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://dri.freedesktop.org/wiki/Documentation + http://sourceforge.net/project/showfiles.php?group_id=387 + http://dri.sourceforge.net/doc/ + +For specific information about kernel-level support, see: + + The Direct Rendering Manager, Kernel Support for the Direct Rendering + Infrastructure + http://dri.sourceforge.net/doc/drm_low_level.html + + Hardware Locking for the Direct Rendering Infrastructure + http://dri.sourceforge.net/doc/hardware_locking_low_level.html + + A Security Analysis of the Direct Rendering Infrastructure + http://dri.sourceforge.net/doc/security_low_level.html |
