Re: [Angstrom-devel] what file kernel configuration really uses?
There is another question, I think I mentioned it earlier also in this
chain. I have also asked it in other time as own subject. No-one seems to
have opinion about that.
Koen, you might know, if it is a "feature" misbehaviour or problem in my
set-up.
For instance when I ran those tests I did first "fetch". Then I ran
"unpack". Unpacking ran again fetch and then unpack. Then I ran "patch".
Again, at least unpack was run again and then patch. Similar behaviour
seems to happen with "configure" so that patch will be run again even
though it had been ran manually before. This feature makes paching quite
awkward as if I edit some file that has been unpacked and applied with
other patches, that will be written over when running "configure" or
"compile" to check how edits worked.
I always get two warnings when I run bitbake:
WARNING: No recipes available for:
/home/sw/cpr3/oe/sources/meta-handheld/recipes-core/udev/udev_164.bbappend
/home/sw/cpr3/oe/sources/meta-intel/meta-fri2/recipes-core/tiny-init/tiny-init.bbappend
But I suppose they are nothing to do with this issue.
So, Is this something that should happen or should I try to find set-up
problem of some kind?
Thanks,
Matti

Instead there are three of them:
0002-add-defconfig-file-to-use-as-.config.patch
0044-am33xx-Add-default-config.patch
0073-defconfig-Update-bone-default-config.patch
Quoted from oe_manual "The patch will be applied from the unpacked source
directory, ${S}".
Above patches create and modify defconfig file. 0002-add created it and
next two tweak it slightly. I double checked this by first deleting:
${WORKDIR}/defconfig and ${S}/defconfig and then running:
bitbake -f -c unpack linux-mainline
At this point there is ${WORKDIR}/defconfig that my layer provides.
Then I run:
bitbake -f -c patch linux-mainline
Now there is also ${S}/defconfig.
Then I executed patches with those three patch files in quite a different
place - and that produced there defconfig file that was identical with
${S}/defconfig. BTW Koen, please check who has signed off:
https://github.com/beagleboard/meta-beagleboard/blob/master/common-bsp/recipes-kernel/linux/linux-mainline-3.8/not-capebus/0002-add-defconfig-file-to-use-as-.config.patch
He might be someone you know :-)
So, I would say OE produces ${S}/defconfig.

Re: [Angstrom-devel] what file kernel configuration really uses?
Ulf,
I'm not quite sure what you mean.
I've understood that layers (read layer.conf files) are scanned through
using locations and order found in BBLAYERS variable set in bblayers.conf
file. BBPATH is initialized in bblayers.conf as ${TOPDIR}. Thereafter (my
wild guess) BBPATH is appended (or prepended) with values given in the the
layer.conf files. I switched to prepending and it did not help this issue.
I have set my layer as the first instance in BBLAYERS variable whereas
meta-beagleboard/common-bsp is somewhere in the middle. My layer is using
prepending when assigning in BBPATH (should be the first instance also in
BBPATH) whereas meta-beagleboard/common-bsp uses appending. Therefore, my
layer should be handled before meta-beagleboard/common-bsp, should it not?
I may have understood this all wrong, though.
Regards,
Matti

Re: [Angstrom-devel] what file kernel configuration really uses?
You are looking in the wrong file.
In Angstrom, you need to change BBPATH in setup-scripts/conf/bblayers.conf
Not in the layer.conf in your own layer.

I replaced
FILESEXTRAPATHS_prepend := "${THISDIR}/linux-mainline-3.8:"
with
FILESPATH_prepend := "${THISDIR}/linux-mainline-3.8:"
in my bbappend file and now ${WORKDIR}/defconfig is coming from my metadata.
Now this looks mych better!

It did not help chnging BBPATH in layer.conf
It used to be
BBPATH .= ":${LAYERDIR}"
and I changed it to:
BBPATH =. "${LAYERDIR}:"
It still fetches beaglebone's defconfig.
Should I change my bbappend file instad not using FILESEXTRAPATHS_prepend
but using FILESPATH_prepend instead?
Do FILESPATH have precedence over FILESEXTRAPATHS?

what do you mean ? defconfig is provided as any other file and then munged over
in WORKDIR to make a .config
usually you would keep the complete defconfig in your layer and use
it. You would start
with the given reference defconfig and tweak it to your interest and then do
make savedefconfig
which should generate a defconfig like arch/arm/configs which then you
can save as a defconfig
file in your layer and use it to replace the defconfig file that
meta-beagleboard is providing

for conf and include files it will use the BBPATH and not priority
which means your layer should appear before meta-beagleboard in BBPATH
order.

