Function Documentation

int i810_driver_device_is_agp

(

struct drm_device *

dev

)

Determine if the device really is AGP or not.

All Intel graphics chipsets are treated as AGP, even if they are really PCI-e.

Parameters

dev	The device to be tested.

Returns

A value of 1 is always retured to indictate every i810 is AGP.
