Hi
I'm having some trouble applying kernel patches.
I manually copied the kernel tar ball
into: /opt/buildroot/dl/linux-2.6.38-rc5.tar.bz2 and using "make menuconfig"
I specified the kernel version
.....however I'm having some problems applying my patches. Everything
compiles 100% if I patch "/opt/buildroot/output/toolchain/linux-2.6.38-rc5",
however I would
like it to apply my patches after extracting the tar ball from
"/opt/buildroot/dl/linux-2.6.38-rc5.tar.bz2" when I run "make"
I've tried placing my patches in:
/opt/buildroot/linux/kernel-patches/0001-linux-2.6.38-rc5.patch
I also tried putting them in
/opt/buildroot/package/linux/kernel-patches/0001-linux-2.6.38-rc5.patch
Using "make menuconfig" under specified custom patches I added:
linux/kernel-patches/0001-linux-2.6.38-rc5.patch
...but it won't apply the patch.
Any ideas?
Thanks

that is the Linux-headers directory. The _kernel_ gets compiled
under buildroot/output/build/linux-$(LINUX_VERSION).
So, are you having problems building the kernel-headers or the
kernel?

Hi Andy
I'm attempting to do a full build (uImage and rootfs)
I've got 6 kernel patches which I need to apply before running the "full
build", they add "board support" for my module and various other "nand"
related bits. One of the patches adds
"arch/arm/configs/telit_ge863_defconfig"

You should create a directory OUTSIDE the scope of the BuildRoot dirs
for your patches. It didn't occur to me until I went looking for
something else just now that buildroot/linux is a known directory.
Your patches could exist in buildroot/mylinux if you wanted, but you
shouldn't put stuff into dirs that BuildRoot knows.
So, you'll put your patches in mylinux then config the kernel patches
to the unqualified path starting in buildroot (or you could do something
along the lines of $(TOPDIR)/mylinux to be more BuildRoot friendly ;).

Hi,
You may have a path problem for your patches. The path should be given in your
*_defconfig.
And buildroot will automatically apply patches at the appropriate time if they
are named in the form linux*patch. See the makefile.
so 0001-linux-2.6.38-rc5.patch should be linux-001-2.6.38-rc5.patch
Regards, Steve

Could someone write a HOWTO?
I mean:
step 0): "I have kernel.xxx.yy.zzz directory unpacked AND a set of
patches (that applies correctly from kernel root) patch.00xx.patch"
step 1): where should I put (link?) kernel source?,
step 2): where should I put patches?.
step 3): how do I inform buildroot about patches?

It isn't that "dumbed down" but how about:
buildroot/docs/patches.html <Linux kernel section>?

Not sure it will answer the question, but what about:
http://buildroot.org/downloads/buildroot.html#board_support

I'm new to buildroot so probably don't understand it all yet.
From my perspective, my board is not supported, so my patches are more then
adding a "defconfig"
Perhaps: /opt/buildroot/linux/kernel-patches/<kernel
version>/<number-ordered-patch-details.patch>
would be easier then pasting patches into "make menuconfig"

I think I've got it working....doing a full build now.
This is what I did:
1. mkdir /opt/buildroot/linux/kernel-patches
2. name patches in the order that you want them applied, for example:
root at prodvarm:/opt/buildroot/linux/kernel-patches# ls -1
linux-2.6.38-rc5-0001.patch
linux-2.6.38-rc5-0002.patch
linux-2.6.38-rc5-0003.patch
linux-2.6.38-rc5-0004.patch
linux-2.6.38-rc5-0005.patch
linux-2.6.38-rc5-0006.patch
3. Create a list of patches to paste into the "Custom patches" option when
running "make menuconfig":
root at prodvarm:/opt/buildroot# find linux/kernel-patches/ | grep "\.patch" |
sort -n | xargs
linux/kernel-patches/linux-2.6.38-rc5-0001.patch
linux/kernel-patches/linux-2.6.38-rc5-0002.patch
linux/kernel-patches/linux-2.6.38-rc5-0003.patch
linux/kernel-patches/linux-2.6.38-rc5-0004.patch
linux/kernel-patches/linux-2.6.38-rc5-0005.patch
linux/kernel-patches/linux-2.6.38-rc5-0006.patch
root at prodvarm:/opt/buildroot#
4. run "make menuconfig", then go to kernel/custom patches option and paste
the "patch list" like so:
linux/kernel-patches/linux-2.6.38-rc5-0001.patch
linux/kernel-patches/linux-2.6.38-rc5-0002.patch
linux/kernel-patches/linux-2.6.38-rc5-0003.patch
linux/kernel-patches/linux-2.6.38-rc5-0004.patch
linux/kernel-patches/linux-2.6.38-rc5-0005.patch
linux/kernel-patches/linux-2.6.38-rc5-0006.patch
5. Make sure previous kernel bits have been removed:
rm -rf output/toolchain/linux-2.6.38-rc5 ; rm
-rf output/build/linux-2.6.38-rc5
6. "make"
After a while you'll see it extracting the kernel and then applying the
patches....although I've not tried to boot the resulting uImage yet....but
my boards ".._defconfig" was there and the build appeared to go through.
Thanks for the help!!!

This (for me) definitely indicates need of some HOWTO:
I find myself experienced Linux user/admen (but not a programmer), and
*.patch is still a mystery for me :(

You can put these kinds of files anywhere, but it seems to be the natural home
for board support packages.

This is a good organisation, even though in a recent Buildroot
(2011.02), the board-specific stuff would rather go into
board/<manufacturer>/<product>, and there would be no
board-specific Config.in and Makefile.in. The rest would look essential
the same.

Hi Thomas,
Looking at those two files, I guess Makefile.in could be replace with more
BR2_defines, but how do you replace a custom config system? I like to understand
"the plan" and I will try to comply with the design.

Do the following :
mkdir board/bruce_company/bruce_product/linux
cp ALL_YOUR_PATCHES board/bruce_company/bruce_product/linux
All patches must have filenames that start with "linux-".
Then, run make menuconfig, and use the following options :
Kernel
-> Linux Kernel
-> Kernel version (Custom version)
-> (2.6.XX) Kernel version
-> (board/bruce_company/bruce_product/linux) Custom kernel patches
Of course, make sure your patches match the selected kernel version.
Then, in order to save your configuration and make it a default :
make savedefconfig
mv defconfig configs/bruce_product_defconfig
Now, you can build Buildroot with:
make bruce_product_defconfig
make
Regards,
Thomas
