Dear all,
Now I am trying to compile a driver module for my linux 2.6.16 kernel in
ML403 with CPU arch Powerpc 405. But when I include linux/module.h, and
then in module.h it includes linux/sched.h, and then in sched.h it includes
asm/param.h and asm/semaphore.h and asm/mmu.h......, the compiling errors
of "no such file or directory" appear. I found that there are NOT such
files in asm/ at all.(the asm/ is linked to asm-ppc/ for PPC405 arch) Where
are they then? I think when compiling modules, we must include
linux/module.h and then these asm/*.h files, right? Any implies are
appreciated. Thanks a lot for your telling.
Regards
Ming

Dear all,
Sorry that mmu.h is there. However ptrace.h, cputime.h and so on are not in
asm-ppc/.
Waiting for your telling...

How are you compiling? For 4xx, you still need to specify ARCH=ppc with
the make command. There is some makefile hackery that will then bring
in header files from asm-powerpc as needed.

In fact, I just try to compile the hello example in the book Linux Device
Driver chapter 2. The Makefile is listed as:
#Makefile
ifneq ($(KERNELRELEASE),)
obj-m := hello.o
else
KERNELDIR ?= /home/mingliu/linux-2.6.16
PWD := $(shell pwd)
default:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
endif
Also, I have specified ARCH = ppc in my Linux kernel. But it seems that
there is still some problem. Thanks for your suggestion.
Regards
Ming

It's usually easier if you add your module to your copy of the kernel
sources and build it along with all the other modules.

How can I do that? I don't know how can I configure my driver and compile
it as a module. Which option shall I choose to configure my driver as a
module in menuconfig? Sorry that I am new to linux and I am anxious for
your helpful telling...
Regards

You need to at least the following steps:
1. Add your module to an appropriate location in the source tree, e.g.
drivers/net/ or drivers/char/, or whereever it fits best depending on
what it does.
2. Edit the Makefile in that directory so your driver gets built, e.g.
by adding a line 'obj-m += your-driver.o'.
The optional but recommended steps are:
3. Add the driver to an appropriate Kconfig file, typically in the same
directory as your driver, and change your Makefile to
use 'obj-$(CONFIG_YOUR_DRIVER) += your-driver.o'.
4. Learn to use 'quilt', or a similar tool, to manage your patch against
the kernel.
5. If you ask questions on the mailing list, make sure everyone has access
to your patch, e.g. by uploading it to a web site.

Dear Arnd,
Thanks so much for your telling. I will do that soon.

Sorry that my ip driver is so customed and I don't think anyone will have
interest on that. :-) However maybe later I can integrate other drivers in
the linux tree.

Ming
