/*
 * I915 DRM Driver for Solaris
 *
 * This driver provides the hardware 3D acceleration support for Intel
 * integrated video devices (e.g. i8xx/i915/i945 series chipsets), under the
 * DRI (Direct Rendering Infrastructure). DRM (Direct Rendering Manager) here
 * means the kernel device driver in DRI.
 *
 * I915 driver is a device dependent driver only, it depends on a misc module
 * named drm for generic DRM operations.
 *
 * This driver also calls into gfx and agpmaster misc modules respectively for
 * generic graphics operations and AGP master device support.
