![]() The IOCTL_ACPI_RELEASE_GLOBAL_LOCK device control request is reserved for internal use only.ĭescribes horizontal position bits 72:73. The IOCTL_ACPI_GET_DEVICE_SPECIFIC_DATA control code is used to get device specific data. The IOCTL_ACPI_EVAL_METHOD_V2_EX control code synchronously evaluates an ACPI control method that is supported by the device.Ī driver for a device can use the IOCTL_ACPI_GET_DEVICE_INFORMATION device control request to obtain fine-grained identification information about its device. The IOCTL_ACPI_EVAL_METHOD_V2 control code synchronously evaluates an ACPI control method that is supported by the device. The IOCTL_ACPI_EVAL_METHOD_V1_EX control code synchronously evaluates an ACPI control method that is supported by the device. The IOCTL_ACPI_EVAL_METHOD_V1 control code synchronously evaluates an ACPI control method that is supported by the device. The IOCTL_ACPI_ENUM_CHILDREN device control request can be used to enumerate the path and name of devices or named child objects in the ACPI namespace of the device to which this request is sent.Ī driver for a device can use the IOCTL_ACPI_EVAL_METHOD device control request to synchronously evaluate an ACPI control method that is supported by the device.Ī driver for a device can use the IOCTL_ACPI_EVAL_METHOD_EX device control request to synchronously evaluate an ACPI control method that is supported by a child device in the namespace of the device. ![]() The IOCTL_ACPI_ASYNC_EVAL_METHOD_V2_EX control code asynchronously evaluates an ACPI control method that is supported by the device. The IOCTL_ACPI_ASYNC_EVAL_METHOD_V2 control code asynchronously evaluates an ACPI control method that is supported by the device. The IOCTL_ACPI_ASYNC_EVAL_METHOD_V1_EX control code asynchronously evaluates an ACPI control method that is supported by the device.
