[sir_richard] 46693: [NTOS]: Implement Configuration Manager routines for building a driver list, sorting it, detecting circular dependencies and ordering, combining groups, tags, group orders and tag orders, etc. Replaces the "drvrlist" I/O interface currently in ReactOS.

Author: sir_richard Date: Sat Apr 3 09:44:38 2010 New Revision: 46693 URL: http://svn.reactos.org/svn/reactos?rev=46693&view=rev Log: [NTOS]: Implement Configuration Manager routines for building a driver list, sorting it, detecting circular dependencies and ordering, combining groups, tags, group orders and tag orders, etc. Replaces the "drvrlist" I/O interface currently in ReactOS. [NTOS]: Use the new Cm interface in IopInitializeSystemDrivers to parse the ordered list of system drivers to load. Make it use ZwLoadDriver directly instead of having a hacked IopLoadDriver function. [NTOS]: Drivers should not show up loading n times a reboot now (some drivers seemed to do this in the past when they failed to load). [NTOS]: The system driver code could be further improved by checknig if the driver has already been loaded, or attempted and failed to load, but it is already much better now than in the past. [PERF]: Boot-time improvement since the new system driver loading code uses low-level Cm interfaces (portability side-effect: can be shared with FreeLDR) instead of the complex parse-based object-manager-based system-calls.
