Peter Lekensteyn d099230cc3 nouveau: Support Optimus models for vga_switcheroo Newer nVidia cards with Optimus do not support/use the DSM switching functions. Instead, it require a DSM function to be called prior to bringing a device into D3 state. No other _DSM calls are necessary before/after enabling/disabling a device. Switching between discrete and integrated GPU is not supported by this Optimus _DSM call, therefore return on the switching method.

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:
