|
|
* 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:
|
|
* -# The DRM provides synchronized access to the graphics hardware via
|
|
* the use of an optimized two-tiered lock.
|
|
* -# 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.
|
|
* -# The DRM provides a generic DMA engine, complete with multiple
|
|
* queues and the ability to detect the need for an OpenGL context
|
|
* switch.
|
|
* -# The DRM is extensible via the use of small device-specific modules
|
|
* that rely extensively on the API exported by the DRM module.
|
