 From yesterday's "Jan-March 2005 Status Report":

-----------------------------------------------------------------------------------------------------------

drm

   URL: http://r300.sourceforge.net/

   Contact: Eric Anholt <[email protected]>

   A DRM update was finally committed to -current on 2005-04-15, after
   jhb@ did the necessary fix to vm_mmap. New development drivers were
   added for mach64 and r300 (see URL for info). The nearly-finished code
   for savage and i915 were also added, but left disconnected from the
   build. However, the most visible change is likely the support for
   texture tiling, color tiling, and HyperZ on Radeons, which (with
   updated userland) likely provide a 50-75% framerate increase in many
   applications.

  Open tasks:

    1. Find someone with newbus knowledge to figure out why the i915
       won't attach to drmsub0.
    2. Finish porting the savage driver.
    3. Integrate busdma code from Tonnerre (NetBSD).

---------------------------------------------------------------------------------------------------------

So, drm on the i915 isn't even fully supported in -CURRENT yet, as I
read it....
