# Makefile for the drm device driver. This driver provides support for
# the Direct Rendering Infrastructure (DRI) in XFree86 4.x.
#
# drm.o is a fake target -- it is never built
# The real targets are in the module-list
O_TARGET := drm.o
module-list := gamma.o tdfx.o r128.o ffb.o mga.o i810.o
export-objs := $(patsubst %.o,%_drv.o,$(module-list))
# libs-objs are included in every module so that radical changes to the
# architecture of the DRM support library can be made at a later time.
#
# The downside is that each module is larger, and a system that uses
# more than one module (i.e., a dual-head system) will use more memory
# (but a system that uses exactly one module will use the same amount of
# memory).
#
# The upside is that if the DRM support library ever becomes insufficient
# for new families of cards, a new library can be implemented for those new
# cards without impacting the drivers for the old cards. This is significant,
# because testing architectural changes to old cards may be impossible, and
# may delay the implementation of a better architecture. We've traded slight
# memory waste (in the dual-head case) for greatly improved long-term
# maintainability.
