Linux Misc driver Boilerplate (LMB) is a very lightweight kernel module boilerplate for kernel development/testing.

Currently only tested on kernel versions: 5.3.0, 5.4.0, 5.18.1.

To build the kernel module, simply run:

$ make

By default it builds against the running kernel, if you want to change this adjust KDIR in Makefile.

You can then load the kernel module by running:

$ sudo insmod lmb.ko

You should then be able to see /dev/lmb_driver if everything worked correctly; check dmesg and look for the [LMB] prefix for logging information. Note the device will be r/w for root only usually.

To build the tests, just run:

make test
