54 For older chipsets it's used for 3d acceleration only, but newer chipsets
57 for 2d acceleration (XVideo, exa(4)) as well.
61 drivers provide support for the following chipsets:
63 .Bl -tag -width XsavagedrmXXX -offset indent -compact
65 Intel i915, i945, i965, G3x, G4x
67 Mach64 (3D Rage Pro, Rage)
69 Matrox G[24]00, G[45]50
84 To make use of the driver:
88 The kernel must include
92 MesaLib and the video driver to be used must be compiled with DRI support
94 DRI must be enabled in the
