|

39 | * The Direct Rendering Manager (DRM) is a device-independent kernel-level
|
---|
40 | * device driver that provides support for the XFree86 Direct Rendering
|
---|
41 | * Infrastructure (DRI).
|
---|
42 | *
|
---|
43 | * The DRM supports the Direct Rendering Infrastructure (DRI) in four major
|
---|
44 | * ways:
|
---|
45 | * -# The DRM provides synchronized access to the graphics hardware via
|
---|
46 | * the use of an optimized two-tiered lock.
|
---|
47 | * -# The DRM enforces the DRI security policy for access to the graphics
|
---|
48 | * hardware by only allowing authenticated X11 clients access to
|
---|
49 | * restricted regions of memory.
|
---|
50 | * -# The DRM provides a generic DMA engine, complete with multiple
|
---|
51 | * queues and the ability to detect the need for an OpenGL context
|
---|
52 | * switch.
|
---|
53 | * -# The DRM is extensible via the use of small device-specific modules
|
---|
54 | * that rely extensively on the API exported by the DRM module.
|
---|
