   1 #
   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
  10 module-list     := gamma.o tdfx.o r128.o ffb.o mga.o i810.o
  11 export-objs     := $(patsubst %.o,%_drv.o,$(module-list))
  12
  13 # libs-objs are included in every module so that radical changes to the
  14 # architecture of the DRM support library can be made at a later time.
  15 #
  16 # The downside is that each module is larger, and a system that uses
  17 # more than one module (i.e., a dual-head system) will use more memory
  18 # (but a system that uses exactly one module will use the same amount of
  19 # memory).
  20 #
  21 # The upside is that if the DRM support library ever becomes insufficient
  22 # for new families of cards, a new library can be implemented for those new
  23 # cards without impacting the drivers for the old cards.  This is significant,
  24 # because testing architectural changes to old cards may be impossible, and
  25 # may delay the implementation of a better architecture.  We've traded slight
  26 # memory waste (in the dual-head case) for greatly improved long-term
  27 # maintainability.
