Hi
I try add to my core-image-rt image on a x86 arch my own IO driver. I have already my own recipe, for normal user space programs everything is working fine.
For the kernel space driver Yocto is missing at do_comile task the asm/atomic.h header file. I have searched for the atomic.h file and found a lot of them in the ./build/tmp/work folder. Yocto should use one of them for the right hardware architecture right? Or is the a something else I have forget to do?
Many thanks
Krystian

What Yocto branch are you using ?
atomic.h is placed in the right location by the kernel build, assuming
that your driver recipe has the proper dependencies. Without seeing
that recipe, it is hard to say more.

I'm using the fido branch. My iointerrupt.bb file looks as follow:
DESCRIPTION = "Simple IO-interrupt driver"
SECTION = "iointerrupt"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
PR = "r0"
SRC_URI = "file://drv_iointerrupt.c"
S = "${WORKDIR}"
do_compile() {
${CC} drv_iointerrupt.c -o iointerrupt
}
do_install() {
install -d ${D}${bindir}
install -m 0755 iointerrupt ${D}${bindir}
}
Thanks,
Krystian

Hi,
I am trying to do loadable kernel module development using the yocto produced sdk.
I can create the sdk and it works fine for application development.
There appears to be some header files missing for kernel module development.
These are the steps I went through ( I am using Beaglebone Black )
mkdir bb-yocto
cd bb-yocto
git clone -b daisy git://git.yoctoproject.org/poky.git
cd poky
source oe-init-build-env build
vi conf/local.conf
MACHINE ?= "beaglebone"
bitbake core-image-minimal
bitbake core-image-minimal -c populate_sdk
cd tmp/deploy/sdk
./poky-eglibc-x86_64-core-image-minimal-cortexa8hf-vfp-neon-toolchain-1.6.3.sh
some header files I want to use fro kernel module development like kernel.h, kdev_t.h appear in
/opt/poky/bb-linux/sysroots/cortexa8hf-vfp-neon-poky-linux-gnueabi/usr/include/linux
but some are missing like, module.h, device.h, cdev.h,uaccess.h.
Is there something else I need to do to get the missing files?
Thanks
Louis

And so I'm clear .. this is a standard .ko ? Or a userspace kernel driver ?
If you are looking for the internal kernel sources to be on the include
path, you need to reference STAGING_KERNEL_DIR (and something has to
depend on the kernel do_shared_workdir task to get the right bits
in place).
recipes-kernel/lttng/lttng-modules_2.6.1.bb
Is an example of both.

If the driver follows kernel conventions, then yes, you can write a
recipe that builds and packages the modules.
If you look in meta-skeleton, there is a hello-mod example of a kmod
recipe.
