# 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.

|
