Evgeni's private DKMS playground

Do not touch until I tell you to!

Prerequisites

1. You need to create a new binary package your-module-dkms

2. This package needs a Depends: dkms (>= 1.95)

dkms.conf(.in)

PACKAGE_NAME="your-module"
PACKAGE_VERSION="__VERSION__"
MAKE[0]="make -C ${kernel_source_dir} M=${dkms_tree}/${PACKAGE_NAME}/${PACKAGE_VERSION}/build"
CLEAN="make -C ${kernel_source_dir} M=${dkms_tree}/${PACKAGE_NAME}/${PACKAGE_VERSION}/build clean"
AUTOINSTALL=yes
BUILT_MODULE_NAME[0]="your_module"
DEST_MODULE_LOCATION[0]=/extra

• You basically only have to change PACKAGE_NAME

• BUILT_MODULE_NAME[#] is only needed when your module name differs from the PACKAGE_NAME (i.e. your_module vs, your-module) OR your package contains multiple modules

• DEST_MODULE_LOCATION[#] is needed for every module you build, but will be ignored (dkms installs everything in /updates/dkms/)

• AUTOINSTALL=yes triggers an automated build when booting a new kernel, useful, but not required
