Linus Torvalds 392c14beac Revert radeon AGP aperture offset changes This reverts the series of commits `67dbb4ea33` `281ab031a8` `47807ce381` that changed the GART VM start offset. It fixed some machines, but seems to continually interact badly with some X versions. Quoth Ben Herrenschmidt: "So I think at this point, the best is that we keep the old bogus code that at least is consistent with the bug in the server. I'm working on a big patch to X that reworks the memory map stuff completely and fixes those issues on the server side, I'll do a DRM patch matching this X fix as well so that the memory map is only ever set in one place and with what I hope is a correct algorithm..."

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:

    1. 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:
