I must be dense. There's a Makefile already in the source dir that includes
the desired module name, but dkms wants a -v parameter, and man dkms gives me
no idea what a module-version is in this context of a module build. :-(
(yes, as Craig noted, I'm one of the authors, and maintainer for
DMKS).
DKMS makes a few assumptions.
1) the source code needs to be in a directory
/usr/src/<modulename>-<moduleversion>. So, /usr/src/foo-1.0 for
module foo version 1.0. The version field generally matches what's in
the MODULE_VERSION() tag of the source code.
2) in that directory, there needs to be a brief dkms.conf file that
looks like:
PACKAGE_NAME="foo"
PACKAGE_VERSION="1.0"
BUILT_MODULE_NAME[0]="foo"
DEST_MODULE_LOCATION[0]="/kernel/drivers/net"
(it can get fancier, but that's enough for most modules).
Then you execute:
# dkms add -m foo -v 1.0
# dkms build -m foo -v 1.0
# dkms install -m foo -v 1.0
This builds and installs module foo version 1.0 into your currently
running kernel's /lib/modules/ tree. If you need to build for a
different kernel than the currently running kernel (or architecture):
# dkms build -m foo -v 1.0 -k $kernelver -a $arch
# dkms install -m foo -v 1.0 -k $kernelver -a $arch
Thanks,
Matt
