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 + + + +$XFree86: xc/programs/Xserver/hw/xfree86/os-support/linux/drm/kernel/README.drm,v 1.2 1999/09/27 14:59:24 dawes Exp $ -- cgit v1.2.3