It is used to create the ".config" file in the kernel source directory.
If you modify the ".config" file, you will see changes in the kernel
file.
if you modify the defconfig file in the build directory, nothing happens.
I typically change the ".config" and copy the result to the "defconfig"
in
the
meta-layer. Then I rebuild from scratch.

Re: [Angstrom-devel] what file kernel configuration really uses?
Hi Ulf,
Yes, linux.inc seems doing the job as you told - this clears a lot. I had
been patching wrong file:${S}/defconfig instead of ${WORKDIR}/defconfig.
It seems that I'm not alone with this mistake. ${S}/defconfig seems to be
created by two patches:
0002-add-defconfig-file-to-use-as-.config.patch makes skeleton and
0073-defconfig-Update-bone-default-config.patch makes some modefications.
${WORKDIR}/defconfig (important one) is most likely coming from
./linux/linux-mainline-3.8/beaglebone/defconfig as there is only one
difference that could have come from configuration process.
It seems that configuration fragments do not work in regular Angstrom - I
suppose they are just Yocto stuff.
Providing defconfig directly did not work - most likely it was written over
by the patching the seems creating the ${WORKDIR}/defconfig
Downside is that my beaglebone version of defconfig seems to get used
instead of mine even though my layer should have higher priority. I hope
this is the last thing I should cleared.
Thanks,
Matti

I have problem that changes in defconfig are not seen in kernel
features.
Instead they seem the same that are in .config file
I have tried configuration fragments, patches and providing defconfig
directly.
They all seem to give proper defconfig. However, menuconfig never
provide
the changed configurations. Also, for instance when I try to configure
HW
EEC operation for NAND flash using CONFIG_MTD_NAND_OMAP_BCH.
omap2.c reports that "CONFIG_MTD_NAND_OMAP_BCH is not enabled".
I've been workin on beaglebone variant - layer over beaglebone.
Build Configuration:
BB_VERSION= "1.17.0"
TARGET_ARCH = "arm"
TARGET_OS = "linux-gnueabi"
MACHINE = "beaglebone"
DISTRO= "angstrom"
DISTRO_VERSION= "v2012.12"
TUNE_FEATURES = "armv7a vfp neon cortexa8"
TARGET_FPU= "vfp-neon"
oe_sitecno
oe_emergence = ":"
meta-angstrom =
"angstrom-v2012.12-yocto1.3:**b7f8207b94d9a0ece73ad212a193cb**
2c95bd17ee"
These setting give kernel 3.8.11.
Is there something I have missed?
Thanks in advance,
Matti

patching defconfig in the kernel build directory, providing defconfig in

Kernel development manual - give the same outcome in the defconfig at the

What is happening is dependent on the kernel recipe.
Typically, you find that "linux.inc" does the job,
and in "do_configure", which is run when you do:
bitbake -c configure virtual/kernel
${WORKDIR}/defconfig is altered to ensure it makes sense.
A lot of options are simply deleted.
${S}/.config" is created as an empty file and then the deleted options
are added with a proper value.
At the end, defconfig is appended to the "${S}/.config
so when you run
bitbake -c configure virtual/kernel
both ${WORKDIR}/defconfig and ${S}/.config are changed.
/Ulf
What command do you use when you are using .config directly? My experience
is that when I for instance run:
bitbake -f -c configure virtual/kernel
after
bitbake -f -c patch virtual/kernel
bitbake executes again do_patch, that at least rides over defconfig if I
edited that.
In fact it seems that "bitbake -c config" runs always do_patch even if
previous command was patch and no modifications were in between.

The "defconfig" file is present in the meta-layers and copied to the
kernel build directory.
It is used to create the ".config" file in the kernel source directory.
If you modify the ".config" file, you will see changes in the kernel file.
if you modify the defconfig file in the build directory, nothing happens.

Re: [Angstrom-devel] what file kernel configuration really uses?
Thanks Ulf, It seems to work in that way. However, I'm a bit surprised that it works so as as I mentioned above all the procedures - patching defconfig in the kernel build directory, providing defconfig in metadata and providing configuration fragments as described in the Yocto Kernel development manual - give the same outcome in the defconfig at the kernel build directory. What command do you use when you are using .config directly? My experience is that when I for instance run: bitbake -f -c configure virtual/kernel after bitbake -f -c patch virtual/kernel bitbake executes again do_patch, that at least rides over defconfig if I edited that. In fact it seems that "bitbake -c config" runs always do_patch even if previous command was patch and no modifications were in between.
