[ptxdist] Local kernel tree config option

[ptxdist] Local kernel tree config option

[Andre Haupt]

Hi all,

I want to use a local kernel tree in my ptxdist project. I followed the
instructions in the pdf documentation (chapter 6.13). There, a 'Local
kernel tree' menu entry in the platform config is mentioned.

However, this entry is missing when i do a ptxdist platformconfig ->
Linux kernel.
What am i doing wrong here?

Btw, i use the git repository of ptxdist with the 'ptxdist-2011.08.x'
branch.


regards,

Andre

Never mind. I just found out that this was removed recently.

So to apply custom changes to a kernel, i create a folder <kernel.version>
in my-project/patches and put a quilt series with my changes in it,
right?

It was replaced with a more generic option. I guess we need to update the
docs:

$ ln -s /path/to/your/kernel/tree <BSP>/local_src/kernel.<platform-suffix>

If this path exists as a directory or link to a directory, then it will be
used instead of extracting the source. Note: this is a development feature.
When you're done, create the patches + series as you noted above and remove
the link.

I am sorry, but I can't seem to make it work.
I am using ptxdist 2011.12.0, and if I do
ptxdist kernelconfig, it will try to download the kernel.

I  straced the whole thing :
strace -f -o kernelconfig.log ptxdist kernelconfig

To find out why it was not finding my link
And could not find any occurence of local_src in it.

Please send the output of:

$ ls -l local_src/
$ ptxdist clean kernel
$ ptxdist extract kernel

AFAIK this is still done, although not necessary. Known bug, Robert wrote 
about it some time ago.
As you seem to have an own kernel name, I would just touch the file it wants 
to download in src/ and you should be fine.

Yes of course. The tarball is still needed. This is a development feature.
- Select the base kernel version in platformconfig (this will be downloaded)
- work on the kernel tree in local_src/kernel.<platform>
- export the final patches and remove local_src/kernel.<platform>

For something permanent it _may_ work to overwrite KERNEL_URL:

$ cat rules/post/fixup.make
KERNEL_URL := file://$(PTXDIST_WORKSPACE)/local_src/my-special-kernel
$

But I'm not sure if that really works for the kernel.

The local kernel tree option is a nice feature and thanks to this thread it 
worked for me first try. Do any of the other packages support this 
functionality? I am thinking specifically about barebox where I need to make 
many initial changes during development.

It works with any package. Just use <packagename> instead of "kernel".
