# KBUILD Makefile for the NVIDIA Linux kernel module.
#
# The motivation for replacing the original Makefile is the hope that this
# version will simplify the build and installation process. In the past,
# many architectural and cosmetic changes to the Linux kernel have made it
# difficult to maintain compatibility or required duplication of logic.
#
# Linux 2.6 introduces numerous such changes, many of which impact modules.
# Relying on KBUILD, some aspects of the build system otherwise difficult
# to support (for example, module versioning) are abstracted away and dealt
# with elsewhere, making life significantly easier here.
#
# The new approach currently has its own share of problems, some of which
# are architectural difficulties with KBUILD, others minor annoyances. For
# this reason, an improved version of the NVIDIA Makefile is available to
# those experiencing difficulties.
#
# kbuild Makefile originally developed by:
#
# Alistair J Strachan (alistair@devzero.co.uk) (first pass, enhancements)
# Christian Zander (zander@mail.minion.de) (enhancements)

MODULE_BASENAME := nvidia

# 
# This suffix is used to construct the name of the NVIDIA kernel module
# in case of multiple kernel module builds. This suffix can either take the 
# numeric value 0-7 or the string "frontend". For normal NVIDIA kernel module 
# builds, this variable is empty and hence the module name is identical to 
# the base names.
#

NV_MODULE_SUFFIX ?=

#
# The NVIDIA kernel module name and static file names. In case of multiple 
# NVIDIA kernel module builds, $(NV_MODULE_SUFFIX) is appended to the 
# module basename to construct the module name of the concerned module. 
# KBUILD will go ahead and append ".o" or ".ko" to form the module file name.
