6 | The Direct Rendering Manager (drm) is a device-independent kernel-level | ||
7 | device driver that provides support for the XFree86 Direct Rendering | ||
8 | Infrastructure (DRI). | ||
9 | |||
10 | The DRM supports the Direct Rendering Infrastructure (DRI) in four major | ||
11 | ways: | ||
12 | |||
13 | 1. The DRM provides synchronized access to the graphics hardware via | ||
14 | the use of an optimized two-tiered lock. | ||
15 | |||
16 | 2. The DRM enforces the DRI security policy for access to the graphics | ||
17 | hardware by only allowing authenticated X11 clients access to | ||
18 | restricted regions of memory. | ||
19 | |||
20 | 3. The DRM provides a generic DMA engine, complete with multiple | ||
21 | queues and the ability to detect the need for an OpenGL context | ||
22 | switch. | ||
23 | |||
24 | 4. The DRM is extensible via the use of small device-specific modules | ||
25 | that rely extensively on the API exported by the DRM module. | ||
26 | |||
27 | |||
28 | Documentation on the DRI is available from: | ||
