When the EXTENDED_NOTIFICATION_ROUTINE flag is specified, the u.BusResetNotification.ResetContext parameter points to a BUS_RESET_DATA structure. To register for extended bus reset notifications, a client driver uses the existing REQUEST_BUS_RESET_NOTIFICATION I/O request and specifies the new EXTENDED_NOTIFICATION_ROUTINE flag in the u.BusResetNotification.fulFlags parameter. This information can eliminate the need for a 1394 client driver to synchronize the retrieval of the generation count, node ids, and other information, with its bus reset notification handler. This notification returns information about the current generation of the bus (such as the generation count and node ids) to 1394 client drivers in the context of the bus reset notification. The 1394ohci.sys bus driver supports an extended bus reset notification. New IOCTL to Retrieve Configuration ROM.This topic summarizes the general DDI changes that support the new 1394 bus driver.
In addition, certain 1394 DDIs were changed to support greater speeds as defined by the 1394b specification and improved to simplify the development of 1394 client drivers. New DDIs were added to the new features supported by 1394ohci.sys. The new 1394 bus driver replaces the legacy IEEE bus drivers in port/miniport configuration-1394bus.sys and ochi1394.sys. Windows 7 includes 1394ohci.sys, a new IEEE 1394 bus driver that is implemented by using the kernel-mode driver framework (KMDF).
