[PATCH v3] dkms: Add new recipe for supporting dkms


Alexandru Vasiu <alexandru.vasiu@...>
 

Dkms is a tool used to compile out of tree modules directly on
target devices (sometimes you have sources or binaries which
need to be compiled directly on target, outside OE).
I used a simple module and a dkms config to test it, and dkms
compiled and installed the module on target.

For example:
.
├── dkms.conf
└── src
├── hello.c
└── Makefile

hello.c:
#include <linux/module.h>

int init_module(void)
{
printk("Hello World!\n");
return 0;
}

void cleanup_module(void)
{
printk("Goodbye Cruel World!\n");
}

MODULE_LICENSE("GPL");

Makefile:
obj-m += hello.o

KERNELDIR ?= /lib/modules/$(shell uname -r)/build

PWD := $(shell pwd)

install:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules

clean:
rm -rf *.o *.ko *~ core .depend .*.cmd *.mod.c modules.order Module.symvers

dkms.conf:
MAKE="make -C src/ KERNELDIR=/lib/modules/${kernelver}/build"
CLEAN="make -C src/ clean"
BUILT_MODULE_NAME=hello
DEST_MODULE_LOCATION=/kernel/drivers/scsi
BUILT_MODULE_LOCATION=src/
PACKAGE_NAME=hello
PACKAGE_VERSION=0.1
AUTOINSTALL=yes
REMAKE_INITRD=yes

All files should be in /usr/src/<package-name>-<package-version>,
in our case in /urs/src/hello-0.1.
