The IOCTL_ACPI_ACQUIRE_GLOBAL_LOCK device control request is reserved for internal use only.Ī driver for a device can use the IOCTL_ACPI_ASYNC_EVAL_METHOD device control request to asynchronously evaluate an ACPI control method that is supported by the device. Retrieves an Authentication Grant Identifier (AGID) that identifies a secure session. The host's challenge key consists of a point on an elliptic curve and its associated signature. Sends the host's challenge key to the logical unit. Sends the host certificate to the logical unit. Reads the Advanced Access Content System (AACS)-specific volume identifier. Reads the Advanced Access Content System (AACS)-specific prerecorded media serial number. Queries the logical unit for the size of the buffer that is required to hold the Advanced Access Control System (AACS) Media Key Block (MKB). Queries the logical unit for the Media Key Block (MKB). Reads the Advanced Access Content System (AACS)-specific media identifier data. Reads the Advanced Access Content System (AACS) binding nonce starting at the specified byte offset on the disc, as part of the protocol for reading a protected data area. The challenge key consists of a point on an elliptic curve and its associated signature.
Queries the logical unit for the device's challenge key. Queries the logical unit for the device certificate. Reads the Advanced Access Content System (AACS) binding nonce starting at the specified byte offset on the disc, as part of the protocol for writing to a protected data area. Releases the Authentication Grant Identifier (AGID) that was obtained byIOCTL_AACS_START_SESSION. The driver has access to all operations provided by the IEC-61883 protocol driver through this request. The driver has access to all operations provided by the IEEE 1394 bus and its host controller through this request.Īn IEC-61883 client driver uses theIRP_MJ_INTERNAL_DEVICE_CONTROLIRP withIoControlCodeIOCTL_61883_CLASS to communicate with 1394 driver stack using the IEC-61883 protocol.
An IEEE 1394 driver uses the IRP_MJ_DEVICE_CONTROL IRP, withIoControlCodeIOCTL_1394_CLASS, to communicate with the bus driver.
