting_get_current_value

Gets the string representation of the current_value stored in an attribute from the kernel. This value is cached; so changing it outside of fwupd may may put it out of sync.

since: 1.8.4

###### fwupd_bios_setting_get_description

Gets the attribute description which is provided by some drivers to explain what they change.

since: 1.8.4

###### fwupd_bios_setting_get_id

Gets the unique attribute identifier for this attribute/driver.

since: 1.8.4

###### fwupd_bios_setting_get_kind

Gets the BIOS setting type used by the kernel interface.

since: 1.8.4

###### fwupd_bios_setting_get_lower_bound

Gets the lower bound for integer attributes or minimum length for string attributes.

since: 1.8.4

###### fwupd_bios_setting_get_name

Gets the attribute name.

since: 1.8.4

###### fwupd_bios_setting_get_path

Gets the path for the driver providing the attribute.

since: 1.8.4

###### fwupd_bios_setting_get_possible_values

Find all possible values for an enumeration attribute.

since: 1.8.4

###### fwupd_bios_setting_get_read_only

Determines if a BIOS setting is read only.

since: 1.8.4

###### fwupd_bios_setting_get_scalar_increment

Gets the scalar increment used for integer attributes.

since: 1.8.4

###### fwupd_bios_setting_get_upper_bound

Gets the upper bound for integer attributes or maximum length for string attributes.

since: 1.8.4

###### fwupd_bios_setting_has_possible_value

Finds out if a specific possible value was added to the attribute.

since: 1.8.4

###### fwupd_bios_setting_map_possible_value

Attempts to map a user provided string into strings that a `FwupdBiosSetting` can support. The following heuristics are used: - Ignore case sensitivity - Map obviously “positive” phrases into a value that turns on the `FwupdBiosSetting` - Map obviously “negative” phrases into a value that turns off the `FwupdBiosSetting`.

since: 1.8.4

###### fwupd_bios_setting_set_current_value

Sets the string stored in an attribute. This doesn’t change the representation in the kernel.

since: 1.8.4

###### fwupd_bios_setting_set_description

Sets the attribute description.

since: 1.8.4

###### fwupd_bios_setting_set_id

Sets the unique attribute identifier for this attribute.

since: 1.8.4

###### fwupd_bios_setting_set_kind

Sets the BIOS setting type used by the kernel interface.

since: 1.8.4

###### fwupd_bios_setting_set_lower_bound

Sets the lower bound used for BIOS integer attributes or max length for string attributes.

since: 1.8.4

###### fwupd_bios_setting_set_name

Sets the attribute name provided by a kernel driver.

since: 1.8.4

###### fwupd_bios_setting_set_path

Sets path to the attribute.

since: 1.8.4

###### fwupd_bios_setting_set_read_only

Configures whether an attribute is read only maximum length for string attributes.

since: 1.8.4

###### fwupd_bios_setting_set_scalar_increment

Sets the scalar increment used for BIOS integer attributes.

since: 1.8.4

###### fwupd_bios_setting_set_upper_bound

Sets the upper bound used for BIOS integer attributes or max length for string attributes.

since: 1.8.4

###### fwupd_bios_setting_write_value

Writes a new value into the setting if it is different from the current value.

since: 1.9.4
