> 4. Technical Description
> Addition ioctl support for Intel G33/Q33,Q35 chipsets in i915 driver
>
> 1. Summary
> DRM (direct rendering management) kernel module and i915 driver were
> introduced to Solaris in
> PSARC 2004/801. The ioctl's exported by this driver include both hardware
> independent
> and hardware dependent ones. Recently, Intel released their G33/Q33,Q35
> chipsets
> with embedded graphics that required a new Intel specific ioctl in the
> driver.
> This case documents this new ioctl.
>
> 2. Discussion
> The third argument of the prefixioctl (ioctl(9E)) should point to the
> structure
> below. The usage of the first argument 'dev' and the second argument
> 'cmd' follow
> the same pattern of other ioctl's.
>
> struct drm_i915_hws_addr {
> uint64_t addr; /* the offset of hardware status page */
