glide header files. The changes include: - Brian Paul's changes to the tdfx client-side 3D driver to make it dlopen() the correct glide library (Voodoo3 or Voodoo5). This allows both types of the glide library to co-exist, and allows Voodoo3/Voodoo5 cards to be mixed in multi-head configs. - DRM kernel driver changes to allow a driver to set up multiple instances (minor numbers), one for each card present that the driver supports. This is currently implemented and tested only for the tdfx DRM driver. - Add some missing missing <stdarg.h> includes. - Some log message cleanups. - Change the 2D tdfx driver to access VGA legacy registers via their PCI I/O space access points rather than their legacy addresses, and fix some problems with the way the VGA-related bits are initialised. Status: - With these changes, multi-head direct rendering works with multiple Voodoo3 and/or Voodoo5 cards. This has been tested with two PCI Voodoo3 cards and an AGP Voodoo5 card, and all permutations of those. Caveats: - Xinerama is not supported. If Xinerama is enabled, then direct rendering gets disabled. - The text mode on secondary screens will show junk after the X server exits. - On some hardware, starting the X server on multiple 3dfx cards will result in a hard lockup. One workaround is to enable APIC support in a uni-processor kernel, or use an SMP kernel. |

************************************************************ * For the very latest on DRI development, please see: * * http://dri.sourceforge.net/ * ************************************************************ The Direct Rendering Manager (drm) is a device-independent kernel-level device driver that provides support for the XFree86 Direct Rendering Infrastructure (DRI). The DRM supports the Direct Rendering Infrastructure (DRI) in four major ways: 1. The DRM provides synchronized access to the graphics hardware via the use of an optimized two-tiered lock. 2. The DRM enforces the DRI security policy for access to the graphics hardware by only allowing authenticated X11 clients access to restricted regions of memory. 3. The DRM provides a generic DMA engine, complete with multiple queues and the ability to detect the need for an OpenGL context switch. 4. The DRM is extensible via the use of small device-specific modules that rely extensively on the API exported by the DRM module. Documentation on the DRI is available from: http://precisioninsight.com/piinsights.html For specific information about kernel-level support, see: The Direct Rendering Manager, Kernel Support for the Direct Rendering Infrastructure http://precisioninsight.com/dr/drm.html Hardware Locking for the Direct Rendering Infrastructure http://precisioninsight.com/dr/locking.html A Security Analysis of the Direct Rendering Infrastructure http://precisioninsight.com/dr/security.html ************************************************************ * For the very latest on DRI development, please see: * * http://dri.sourceforge.net/ * ************************************************************
