   2 # Makefile for the drm device driver.  This driver provides support for
   3 # the Direct Rendering Infrastructure (DRI) in XFree86 4.x.
   4 #

   6 # drm.o is a fake target -- it is never built
   7 # The real targets are in the module-list
   8 O_TARGET        := drm.o
   9 module-list     := gamma.o tdfx.o r128.o ffb.o mga.o i810.o
  10 export-objs     := $(patsubst %.o,%_drv.o,$(module-list))
  11
  12 # libs-objs are included in every module so that radical changes to the
  13 # architecture of the DRM support library can be made at a later time.
  14 #
  15 # The downside is that each module is larger, and a system that uses
  16 # more than one module (i.e., a dual-head system) will use more memory
  17 # (but a system that uses exactly one module will use the same amount of
  18 # memory).
  19 #
  20 # The upside is that if the DRM support library ever becomes insufficient
  21 # for new families of cards, a new library can be implemented for those new
  22 # cards without impacting the drivers for the old cards.  This is significant,
  23 # because testing architectural changes to old cards may be impossible, and
  24 # may delay the implementation of a better architecture.  We've traded slight
  25 # memory waste (in the dual-head case) for greatly improved long-term
  26 # maintainability.
