Sent to direct a driver to process a new device or changes to the configuration. Enumerators should retrieve the filtered logical configuration for the indicated device node and modify the requirements as needed. For example, the PCMCIA driver removes unsupported IRQs and pre-allocates IO port and memory ranges.
Initially, the filtered requirements are identical to the basic requirements. An enumerator may alter the requirements of its own device node as well those of the indicated device node. When a device driver processes this message, it should look only at the filtered requirements list only.
Use the CONFIGMG_Get_First_Log_Conf or CONFIGMG_Get_Alloc_Log_Conf to retrieve the filtered logical configuration (FILTERED_LOG_CONF) for this device node.
